  • 2017 Factory of the Future in Belgium operates with Dinnissen mixers

    Nuscience’s new factory in Ghent for producing premixes, young animal feed and specialties, has been named as this year’s "Factory of the Future 4.0”. A prestigious prize, which is being awarded to future-oriented manufacturers that meet the challenges of the fourth industrial revolution. What’s remarkable is that almost all of the production capacity of 10,000 tonnes per month is achieved using 11 Dinnissen mixers with a variety of specifications.

    The plant was commissioned at the end of 2015 to replace the locations in Baasrode and Drongen. Chris Mercier, COO of the Nuscience Group on the reason for this: "We are constantly looking for opportunities to lower costs, improve product quality even further, while simultaneously increasing the efficiency and flexibility of production. We were unable to optimise further in the two old plants, particularly owing to the constraints of the buildings and layout of the factories. This investment significantly reduces our operating costs."
    The Nuscience plant in Ghent has to be a real all-rounder in terms of production techniques and end products. A complete range of 'young animal nutrition' under the name Nutrition4U leaves the factory daily, as well as many premixes. Nuscience works with 350 different types of raw materials and more than 2,000 current recipes.

    Chris Mercier: “In terms of production, we are effectively unlimited: all kinds of different products, with solid and liquid additives. We have nine separate mixing lines; this in order to prevent contamination. These nine mixing lines each have their own specifications and they also have the benefit of overcapacity. This enables us to respond adeptly to peaks and toughs in demand.” The Dinnissen mixers are also tailored to this in terms of capacity and specific characteristics. There are 11 mixers set up with capacities ranging from 400 to 2400 litres. One of the mixers is made of manganese steel and is used especially for abrasive materials; others are made of 304 or 316 stainless steel. Since there is a whole a range of options for the Pegasus® mixers, there is always a suitable version to be set up.

    The choice for Dinnissen mixers is evident to Chris Mercier: "Our experience with Dinnissen mixers is such that it was immediately clear that we also wanted to have them in the new plant. The well-thought-out concept and the solid design, work excellently in practice and the mixers are extremely reliable. We are already familiar with the operational costs in terms of maintenance and cleaning and have of course included these in our considerations.”

  • Major manufacturer in the starch industry uses sifters of Dinnissen

    EVS Distribution, Dinnissen’s partner in France, has delivered tailor-made sifters to one of the major manufacturers in the starch industry. According to the demand of the customer this special sifter should prevent cross contamination by means of improved inspection methods. The solution was a new innovation of Dinnissen; the Wingdoor sifter.

    Innovation is in our DNA. Developing a new sifter with improved inspection methods to prevent cross contamination was a challenging task that Dinnissen was happy to accept. Thanks to the extensive experience and expertise, the engineers at Dinnissen developed the custom-made Wingdoor sifter; a perfect combination of innovative power and the sieving process. The major advantage of this machine is that the doors can now open over the entire length of the machine. Therefore, the sieve does not need to be driven out for inspection, so that cross contamination is prevented. The replacement of the sieve mesh is naturally very efficient because the sieve basket can still be moved out of the machine. In addition, the Wingdoor sifter can reach capacities up to 30 tonnes per hour depending on the product.

    By delivering in coordination with the customers’ planning, Dinnissen was able to optimally respond to the clients’ schedule. In addition, the client had prepared all surrounding equipment and subsequently the Wingdoor sifter was installed with the help of detailed 3D drawings of Dinnissen. This successful installation was made possible due to the fruitful cooperation between Dinnissen Process Technology and EVS Distribution. For the last five years, EVS Distribution has already sold numerous Dinnissen machines.

  • Dinnissen’s new hammer mill offers producers of feed and pet food greater capacity and flexibility

    Innovative automatic screen exchanger combined with ingenious screen design

    Dinnissen Process Technology specializes in the development and production of process technologies for the feed, food, pharma and chemical industries. Dinnissen offers a wide range of crushers, hammer mills, roller mills, and knife mills for grinding, crushing and micronizing a wide variety of ingredients. Dinnissen’s newest hammer mill is equipped with increased screen surface, extra-large grinding panels, and an automatic screen exchanger in combination with a wide range of screens. As a result, the newest hammer mill provides clients with significantly increased grinding capacity, less downtime, and greater flexibility.

    Hammer mills are especially suited for grinding soft to medium-hard products such as grains, raw ingredients containing proteins, and minerals down to particle sizes of between 3 mm and 150 µ. In Dinnissen’s hammer mills, freely suspended hammers rotate at high speed inside the grinding chamber. Depending upon the components being ground down, single hammers or double hammers can be used. The centrifugal force produced by the rotating hammers crushes the product into smaller particles against special grinding panels on the inside of the grinding chamber, after which the processed product passes through special screening panels before exiting the hammer mill. The screen surface and perforations determine the capacity, quality and effectiveness of the screening process, which is why Dinnissen has made significant investments in developing innovative solutions in this area.

    Dinnissen’s new hammer mill features an ingenious and innovative design which significantly increases the surface area of the grinding panels as well as screen panels inside the hammer mill. This results in increased grinding as well as screening capacity. In addition, the screen storage facility is fitted with an extra-wide chamber, making it easier to carry out maintenance and replace damaged screens whenever necessary. This in turn reduces downtime during maintenance stops and increases the overall efficiency of the new hammer mill. The maximum speed of the new system is 1500 revolutions per minute, which means that it has a longer usable lifetime and is more energy-efficient than its predecessors. The built-in magnets and traps for unwanted hard objects also prevent damage to the screens from the presence of iron objects or other hard materials. This also increases the efficiency of the new hammer mill at a very low noise level.

    Dinnissen has designed a new and innovative screen changing system for its newest hammer mill, which offers increased speed, ease-of-use and reliability to clients who regularly switch between different ingredients and product specifications. The automatic screen exchanger has enough space for 4 to 6 sets of different screen panels, making it possible for the system to automatically select the appropriate screen perforation and thereby grind the raw ingredients into the desired product within optimum structure and particle size. The mechatronic screen exchanger system automatically chooses and places the correct set of screen panels in the hammer mill. After completion of the production process, the screen exchanger also removes and stores the set of screens within 40 seconds. This makes it possible to change from one set of screens to another very quickly and efficiently and greatly reduces downtime. It also greatly reduces the risk of the wrong screen panels being used. The automatic screen exchanger can also be fitted with a screen detection system, making it possible to identify and report the right selection to the control room.

  • High-capacity powder screening system with integrated metal detection and sampling functionality for smaller and medium-sized food companies

    Dinnissen Process Technology is specialized in the processing of high-quality powders, particles and granulates for food producers such as Nestlé, Pepsico, Danone and Friesland Campina. To help these clients comply with the increasingly rigorous requirements for food safety, hygiene and quality, Dinnissen developed a special line of high-capacity powder screening systems with built-in metal detection and automatic sampling functionality. As increasing numbers of smaller and medium-sized food companies also aim to or have to comply with the most rigorous requirements, Dinnissen has also developed an affordable screening solution for these clients as well.

    The new screening concept offered by Dinnissen Process Technology was developed for smaller and medium-sized companies that wish to quickly and efficiently carry out thorough quality controls on powders such as milk, starch, and cocoa powders. The new screening concept allows food producers to screen fine powders (≤ 100 mµ, 250 mµ or 1000 mµ) at very high throughput rates (up to 30 to 40 tons per hour), thereby avoiding product contamination and ensuring that the end product complies with the desired justifications. The new screening system is based on a centrifugal screen, whereby the ingredients being processed are introduced into the screening chamber via a special built-in transport system and then suspended via rotating blades. The centrifugal force ensures that larger particles are immediately transported onwards and removed whereas finer particles are allowed to pass through the appropriate screen. Depending upon the specific product, process and capacity desired, it is also possible to work with a flat screen. By using various combinations of rotational speed, screen perforation size, and screen length, practically any desired screening result can be realized. Screening throughput rates of up to 15 or even 70 tons per hour can be realized, and even the very finest powders, from 5µ to 1000 µ, can be processed quickly and efficiently. Built-in metal detectors protect the screens against damage.

    As increasing numbers of companies aim to and/or have to comply with increasingly rigorous requirements in terms of (food) safety and quality, Dinnissen has equipped its new screening system with integrated and automated sampling functionality. This allows the user to automatically take samples to monitor product quality in terms of microbiology, homogeneity, and particle size. Samples can be taken in accordance with a predetermined frequency, volume and weight, thereby increasing the reliability, accuracy, and efficiency of the overall quality control process. The new sampling system introduced by Dinnissen can take samples ranging in size from 25 g to 1000 g per sample and can be cleaned very easily and quickly, thereby preventing contamination of the product flow and/or samples. Another advantage of the integrated automated sampling system is that it reduces the amount of manual labour required for quality control activities.

  • Process technology for Lean Six Sigma companies

    Dinnissen Process Technology specializes in technologies for receiving, transporting, weighing, mixing, grinding, sifting, vacuum coating, and packaging bulk solids for a wide range of markets. The production companies we serve are increasingly working in accordance with Lean Six Sigma, a methodology used all over the world that aims to improve efficiency and eliminate waste and activities not valued by the client. Dinnissen is developing process technology, process designs, and intelligent process automation specifically for these clients.

    Specialized process technology for Lean Six Sigma companies.
    Production companies working in accordance with Lean Six Sigma methodology have six solutions available to ensure that their organization can work more cheaply, more customer-focused, and more efficiently. Technology is one of the most important of these solutions. Dinnissen Process Technology offers Lean Six Sigma companies specialized technology that contributes to these efforts. For example, compact equipment offering high production capacity and ease of access requires a lower initial investment and can also be cleaned more easily and quickly. Dinnissen’s Lean Mixing Concept allows companies to realize savings in terms of energy, labour, physical space, and investment costs for transport and storage systems by utilizing innovative and simplified gravity-based transport technology. Multifunctional mixers and vacuum coaters are also cheaper to purchase and operate and require less space and labour. They also offer production companies, now and in future, a great deal of flexibility to make exactly those products that are most highly appreciated by their clients. Other process technologies focus on aspects such as energy savings, minimizing damage to fragile ingredients, product homogeneity, and hygiene.

    Process design for Lean Six Sigma companies in four steps.
    Dinnissen Process offers companies looking to purchase one or more machines a specialized development plan, providing them with certainty upfront and the opportunity to measure the results achieved and fine tune the technology. Every request for a tailor-made piece of process technology is first subjected by Dinnissen to a factory acceptance (FAT) test at its in-house D-Innocenter®. At this testing site, products submitted by clients are tested in combination with Dinnissen’s existing process technology. These tests make it clear whether the technology chosen is suitable and how it can best be applied. After the client-specific installation has been produced, mechanical tests are carried out to determine whether the technical installation functions optimally before delivery to the client. After delivery and installation in the overall production line, the site acceptancetest (SAT) is carried out. Extensive test runs are carried out using the process technology delivered under all desired sets of conditions and with all desired raw materials and ingredients. Dinnissen goes through every test run together with its client until the results are approved by the client.

    Data analysis for process automation and intelligent production processes.
    The ability to analyse data is another important resource for Lean Six Sigma companies. Dinnissen automates the entire production process to provide an optimum, intelligent, and self-regulating production process. It provides PLC controls for machines and transport systems at the field level as well as links to process controllers, variable speed drives, and master control centres in the company network. Dinnissen organizes the collection, forwarding, processing, and visualization of measurement and control signals from production processes via SCADA systems. In doing so, it visualizes measurement data in operator and control rooms and makes it easier for the company to manage its production process more effectively and efficiently. This also simplifies the preparation of reports and the installation and operation of alarm circuits. Dinnissen implements its automation projects using the communication protocols of commonly used ERP systems such as SAP and Oracle, which means that linking and integration should not be a problem. The users of automated systems are also provided with remote control facilities to monitor and control production processes from a distance.

    By developing process technology for companies that work in accordance with Lean Six Sigma, Dinnissen can also provide other clients with additional benefits and services. These benefits will be the result of increased in-house knowledge and the availability of innovative technology enabling companies to work more efficiently, more cheaply, and with a greater focus on what the client actually wants.

  • Lean Mixing process with innovative transport of powders, granules and granulates

    Easier to integrate, gentler and less expensive mixing concept.

    Dinnissen Process Technology has already built an enviable reputation for delivering sophisticated solutions for mixing powders, granules and granulates. During the EasyFairs Solids in Rotterdam, Dinnissen is launching its new Lean Mixing concept with a new and integrated transport system that can be more easily integrated and is gentler and less expensive than the pneumatic transport systems now commonly in use.

    Total mixing concept without the disadvantages of pneumatic transport.
    The Lean Mixing concept offers a total and integrated solution for mixing powders, granules and granulates, including a highly effective and efficient system for transporting the raw ingredients as well as the finished product. This new concept allows for a totally integrated mixing and transport process without having to resort to pneumatic transport with allthe related disadvantages such as increased risk of product damage, higher energy costs, higher contamination risks, and extra handling. LeanMixing utilizes big bags in which the ingredients have to be lifted only once. Once the big bags are hoisted, they are transported via an automatic route guidance system to the proper unloading position on the transfer station and unloaded. The process operator then attaches the big bags to the discharging stations in a particle-free environment, connecting them to Feeder Valves specially developed by Dinnissen. These cost-efficient and fully integrated dosage valves ensure that the dosage ingredients are precisely weighed out when leaving the bag or entering the production process and can handle a wide range of capacities from 6 kg per hour to as much as 50 tons per hour.

    Cost-efficient and Easy-to-Clean mixing method
    The LeanMixing Concept also integrates the well-known double-shaft Pegasus® Mixer, which gently suspends powders, granules and granulates in the air while mixing them. The unique fluidized zone that is created in the process makes this multifunctional processing unit the perfect tool for mixing ingredients extremely accurately, gently, quickly, and energy-efficiently. After the mixing process, the finished product goes through an automatic metal check and sieve check, after which it is transported further via an automated big bag filling system or a filling system optimized for the final packaging step. If desired, this can be carried out in a high-care environment. These processes are also carried out with the help of gravity, thereby saving energy and minimizing the use of moving parts. Last but not least, the LeanMixing Concept is also designed to be very Easy-to-Clean, which is why the mixer, hopper, sieve, and metal check unit are all fitted with a side guidance system, making it possible to easily and quickly access and clean all interior parts and components.

    Higher-quality end product
    Dinnissen’s LeanMixing concept is easier to integrate into existing production processes and also requires significantly less space when set up in a new environment. Initial investment costs are therefore much lower. Lean Mixing consumes less energy and is easier to clean than comparable pneumatic transport systems and therefore reduces operating costs. As the transport process is extremely gentle, the materials handled, including powders, granules and granulates, suffer less breakage and damage, resulting in a higher-quality end product.

  • Innovative system for residue-free emptying of bags

    Improves hygiene and prevents loss of ingredients.

    Companies that take delivery of the ingredients used for their production processes in bags of between 10 kg and 90 kg actually lose between 0.4% and 1% of these often expensive ingredients due to the residues left behind when the bags are emptied. Dinnissen Process Technology has developed a new system for emptying such bags especially for these companies. With this system, companies can remove up to 99.9% of the contents when emptying these bags. By doing so, they not only prevent the loss of these ingredients but also improve hygiene and working conditions in a great many ways in and around the production area.

    Removes up to 99.9% of bag contents via vibration-, air pulse-, and suction- based technology.
    Dinnissen’s new system is suitable for bags of 10 kg to 90 kg and empties them down to practically the last particle. The bag emptier prevents contamination within the production process and also prevents the ingredients from being dispersed into the surroundings. The system is particularly well-suited for processing expensive and contamination-sensitive ingredients such as coffee, tea, milk powders, baby foods, and raw materials used in the chemical, pharmaceutical, and cosmetic sectors. The new system also proves its worth in situations where the ability to empty bags without leaving any residues behind results in lower waste disposal rates. The new bag emptying system automatically cleans the outside surface of the bag using pulsed air and brushes before opening the bag, thereby preventing surface dirt and contaminants from entering the production process. The bag is then placed and held in the bag emptier and completely cut open, thereby eliminating the possibility of contamination with the packaging materials. The bag is then emptied by vibrating it and blowing it clean at the same time. A compressed air cleaning system can be used to that effect. A sophisticated vacuum suction system ensures that no particles escape from the bag emptier. The ingredients sucked up by the suction system are carefully collected and utilized for the production process. For moisture-sensitive powders, particles or granulates, specially conditioned dry air can be used to prevent clumping and degradation. After the bag has been completely emptied, it is automatically carted off. As the bags are residue-free, the production environment remains clean and hygienic. If desired, the empty bags can be pressed together into plastic foil to minimize waste volumes and waste removal costs.

    Suitable for a wide range of ingredients.
    Dinnissen’s new bag emptying system is suitable for bags of 10 kg to 90 kg of all types and sizes and can be used with ingredients that have a wide range of product and transport characteristics.

  • Automated container tipper for residue-free emptying of containers with hazardous substances

    Dinnissen Process Technology has developed an automated container tipper for emptying containers with hazardous substances inside a closed housing. Via this innovative solution, Dinnissen aims to offer process operators an optimum level of safety and the ability to empty containers without leaving any residue behind. The container tipper will be on show at the EasyFairs Solids in Rotterdam.

    Optimum safety and stress-free operation for the operator.
    Companies in the chemical, pharmaceutical, recycling, and petrochemical industries often process hazardous substances in drums and octabins. The process of emptying such containers is physically stressful and also hazardous due to the toxic and irritating properties of the contents. The container tipper has been specially developed to automatically tip the container and empty it safely and efficiently without leaving any residue behind. This even applies to situations in which the container has an inner lining or in which the contents consist of chunky, sticky, or finely dispersed particulate materials. The containers can be inserted into the tipper manually or in a fully automated fashion via roller lines. After the exterior housing has been closed, the containers are connected via a system using double seals. Only after the container has been hermetically connected to the system, is it opened and rotated by 180°. The container is then emptied, without leaving any residue behind, using vibration-, air pulse-, and vacuum- based technology. For containers with an inner liner, Dinnissen has developed a special clamping system which holds the liner in place during the emptying process. The automatic container tipper can be expanded to include a weighing system which monitors the process and ensures that the container does not contain any residues. The automatic container tipper can be used for drums and octabins of all types and sizes.

  • Dinnissen presents energy-efficient drying in Pegasus® Mixer

    Dinnissen has added a new and extremely energy-efficient functionality to its multifunctional Pegasus® Mixer for drying bulk solids. This innovative technology, will enable users to realize significant savings in terms of production space and the purchase of separate installations. The new technology also ensures that powders, granules and granulates do not form clumps and are not damaged during the drying process in the Pegasus® Mixer.

    Double-shaft paddle mechanism creates mechanical Fluid Bed.
    The double-shaft Pegasus® Mixer is one of the most popular products sold by Dinnissen Process Technology, thanks to its double-shaft paddle mechanism which ensures that powders, granules and granulates are gently thrown into the air during the mixing process. This mixing process enables the Pegasus® Mixer to provide the user with some unique benefits. The fluidized zone created during the process allows the multifunctional processing unit to mix ingredients extremely gently, quickly and energy-efficiently. The new drying functionality built into the Pegasus® Mixer also takes advantage of this unique fluidized zone.

    No air pressure or capacity needed for creation of Fluid Bed.
    The double paddles rotating in opposite directions inside the multifunctional Pegasus® Mixer suspend the ingredients gently via a low-shear process that consumes very little energy and that results in practically no product breakage or degradation. At the exact moment that the ingredients are gently thrown into the air, warm air is injected or sucked into the process unit for the drying process. This can be implemented during or just after the mixing process. As a result, the suspended particles come into very close contact with the warm air and are dried easily, quickly and efficiently. The mixing of dry and warm air with the ingredients in the fluidized zone requires no pressure and greatly reduces the amount of warm air needed per hour, making the entire process extremely energy-efficient. It also ensures that ingredients such as powders, granules and granulates do not clump together or become damaged during the drying process in the mixer. The ability to simultaneously carry out two different processes in a single compact mixing unit that can be quickly and thoroughly cleaned provides the user with significant benefits. Of course, the ability to dry ingredients inside the multifunctional unit also reduces the amount of space required for the production process and makes it unnecessary to purchase separate equipment for the drying process. The sophisticated operating controls of the Pegasus® Unit make it an extremely flexible production tool, allowing users to quickly and easily adjust the settings for the drying functionality as well as the mixing time and intensity. As a result, the mixer can be used within a single production line for producing a wide range of different products, and the user can also easily switch between recipes, regardless of whether large or small batches are involved.

  • Dinnissen showcases its newest Dima® 200 bag emptier

    For safely and efficiently discharging fine particles.

    Dinnissen Process Technology has developed a new version of the classic Dima® 200 bag emptier for safely and efficiently emptying bags filled with fine powders, particles or granulates. The new model, which makes it possible to automatically empty bags while releasing less than 0.1 mg of product per m3 of discharged product, is intended primarily for companies that need to create a safe working environment for their operators in a wide range of sectors.

    Fully automatic bag emptier focuses on operator safety.
    Governments are applying increasingly stringent standards when it comes to the release of fine and ultrafine particles. As a result, companies are also increasingly being confronted with the challenge of having to prevent the release of even very small quantities of fine particles when bags need to be emptied. In response to these requirements, Dinnissen Process Technology has developed a new ultrafine version of the classic Dima® 200 bag emptier. The new ultrafine model can automatically empty even large bags containing very fine particles, including those that are extremely light and/or which pose a dust explosion or other type of hazard.
    The classic Dima® 200 is fitted with a dust-free handling unit, and bags can automatically be fed into the unit if desired. After the unit is sealed, the emptying process is automatically started whereby the bag, which is suspended by two hooks, is cut in half by a revolving knife. The emptying process is assisted via vibration, after which the empty bags are automatically discharged.

    Double filter with powerful suction and special air exhaust seal.
    The ultrafine Dima® 200 bag emptier was developed by Dinnissen especially for situations in which companies are required to prevent the release of even the smallest quantities of fine particles when bags need to be emptied. This newest version is fitted with a double filter with powerful suction and a special dust-tight seal for the air exhaust. The smoothly polished interior of the unit simplifies cleaning and prevents particles from being left behind in the machine. The design is based on Dinnissen’s easy-to-clean-concept which facilitates quick and efficient cleaning. Finally, the new model works with a fully automated cleaning-in-place concept based on air flow and suction, practically eliminating the need for any human intervention during the cleaning process.

    Automated cleaning of bags for improved hygiene
    In some situations, very strict standards apply in the area of hygiene and the prevention of contamination in the production process. Dinnissen Process Technology therefore also provides clients with an extra option whereby the bags, after being fed into the ultrafine Dima® 200, are first cleaned with the help of a special 'air knife' before being cut open. After the cleaning process, any dirt and contaminants present are first carefully sucked off and removed, and only then is the bag emptied.

    The new ultrafine Dima® 200 has a capacity of between 1 and 120 bags per hour and is presently being used in the feed, food, chemical and pharma sectors.

  • Innovative station for emptying big bags safely, hygienically, and residue-free

    Dinnissen Process Technology has developed an innovative station for emptying big bags of powders, particles and granulates safely and efficiently. The new system aims to provide a safe working environment for operators in a wide range of sectors. In addition, the big bag emptying station provides a clean, hygienic, and dust-free working environment.

    Dinnissen has developed an innovative system for emptying big bags safely in a particle-free environment for a wide range of users who process powders, particles or granulates that are supplied in big bags. The emptying station can empty up to 15 big bags per hour. The big bags are first placed on a special vibrating plate, after which the operator connects the transport hose and unties the bag. The system then stretches the bottom part of the bag. In combination with the special intermittent vibrating programme, this ensures that the big bag can be easily and efficiently emptied without any residue remaining behind. As the emptying process progresses, the bag is gradually stretched further to ensure that all of the powders, particles or granulates are emptied from the bag.

    The big bag emptying station can be equipped with extra functionality for companies who need to comply with additional requirements in terms of safety, hygiene and ease-of-use. During the emptying process, the big bag can, for example, be enclosed in a dustproof housing, whereby the big bags are completely emptied and rolled up compactly during the final phase of the emptying process. The emptying station can be fitted with a dustproof seal, special valves for removing unwanted contaminants, and an automated screen system that optimizes the safety and quality of the end product. A track and trace system can also automatically check on the contents of the incoming big bags and block the entry of additional bags if errors are discovered. If the aim is to further reduce the amount of manual labour required, the big bags can also be automatically fed into and removed from the emptying station. In addition, the emptying station can be fitted with a system that automatically picks up the big bag and removes the loop from which it is hanging at the end of the emptying process. Dinnissen also offers special tailor-made solutions for emptying very hazardous materials and emptying big bags without a transport hose connection.

  • New automated sampling system

    Consistent and accurate sampling delivers added value.

    Companies in the food, feed, pharma and chemical sectors which need to take reliable and accurate samples were until recently dependent uponmanual sampling, which is much more labour-intensive and generally less efficient and reliable than automated sampling. Dinnissen Process Technology has now developed a completely new and fully automated sampling system which complies with the most recent criteria of the EHEDG (European Hygienic Engineering & Design Group) and can be used for the automated sampling of incoming, stationary and outgoing product flows.

    Taking samples with the right frequency, volume and weight in continuous as well as batch production processes.
    Companies have to comply with increasingly rigorous requirements in the areas of safety and quality. The sampling of incoming flows of ingredients, intermediate products, and outgoing product flows is critical when it comes to determining microbiological or other quality parameters. The ability to sample these flows consistently, accurately and representatively greatly increases the value of the resulting information, which is why Dinnissen Process Technology has developed an automated sampling system that meets all these requirements. The system can be used for continuous as well as batch production processes based on dry powders, granules or granulates. All the user has to do is choose the desired parameters - such as frequency, volume and weight - beforehand, and the system automatically takes the required samples quickly, accurately and efficiently. The samples are collected in a laboratory beaker or sampling bag held in place by a quick-release tri-clamp fitting. Sampling capacity ranges from 25 g to 1000 g per sample, and the system can be integrated into new as well as existing production lines in a wide range of environments, including filling lines, silos, transport systems, mixing and packaging installations etc. The design allows the entire system to be easily, quickly and thoroughly cleaned, thereby eliminating the risk of contamination of the product or sampling flow.

    A practical and highly efficient solution for difficult situations.
    Dinnissen’s new and innovative automatic sampling system not only improves the reliability and accuracy of sampling processes, it also offers a much less labour-intensive solution when samples have to be taken in locations that are difficult to access, in continuous production processes, and in other difficult to manage situations.

  • Dinnissen introduces a worldwide first: unique automatic drum-emptier for toxic/explosive powdery products

    With personal protection and a safer workplace in mind, in mid-2015 an existing customer requested Dinnissen to think along about a solution for the automatic emptying of 200 dm³ drums containing toxic/explosive powdery products.

    The reason for this was that although the drums were already being emptied mechanically at the existing customer’s premises, the employees had to wear gas masks during the emptying of these drums, which is undesirable, especially for long periods of time.

    In the course of 2016, Dinnissen's specialists set to work and, in conjunction and regular consultation with the client, they developed a fully 3D-animated pre-engineering in order to present the first draft designs.

    Enthusiastic!
    The first draft designs were received with so much enthusiasm that by the end of 2016, Dinnissen was awarded the contract. This was the beginning of an exciting process of adaptations, improvements, unique innovations and frequent consultation with the client.

    Ready for the first test
    In early 2018, after more than a year of development, testing and improvement, the worldwide first of this truly unique automatic drum-emptier was a fact.
    The process starts with the supply of the closed drums, which are placed on the roller conveyor via the operator. After the 'release signal' and confirmation that the installation is ready, the drum is transported towards the first cabin.

    Opening of the drum: first part
    During the first operation, the lid is removed from the drum fully automatically with a special head piece, after which the lid remains clamped in this head piece. The drum is transported to the second cabin through an airlock. In the meantime, the clamped lid is pushed out of the head piece
    and placed on another conveyor belt. The lid that has just been removed is then transported to a separate cabin and cleaned with a neutral liquid, so after cleaning, it can be removed from the installation without any risk.

    Inliner: second part
    From the first cabin, and after removal of the lid, the drum now arrives in the second cabin. Because in some cases the drums are provided with a separate 'inliner' (a - usually - plastic lining on the inside of the drum) a provision had to be made to allow the operator to easily remove it. For this reason, the second cabin is provided with a special hatch that allows access not only to remove the inliner, but also to easily remove any powder residue. To further optimise accessibility and workability, the drum is positioned on a specially developed turntable, so the operator can work quickly and efficiently.


    Emptying the drum
    After the previous operation, the still filled drum is transported to the third cabin via another roller conveyor. Here the drum is fixed by a gripper arm, which rotates and empties the drum. At the express request of the client, this gripper arm is infinitely operable by the operator by means of a two-hand operation. This is a major advantage. After all, it allows the operator to look into the rotating drum and assess whether the use of a specially positioned 'beater' is necessary to knock any powder residues from the drum. In the meantime, possible powder chunks are reduced in size by a self-developed breaking knife.

    Both the inliner, if there is one, and the removed powder continue their way via the roller conveyor, with the inliner being automatically transported to the shredder and shredded. Because these flakes may still be contaminated with the toxic/explosive residual product, they are stored in a special container that is eventually filled with a cleaning liquid. After a certain time, this liquid is drained and the flakes can be repacked and safely disposed of.

    Last step: cleaning the drum
    After emptying, the drum is returned to the starting position with the same two-handed operation and transported to the cleaning cabin via the roller conveyor. Here the drum is fully automatically clamped, lifted, turned over, brought into the desired cleaning position and rinsed out with a large amount of liquid, then blown dry with compressed air and placed back on the roller conveyor, after which the clean drum is fully automatically released via a secured hatch.

    Additional safety
    For the sake of additional safety, each cabin is regarded as an isolated space, which can be locked securely by its own automatic doors or shutters. If required, the operator can inject nitrogen into any cabin containing potentially explosive products, eliminating the chance of a possible explosion. The installation is also equipped with a built-in air dryer, including filters that prevent vapours from spreading through the installation. Another equally innovative measure is the constant negative pressure, which ensures no toxic/explosive vapours can escape when the drums are introduced or released.

    Naturally, the complete electronic control and monitoring, including visualisations, have been developed and implemented by Dinnissen. All in all, this is a technical tour de force which will be highly regarded worldwide.
