Dinnissen Process Technology introduces brand new concept Dinnissen Process Technology presented its Magi-‐N.ext, a brand new extruder line concept for the feed and (pet)food industry. With Magi-‐N.ext, Dinnissen is targeting feed and (pet)food producers who wish to use a single production line for producing economic/basic, premium and super-‐premium feed and (pet)food. The Magi-‐N.ext enables these producers to do so in a customer-‐focused and cost-‐ effective manner, while at the same time complying precisely with their desired quality and hygiene standards within a multi-‐flexible framework. Fast and efficient changeover to new products and recipes

Before ingredients are allowed to enter the extruder, they are brought into suspension by the rotating fins of Dinnissen’s CZ Sifter, making it possible to quickly and efficiently monitor the quality of even the very finest micro-components (800-1000 microns). This also prevents metallic or other hard particles from damaging the extruder and interfering with the production process. The Magi-N.ext reduces energy consumption primarily by recovering heat from the extruder’s outflow of air and using gravity as an important driver for transport. In addition, the precision of the production method, which ensures that the product is never heated or treated any longer than necessary, also results in significant energy savings. Quality and safety at the very highest level The application of gravimetric dosage in combination with automated weighing in the conditioner provides users of the Magi-N.ext with a unique method for automatically maintaining optimum product residence time (1 to 4 minutes) in the conditioner. As a result, producers can control and maintain a very constant quality level. Not only can recipes be executed automatically and precisely, but specifications regarding pre-treatment and safety can also be complied with very precisely by maintaining the correct residence time in the conditioner. Dinnissen Process Technology has also introduced a very innovative method for premixing pigment just before the extruder. This method allows the user to add pigments very precisely and homogeneously via a continuous dosage system. The formation of lumps or undesirable colours in the extruder is now a thing of the past, and producers can now be assured of uniform colour results. Finally, the continual removal of moisture and vapour throughout the entire production process helps to ensure that the end product

complies with the strictest standards of hygiene. Maximum opportunity for working extremely precisely and homogeneously Within the framework of its new Magi-N.ext concept, Dinnissen is also applying its famous Pegasus® vacuum core coater concept. This coater allows for the weighing and dosing of precise amounts of fat, liquid and powdered flavour enhancers, vitamins, enzymes and other additives as well as the exact control of various production variables such as temperature, pellet mixing speed, and product residence time. The end result: an extremely precise and homogeneous distribution of the ingredients throughout the pellet with a great many possibilities for varying the process at will. Last but not least, the application of Dinnissen’s well-known Pirouette® Dryer contributes to obtaining optimum results in the area of quality and hygiene. This dryer, fully equipped with PLC controls, allows the user to achieve extremely homogeneous end results and prevent contamination. The Pirouette® Dryer is also suitable for drying pellets in a size range of 2–22 mm in various temperature zones, thereby enhancing the flexibility of the Magi-N.ext even further. More information on the Magi-N.ext Additional information about the Magi-N.ext is available from Dinnissen Process Technology in Sevenum (Tel: +31 77 4673555). Dinnissen provides consulting services to feed and (pet)food producers, designs, manufactures and installs complete feed and (pet)food production lines and renovates existing production processes.
