Dairy Show 2015 - Hygienic material handling equipment for the dairy industry

International Dairy Show 2015 - Coperion and Coperion K-Tron present components in sanitary design

At this year’s International Dairy Show, Coperion and Coperion K-Tron will exhibit in booth 8355 at McCormick Place, Chicago, IL. Guests of the booth will see a WYK Two-Way Diverter Valve, a ZRD Hygienic Rotary Valve and a P30 Sanitary Vacuum Sequencing Central Receiver.

Coperion and Coperion K-Tron are proud to be finalists in food safety and packaging categories for the International Dairy Association’s Innovations Award. The WYK Diverter Valve, known for its innovative design, has been nominated for its substantial achievements in performance and having shown significant advancement in its application.

WYK Two-Way Diverter Valve
The WYK Two-Way Diverter Valve is ideally suited for inline material handling of hygienic and difficult to handle powders, such as whey powder, lactose, dried milk powders and infant formula. This valve can be used in pneumatic conveying systems, in order to divert transfer of the powder to different locations. The fully automatic CIP cleaning design permits complete purging of all product residues after the automatic cleaning process. Due to a unique retractable rotor assembly, the rotor can be pulled slightly out of the housing towards the rear of the valve, thus allowing the cleaning solution to rinse all product contact surfaces within the valve. In addition, specialty purge openings in the actuator plate enable an intense rinsing flow and complete discharge of the rinsing effluent.

Beside the WYK Two-Way Diverter Valve we will exhibit a hygienic ZRD Rotary Valve and a P30 Vacuum Sequencing Central Receiver for sanitary pneumatic conveying.

We look forward to welcoming you at the International Dairy Show 2015!

Spray Drying Process for Dairy Powders and Infant/Baby Formulas

Use of Innovative and Sanitary Coperion Valves in the Spray Drying Process for Dairy Powders and Infant/Baby Formulas

The production of dry dairy powders and infant/baby formulas requires extremely sanitary design of the equipment. The system provided must handle a wide variety of difficult flowing and temperature-sensitive ingredients, including vitamins, nutrient additives and even probiotics. In addition, dependent upon the type of process and the processing environment, the equipment must be able to be cleaned by either dry or wet cleaning methods. Coperion pneumatic conveying systems and material handling components are utilized for the transfer of the raw ingredients as well as the final blended/spray dried product prior to packaging. The pneumatic conveying systems include both positive pressure and vacuum, dilute and dense phase.

Powdered infant formula is generally manufactured via dry blending or wet blending with subsequent spray drying. In the spray drying process the pasteurized and homogenized liquid is atomized in the spray dryer chamber. Water is evaporated and then dry powder deposits on the spray dryer bottom, where it is discharged with a sanitary Coperion rotary valve to a fluidized bed. There the product is typically dried further, cooled, sifted and then pneumatically conveyed to storage silos or packaging lines. The outlet air from the spray drying chamber still carries product (fines) which is normally ducted into cyclones and bag filters. From there the product is discharged with sanitary Coperion rotary valves into the fines return line. The fines can either be transported with pneumatic conveying to the fluidized bed or back to the top of the spray dryer for agglomeration purposes. The actual conveying path is selected by the sanitary Coperion WYK diverter valve. Moisture and warm temperatures are conducive to bacterial growth, therefore wet cleaning is normally applied in this process while dry cleaning is often typical in the process after the fluid bed dryer.

The wet cleaning process can require extensive resources. Time and costs can be saved if the washing process can be automated (clean-in-place or CIP). For the past years Coperion has been delivering special components that can be cleaned in the process without need for dismantling. This also reduces the risk of external contamination in the process. Coperion rotary valves are designed such that the rotor stays in the housing and discharges the washing liquids by rotating. Retention-free design including special CIP-gaskets at the inlet and outlet as well at the sideplates assure that no product or liquid remains anywhere. Tests at authorized institutes (EHEDG) have proven that the components are absolutely clean. As an added benefit for food safety, Coperion rotary valves can also be equipped with the innovative Rotorcheck design option, which can detect metal to metal contact between the rotating blades and valve housing, as a function of electrical resistance between the rotating vanes and housing.

The stainless steel WYK diverter valve was specifically designed on the basis of the guidelines of the EHEDG for CIP cleaning of the fines return line or other powder conveying pipes. The conical rotor is switched between conveying tubes via actuator while the diverter is operated in conveying mode. During CIP cleaning the rotor is extracted slightly by a second actuator which allows the cleaning liquid to reach all areas of the inside while the diverter is still closed to the outside. The diverter valve, often installed at positions with limited access, does not need to be opened during or after CIP and yet is thoroughly clean afterwards, which saves time and costs. Today, the WYK is in operation in many dairy and infant formula plants and has become a standard wherever highest hygienic requirements must be fulfilled.

International FoodTec Award in Gold for High Moisture Extrusion Solution

Innovative equipment concept for production of meat substitutes

Diagram of an extruded pellet with micro-incapsulated particle/drops
Award-winning plant concept for high moisture extrusion

Coperion has already been working closely with the German Institute for Food Technology (DIL) in Quakenbrueck/Germany for some time. The spotlight at this year's Anuga FoodTec 2015, the trade fair for the international food and beverage industry, also focused on our ZSK twin-screw extruder, which is fitted with a cooling nozzle from the DIL for producing meat analogues. This equipment concept developed at the German Institute for Food Technology (DIL e.V.) for producing meat analogues products for the DLG (German Agricultural Society e.V.) has now been presented with the International FoodTec Award in Gold.

Just nine innovations obtained the International FoodTec Award in Gold. The award ceremony took place in Cologne/Germany on 24 March 2015 a festive setting at Anuga FoodTec.

The concept is based on the combination of the feeder, extruder, cooling nozzle, and cutting device units. This is a very sensitive process, for which the equipment configuration and process parameters must be precisely aligned to the feed stocks and the targeted end products. The challenge lay in the development of a concept that facilitated this alignment and permitted the production of different textures, which correspond to beef, pork, poultry, or meat structures. At the same time, it had to be possible to process different raw materials (soy, pea, and lupine protein), as the production equipment available so far has its limits precisely in this area, and can only be used for the production of an individual product.

The International FoodTec Gold Award was triggering new interesting and forward-looking projects in the field of textured vegetable proteins, which is the base for more diverse vegan and vegetarian products. In collaboration between Coperion and the German Institute of Food Technologies (DIL) corresponding concepts will be developed for the customer currently.
