Hygienic Design Feeders, Components and Conveying Systems for Sanitary Applications
The production of dry dairy powders and infant/baby formulas requires extremely sanitary design of the equipment as well as high accuracy in the precise addition of ingredients to the formula blend. The system provided must also offer the versatility to handle a wide variety of difficult flowing and temperature-sensitive ingredients, including vitamins, nutrient additives and even probiotics. In addition, depending upon the type of process and the processing environment, the equipment must be able to be cleaned by either wet or dry cleaning methods. The hygienic designs provided by Coperion and Coperion K-Tron are easily adaptable for all of these requirements.
Products and ingredients may include: milk powder, whey powder, lactose, casein, cheese powder, infant formula, maltodextrine, probiotics, vitamins, baby food
- Global systems engineering group with extensive application experience for the entire milk powder processing line ensures optimal design with an emphasis on product safety, quick product changeover and increased efficiency
- Highest sanitary design according to the current guidelines and regulations
- Innovative, custom engineered Coperion rotary and diverter valves ensure reliable, long-term and safe operation
- Equipment and system designs in accordance with a wide variety of regulatory standards
- Coperion is an active member of the European Hygienic Engineering and Design Group (EHEDG) and therefore the latest developments and directives are directly incorporated into design of all components
- Coperion K-Tron line of feeders provides maximum accuracy for adding high value ingredients like vitamins and probiotics
- Extensive material handling expertise for even the most difficult flowing dairy powders like lactose and maltodextrin
Comprehensive Product Range
UNSURPASSED WEIGHING TECHNOLOGY FOR THE HIGHEST ACCURACY INGREDIENT ADDITION
Coperion K-Tron feeders provide the highest accuracy for both batch and continuous blending operations, at rates as low as 50 g/h! Both loss-in-weight and gain-in-weight batching techniques are available, depending upon the accuracy required. High value ingredients such as probiotics can be safely and precisely added to the formulation in accordance with the application recipe. In addition, multi-feeder operations can accurately dispense each of the components to the blender, assuring a safe and efficient automated blending operation.
Volumetric and gravimetric feeders
Hygienic Components for Safe and Efficient Transfer
Whether dry blending or using a spray drying process, Coperion components such as rotary and diverter valves provide the highest degree of hygienic design. Components are available in both EHEDG and USDA certified designs and provide durable and reliable operation for the dairy powder process. Coperion offers 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 hygienic rotary valves are designed such that the rotor stays in the housing during CIP 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.

Sanitary Systems Design for Material Transfer
In both the wet and dry blending processes for dairy powder and infant formula manufacture, Coperion and Coperion K-Tron pneumatic conveying systems and material handling components are utilized for the transfer of the raw ingredients prior to blending as well as transfer of the final blended/spray dried product prior to packaging. The conveying systems provided by Coperion K-Tron include both positive pressure and vacuum, dilute and dense phase and are designed with the highest sanitary standards with options for wet or dry clean operations.

Frequently Asked Questions
What are differences between Cleaning-Out-of-Place (COP) and Cleaning-in-Place (CIP) when it comes to rotary valve and diverter valve design?
Extremely stringent hygienic and purity requirements are very important when processing dairy powders. It is often necessary to clean and inspect production systems regularly in order to meet the increasingly stringent specifications of the dairy and infant formula industries. Wet cleaning is recommended when the product is perishable or products are changed frequently. Milk powder and baby food are typical examples of products in which dry cleaning is often no longer sufficient. The inside of hoppers, conveying pipes and bulk materials components are cleaned according to a specified procedure with cleaning media, such as weak acids or lyes and water. For this reason it is imperative that all equipment in the production process can withstand the cleaning media.
There are two different cleaning methods used in the industry
- Cleaning-Out-of-Place (COP)
- Cleaning-in-Place (CIP)
Download our technical paper on CIP/COP for more information on each of these cleaning operations and how the design of the components is critical based upon the cleaning method. It discusses the design differences in detail of both rotary and diverter valves for each of these cleaning methods.
