Coperion, Stuttgart, Germany, introduced a blow-through valve type ZXD in Hygienic PLUS execution to be certified in compliance with the criteria of the European Hygienic Engineering & Design Group (EHEDG), type ED at Interpack 2014.
With the new blow-through valves type ZXD and the discharge valves type ZRD Coperion now offers the food industry the first rotary valves in the world in Hygienic PLUS execution. The EHEDG, type ED criteria formulate the requirements to be met by components that are used in systems with dry operation and dry cleaning processes. Important features of the certified Hygienic PLUS rotary valves are that they are easy to dismantle and that the component areas can be easily accessed for cleaning and inspection. The surfaces are smooth and the interfaces to the areas in contact with the product are step-free.
Coperion was already a pioneer in the development of CIP-compliant (Cleaning in Place), certified rotary valves and diverter valves that are cleaned with liquids. With the new EHEDG type ED-certified rotary valves the company now also supplies dry cleaning components to assist system integrators and end users who must reliably satisfy high requirements when it comes to sanitary design and operational safety in the food industry during the production, processing and transport of powders and pellets.
