Manufacturers of meals and other hygienically processed merchandise face the challenge of maintaining reproducible processes in order that their products have the looks, taste, and consistency that buyers anticipate.
GEA has designed the VARIVENT MX with parts that maintain products from mixing with the cleansing liquid, even under exceptional masses. The cavity chamber is fitted with a vacuum self-drainage system and balancers on both valve discs. For maximum physical security, GEA makes use of the Venturi effect which is created by the special shape of the flow channels, inflicting a vacuum on the other seal during lifting, stopping stress increases. As a result, no cleaning liquid can enter the alternative pipe carrying the product whereas a valve seat is being lifted or cleaned, even if a seal is defective.
When new systems are set up and adjusted in a short time, there’s a higher risk of overpressure throughout operation. The valve discs must keep in place when water hammer happens, and the valve must remain closed. For this purpose, GEA has geared up the valve discs in both pipelines with balancers – pressure compensators. This makes the closed valve resistant to water hammer as a lot as 50 bar in the upper and decrease pipelines. The new MX valve kind additionally has an built-in balancer cleaning device. It ensures that the balancer is completely flushed from the skin throughout seat lifting at the same time as cleaning-in-place is happening. All surfaces in contact with the product could be cleaned with none further components defending the product from contamination.
