Manufacturers of meals and different hygienically processed merchandise face the problem of maintaining reproducible processes so that their products have the appearance, style, and consistency that customers count on.
GEA has designed the VARIVENT MX with elements that hold merchandise 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 impact which is created by the particular form of the flow channels, inflicting a vacuum on the other seal throughout lifting, preventing stress increases. As a result, no cleaning liquid can enter the alternative pipe carrying the product while a valve seat is being lifted or cleaned, even if a seal is defective.
When new techniques are set up and adjusted in a brief while, there is a greater threat of overpressure throughout operation. The valve discs must stay in place when water hammer happens, and the valve should remain closed. For this objective, GEA has equipped the valve discs in both pipelines with balancers – stress compensators. This makes the closed valve resistant to water hammer up to 50 bar within the higher and lower pipelines. The new MX valve kind additionally has an built-in balancer cleansing device. It ensures that the balancer is completely flushed from the outside throughout seat lifting concurrently cleaning-in-place is taking place. All surfaces in touch with the product may be cleaned without any additional elements protecting the product from contamination.
