Manufacturers of food and different hygienically processed merchandise face the problem of sustaining reproducible processes so that their merchandise have the looks, taste, and consistency that buyers anticipate.
เพรสเชอร์เกจ has designed the VARIVENT MX with elements that maintain products from mixing with the cleaning liquid, even underneath distinctive masses. The cavity chamber is fitted with a vacuum self-drainage system and balancers on each valve discs. For maximum physical safety, GEA makes use of the Venturi impact which is created by the special form of the flow channels, inflicting a vacuum on the alternative seal during lifting, preventing strain increases. As a outcome, no cleansing liquid can enter the opposite pipe carrying the product whereas a valve seat is being lifted or cleaned, even when a seal is defective.
When new techniques are set up and adjusted in a quick time, there is a greater danger of overpressure throughout operation. The valve discs must stay in place when water hammer occurs, and the valve must stay closed. For this function, GEA has geared up the valve discs in each pipelines with balancers – pressure compensators. This makes the closed valve immune to water hammer as much as 50 bar within the higher and lower pipelines. The new MX valve kind additionally has an integrated balancer cleansing device. It ensures that the balancer is totally flushed from the surface during seat lifting concurrently cleaning-in-place is going down. All surfaces in contact with the product may be cleaned without any further components protecting the product from contamination.
