Manufacturers of food and other hygienically processed merchandise face the problem of sustaining reproducible processes so that their products have the looks, taste, and consistency that buyers anticipate.
GEA has designed the VARIVENT MX with components that keep products from mixing with the cleaning liquid, even under distinctive masses. The cavity chamber is fitted with a vacuum self-drainage system and balancers on both valve discs. For most bodily security, GEA makes use of the Venturi effect which is created by the special shape of the move channels, causing a vacuum on the alternative seal throughout lifting, preventing pressure increases. As a end result, no cleaning liquid can enter the other pipe carrying the product whereas a valve seat is being lifted or cleaned, even if a seal is flawed.
When pressure gauge are set up and adjusted in a quick while, there is a greater danger of overpressure during operation. The valve discs must stay in place when water hammer happens, and the valve must remain closed. For this purpose, GEA has geared up the valve discs in each pipelines with balancers – strain compensators. เกจวัดแรงดันpressuregauge makes the closed valve resistant to water hammer up to 50 bar within the upper and lower pipelines. The new MX valve type also has an built-in balancer cleansing device. It ensures that the balancer is totally flushed from the outside during seat lifting concurrently cleaning-in-place is happening. All surfaces involved with the product can be cleaned without any extra parts protecting the product from contamination.
