Manufacturers of food and other hygienically processed products face the challenge of maintaining reproducible processes in order that their products have the looks, taste, and consistency that consumers anticipate.
GEA has designed the VARIVENT MX with elements that keep products from mixing with the cleansing liquid, even beneath distinctive masses. The cavity chamber is fitted with a vacuum self-drainage system and balancers on each valve discs. For maximum bodily safety, GEA makes use of the Venturi effect which is created by the particular form of the move channels, causing a vacuum on the opposite seal throughout lifting, stopping stress 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 when a seal is defective.
When new systems are arrange and adjusted in a brief while, there’s a higher risk of overpressure during operation. เกจวัดแรงดัน must stay in place when water hammer happens, and the valve should stay closed. For this purpose, GEA has equipped the valve discs in both pipelines with balancers – strain compensators. This makes the closed valve proof against water hammer as much as 50 bar in the upper and decrease pipelines. The new MX valve kind additionally has an built-in balancer cleansing device. It ensures that the balancer is completely flushed from the surface during seat lifting concurrently cleaning-in-place is taking place. All surfaces involved with the product may be cleaned without any extra components protecting the product from contamination.
