Manufacturers of meals and other hygienically processed products face the problem of sustaining reproducible processes so that their merchandise have the looks, style, and consistency that buyers anticipate.
GEA has designed the VARIVENT MX with components that hold merchandise from mixing with the cleaning liquid, even beneath exceptional loads. The cavity chamber is fitted with a vacuum self-drainage system and balancers on each valve discs. For most physical security, GEA makes use of the Venturi effect which is created by the particular form of the move channels, inflicting a vacuum on the other seal throughout lifting, preventing pressure will increase. As เกจวัดแรงลม , no cleansing liquid can enter the opposite pipe carrying the product whereas 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 time, there’s a higher danger of overpressure throughout operation. The valve discs must stay in place when water hammer occurs, and the valve should remain closed. For this objective, GEA has geared up the valve discs in each pipelines with balancers – strain compensators. This makes the closed valve proof against water hammer as much as 50 bar within the upper and lower pipelines. The new MX valve type additionally has an integrated balancer cleaning device. It ensures that the balancer is totally flushed from the surface during seat lifting simultaneously cleaning-in-place is happening. All surfaces in contact with the product could be cleaned without any additional elements defending the product from contamination.
