Zanin - Model PSC 5 - Sieve grain cleaner-separator and grader
From Grain/seed cleaning
Two phase cleaning system. The product with impurities enters by way of gravity. The counterweight system allows uniform distribution of the product which encounters a cross air flow to removes lighter particles. It then enters the sieve case which contains the perforated screens installed to suit the particular treatment. The upper sieve divides the product from large impurities, the lower sieve divides the desired product from fine impurities. The same process then takes place in the lower sieve case. Before exiting the cleaner, the product is passed through a rate reduction system where an air flow removes lighter particles. These are sent to a cyclone or alternatively to a filter.
