Operating principle
The product flows by gravity into the electric distributor and occupies the entire width of the machine. Then the grain descends lower and an air stream passes through it, blowing out light impurities.
Then the product enters a rotating drum, which is equipped with interchangeable sieves. Small impurities go through the first sieve, then a good product comes out and large impurities come out at the end of the drum.
The size of the holes in the sieves is selected depending on the type of product to be cleaned.
