Three-Deck Precision Cleaning Machine This machine is designed for cleaning dry granular agricultural products such as legumes, cereals, and especially seeds, separating organic and inorganic foreign materials. The machine works by: -Separating light particles and weak products through the vacuum chamber. -Sorting fine and small particles from the product using a sieve (under-sieve). -Separating coarse and large particles using a second sieve (over-sieve). The product that has undergone preliminary cleaning can be classified into two sizes at the final sieve. Depending on the sieve selection, the product that has gone through preliminary cleaning can also undergo sizing, with a maximum of four sizes, or for precision cleaning after the cleaning process, two sizes can be obtained.
