This machine sorts the grains based on two parameters, weight and shape

In the first stage, the seeds are exposed to air suction, which leads to the separation of lighter wastes such as straw, dust, peel of seeds, hollows of seeds, herbs, thorns and others from the original seeds. In the second stage, the seeds enter two distinct sieve tanks, which are included in parallel. In both sieves, the grains are separated according to size, then the grains of each of the two tanks are combined, and once again the grains are exposed to air suction for uniformity. Replacement sieves allow users to separate all types of seeds.
