Seed / Grain Cleaning Machine

The primary method of seed cleaning is the air-screen separator. It uses a combination of air, gravity, and screens to separate seed based on size, shape, and density. These widely-use units come in a variety of models with two to eight vibrating screens. In all cases, the cleaning principles are the same. The grains are fed into the hopper where they are evenly distributed by a feed roller and transferred through a controlled gate on the top sieve. In the process the grains are subjected to primary aspiration by the use of air trunk which drains off chaff, straw, dust or deceased grains. Then the material is passed through sieve layer for separation according to their width and thickness. After the separation, the graded material is subjected to air sifter and aspiration chamber where remaining light particles are sucked off by a strong upward draught of air. The graded material and the impurities are automatically discharged in separate chutes.

Designed with precision, these machines are suitable for efficient cleaning of all cereal grains, pulses and seeds of different crop including wheat, paddy, barley, maize, millets, sunflower and more. This machine uses the principle of screening and airflow to remove the unwanted material from the grain. Easy to operate, the speed of the machines can be adjusted for the desired result.
