The product is uniformly fed into the unit as a thin layer by a vibratory feeder. Then the light particles and impurities are removed with the vacuum effect of airflow created by axial fans; and they leave the unit on a screw-type discharge conveyor.
The machine has a low air requirement with the recycling design. In this system, 80% of used air is feeded back to the system, and only 20% of fresh air is required to stabilize the interior pressure.
Product feeding system alternatives by use purposes are;
• For the usage with a scourer, the machine has a vibrating product inlet system which is driven by two vibro motors.
• For the usage with grain separator, it has a product feeding regulation mechanism that can be integrated with the outlet of grain separator.
