Duck Type Aspiration Channel

The aspiration channel is a high-throughput cleaning machine. It cleans lighter impurities from grain and separates them by weight. You can use it for many grains and pulses, including common wheat, durum, corn, rye, soybeans, oats and cocoa beans.The clean product is fed into a cylindrical rotary drum covered with interchangeable screens. The first screen removes fine impurities (sand, broken grain, etc.), the subsequent screens allow the clean product to pass through the perforations, and larger impurities at the end of the drum.Aspiration.
