The aspiration channel is used in grain cleaning applications for separating specifically lighter particles from granular products. Its field of application extends across different grain varieties such as groundnut, wheat, Rice, coriander, cumin, mustard, Chickpea etc. Optimal separation for producing clean grain.

On the basis of selective air flow control, the stream of product is distributed regularly across the entire machine width, caught by the aspiration air flowing through, and separated according to specific gravity. This produces an optimal separating efficiency of the specifically lighter particles such as straw, dust, or hull fragments.

To enable better checking of adjust-ments, the aspiration channel is equipped with a large transparent partition, which in addition is illuminated. This allows the process to be carefully observed, and the separating efficiency can be quickly adjusted at any time to the product to be aspirated.
