Anotations

Scope note:

The grain cleaner thus removes all minerals (e.g. sand, clods of earth, stones), pieces of glass and metal. In addition, it eliminates organic impurities such as straw, hulls, stalks, husks, weeds and even their seeds. Besides, the machines presented by us are able to separate infected material already in pre-treatment.
