Abstract

The invention concerns a method comprising the fol­ lowing steps:
a) a first step of wheat accumulation and dwell;
b) a step of layering the wheat over a first vibrating screen having smaller size holes than the wheat size and being swept by an ascending air stream;
c) a step of separating the heavy wheat fraction by passing through a second vibrating screen having larger size holes than the wheat size and being swept by an as­ cending air stream;
d) a second step of wheat light fraction accumulation and dwell which did not go through said vibrating screen during step (c); and
e) a step of dropping the wheat from step (d), said dropping being in the form of a thin layer and in coun­ tercurrent with respect to an ascending air stream;
and a device comprising a loading well, two vibrating screens, a discharge well, and a suction channel.
The invention affords large power savings and con­ siderable reduction of the whole wheat cleaning system vertical height.
