Pre-cleaning of grain by weight and size

Pre-cleaning of grain by weight and size

To remove more heavy impurities in the grain, it is necessary to use a screen cleaning process, also for the pre cleaning. During the first passage on the screens, large impurities (oversize) are held back and separated from the grain. During the second stage, the good kernels are held back, and the small seeds and the heavy sand are removed from the good quality grain. 

After having been processed on the screens, the grain passes through an aspirator cleaner section, which evacuates the remaining content of dust and light particles in the good grain.

The impurities and screenings are conveyed through pipes to be delivered through a cyclone into a storage facility, i.e. a trailer.
