The separation of seeds from the heap is effected thanks to the vibration of the flat sieves. The efficiency of the cleaning process of the sieves from the cleaning system depends on the following factors: the inclination of the sieves, the sieves size and mainly of the character of the relative movements of the seeds on the sieve, respectively the cinematic regime of the sieves. For the experimental tests, it was used the selector of the seed cleaning machine, where the supply discharge and sieve inclination angle were modified.
