FIELD: agricultural engineering. SUBSTANCE: method of seed cleaning according to physical and mechanical properties of seeds comes to delivering initial mixture to sieve pan rigidly secured on vibrating friction flat deck, primary separating on sieve pan, separating of mixture on vibrating friction surface of deck and dividing mixture into fractions by rotating conveyer installed above deck. Rotating conveyor has gripping members - flexible threads acting in direction nonparallel to direction of movement of mixture after which remnants are exposed to action of air stream from air column whose inlet nozzle is mated with fraction remnants receiver.
