GRAIN MIXTURE SEPARATING METHOD Russian patent published in 2003 - IPC

FIELD: agriculture, in particular, cleaning of grain mixtures from contaminant particles differing in length. SUBSTANCE: method involves separating grain mixture by means of vibrating endless screens with round openings; applying electrostatic field; feeding grain mixture in single layer onto endless screen longitudinally vibrating in horizontal plane at frequency of 350-500 vib/min and amplitude of 0.1-1.0 cm at electrostatic field intensity of 5-15 kV/cm. EFFECT: increased quality of grain mixture separation. 1 tbl
