APPARATUS FOR SEPARATING GRAIN PRODUCTS Russian patent published in 1994 - IPC

FIELD: agroindustrial complex in grain procession industry branches. SUBSTANCE: apparatus has the annular sorting deck 1, on a middle portion of which a grain mixture is being continuously fed. The deck 1 performs rotary oscillations around a vertical axis. The radial corrugations 2 and the outer and the inner annular thresholds 3, 4 respectively are made on the deck 1. The threshold 3 has convex openings in its lower portion. The corrugations 2 are mounted with a gap between ends of the corrugations 2 and the threshold 3. The threshold 4 has portions of large height in places of feeding an initial material. More dense and more small particles are being immersed into lower beds and are being discharged through openings of the threshold 3. The large size and less dense particles are floated, and they are being removed from the deck through low-level portions of the threshold 4. EFFECT: enhanced quality of separation. 3 cl, 2 dwg
