FIELD: process engineering.SUBSTANCE: invention may be used in agriculture for seed cleaning. Proposed device comprises loading-unloading station, annular proportioner and conical feeder arranged on guide, and working member stages arranged one above the other to displace in height and be fixed at definite positions. Every said stage comprises reflecting element shaped to truncated cone with larger base directed downward, separator composed of cylindrical surface aligned with cone, and funnel-shaped grain board with convex slot. Funnel-shape feeder is arranged on retainer. Grain board is equipped with annular proportioner and doubles as loading-unloading station. Every stage comprises said feeder, reflecting element, separator and loading-unloading station with annular proportioner.EFFECT: higher quality and efficiency.1 dwg |
