FIELD: food industry.SUBSTANCE: machine contains a cylindrical body equipped with a helical guide and installed so that to enable rotation, a perforated rotor (installed inside the body and equipped with a receiving helical appliance designed in the form of a hollow perforated conic multiturn helical jacket), a water delivery unit, a feeding and a discharging appliances. The rotor is mounted on at least one of the perforated strips that are wound into helical coils and interconnected via their longitudinal edges; the strip is bend along the bending lines positioned at an angle relative to its longitudinal edges so that to form unidirectional helical lines and helical surfaces in the form of perforated polygonal pockets across the outer and the inner surface. The distance between the bending lines is equal to the length of each element of the polygon. The perforated pockets on the inner surface may differ from those on the outer surface in terms of shape and size and may be differently shaped along the perimeter.EFFECT: invention usage allows to enhance seed separation efficiency.7 dwg |
