DEVICE FOR SEPARATING PLUMULACEOUS FEATHER MATERIAL INTO FRACTIONS Russian patent published in 2011 - IPC D01B3/00 B07B9/00 B68G3/02 

FIELD: chemistry.

SUBSTANCE: device has a housing with a hatch for loading material and an agitator, a ventilator for generating a sorting air stream, two chambers, walls and movable partitions which form a vertical labyrinth. The first chamber is equipped with a discharge chute with an outlet, a filter and an agitator, and the second chamber is equipped with a belt conveyor with a guide comb and a modifying roller with a toothed incision and a discharge chute with a socket piece, a filter and an agitator. In the second chamber, the guide comb and the modifying roller with a toothed incision are combined into a unit which is fitted with a displacement mechanism for measuring its position relative the belt conveyor, and there is a hatch for isolation for the discharge chute. The first chamber has an additional discharge chute with a filter and a socket piece and a modifying unit formed by two pairs of rollers, wherein one pair has a flat surface and the other has a toothed incision.

EFFECT: broader functionalities of sorting equipment by combining in one device, processes for separating into fractions feather material of natatorial and land birds and modification of fractions in order to improve quality characteristics of the desired fraction.
