SEPARATOR FOR THE LOOSE CROPS Russian patent published in 2007 - IPC B07B4/00 

FIELD: mechanical engineering; agriculture; production of the devices for separation of the cereals and the groats.

SUBSTANCE: the invention is pertaining to the pneumatic separators for the loose stocks, in particular, to the cereals and the groats used for separation from the grain heap of the valuable aligned seeds of the heightened biological value and the milling fraction at the flour mills, shelling of the groats raw and sorting of the groats. The separator of the loose crops, in particular, the grains and the cereal products includes: the distributor of the cereals along the blowing chamber widthwise; the horizontal blowing chamber with the shutters at the inlet and the outlet; the dividing chamber partitioned lengthwise by the relocatable partitions, the located under the blowing chamber valve boxes and the valves of discharge of the accumulated above them product. The grain distributor is sealed against the air penetration from the environment. The walls of the blowing chamber are made plane without the ribs the air turbulence. The grain is fed into the blowing chamber from the distance up to the vertical wall of 1-1.5 cm. The valves are made in the form of the pipes made out of the elastic material and are closing under action of the rarefaction in the blowing chamber and are opening under action of the mass of the product. The technical result of the invention is improvement of the quality of separation of the loose crops into the desirable quantity of the fractions.

EFFECT: the invention ensures the improved quality of separation of the loose crops into the desirable quantity of the fractions.
