Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention provides a rotary grain sorting device that sorts grains supplied into the interior of the sorting tube by rotating a sorting tube having a recessed portion on the inner peripheral surface. Regarding the rice hulling machine.

Problems to be Solved by the Invention The grains are husked by a husking device, and the scraped rice is scooped out by forming a recess on the inner circumferential surface and scooping it up in the center. In a huller that feeds and sorts grain into a rotating grain sorting cylinder equipped with a receiving gutter that receives and carries out the grain, the rice grains that have been scraped out from the hulling device are placed on the lower side. A method is used in which the waste is air-selected in a wind-selecting room, etc., and then conveyed to the rear upper part of the dehulling device using a thrower, etc., and then fed to a rotating sorting cylinder. In order to improve the sorting throughput, the height of the machine becomes higher.
