Abstract

PURPOSE:To enable rice polishing by placing a husking part on the upper part of one side of an air sorting machine and alternatively placing a sorting mechanism and a rice milling mechanism on the upper part of the other side of the air sorting machine. CONSTITUTION:When unhulled rice is fed to the paddy hopper 2 of a husking part 1 and the respective rotary parts of a rice husker are driven, unhulled rice fed to the husking rolls 3, 3 from the paddy hopper 2 receives husking action and rice without winnower is air-sorted in the lower air-sorting path 4. Air-sorted husk is discharged to the outside of the machine through a dust discharge cylinder 6 and mixed rice of unpolished rice and unhulled rice falls and is fed to a receiving gutter 7. This mixed rice is elevated to a mixed rice hopper 9 by a grain elevator 8 and introduced into the initial end part of a feed gutter 14 of a rotary sorting cylinder 11 side and fed to the end part of the feed side of the cylinder 11. Then this mixed rice if sorted while being dipped by the recessed holes of the cylinder 11. Thereby degree of freedom of unpolished rice takeout operation can be extended.
