PROBLEM TO BE SOLVED: To improve the precision of mixed rice separation. SOLUTION: A rotational separating cylinder whose inner surface is provided with many drawing vanes is laterally hung on a mixed rice separating part of this husking separator, a grain screen separating device is obliquely disposed on the upper part of a gutter for receiving unpolished rice which is arranged in the rotational separating cylinder and a gutter for supplying mixed rice and the mixed rice which is drawn by the drawing vanes is supplied plural times to the grain screen separating device and, thereby, is separated to hulls and unpolished rice. The separation initiating side of the grain screen separating device is made rather coarse, the separation terminating side is made rather fine and a foreign matter recovering part is disposed on the separation terminating side. Thereby, the recovery rate of the unpolished rice by means of the rotational separating cylinder 15 is enhanced, the rate of unpolished rice in the grain which is reduced to the husking part 1 is made small and the damage due to double husking of unpolished rice can be reduced.
