Abstract

PROBLEM TO BE SOLVED: To sort out cereals as good grains and waste grains and separate/ remove foreign matter included in the good grains to obtain the good grains of high quality. SOLUTION: A vertical cereals separator part E2 is arranged on a stone sorter part E1 and sorts out cereals supplied from a hopper 52 as the good grains and the waste grains by relatively rotating a sorting reticular body 57 and a grain lifting helical cylinder 60 arranged concentrically in a shell body 51 and lifts the good grains to a good grain delivery chamber 62. Thus the good grains delivered from the chamber 62 fall into a hopper part 5 of the stone sorter part E1 through a chute 63. Further, in the stone sorter part E1, the foreign matter included in the good grains is separated/removed by the interaction of a selector plate 17 which rocks integrally with an air chamber 10 and an air flow by a fan 12.
