Abstract

PROBLEM TO BE SOLVED: To provide a sorter wherein mixed rice can be uniformly fed onto each swing sorting plate by a simple structure, and the reduction in cost is possible. SOLUTION: The sorting section 10B of a hulling sorter 10 is formed on the right side of a hulling section 10A and has a swing sorting plate 74 slanted so that it may be high on the right, may be low on the left, may be high in the rear, and may be low in the front. The hulled mixed rice is fed onto the swing sorting plate 74 from the corner situated on the side of the hulling section 10A and being left to and rear to the swing sorting plate 74. That is, the mixed rice is fed to the swing sorting plate 74 from the position nearest to the hulling section 10A, so that a feed plate and a distribution trough which is heretofore indispensable to feed mixed rice onto the swing sorting plate 74 can be dispensed with. This can realize the simplification of a structure, the reduction in the number of components used, and the improvement of the easiness of assembling, eventuating in the reduction in cost.
