JPS6427651A - Method of polishing cereal - Google Patents

Abstract

PURPOSE: To polish grains deep into the ruggedness of their surfaces. by providing the method with a stage for mixing grains and polishing grains, agitating the mixture and polishing the grain surfaces. a stage for classifying the polished grains and the polishing grains and a stage for recycling the separated and polished grains. CONSTITUTION: The grains are polished by the polishing stage for mixing the grains and the polishing grains and agitating the mixture, the stage for classifying the polished grains and the polishing grains and the stage for recycling the polished grains. There is provided, for example, a screw transporting device as the device. The grains and the polishing grains and preferably shredded fabric pieces are fed from its feeding port 42. The screw is then rotated to bring the polishing grains and the shredded fabric pieces into contact while transporting the grains. The grains are then polished deep into the rugged surfaces by contact with the polishing grains, by which their mud and stuck matter are removed. Simultaneously the grain surfaces are polished by the contact of the grains and the shredded fabric pieces. The polishing grains and the shredded fabric pieces are classified and recovered by a classifying device 46 and are then recycled.
