ABSTRACT:
Apparatus is disclosed for polishing rice grains for generating super luster on rice grain surfaces which comprises means for grind-polishing rice grains from unpolished rice grains into intermediately polished rice grains whereby the yield of said intermediately polished rice grains from said unpolished rice grains is maintained equal to or not less than approximately 94%. The present invention also includes structure for feeding 2-50 kg of water per hour and 12-90 m.sup.3 air per hour to intermediately polished rice grains that are flowing at a rate of one ton per hour whereby moisture of 0.1-2.0 weight percent to the rice grains, weight is absorbed and stuck onto surfaces of the rice grains during friction-polishing. The disclosed rice polishing apparatus includes a grinding-type polishing machine provided with grinding type polishing rolls and a humidified friction-type polishing machine provided with friction type polishing rolls and humidifying device.
