Abstract

This polishing-type horizontal rice milling machine is capable of improving rice milling efficiency by assuring the fluidity of rice grains even when the supply amount of rice grains is increased to increase the fill-level of a milling chamber with rice grains. The polishing-type horizontal rice milling machine is configured by forming, in the circular outer circumferential surface of a polishing roll, agitation grooves extending in the axial direction, and by forming a plurality of air injection holes in each of the grooves. Rice milling is carried out in the milling chamber by air being injected from the air injection holes while the polishing roll is being rotationally driven.
