ABSTRACT:
Provided is a rice polishing machine of a vertical shaft and frictional type, comprising a vertical tubular member, having a perforated wall; a vertical main shaft rotatably disposed in the tubular member and having one end part and an other end part; a spiral rotor fitted on the one end part of the vertical main shaft; a polishing rotor having an outer peripheral surface on which agitating projection ridges are formed, fitted on the other end part of the main shaft and further having a center axis around which the polishing rotor rotates in a certain rotating direction; and a polishing chamber mainly defined by the tubular member and the polishing rotor and having upper and lower ends one of which is connected with a rice grain feed section and the other of which is connected with a rice grain discharge section, wherein the peripheral surface of the polishing rotor is formed such that the distance between the center axis of the polishing rotor and a part of the peripheral surface of the polishing rotor, which is forward of each of the agitating projection ridges as viewed in the certain rotating direction of the polishing rotor, is smaller than the distance between the center axis of the polishing rotor and a part of the outer peripheral surface, which is rearward of each of the agitating projection ridges.
