Patent ID: 6951169

Claim:
A horizontal grinding-type rice polishing machine, comprising: a grinding roller ( 1 ) fixedly and circularly installed on a horizontal rotation axis ( 10 ); a concentric cylindrical bran removing screen (S), which can be separated into longitudinally split two screen halves ( 2 ); and a stopper ( 3 ) or a flap ( 4 ), wherein the grinding roller ( 1 ) is covered with the concentric cylindrical bran removing screen (S) to thereby form a rice polishing room, and wherein the stopper ( 3 ) or the flap ( 4 ) is fixedly provided on an inner peripheral surface of each of the two-part split screen halves ( 2 ) of the bran removing screen (S), the stopper ( 3 ) or the flap ( 4 ) being formed by a circular arc member which curves along the circumference of a circular cross section perpendicular to the axial center of the cylinder, so that between the flap ( 4 ) and the outer periphery of the grinding roller ( 1 ), a distance that allows passing of rice while restricting passing amount is secured, and a distance between the stopper ( 3 ) and the outer periphery of the grinding roller ( 1 ) prevents the rice from flowing; wherein both of the screen halves ( 2 ) of the bran removing screen (S) have the same structure, and are so configured that when the respective ends in the axial direction are inverted, the stopper ( 3 ) and the flap ( 4 ) are inverted, and in the rice polishing machine, at least one screen half ( 2 ) can be arranged so that the respective ends in the axial direction are inverted.
