METHOD AND APPARATUS OF POLISHING BROWN RICE BRAN LAYER

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus of polishing a brown rice bran layer, capable of polishing and grinding a brown rice bran surface layer extremely thinly by one tenth or less by grinding the surface of brown rice, making it possible to handle the rice not as "polished rice" but as brown rice even when the brown rice bran surface layer is polished, making moisture absorption several times as fast as the brown rice, producing sweetness, and extending application fields.;SOLUTION: The polishing apparatus of the brown rice bran layer is configured such that the brown rice is transferred in an axial direction through the space S of polishing recessed parts surrounded by a plurality of projection parts 11 projected on a polishing roll 10 by such a random arrangement that the brown rice can be transferred in the axial direction between the surface of the polishing roll 10 and a bran removing screen 12 on the outer side, a guide groove 14 provided on one surface of each projection part 11 is positioned on the forward movement surface side in the rotating direction of the polishing roll 10, brown rice grain surface is rotated and polished while bringing brown rice grains into contact with each other to friction each other by mixing and moving them inside the space S of each polishing recessed part and the space between the projection parts 11 adjacent in the rotating direction by rotating the polishing roll 10, and the brown rice bran layer is polished extremely thinly by one tenth or less.;COPYRIGHT: (C)2009,JPO&INPIT
