<p>A horizontal grinding type rice milling machine, comprising a rice milling chamber having grinding rolls (1) fixed around a horizontal rotating shaft (10) and a cylindrical foreign matter removal screen (S) vertically dividable into two screen half parts (2, 2) and covering the grinding rolls concentrically thereto, wherein a plurality of stoppers (3) and flaps (4) formed of arc members curved along the periphery of the circular cross section of the cylindrical screen orthogonal to the axis thereof are fixedly installed on the inner peripheral surface of each of the screen half parts (2) obtained by dividing the foreign matter removal screen (S) into two parts so as to be alternately disposed in axial direction, a distance allowing rice to pass while restricting the passing amount of rice is assured between the flaps (4) and the outer periphery of the grinding rolls (1), and a distance between the stoppers (3) and the outer periphery of the grinding rolls (1) is set so as not to pass the rice, both screen half parts (2, 2) of the foreign matter removal screen (S) are formed in the same structure and, when the screen half parts are reversed to each other so that both ends thereof in axial direction are replaced with each other, the stoppers (3) are replaced with the flaps (4), whereby at least one screen half part (2) can be installed reversely so that both ends thereof in axial direction can be replaced with each other, and the butted surfaces (J) of both screen half parts (2, 2) can be displaced in circumferential direction of the rotating shaft (10).</p> |
