PROBLEM TO BE SOLVED: To make it possible to easily remove small rice clogged in a small rice separating net formed to a cylindrical shape so as to enclose the outer periphery of a spiral conveyor for grain lifting by housing this small rice separating net into a casing and providing the outer periphery thereof with a clogging rice removing means freely slidable in the axial direction of the small rice separating net. ;SOLUTION: Milled rice subjected to polishing is transferred from below to above the cylindrical body 11 by rotation of the spiral vanes of the spiral conveyor 9. At this time, the small rice in the milled rice is splashed in the outer peripheral direction of the spiral vanes by the centrifugal force of the spiral vanes. The small rice splashed in the position of a small rice separating chamber 10 is passed through the respective meshes of the separating net 11a and is released into a small rice falling space 6a. An operator slides a coil spring 15 by vertically operating the knob part 17c of a rod 17 for sliding when the meshes of the separating net 11a are clogged with the small rice by the execution of the sepn. of the small rice and the degradation in the small rice separation capacity is resulted. Since the press contact part of the coil spring 15 inclines in the sliding direction, the force in the circumferential direction of the separating net 11a is also acted on the small rice and the clogging rice is thus removed.;COPYRIGHT: (C)1997,JPO
