ABSTRACT:
Prior art grinding type rice-cleaning rollers made of emery have been sintered members having a frustum of cone shape or an abacus bead shape. Their manufacture, therefore, is considerably troublesome, and they can be manufactured in only the special factories. In addition, once they are partly broken, they must be discarded. According to the present invention a plurality of rectangular elongate grinding type roller elements made of emery are arranged side by side on the outer periphery of a rotary member by the suitable means. Thus, it can be easily manufactured, so that its cost is very low. In addition, if it is partly broken, only the broken roller element may be replaced.
