The methods of examining rice crop products have following disadvantages at the present time; 1) the products are impossible to be divided exactly into three portions; empty grains, incompletely ripened trains, and completely ripened grains, these being the essential conponents which determine the yield, 2) the results of examination are easily disturbed by the difference in water content of the sample used, and 3) the winnower is not satisfactory to make grouping of rice grains into classes, heavier or lighter than a given grain-weight, respectively.
