In a husking apparatus comprising: a husking portion having a pair of husking rolls which are adjustable in clearance between them and rotated in opposite directions with different peripheral speeds to perform husking of paddy grain; and a supply portion disposed above the husking portion for supplying paddy grain to be husked to the husking portion, wherein the supply portion is so constructed as to supply paddy grain from the supply portion to the husking portion in the form of a layer in such a manner that a thickness of the layer of a flow of paddy grain becomes not greater than two grains at the husking portion, and the supply portion is so constructed as to supply paddy grain to the husking portion at a speed not less than a flowing-down speed corresponding to a minimum husking throughput desired of the husking apparatus so that husking is performed with a throughput not less than the minimum husking throughput, it is possible to enhance the husking throughput while minimizing the breakage of paddy grain. In cases where paddy is the one of long-grain variety of rice, the flowing-down speed of paddy grain is set to be not less than 3 m/sec when the paddy grain reaches a region around the clearance between the pair of husking rolls.
