Abstract

A husking apparatus (1) for cereals comprises a pair of rolls (7, 8) provided to each other with a clearance therebetween, and an inclined guide chute (13, 33) situated above the rolls. The guide chutes sides down cereal grains between the rolls, and the rolls (7, 8) rotate in opposite directions, respectively, to nip and shell the cereal grains therebetween. The guide chute and the rolls are located so that a guide surface (13a) of the guide chute is substantially perpendicular to a line (R) connecting the centers of rotational shafts, and that an extension line (s) from the guide shafts (13a) passes within a range of ±10 mm on both sides of a middle a point (M) of the clearance between the first and second rolls (7, 8). The guide surface (13a) of the guide chute has such an inclination that the cereal grains spread all over a width of the guide surface in the substantially single layer of a band-like shape and are accelerated up to a speed less than peripheral speeds of the rolls (7, 8) while they slide down along the guide surface. The cereal gains are thus uniformly fed between the rolls in regular postures and have less irregular reflection due to collision with the rolls, and it is possible to perform reliable husking which causes less broken grains.
