When passing through the blast port (23), the husks of the wheat that have fallen off will be blown into the interior of the outlet pipe (22) by the blower (24), and then discharged through the blast port (23);

Next, the wheat raw material falls onto the transfer belt (31) through the leaking plate (33), and the wheat raw material is transferred to the conveyor belt (42) through the transfer belt (31). The conveyor belt (42) is provided with fine holes for air circulation, and the wheat is transported as the conveyor belt (42) rotates.

Finally, the wheat is on the conveyor belt (42) and moves forward, during which it collides with the kneading belt (46). After the collision, the rotation direction of the kneading belt (46) is opposite to that of the conveyor belt (42), which can prompt the kneading belt (46) to knead the wheat on the conveyor belt (42) to remove the removed husks. As the fan (24) rotates, the husks are sucked upward. In addition, another set of fans is set at the bottom end of the lower bracket (11) to correspond to the fan (24). The generated wind blows upward to blow the husks onto the surface of the kneading belt (46). As the kneading belt (46) rotates, the husks that are kneaded and crushed are blown into the interior of the outlet pipe (22) through the holes on the air outlet (23), and finally the husks are discharged.
