The husker, also known as the husker, is a grain processing machine that husks rice to make brown rice. It can remove the hull of rice, reduce the explosion and skin damage of rice, and keep the integrity of brown rice as much as possible. It mainly consists of a hopper feeding device, a machine head device, a chaff separation chamber, a gear box and a frame.

Common sheller includes rubber roller sheller, sand table sheller and centrifugal sheller. Take the rubber roller husker as an example;

Working principle of rubber roller husker

The main working parts of rubber roller husker are a pair of horizontal rubber rollers or plastic rollers bonded or covered with rubber layer on cast iron drum. The axes of the two rollers are on the same horizontal plane or slightly different in height, and rotate in opposite directions at different speeds, wherein the position of one roller is fixed and the other roller can move, so that the rolling distance between the two rollers can be adjusted. The difference between the linear velocities of the two rollers is 2 ~ 3.2m/s, and the sum of the linear velocities should not exceed 30m/s ... Rice is evenly fed between the two rollers through the drip plate (or through the feeding roller and the drip plate) on the whole length of the cots, and the equal-diameter rollers rotate reversely at different linear velocities, so that the rice passing between the rollers is squeezed and torn by the pressure of heavy objects. Due to the extrusion of the two rollers and the tearing caused by the speed difference between the two rollers, most of the rice husks reach the purpose of hulling, enter the chaff separation device, and then suck out the rice husks through the suction port at the wind speed of 4-5 m/s.
