[0030] This solution has the following working process: During use, the rice to be processed is first fed into the feed pipe 17 through the top opening. The multiple guide plates 22 cause the rice to fall evenly and continuously along an S-shaped path onto the two cleaning rollers 13. The motor a7 is then started, and its output drives one of the cleaning rollers 13 and its gear a10 to rotate. The meshing of the two gears a10 drives the other cleaning roller 13 to rotate, causing the two cleaning rollers 13 to rotate in opposite directions. This allows the cleaning brushes 14 on the two cleaning rollers 13 to remove powder and other impurities adhering to the surface of the rice. The dust pump 2 creates negative pressure within the air duct 1 and the cavity 23. The cleaning brush 14 is used to remove dust and other impurities through multiple suction holes 24.
