[0002] Rice, also known as rice, is a food made from rice grains after cleaning, husking, milling, and finished product finishing. Rice contains nearly 64% of the nutrients in rice and more than 90% of the nutrients required by the human body. It is also the main food for people in most areas. In the rice processing process, a lifting device is needed to lift the rice into the rice processing equipment for processing. After searching: Patent No. CN117563700A is a lifting device for rice processing. In view of the problem that the current rice lifting device cannot remove the rice dust in the rice and reduce the temperature, the following scheme is proposed, including a feed bottom box, a feed slot is opened on the top of the feed bottom box, and a vertically arranged lifting chassis is fixed to one end of the top of the feed bottom box by bolts, and the top and bottom between the inner walls on both sides of the lifting chassis are fixed with driving rollers through bearings.
