The invention relates to the field of rice polishing equipment, in particular to a rice polishing device. The rice polishing device comprises an operation box, a driving part is arranged at the bottomof the operation box, an output shaft of the driving part is coaxially connected with a rotating shaft penetrating through the operation box, the operation box is internally provided with a partitionplate dividing the operation box into an operation box upper part and an operation box lower part, stirring blades are arranged on the part, on the upper part of the operation box, of the rotating shaft, the lower part of the operation box is fixedly connected with a screen mesh, a convex block is arranged at the bottom of the screen mesh, a pressing rod capable of pressing the convex block is arranged on the part, on the lower part of the operation box, of the rotating shaft, the partition plate is internally provided with a groove, the groove is internally provided with an electromagnet anda permanent magnet, a power supply controlling the electromagnet is arranged on the top wall of the operation box, and the rotating shaft is rotatably matched with the partition plate and the screenmesh. According to the scheme, the rice polishing device is used for rice polishing, produced fine grained rice bran powder can be adsorbed, and thus the effect of removing the rice bran powder in thepolishing process is better.
