And the opening degree of the rice baffle becomes insufficient along with the development of polished rice. In the rice polishing process, brown rice is circularly conveyed into the rice polishing machine and the bran removing device through the bucket elevator, and the needed finished product is obtained through repeated grinding and bran removing; the resistance of the rice baffle can be adjusted through the automatic adjusting device arranged at the discharging port according to the polished rice processing progress and detection related data, the resistance is matched with discharging pressure generated in different processing progresses, the opening degree of the rice baffle is always kept large, it is guaranteed that processing is smoothly conducted, delay and stagnation are not generated, and the quality of the polished rice is guaranteed. And the grain discharging time is also shortened.
