The invention relates to the technical field of rice milling and separating devices, and discloses a bran short removing device for rice milling processing. The device comprises a base, supporting legs are fixedly arranged at the two ends of the top surface of the base, a fixing plate is fixedly arranged at the top ends of the supporting legs, a cleaning box is fixedly sleeved with the fixing plate, the bottom of the cleaning box penetrates through the fixing plate and is fixedly provided with a discharging bin, the top of the cleaning box is fixedly provided with a separating bin, the top ofthe separating bin fixedly communicates with a rice milling bin, the top of the cleaning box is fixedly provided with a connecting bin, and the top of the connecting bin fixedly communicates with thebottom of the separating bin. According to the bran short removing device for rice milling processing, a material pumping pump is arranged to pump air inside the separating bin, the bran separated from the rice milling bin is pumped, meanwhile, a cleaning scraping piece is driven to rotate by utilizing flowing of the air, so that the rice bran inside the separating bin is stirred by the cleaning scraping piece, the problem that a large amount of rice bran is accumulated on a filter screen to block the filter screen is solved, so that the smoothness of discharging is guaranteed, and the practicability of the device is improved.
