The invention relates to a novel powder screening device for producing rice protein (peptide) powder. An existing powder screening process is mainly completed by manpower manually, time and labor arewasted, the powder screening requirement may not be met, the powder screening quality cannot be ensured, and defects exist. According to the novel powder screening device for producing rice protein (peptide) powder, a feed inlet is formed in the top of a machine body, cushion blocks are symmetrically arranged at the bottom in the machine body and provided with motors, the motors are coaxially connected with a transmission shaft, the transmission shaft is coaxially connected with a driving belt wheel, the driving belt wheel is movably connected with a supporting plate, and the supporting plateis fixed to the bottom in the machine body. By adoption of a motor driving mode, a screen can be switched to move upwards or downwards or clockwise or anticlockwise continuously, the powder screeningefficiency is improved, the device replaces manpower for manual powder screening, the working efficiency is greatly improved, and time and labor are saved.
