Description

Technical Field

[0002] A rice milling machine is a mechanical device that removes the outer husk of rice, processing brown rice into white rice while separating rice, bran, and broken rice. During the processing of brown rice using rice milling machines currently on the market, the bran powder produced can easily clog the sieve holes on the rice sieve inside the rice milling machine. If the bran powder cannot be discharged from the rice sieve in time, it will cause the internal temperature of the rice milling machine to rise. Over time, the bran powder will form bran clumps on the surface of the rice sieve, which will affect the operation of the rice milling machine. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a spray cleaning and bran removal device, which can effectively prevent rice screens from being blocked by bran powder, thus ensuring the reliable operation of the rice milling machine.

[0016] See Figures 1-2As shown in the embodiment of this application, a spray cleaning and bran removal device is disclosed, including a rice milling machine body 1; a spray device is fixed in the rice milling chamber of the rice milling machine body 1, the spray device is used to spray high-pressure air onto the rice sieve located inside the rice milling chamber to blow away the bran powder on the rice sieve; the spray device includes an air outlet 2 and a plurality of nozzles 3 spaced apart along the axial direction of the air outlet 2; the air outlet 2 is fixed to the rice milling machine body 1, one end of the air outlet 2 is sealed, and the other end of the air outlet 2 is connected to a high-pressure air supply unit; all nozzles 3 are fixed on the air outlet 2, and the air inlet end of each nozzle 3 is connected to the inner cavity of the air outlet 2, and the air outlet end of all nozzles 3 is facing the rice sieve.

[0017] Each nozzle 3 has an interface 31 at its air inlet end. The outer diameter of the interface 31 is smaller than the outer diameter of the air inlet end of the nozzle 3. The air outlet 2 has exhaust holes 21 that correspond one-to-one with several nozzles 3. Each interface 31 is inserted into the corresponding exhaust hole 21. Each interface 31 is welded and fixed to the corresponding exhaust hole 21 and circumferentially sealed.

This structure allows for easy connection of the other end of the air outlet to the high-pressure air supply unit and offers the advantage of a simple connection structure. The high-pressure air supply unit includes an air compressor and a solenoid valve. The air inlet of the solenoid valve is connected to the air outlet of the air compressor, and the quick connector is connected to the air outlet of the solenoid valve via an air inlet hose.
