The clean brown rice obtained by husking and separating the rice from the husk contains a lot of fiber on the surface of the cortex, which affects the edible quality. A rice peeling device is needed to grind the cortex of the brown rice. After searching, the patent document with the authorization announcement number CN220425421U announced a rice peeling device for rice production and processing, including a peeling box, a stirring chamber is provided near the top of the peeling box, a motor is provided at the top of the peeling box, a rotating rod is connected to the execution end of the motor, stirring rods are equidistantly provided on the rotating rod, and raised friction blocks are equidistantly provided on the stirring rod.

[0029] In this embodiment, in order to improve the effect of friction peeling of brown rice, a plurality of evenly distributed grinding beads are fixedly mounted on the plurality of first grinding rollers 6 and the plurality of second grinding rollers 7.

[0030] In this embodiment, in order to ensure that all the brown rice after preliminary friction peeling falls between the two peeling friction rollers 8, a frustum-shaped material guide cover 11 is fixedly installed in the peeling processing cylinder 1. The frustum-shaped material guide cover 11 is located between the vertical axis 5 and the peeling friction roller 8, and the inner diameter of the frustum-shaped material guide cover 11 decreases from top to bottom.

[0035] Through the above structure, the peeling device for rice production provided by the present application can improve the peeling quality by performing a secondary friction peeling process on the brown rice, and can also lift the rice and bran obtained after the secondary peeling in the surrounding space, and can absorb the bran more comprehensively and thoroughly, ensuring that the rice and the bran are more thoroughly separated, thereby improving the quality of the rice peeling process.

By utilizing the suction force generated by the operation of the dust suction fan 21, the bran can be sequentially passed through multiple suction plates. The dust branch pipe 24, the annular pipe 23, the dust suction main pipe 22, the dust suction fan 21 and the dust discharge pipe 25 enter the collection box 20 for storage, thereby being able to more comprehensively and thoroughly suck away the bran, so that the rice and the bran are more comprehensively and thoroughly separated. The rice without the bran will continue to fall onto the screen 17, and the screen 17 can be used to screen and separate the whole rice grains and the broken rice grains, so that the whole rice grains are discharged through the rice discharge pipe 18, and the broken rice grains are discharged from the broken rice discharge port 19 through the sieve holes on the screen 17.
