[0022] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0023] like Figure 1-Figure 6 As shown, a rice bran powder removing device for rice processing provided in this embodiment comprises a feeding tray 1, a driving gear 2 is connected to the outer ring shaft of the feeding port at the lower end of the feeding tray 1, the driving gear 2 is connected to the first motor 7 through a belt, a casing 5 is installed at the lower part of the driving gear 2, a first rice screen 13 is clamped on the inner wall of the casing 5, a rice roller 19 is rotatably installed in the casing 5, a discharge pipe 16 passes through the bottom outlet of the casing 5, a pulley 14 is nested on the outer wall of the discharge pipe 16, blades 15 are evenly distributed around the bottom of the pulley 14, and a blowing chamber 22 is arranged directly below the discharge pipe 16.

[0024] The lower end of the first motor 7 is fixed to the motor mounting platform 8 by screws, and the side is fixed to the housing 5 by welding through the motor fixing frame 6. The two-way fixing method makes the first motor 7 more stable in working state.

[0025] The rice roller gear 3 is meshed with the driving wheel 2, driving the rice roller 19 to stir 360 degrees, which not only allows the rice roller 19 to rub more fully with the rice, but also allows more friction between the rice, so that the bran powder can be quickly separated.

[0026] Four circular rice outlets are evenly distributed around the lower end of the feeding pipe 16, so that the rice can be dispersed and evenly flowed out, so that the bran powder remaining on the surface can be blown away by the wind.

[0027] An operation panel 10 is detachably mounted on one side of the second motor 9 , and function buttons are arranged on the operation panel 10 to control the operation of the motor and the fan.

[0028] The fan blades 15 are made of aluminum alloy and have the advantages of good heat dissipation and low noise.

[0029] The second rice screen 17 is a conical structure and is press-connected with the blowing chamber 22. The conical shape allows the rice to flow out of the discharge port 18 smoothly without being stuck.

[0030] A second discharge hole 21 is formed through one side of the outer wall of the blowing chamber 22. The second discharge hole 21 is square.

[0031] Working principle of the device: When the device is used, the rice can be poured into the feeding tray 1. After entering the mixing chamber, the first motor 7 transmits power to the driving gear 2 through a belt. The driving gear 2 and the rice roller gear 3 are meshed to drive three groups of rice rollers 19 to achieve 360-degree uniform mixing. During the mixing process, the friction force generated by the mixing and the friction between the rice and the rice causes the bran powder to separate. The separated bran powder is discharged through the first rice sieve 13. At this time, a small amount of bran powder is still mixed in the rice. The rice flows into the blowing chamber 22 from the feeding pipe 16 at the lower end of the mixer. Under the action of wind force, the bran powder on the surface of the rice is taken away and filtered and discharged through the second rice sieve 17. Finally, the processed rice flows out through the discharge port 18, thereby solving the problem of incomplete bran powder removal during rice processing and achieving the purpose of high efficiency of bran powder in the rice processing process.

[0032] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
