It utilizes the mechanical force generated by machinery to remove the husk from brown rice and whiten it; the machinery used is called a rice milling machine.

[0003] A search revealed that utility model patent CN220824853U discloses "a novel rice milling machine". This novel rice milling machine is equipped with a feeding component to prevent rice grains from splashing to the outside of the hopper during rice milling. It also features a rice milling mechanism to facilitate the separation of bran from white rice, a bran removal mechanism to clean the separated bran, a filtering component to further filter the bran adhering to the white rice, and a bran discharge component to facilitate the discharge of the bran after secondary filtration.

[0004] Rice bran is divided into coarse bran and fine bran, which usually have different uses. However, this device cannot separate rice bran into coarse and fine bran, making it very inconvenient to use.

[0005] Therefore, it is necessary to provide a rice milling machine with a secondary bran removal function to solve the above-mentioned technical problems. Utility Model Content

[0014] Compared with related technologies, the rice milling machine with secondary bran removal function provided by this utility model has the following beneficial effects:

[0015] This invention provides a rice milling machine with a secondary bran removal function. During operation, the milled rice and bran are blown by a second fan as they fall. The rice falls onto the upper part of the first baffle and then falls from the right end, while the bran is blown into the side chamber. Fine bran passes through the filter belt and enters the first discharge port, exiting from the bottom. Coarse bran is filtered by the filter belt and continuously blown by the fan, becoming trapped between two sets of limiting strips. A first motor drives a rotating rod, causing the filter belt to rotate. The bran then rotates upwards along the filter belt. Meanwhile, the first fan continues to work. When the coarse bran is conveyed to the outlet of the first fan, it can be blown into the second discharge port and finally discharged from the bottom of the second discharge port. This device can screen rice bran into coarse and fine parts, which is very convenient to use. Rice falls into the feeding trough along the first baffle. At this time, the third motor drives the rotating roller to rotate. The rotating roller drives the brush head to rotate, which can clean the surface of the rice. At the same time, the exhaust fan works to pull out the cleaned rice bran. The cleaned rice falls from the bottom of the feeding trough and is then discharged from the discharge port. This device can perform secondary bran removal on rice, and the bran removal effect is good. Attached Figure Description

[0027] The working principle of the rice milling machine with secondary bran removal function provided by this utility model is as follows:

[0028] Step 1: During operation, the rice and rice bran that have been milled are blown by the air blown by the second fan 11 as they fall. At this time, the rice falls to the top of the first baffle 10 and falls from the right end of the first baffle 10, while the rice bran is blown into the side box 2. At this time, the fine bran passes through the filter belt 8 and enters the first discharge port 3, and is discharged from the bottom of the first discharge port 3. The coarse bran is filtered by the filter belt 8 and is continuously blown by the air and stuck between the two sets of limiting strips 9. The first motor 6 drives the rotating rod 7 to rotate, which can drive the filter belt 8. At this time, the rice bran will rotate upward along the filter belt 8. While the filter belt 8 is rotating, the first fan 5 continues to work. When the coarse bran is conveyed to the air outlet of the first fan 5, it can be blown into the second discharge port 4 and finally discharged from the bottom of the second discharge port 4.

[0029] Step 2: The rice falls into the feeding trough 17 along the first baffle 10. At this time, the third motor 20 drives the rotating roller 18 to rotate. The rotating roller 18 drives the brush head 19 to rotate, which can clean the surface of the rice. At the same time, the exhaust fan 21 works to pull out the cleaned rice bran. The cleaned rice falls from the bottom of the feeding trough 17 and is then discharged from the feeding port 24.

[0030] Compared with related technologies, the rice milling machine with secondary bran removal function provided by this utility model has the following beneficial effects:

[0031] During operation, the milled rice and rice bran are blown by the air from the second blower 11 as they fall. The rice falls onto the top of the first baffle 10 and falls from the right end of the first baffle 10, while the rice bran is blown into the side chamber 2. The fine bran passes through the filter belt 8 and enters the first discharge port 3, exiting from the bottom of the first discharge port 3. The coarse bran is filtered by the filter belt 8 and continuously blown by the air, becoming stuck between the two sets of limiting strips 9. The first motor 6 drives the rotating rod 7 to rotate, which in turn drives the filter belt 8. The rice bran then rotates upwards along the filter belt 8. Simultaneously, the first blower 5 continues to operate. When the coarse bran is conveyed to the outlet of the first blower 5, it can be blown into the second discharge port 4 and finally discharged from the bottom of the second discharge port 4. This device can screen the rice bran into coarse and fine parts, which is very convenient to use. The rice falls into the feeding trough 17 along the first baffle 10. At this time, the third motor 20 drives the rotating roller 18 to rotate. The rotating roller 18 drives the brush head 19 to rotate, which can clean the surface of the rice. At the same time, the exhaust fan 21 works to pull out the cleaned rice bran. The cleaned rice falls from the bottom of the feeding trough 17 and is then discharged from the discharge port 24.
