Description
Technical Field
[0001] This application relates to the field of rice production technology, and more specifically, to a fine peeling apparatus for rice production. Background Technology
[0002] Rice peeling and milling machines play a crucial role in rice processing. Through strong friction and milling pressure, they can efficiently remove the outer husk of rice and precisely remove the outer bran, achieving the separation and discharge of rice and bran. However, to ensure complete and clean rice peeling, the rice generally needs to be peeled repeatedly. Furthermore, during rice discharge, manual handling of the rice bag is required, which is inconvenient. Therefore, we propose a fine peeling device for rice production. Utility Model Content
[0003] 1. Technical problems to be solved
[0004] The purpose of this application is to provide a fine rice peeling device for rice production, which solves the technical problems mentioned in the background art. This rice peeling device delivers rice stored in the feeding hopper evenly to the space between the inner milling tube and the porous inner tube via a spiral conveyor shaft. The inner milling tube rotates inside the porous inner tube, rubbing the rice to remove the bran, achieving a single peeling operation. The bran passes through the porous inner tube and falls into the bran receiving box. The rice enters the secondary processing box from the rice outlet, where it is repeatedly rubbed by a wire brush on a sieve plate, resulting in a secondary fine removal of the bran. The bran also passes through the sieve plate and falls into the bran receiving box, where it is discharged by a bran-discharging fan, achieving separation of rice and bran. A rice bag holder is fixedly installed on a sliding support plate on the bracket, allowing for the convenient collection of peeled rice. This frees up the hands of holding the rice bag to collect the rice, making it convenient to use and reducing labor intensity.

A rice bran receiving box is fixedly connected between the bottom end of the rice milling pipe and the secondary processing box. A rice bag rack is fixedly provided on the pallet.
[0007] By adopting the above technical solution, when using this rice hulling device, rice with bran is fed into the feeding hopper, falls into the conveying pipe, and is transported by a spiral conveyor shaft to the space between the inner milling tube and the porous inner tube. The spiral conveyor shaft drives the inner milling tube to rotate inside the porous inner tube, which rubs the rice, removing the bran. The bran passes through the porous inner tube and falls into the bran receiving box. The hulled rice enters the upper part of the sieve plate in the secondary processing box through the rice outlet. Some rice with bran attached is repeatedly slid along the screen plate by the iron brush, which, through the friction between the iron brush and the sieve plate, removes the bran. The rice bran attached to some of the rice is further finely removed.

After that, the rice is conveyed to the sieve plate of the secondary processing box. The iron brush slides repeatedly on the surface of the sieve plate to further remove the rice bran attached to the rice.

The spiral conveyor shaft 42 drives the inner milling tube 35 to rotate inside the porous inner tube 32, rubbing the rice and removing the bran. The bran passes through the porous inner tube 32 and falls into the bran receiving box 31. The peeled rice enters the upper part of the sieve plate 66 in the secondary processing box 5 through the rice outlet 34. Some rice still has some bran attached; by repeatedly sliding the iron brush 65, the friction between the iron brush 65 and the sieve plate 66 removes some of the bran. The rice bran attached to the rice is further finely removed. The removed rice bran falls through the sieve plate 66 into the rice bran receiving box 31, and is then discharged by the bran discharge fan 7.

The rice discharge port 51 is located at the bottom of the sieve plate 66. The rice milling tube 3 rotates in the porous inner tube 32 to remove the husk from the rice. After the rice is peeled, it is transported to the sieve plate 66 of the secondary processing box 5. The iron brush 65 slides repeatedly on the upper surface of the sieve plate 66 to further remove the rice bran attached to the rice. The clean rice rolls down the inclined sieve plate 66 and is discharged through the inclined plate of the rice discharge port 51.
[0037] Reference Figure 2 and Figure 3The secondary processing mechanism 6 also includes a second motor 61, which is fixedly installed on the outer surface of the secondary processing box 5.

[0040] Working principle: When using this rice peeling device, rice with bran is fed into the feeding hopper 4, and the rice falls into the conveying pipe 41. The output shaft of the first motor 21 drives the first belt mechanism 22 and the second belt mechanism 23 to rotate. The first belt mechanism 22 drives the spiral blade conveying shaft 42 and the rice milling inner tube 35 to rotate through the shaft, so that the spiral blade conveying shaft 42 conveys the rice between the rice milling inner tube 35 and the porous inner tube 32. The rice milling inner tube 35 rotates inside the porous inner tube 32, which can rub the rice and remove the bran. The rice bran passes through the porous inner tube 32 and falls into the rice bran receiving box 31. The peeled rice enters the upper part of the sieve plate 66 in the secondary processing box 5 through the rice outlet 34. The output end of the second motor 61 drives the half-face gear 62 to rotate. The half-face gear 62 causes the tooth plate 63 to repeatedly move along the secondary processing box 5. The toothed plate 63, driven by the angle bracket 64, repeatedly slides along the upper surface of the sieve plate 66, further refining the removal of rice bran attached to the rice. The removed rice bran falls through the sieve plate 66 into the rice bran receiving box 31.
