Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, specifically to a rice surface polishing machine for rice processing. Background Technology

[0002] Rice surface polishing, also known as rice finishing, is a deep polishing process that removes the germ, husk, and part of the bran layer from the rice grains. This results in a smooth, white surface with an appealing sheen, ensuring the rice remains clean and hygienic during subsequent production, storage, and transportation. It also reduces bran adhesion and rice flour shedding, improving the rice's shelf life and making it less prone to mold.

[0003] The invention disclosed in CN118357007A is a rice surface polishing device for rice processing. It realizes the transfer of rice grains in the radial direction of the polishing roller, realizes the alternating approach of rice grains to the polishing roller, and prevents the situation where the amount of rice grains in the polishing chamber is too large, resulting in the rice grains not transferring between the outer and inner chambers. It solves the problem of uneven polishing of rice grains caused by the continuous movement of rice grains away from or close to the polishing roller.

[0004] However, the above-mentioned surface polishing device for rice processing still has the following problems in actual use: Although the surface polishing operation of rice is achieved by bidirectional feeding, the processing efficiency of this type of polishing mechanism is low and cannot meet the needs of batch polishing. At the same time, the rice scraps during polishing cannot be separated by water mist, and will still stick to the surface of the rice, affecting the output and requiring subsequent filtration and screening.

[0005] Therefore, we propose a rice surface polishing machine for rice processing to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a rice surface polishing machine for rice processing. It solves the problem that the existing rice surface polishing operation is achieved by bidirectional feeding. However, the processing efficiency of such polishing mechanism is low and cannot meet the needs of batch polishing. At the same time, the rice dust during polishing cannot be separated by water mist, and will still stick to the rice surface, affecting the output and requiring subsequent filtration and screening.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rice surface polishing machine for rice processing, comprising a polishing machine body and a drive guide groove formed inside the polishing machine body; further comprising:

[0008] The polishing machine body is equipped with a filtration mechanism, which includes a filter screen barrel. The filter screen barrel is rotatably mounted in the drive guide groove inside the polishing machine body in a lockable manner.

[0009] The polishing machine body is equipped with a polishing mechanism inside, and the polishing mechanism includes a polishing guide plate, which is rotatably mounted on the left and right ends inside the polishing machine body via bearings.

[0010] Preferably, the filtration mechanism includes filter screen holes, which are opened at equal angles on the outside of the filter screen barrel, and a closable rice feeding area is provided at the top center of the filter screen barrel.

[0011] Preferably, the filtration mechanism includes a reciprocating screw, which is rotatably mounted at the rear center of the polishing machine body via bearings, and the outer walls of both sides of the reciprocating screw are threaded to the bottom end of the spray bracket.

[0012] Preferably, the top of the spray bracket included in the filtration mechanism extends above the top surface of the polishing machine body, and a spray nozzle is fixedly provided on the bottom surface of the top of the spray bracket. The top of the spray bracket is connected to the water supply tank, and the water supply tank is fixedly installed on the front of the polishing machine body.

Polishing guide rollers are rotatably arranged inside the chip removal column at equal angles, and the outer side of the polishing guide rollers arranged at equal angles extends through the outer side of the chip removal column.

[0014] Preferably, the polishing mechanism includes a drive shaft, the middle part of which is fixedly disposed at the internal center of the chip removal column, and the outer end of the drive shaft passes through the outside of the polishing machine body through a bearing. The right end of the drive shaft is engaged with the right end of the reciprocating screw through a pulley assembly.

[0015] Preferably, the polishing mechanism includes a guide gear, which is fixedly disposed at the end of the outer polishing guide roller on the right side of the polishing machine body at equal angles, and a positioning gear is fixedly disposed in the middle of the right side of the polishing machine body, and the positioning gear is meshed with the guide gear.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This rice surface polishing machine for rice processing involves feeding rice into the gap between the filter screen, the chip removal column, and the polishing guide roller. The chip removal column drives the polishing guide roller to revolve and rotate to polish the rice. Reciprocating spray nozzles assist in separating rice chips, improving the efficiency and convenience of the rice polishing process. The specific details are as follows:

[0018] 1. Rice is fed into the filter screen barrel through the rice feeding area. The rice is placed in the gap between the filter screen barrel and the chip removal column. The filter screen barrel is stationary relative to the polishing machine body so that the rice can be rotated and polished. After the polishing operation is completed, the filter screen barrel rotates 90° so that the polished rice can be discharged and collected through the rice feeding area.

[0019] 2. The drive shaft rotates along with the polishing guide plate and the chip removal column. The polishing guide roller embedded inside the chip removal column rotates synchronously. The guide gear and the positioning gear mesh with each other, causing the meshing guide gear and the polishing guide roller to rotate. This allows the chip removal column and the polishing guide roller to carry the rice through the filter screen for surface polishing, thus adapting to the efficient polishing operation of rice of different specifications.

[0020] 3. The drive shaft drives the reciprocating screw to rotate via the pulley assembly, and the threaded spray bracket moves back and forth. Water is then supplied to the spray bracket through the water supply tank, so that water can be sprayed onto the filter screen through the spray nozzle to help separate the polished rice scraps and other debris. The scraps are then drained through the bottom opening of the polisher body, eliminating the need for subsequent filtration and screening. Attached Figure Description

[0031] The polishing mechanism includes a chip removal column 11 rotatably disposed inside the filter screen 3 included in the filtration mechanism. The gap between the filter screen 3 and the chip removal column 11 is used to store rice, and the rotation of the chip removal column 11 and the polishing guide roller 12 is used to polish the surface of the rice.

[0032] like Figure 3 , Figure 5 As shown, when it is necessary to perform surface polishing on rice, the rice feeding area 6 at the top of the filter screen 3 is first opened so that rice can be fed into the filter screen 3 through the rice feeding area 6. During this process, the rice is always in the gap between the filter screen 3 and the chip removal column 11. During the polishing process, the filter screen 3 is stationary relative to the polishing machine body 1 in a fixed manner so that the polishing mechanism can drive the rice to rotate and polish. After the polishing operation is completed, the filter screen 3 is rotated downward by 90° to correspond to the opening at the bottom of the polishing machine body 1, and then the polished rice is discharged through the rice feeding area 6.

[0033] Example 2: To address the problems existing in current surface polishing machines for rice processing, this example provides the following technical solution: The polishing machine body 1 is internally equipped with a polishing mechanism, which includes a polishing guide plate 4. The polishing guide plate 4 is rotatably mounted on the left and right ends of the polishing machine body 1 via bearings. The polishing mechanism includes a chip removal column 11, which is fixedly installed in the middle of the inner side of the polishing guide plates 4 at both ends.

[0034] The polishing mechanism includes a guide gear 15, which is fixedly disposed at the end of the outer polishing guide roller 12 on the right side of the polishing machine body 1 at equal angles. A positioning gear 16 is fixedly disposed in the middle of the right side of the polishing machine body 1, and the positioning gear 16 is meshed with the guide gear 15.

[0035] like Figures 3-4 , Figure 6 As shown, the motor installed on the right side of the polishing machine body 1 drives the drive shaft 13 to rotate with the polishing guide plate 4 and the chip removal column 11.
