Description

Technical Field

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

[0002] After being hulled, paddy rice becomes brown rice. Brown rice, after having most of its bran and part of its germ removed, becomes white rice. At this point, the surface of the rice grains still has a small amount of bran powder, which affects the appearance, storage quality, and taste of the cooked rice. Therefore, it needs to be removed through a "polishing" process. Polishing is a step in rice processing. In this process, the rice grains separated from the paddy not only have a much thinner layer of bran removed in the polishing machine, but also some impurities are removed.

[0003] According to Chinese Utility Model Application No. 202221659734.7, a polishing machine for rice processing is proposed. The invention describes that "this polishing machine for rice processing, by setting up components such as a circular cover, an annular fixing block, and a polishing brush, and through the mutual cooperation between the circular cover component and the annular fixing block component, the circular cover component can drive the annular fixing block by rotating, thereby achieving the effect of quickly replacing the polishing brush by rotating the circular cover."

[0004] In this rice processing polishing machine, when the polishing brush and polishing chamber are used to polish rice, rice powder easily adheres to the inner wall of the polishing chamber. The staff needs to open the polishing chamber regularly to clean the rice powder, which is cumbersome, time-consuming and labor-intensive, affecting maintenance efficiency. Therefore, a polishing device for rice processing is proposed to solve the above problems. Utility Model Content

[0012] Furthermore, a door is embedded on the outside of the hopper body, and the width of the door is greater than the width of the cleaning plate.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This polishing equipment for rice processing consists of a hopper, a feeding mechanism, a discharge pipe, a polishing mechanism, a cleaning mechanism, and an adsorption mechanism. Rice enters the feeding mechanism, which filters the rice, removing impurities. The rice then enters the hopper, where the polishing mechanism, in conjunction with the hopper, polishes the rice.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-7 The polishing equipment for rice processing in this embodiment includes a bin 1, a feeding mechanism 2, a polishing mechanism 4 and an adsorption mechanism 6 on the bin 1, a discharge pipe 3 connected to the bottom of the bin 1, a valve fixedly installed on the outside of the discharge pipe 3, and a cleaning mechanism 5 on the polishing mechanism 4.

[0025] Specifically, rice enters the feeding mechanism 2, which filters the rice. Impurities are located inside the feeding mechanism 2. The rice then enters the silo 1. The polishing mechanism 4 works with the silo 1 to polish the rice. The cleaning mechanism 5 works with the adsorption mechanism 6 to clean the rice powder. After polishing, the discharge pipe 3 is opened, and the rice is discharged along the discharge pipe 3. This reduces the number of times staff need to open the silo 1 to clean the rice powder. The operation is simple, time-saving, and labor-saving, improving maintenance efficiency.

[0026] In this embodiment, the feeding mechanism 2 includes a feeding cylinder 21, which is fixedly connected to the top of the silo body 1. A box body 22 is placed on the top of the feeding cylinder 21, and a filter plate 23 is embedded at the bottom of the box body 22. The filter holes of the filter plate 23 are larger than the grain size of rice. A cover body 24 is placed on the top of the box body 22, and a slot matching the feeding cylinder 21 is opened at the bottom of the cover body 24.

[0027] Specifically, open the lid 24, pour the rice into the box 22, filter the rice with the filter plate 23, and place the impurities on top of the filter plate 23 before the rice enters the compartment 1.

[0028] In this embodiment, the polishing mechanism 4 includes a motor 41, which is fixedly connected to the outer wall of the chamber 1. The output end of the motor 41 passes through the chamber 1 and is fixedly mounted with a polishing roller 42. The side of the polishing roller 42 away from the output end of the motor 41 is rotatably connected to the inner wall of the chamber 1 through a bearing. Polishing strips 43 are fixedly mounted on the outside of the polishing roller 42. The polishing strips 43 are made of wear-resistant material and have an arc-shaped cross-section. There are multiple polishing strips 43, which are evenly and equidistantly distributed on the outside of the polishing roller 42.

[0029] Specifically, by turning on the motor 41, the motor 41 drives the polishing roller 42 and polishing strip 43 to rotate, and the polishing strip 43 works with the bin body 1 to polish the rice.

[0030] In this embodiment, the cleaning mechanism 5 includes a spring 51, and a groove is provided inside the polishing roller 42. The spring 51 is fixedly connected to the inner wall of the groove. A movable plate 52 is fixedly installed on the side of the spring 51 away from the inner wall of the groove. The gap between the movable plate 52 and the groove is smaller than the grain size of rice. A cleaning plate 53 is provided on the side of the movable plate 52 away from the spring 51, which is in contact with the inner wall of the silo body 1. The cleaning plate 53 is made of sponge or rubber. The cleaning plate 53 is threadedly connected to the movable plate 52 by bolts. The bolts are located inside the cleaning plate 53. A silo door is embedded on the outside of the silo body 1. The silo door is sealed to the silo body 1 by a sealing ring. The width of the silo door is greater than the width of the cleaning plate 53.

[0031] Specifically, by opening the compartment door and unscrewing the bolts from the inside of the cleaning plate 53, the cleaning plate 53 can be disassembled. By screwing the bolts back into the cleaning plate 53, the cleaning plate 53 can be installed. By turning on the motor 41, the motor 41 drives the polishing roller 42, polishing strip 43, spring 51, moving plate 52, and cleaning plate 53 to rotate. The spring 51 is in a compressed state, causing the cleaning plate 53 to fit against the inner wall of the compartment 1. The cleaning plate 53 cleans the rice powder inside the compartment 1.

[0032] In this embodiment, the adsorption mechanism 6 includes an air pump 61, which is fixedly connected to the outside of the chamber 1. The air inlet of the air pump 61 is connected to an air inlet pipe 62 that penetrates through and extends into the interior of the chamber 1. The cross-section of the air inlet pipe 62 is L-shaped. A filter screen is fixedly installed at the bottom of the air inlet pipe 62. The filter screen has a pore size smaller than that of rice grains. The air outlet of the air pump 61 is connected to an air outlet pipe 63.

[0033] Specifically, by turning on the air pump 61, rice powder passes through the filter screen and enters the interior of the air inlet pipe 62, and is then discharged along the air outlet pipe 63.

[0034] The working principle of the above embodiments is as follows:

[0035] The operator opens the cover 24 and pours rice into the box 22. The filter plate 23 filters the rice, and impurities are located on the top of the filter plate 23. The rice enters the bin 1. By turning on the motor 41, the motor 41 drives the polishing roller 42, polishing strip 43, spring 51, moving plate 52 and cleaning plate 53 to rotate. The polishing strip 43 works with the bin 1 to polish the rice, and the cleaning plate 53 cleans the rice powder inside the bin 1. By turning on the air pump 61, the rice powder passes through the filter screen and enters the air inlet pipe 62, and then is discharged along the air outlet pipe 63. After polishing is completed, the discharge pipe 3 is opened, and the rice is discharged along the discharge pipe 3. This reduces the number of times the operator has to open the bin 1 to clean the rice powder. The operation is simple, time-saving and labor-saving, and improves maintenance efficiency.
