Description

Technical Field

[0001] This utility model relates to the field of rice processing technology, and in particular to a device for removing rice bran powder. Background Technology

[0002] During rice processing, after hulling and peeling, a small amount of bran powder remains on the surface of the rice grains. Normally, refined white rice should have a smooth and delicate surface, reflecting a soft sheen under light, giving it a clean and full visual appearance. However, when bran powder adheres to the surface of the rice grains, it forms a fine "powder film," not only making the rice grains feel rough but also scattering light, making the overall color of the rice grains appear dull and dark, losing its natural translucency. Bran powder itself contains a certain amount of fat and moisture, which, when attached to the surface of the rice grains, become a breeding ground for microorganisms. In terms of the eating experience, bran powder has a more direct impact on the taste of the rice. When rice with bran powder is cooked, these tiny fragments disperse in the water, making the rice soup cloudy. Therefore, bran powder needs to be removed during rice processing.

[0003] In existing technologies, rice is sieved through a fixed filter screen. During the conveying process, the rice is prone to accumulating and forming dead corners, which prevents the bran powder from making sufficient contact with the filter screen. A large amount of bran powder is discharged with the rice grains, resulting in low removal efficiency. Even when using a blowing device, the airflow direction is often unidirectional, which can only remove a small amount of bran powder on the surface and cannot reach the residual impurities between the rice grains, resulting in incomplete removal of bran powder. Therefore, we propose a bran powder removal device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for removing rice bran powder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rice bran removal device includes a hopper, an outer frame fixedly connected to the bottom of the hopper, a mesh frame fixedly connected inside the outer frame, a feed pipe fixedly communicating between the hopper and the mesh frame, an end ring fixedly connected inside the outer frame, an annular end plate rotatably sleeved on the outer wall of the end ring, an annular filter screen fixedly connected to the outer wall of the annular end plate, a circular plate fixedly connected to one end of the annular filter screen, a plurality of dispersing plates fixedly connected between the circular plate and the annular end plate, a collecting assembly provided on the outer wall of the outer frame, a circular frame fixedly connected to the outer wall of the outer frame, a motor fixedly connected inside the circular frame, and one end of the motor output shaft fixedly connected to the outer wall of the circular plate.

[0007] Preferably, the collection assembly includes a filter box, and the outer wall of the outer frame is fixedly connected to a first suction pipe and two second suction pipes. One end of the first suction pipe and the two second suction pipes are fixedly connected to the outer wall of the filter box. A filter plate is fixedly connected inside the filter box. The bran powder is collected by setting the collection assembly.

[0008] Preferably, a discharge pipe is fixedly connected to the bottom of the mesh frame, and one end of the discharge pipe is fixedly connected to the inner wall of the outer frame, so that rice can be discharged by setting the discharge pipe.

[0009] Preferably, the outer wall of the filter box is fixedly connected to a connecting pipe, and a blower is fixedly connected to one end of the connecting pipe. The blower generates negative pressure in the first and second exhaust pipes through the connecting pipe.

[0010] Preferably, the outer wall of the outer frame has a circular hole, and the inner wall of the circular hole is rotatably connected to the outer wall of the motor output shaft.

[0011] Preferably, the outer wall of the circular plate is slidably connected to the inner wall of the outer frame.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution uses a motor to drive the annular filter to rotate, and the annular filter works in conjunction with a fixed mesh frame. Together with a silicone dispersion plate, it thoroughly disperses the rice, avoiding the cleaning dead spots caused by rice accumulation in traditional fixed filters.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1-3 As shown, a device for removing rice bran powder is disclosed, comprising a hopper 1, an outer frame 2 fixedly connected to the bottom of the hopper 1, a mesh frame 3 fixedly connected to the inside of the outer frame 2, a feeding pipe 4 fixedly connected between the hopper 1 and the mesh frame 3, a discharge pipe 5 fixedly connected to the bottom of the mesh frame 3, one end of the discharge pipe 5 being fixedly connected to the inner wall of the outer frame 2, an end ring 6 fixedly connected to the inside of the outer frame 2, and an annular end plate 7 rotatably sleeved on the outer wall of the end ring 6, the end ring 6 serving to limit and support the annular end plate 7.

[0021] An annular filter screen 8 is fixedly connected to the outer wall of the annular end plate 7. The mesh frame 3 and the annular filter screen 8 work together to form a double filtration structure. The pore size of both is the same and smaller than the width of the rice, which can effectively block the rice from passing through and ensure that the rice is fully treated to remove the bran in the cavity.

[0022] One end of the annular filter screen 8 is fixedly connected to a circular plate 9. The outer wall of the circular plate 9 is slidably connected to the inner wall of the outer frame 2. Multiple dispersing plates 10 are fixedly connected between the circular plate 9 and the annular end plate 7. The dispersing plates 10 are made of silicone. When the annular filter screen 8 rotates, it can effectively disperse the rice falling into the cavity to prevent the rice from piling up. At the same time, the silicone material is soft and can minimize the impact damage to the rice and prevent the rice grains from breaking.

[0023] A circular frame 16 is fixedly connected to the outer wall of the outer frame 2. Multiple heat dissipation holes are provided on the outer wall of the circular frame 16. A motor 17 is fixedly connected inside the circular frame 16. One end of the output shaft of the motor 17 is fixedly connected to the outer wall of the circular plate 9. A circular hole is provided on the outer wall of the outer frame 2. The inner wall of the circular hole is rotatably connected to the outer wall of the output shaft of the motor 17.

[0024] The outer wall of the outer frame 2 is provided with a collection component, which includes a filter box 13. The outer wall of the outer frame 2 is fixedly connected to a first suction pipe 11 and two second suction pipes 12. The first suction pipe 11 can extract air to the inner area of ​​the mesh frame 3, while the second suction pipes 12 act on the space between the outer frame 2 and the annular filter screen 8. The dual suction can capture the dispersed bran powder from all directions. One end of the first suction pipe 11 and the two second suction pipes 12 are fixedly connected to the outer wall of the filter box 13.

[0025] A connecting pipe 14 is fixedly connected to the outer wall of the filter box 13, and a blower is fixedly connected to one end of the connecting pipe 14. A filter plate 15 is fixedly connected inside the filter box 13. The filter plate 15 can filter the airflow containing bran powder entering the filter box 13 and effectively intercept the bran powder.

[0026] Working principle: In operation, rice is conveyed into hopper 1 via an existing conveyor. The rice then enters discharge pipe 4 from hopper 1, and from discharge pipe 4 into the cavity between mesh frame 3 and annular filter screen 8. The mesh frame 3 and annular filter screen 8 have the same aperture, which is smaller than the width of the rice. As motor 17 rotates, it drives circular plate 9 to rotate. The rotation of circular plate 9 drives annular filter screen 8 and annular end plate 7 to rotate, thereby driving multiple dispersing plates 10 to rotate. The rice falling into the cavity is then discharged sequentially from discharge pipe 5. During the discharge process, the rice is dispersed along with the rotation of the multiple dispersing plates 10. The rice is dispersed by the action of the blower. As the blower operates, the rice bran powder passes through the connecting pipe 14 at the input end and enters the first exhaust pipe 11 and the second exhaust pipe 12 through the annular filter screen 8 and the mesh frame 3. The rice bran powder is removed by the two negative pressure exhaust systems. The rice bran powder enters the filter box 13 and is filtered by the filter plate 15. The purified air is then discharged from the outlet of the blower. The filter plate 15 can be replaced by opening the filter box 13 periodically. The filter parts of the annular filter screen 8 and the mesh frame 3 are made of nylon, and the dispersing plate 10 is made of silicone to prevent the rice from breaking during rotation.

[0027] It should be noted that when actually put into use, an existing PLC controller can be added. The PLC controller is electrically connected to the motor 17 and the blower to facilitate the control of the overall operation.
