Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically to a purification device used in rice processing. Background Technology

[0002] However, the dust generated by the cleaning equipment used in rice processing is relatively large during actual use, and it is difficult to collect the dust effectively. Therefore, there are shortcomings and no measures are available to remove dust during equipment operation.

[0003] Chinese patent document (authorization announcement number: CN 221046643 U) discloses a rice processing impurity removal device. It includes a shell with a feed inlet on its upper surface. Impurity removal components are located on both sides of the inner wall of the shell. A cover plate is hinged to one end of the shell near the opening of the impurity removal components. A guide plate is located at the lower part of the shell to direct the flow of rice. A filter component is inserted into the opening at the lower part of the shell via a connector. In this rice processing impurity removal device, the rice is first filtered twice for fine impurities by the two impurity removal components. Then, the rice flows through the guide plate into the filter component, where it is filtered to remove light impurities and rice husks. This not only improves filtration efficiency but also facilitates the processing of the filtered impurities, enhancing the practicality of the impurity removal device and thus improving the quality of rice processing and economic benefits.

[0004] This type of processing and impurity removal equipment is relatively expensive, and its effectiveness in removing some solid particles from rice cannot be guaranteed. Summary of the Invention

The conveyor belt then carries the rice grains to the left. By using the magnet at the top of the box, some metal particles in the rice grains can be adsorbed and removed. Adding a magnetic separation component can further reduce impurities in the rice. Attached Figure Description

[0025] Specifically, such as Figure 1 and Figure 2 As shown, during the impurity removal operation, the exhaust fan 306 is activated, and the rice grains are then discharged from the discharge port 402 and introduced into the impurity removal box 101. During the falling process, the light dust and impurities contained inside the rice grains are extracted by the exhaust fan 306 and guided into the dust collection bag 303 through the mounting cylinder 305. After entering the dust collection bag 303, the dust and impurities are trapped, and the air is discharged outward. The dust collection bag 303 can be used to assist in the centralized collection of dust generated during the operation. By rotating the mounting ring seat 301 outward from the mounting ring opening 304 on the right side of the mounting cylinder 305, it can be quickly disassembled, and the collected dust and impurities inside can be emptied and cleaned.

[0026] The adjustment mechanism 5 is installed on the right side of the discharge port 402, including a slot 502 opened inside the right side of the discharge port 402 and an insert plate 501 inserted into the slot 502.

Specifically, such as Figure 1 and Figure 3 As shown, when feeding rice into the equipment, the opening of the discharge port 402 can be flexibly adjusted by using the electric push rod 504 to extend and retract, which facilitates the adjustment of the feeding amount and helps to remove impurities evenly from the rice.

Then, the conveyor belt 2 can drive the rice grains to the left. By using the internal top magnet 606, some metal particles contained in the rice grains can be adsorbed and removed. By increasing the magnetic separation component, impurities in the rice are further reduced.

[0030] When this impurity removal equipment performs impurity removal operations, the exhaust fan 306 is activated to draw air, and then the rice grains are discharged from the discharge port 402 and guided into the impurity removal box 101. During the falling process, the light dust and impurities contained in the rice grains can be extracted by the exhaust fan 306 and guided into the dust collection bag 303 through the mounting cylinder 305. After entering the dust collection bag 303, the dust and impurities are trapped, and the air is discharged outward. The dust collection bag 303 can be used to collect the dust generated during the operation. At the same time, when feeding rice into the equipment, the opening of the discharge port 402 can be flexibly adjusted by using the electric push rod 504 to extend and retract, thereby adjusting the feeding amount. In addition, after the rice grains are guided into the impurity removal box 101 for impurity removal, they fall onto the top of the conveyor belt 2. Then, the conveyor belt 2 can carry the rice grains to the left, and the magnet 606 at the top of the rice grains can be used to help adsorb and remove some metal particles contained in the rice grains.
