Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rice processing technology, and in particular relates to a grinding device for processing selenium-enriched rice. Background Technology
[0002] Selenium-enriched rice is produced by supplementing rice with selenium during cultivation, resulting in rice rich in selenium. It is a functional agricultural product. Selenium can enhance the body's immunity, promote the proliferation of lymphocytes and the synthesis of antibodies and immunoglobulins. At the same time, selenium can reduce and alleviate the toxicity of heavy metals. Therefore, scientists call selenium the "king of anti-cancer elements" among trace elements, making selenium-enriched rice even more nutritious.
[0003] During processing, the same grinding equipment is often used for repeated grinding, which makes it impossible to quickly grind the selenium-enriched rice in multiple stages according to the needs during use. This results in low fineness of the powder, affecting the taste and quality of the rice noodles. Utility Model Content
[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:
[0005] A grinding device for processing selenium-enriched rice includes a grinding box, a first grinding block, and a second grinding disc. The grinding box contains a first grinding disc, a fixed rod, and a driving component. The first grinding block is located inside the first grinding disc and is connected to the driving component. A screen and a connecting rod are fixedly connected to the top of the second grinding disc. The connecting rod is fixedly connected to the first grinding block. One end of the fixed rod is fixedly connected to a second grinding block, which is located above the second grinding disc.
[0006] As a preferred embodiment of the above technical solution, a feed hopper is fixedly installed on the top of the grinding box, and a detachable receiving box is installed on the bottom.
[0007] As a preferred embodiment of the above technical solution, the driving component includes a motor, which is fixedly connected to a mounting base. The mounting base is installed on the outer wall of the grinding chamber, and the output end of the motor is fixedly connected to a transmission shaft. The end of the transmission shaft away from the motor passes through the grinding chamber and is fixedly connected to the first grinding block.
[0008] As a preferred embodiment of the above technical solution, a plurality of crossbeams are fixedly connected to the side wall of the first grinding block, and a blade is fixedly connected to the end of the crossbeam away from the first grinding block.
[0009] The beneficial effects of this utility model are as follows:
[0010] 1. This utility model uses a drive component to rotate the first grinding block, which grinds the selenium-enriched rice located between the first grinding block and the first grinding disc. The connecting rod drives the second grinding disc to rotate, and the second grinding block grinds the selenium-enriched rice falling on the second grinding disc a second time. The qualified powder passes through the screen by centrifugal force, while the unqualified powder continues to be ground by the second grinding disc and the second grinding block, ensuring that the fineness of the powder is consistent and improving the taste and quality of the rice noodles.
[0011] 2. During the rotation of the first grinding block of this utility model, the blades will be driven to rotate by the crossbeam. Since the end of the crossbeam extends to the outside of the screen, the airflow generated during the rotation of the blades will blow the selenium-rich rice flour adhering to the inner wall of the grinding box into the inside of the receiving box, thus avoiding waste.

[0016] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0017] Example
[0018] like Figure 1 and Figure 2 As shown, the grinding device for processing selenium-enriched rice includes a grinding box 10, a first grinding block 20, and a second grinding disc 30. The grinding box 10 is fixedly installed with a first grinding disc 11, a fixing rod 33, and a driving component. The first grinding block 20 is disposed inside the first grinding disc 11 and is connected to the driving component. The top of the second grinding disc 30 is fixedly connected with a screen 31 and a connecting rod 32. The connecting rod 32 is fixedly connected to the first grinding block 20. One end of the fixing rod 33 is fixedly connected to a second grinding block 34, which is located above the second grinding disc 30.
[0019] It should be noted that the gap between the first grinding block 20 and the first grinding disc 11 is greater than the gap between the second grinding disc 30 and the second grinding block 34, thereby achieving the purpose of graded grinding.
[0020] Specifically, the first grinding block 20 is rotated by the drive component to grind the selenium-enriched rice located between the first grinding block 20 and the first grinding disc 11. During the rotation of the first grinding block 20, the second grinding disc 30 is rotated by the connecting rod 32. The second grinding block 34 grinds the selenium-enriched rice that falls on the second grinding disc 30 a second time. The qualified powder passes through the screen 31 by centrifugal force, while the unqualified powder continues to be ground by the second grinding disc 30 and the second grinding block 34, ensuring that the fineness of the powder is consistent and improving the taste and quality of the rice noodles.
[0021] like Figure 1 As shown, a feed hopper 13 is fixedly installed on the top of the grinding box 10, and a detachable receiving box 12 is installed on the bottom.
[0022] It should be noted that the selenium-enriched rice enters the grinding box 10 from the feed hopper 13 and finally falls between the first grinding disc 11 and the first grinding block 20. The selenium-enriched rice powder that is finally screened by the screen 31 will fall into the collection box 12 for collection.
[0023] like Figure 1 As shown, the driving component includes a motor 22, which is fixedly connected to a mounting base 21. The mounting base 21 is installed on the outer wall of the grinding chamber 10, and the output end of the motor 22 is fixedly connected to a transmission shaft 23. The end of the transmission shaft 23 away from the motor 22 passes through the grinding chamber 10 and is fixedly connected to the first grinding block 20.
[0024] Specifically, the motor 22 drives the transmission shaft 23 to rotate. The transmission shaft 23 is concentrically set with the first grinding block 20, which can drive the first grinding block 20 to rotate stably within the first grinding disc 11.
[0025] like Figure 1 and Figure 2 As shown, several crossbeams 40 are fixedly connected to the side wall of the first grinding block 20, and blades 41 are fixedly connected to the end of the crossbeams 40 away from the first grinding block 20.
[0026] Specifically, during the rotation of the first grinding block 20, the blades 41 will be driven to rotate by the crossbeam 40. Since the end of the crossbeam 40 extends to the outside of the screen 31, the airflow generated by the blades 41 during rotation will blow the selenium-rich rice flour adhering to the inner wall of the grinding box 10 into the inside of the receiving box 12, thus avoiding waste.
[0027] Working principle: Selenium-enriched rice enters the grinding chamber 10 from the feed hopper 13 and finally falls between the first grinding disc 11 and the first grinding block 20. The motor 22 is started, driving the transmission shaft 23 to rotate. The transmission shaft 23 is concentrically positioned with the first grinding block 20, allowing the first grinding block 20 to rotate stably within the first grinding disc 11, grinding the selenium-enriched rice located between the first grinding block 20 and the first grinding disc 11 once. The rice then falls above the second grinding disc 30. During the rotation of the first grinding block 20, the connecting rod 32 drives the second grinding disc 30 to rotate, and the second grinding block 34 grinds the rice falling onto the second grinding disc 30. The selenium-enriched rice is ground a second time above the grinding disc 30. The qualified powder passes through the screen 31 by centrifugal force and falls into the collection box 12 for collection. The unqualified powder continues to be ground by the second grinding disc 30 and the second grinding block 34 to ensure consistent fineness and improve the taste and quality of the rice noodles. During the rotation of the first grinding block 20, the blades 41 are driven to rotate by the crossbeam 40. Since the end of the crossbeam 40 extends to the outside of the screen 31, the airflow generated by the blades 41 during rotation will blow the selenium-enriched rice powder attached to the inner wall of the grinding box 10 into the collection box 12 to avoid waste.
[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
