Description

Technical Field

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

[0002] Organic rice refers to rice grown using natural and organic farming methods. Organic rice must be a high-quality rice variety recommended by the crop improvement station, and chemical fertilizers, pesticides, and growth regulators cannot be used during cultivation. Rice cereal made from organic rice is a complementary food for infants, which can help the casein in milk powder form loose and soft curds, making it easier to digest and absorb.

[0003] During production and processing, rice needs to be ground. However, rice can easily accumulate on the surface of the grinding tank or grinding blocks during the grinding process, and failure to clean it in time can affect food safety. Therefore, we propose a fine grinding device for organic rice processing. Utility Model Content

[0004] The purpose of this invention is to provide a fine grinding device for organic rice processing. By uniformly arranging multiple nozzles above the inside of the grinding tank and facing the grinding block, compressed air can be sprayed downward from the nozzles when the machine stops after a batch of grinding. The airflow passes between the grinding tank and the grinding block, thereby cleaning the surface of the grinding tank and the grinding block, avoiding pollution caused by residual rice flour, and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fine grinding device for organic rice processing, comprising a grinding tank, a trough, and a grinding block. The trough is fixed in a lower position within the grinding tank, and a grinding groove, narrower at the top and wider at the bottom, is formed in the trough. The grinding block is rotatably mounted at the bottom of the grinding tank and placed in the grinding groove from below. The distance between the grinding block and the grinding groove gradually decreases from top to bottom. The grinding block is connected to a motor installed at the bottom of the grinding tank. A hopper is provided above the grinding tank, and a feed pipe is connected to the bottom of the hopper, penetrating into the interior of the grinding tank and positioned directly above the grinding groove. Multiple discharge pipes communicating with the interior are provided on the outer ring of the bottom of the grinding tank. A protrusion is provided above the inner ring of the grinding groove, and multiple spray pipes are evenly arranged on the bottom surface of the protrusion, facing the grinding groove and the grinding block. The spray pipes are connected to an annular cavity in the outer ring trough through an air passage, and the annular cavity is connected to an air pipe on the side of the grinding tank through a channel.

[0006] By adopting the above technical solution, after the rice is finely ground, an air jet is sprayed between the grinding tank and the grinding block using a nozzle. The airflow cleans away the rice flour residue on the surface of both, thus ensuring a clean state after each grinding and preventing food safety issues.

[0007] Optionally, an electric actuator is installed on the upper surface of the grinding tank directly above the grinding tank, and a sealing plate placed above the grinding tank is fixed to the end of the electric actuator.

[0008] By adopting the above technical solution, during air blowing cleaning, the top of the grinding tank can be blocked by a sealing plate, so that the airflow only blows downwards.

[0009] Optionally, the hopper is rotatably connected above the grinding tank via a bushing, and the rotation of the hopper will drive the feed pipe to rotate together.

[0010] By adopting the above technical solution, when the sealing plate is lowered, the feed pipe is moved away during rotation, thus avoiding the feed pipe affecting the lowering height of the sealing plate.

[0011] Optionally, a ring cover is fixed to the bottom surface of the grinding jar below the grinding block. The ring cover is a frustoconical shape that is narrower at the top and wider at the bottom.

[0012] By adopting the above technical solution, the ring cover has the function of guiding the ground rice flour to the outside so that it can be discharged from the discharge pipe.

[0013] Optionally, the outer surface of the hopper is provided with a vertical marking line, and only one marking line is provided.

[0014] By adopting the above technical solution, the position of the feed pipe can be easily determined by the marking line, and the position of the feed pipe can be accurately adjusted by rotating the hopper.

[0015] Optionally, the outer ring of the grinding jar is vertically supported by multiple feet.

[0016] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0017] 1. The technical solution of this application has multiple nozzles evenly arranged inside the grinding tank and facing the grinding tank and grinding blocks. When the machine stops after a batch of grinding, compressed air can be sprayed downward from the nozzles. The airflow passes between the grinding tank and grinding blocks to clean the surface of the grinding tank and grinding blocks, thus avoiding pollution caused by residual rice flour.

[0018] 2. The technical solution of this application sets a liftable sealing plate directly above the grinding tank. During air cleaning, the feed pipe can be rotated to move away from above the grinding tank, and the sealing plate can be used to block the top of the grinding tank, ensuring that the airflow will only flow downwards to guarantee the cleaning effect.

[0023] Please see Figure 1-2 This utility model provides a technical solution: a fine grinding device for processing organic rice, including a grinding tank 1, a trough 2 and a grinding block 3. The outer ring of the grinding tank 1 is vertically supported by multiple legs to achieve stable support for the grinding tank 1.

[0024] The trough block 2 is fixed in the lower part of the grinding tank 1, and the trough block 2 has a grinding groove 21 that runs vertically through the tank and is narrower at the top and wider at the bottom. The grinding block 3 is rotatably installed at the bottom of the grinding tank 1 and is placed in the grinding groove 21 from below. The distance between the grinding block 3 and the grinding groove 21 gradually decreases from top to bottom. The grinding block 3 is connected to the motor 31 installed at the bottom of the grinding tank 1. The outer surface of the grinding block 3 and the inner surface of the grinding groove 21 are rough grinding surfaces. When rice is placed between the grinding block 3 and the grinding groove 21, the grinding block 3 is driven to rotate by the motor 31, thereby grinding the rice. Finally, the grinding residue can be discharged downward between the two.

[0025] A hopper 4 is provided above the grinding tank 1. The bottom of the hopper 4 is connected to a feed pipe 41 that penetrates into the interior of the grinding tank 1 and is positioned directly above the grinding trough 21. The organic rice to be ground is fed into the hopper 4 and falls into the grinding trough 21 through the feed pipe 41 to be ground. In addition, the bottom outer ring of the grinding tank 1 is provided with multiple discharge pipes 12 that communicate with its interior. A ring cover 11 is fixed on the bottom surface of the grinding tank 1 below the grinding block 3. The ring cover 11 is a truncated cone shape that is narrow at the top and wide at the bottom. The rice flour can be guided by the ring cover 11 and finally discharged from the discharge pipe 12.

[0026] To facilitate cleaning of residual rice flour in the gaps between the grinding tank and grinding block 3 after grinding, a protrusion 22 is provided above the inner ring of the grinding tank 21. Multiple nozzles 221 are evenly arranged on the bottom surface of the protrusion 22, facing the space between the grinding tank 21 and the grinding block 3. The nozzles 221 are positioned below the protrusion 22 to prevent leakage and contact with the rice to be ground. The nozzles 221 are connected to the annular cavity 23 in the outer ring of the grinding tank 2 through the air passage 231. The annular cavity 23 is connected to the air pipe 232 on the side of the grinding tank 1 through the channel. An electrically controlled valve is also installed on the air pipe 232. During use, the air pipe 232 is connected to a compressed air source. After the rice grinding is stopped, the electrically controlled valve on the air pipe 232 is opened, and compressed air enters the annular cavity 23. It is then guided from the air pipe 232 to the nozzles 221 and sprayed downwards. The airflow blows downwards and acts between the grinding block 3 and the grinding tank 21 to remove and clean the residual rice flour, which is finally discharged from the discharge pipe 12.

[0027] In addition to using compressed air for cleaning, the compressed air can also be replaced with clean water, which can directly rinse the surfaces of the grinding tank 21 and the grinding block 3, resulting in a better cleaning effect.

[0028] When using compressed air for cleaning, since the area above the grinding tank 21 is also open, the airflow tends to flow upwards, affecting the cleaning effect. In this application, an electric push rod 5 is installed on the upper surface of the grinding tank 1 directly above the grinding tank 21, and the end of the electric push rod 5 is fixed with a sealing plate 51 placed above the grinding tank 21. In addition, the hopper 4 is rotatably connected to the upper part of the grinding tank 1 through a bushing. When the hopper 4 rotates, it will drive the feed pipe 41 to rotate together. Therefore, during cleaning, the hopper 4 and the feed pipe 41 can be rotated first to make the feed pipe 41 rotate and move away from the top of the grinding tank 21. Then, the electric push rod 5 can be controlled to drive the sealing plate 51 to lower the height and block the top of the grinding tank 21, so that the airflow only flows downwards, ensuring the cleaning effect of blowing.

[0029] The outer surface of the hopper 4 is vertically marked with a marking line 42. Only one marking line 42 is provided to facilitate the determination of the position of the feed pipe 41 during rotation, making it easy to adjust the rotation.

[0030] In operation, the compressed air source is connected to the air pipe 232, connecting the electrically controlled valve, electric actuator 5, and motor 31 on the air pipe 232 to the control equipment. Starting the motor 31 drives the grinding blocks 3 to rotate inside the grinding trough 21. Rice to be ground is fed into the hopper 4 and enters the grinding trough 21 through the feed pipe 41. The rice slowly falls between the grinding blocks 3 and the grinding trough 21, where it is finely ground by the interaction of the grinding blocks 3 and the grinding trough 21. The resulting rice flour is guided outwards by the ring cover 11 and finally discharged from the discharge pipe 12. After a batch of rice is ground and the machine is stopped, the hopper 4 and the feed pipe 41 are rotated first, causing the feed pipe 41 to rotate and feed the rice from the grinding trough 21. After the top of the grinding tank 21 is moved away, the electric actuator 5 can be controlled to lower the sealing plate 51 to block the top of the grinding tank 21. Then, the electric control valve on the air pipe 232 is opened, and compressed air enters the annular cavity 23. It is guided from the air pipe 232 to the nozzle 221 and sprayed downwards. Since the top of the grinding tank 21 is blocked, the airflow can only blow downwards and act between the grinding block 3 and the grinding tank 21 to remove and clean the residual rice flour. Finally, it is discharged from the discharge pipe 12. After cleaning, the electric control valve on the air pipe 232 is closed. The electric actuator 5 can be used again to raise the sealing plate 51 and rotate the hopper 4 and the feed pipe 41 so that the feed pipe 41 is placed above the grinding tank 21 again.
