Description

Technical Field

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

[0002] Rice polishing is a common processing method that removes the outer husk from the rice grains, making them more glossy and visually appealing. Polished rice has a smoother, less coarse texture. Removing the husk reduces the grainy texture when chewing, making the rice softer and smoother. Polished rice absorbs water more easily and cooks faster. Removing the husk also allows water to penetrate the rice grain more readily, speeding up the cooking process.

[0003] A rice polishing machine is disclosed in announcement number CN218531023U, including a polishing cylinder, two upper polishing discs, an annular tube, two lower polishing discs and a blocking component. The two upper polishing discs are connected to the inside of the polishing cylinder and are arranged at an interval between the upper and lower parts. A water storage tank is opened inside the two upper polishing discs, and a number of water spray holes are connected between the water storage tank and the bottom wall of the upper polishing disc.

[0004] Existing rice polishing machines have the following drawbacks: they only use polishing components to polish the rice during polishing, which cannot reduce the heat generated by rice grain friction, maintain the quality and taste of the rice, reduce the breakage rate during the polishing process, and maintain the integrity and appearance of the rice.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a rice polishing device.

[0007] To solve the above problems, the technical solution of this utility model is: a rice polishing device, including a polishing barrel, wherein a rectangular cavity is provided at the top of the polishing barrel, and a feed inlet is provided at the top;

[0008] A pre-polished structure is disposed within a rectangular cavity;

[0009] A water storage tray is fixedly connected to the inside of the polishing barrel and located below the pre-polishing structure. The water storage tray has a water storage cavity inside and a water leakage hole at the bottom of the water storage cavity. A water inlet pipe is inserted through one side of the water storage tray, and a control valve is provided at one end of the water inlet pipe that extends out of the polishing barrel.

[0010] A polishing sieve is located below a water storage tray. The top outer ring of the polishing sieve is fitted with a polishing barrel. The interior of the polishing sieve is filled with a number of polishing balls. A vibration motor is fixedly connected to the bottom of the polishing sieve.

[0011] A fixing plate is fixedly connected to the inside of the polishing barrel and located below the water storage tray. Several springs are evenly distributed around the top of the fixing plate. Each spring has a matching telescopic rod inside. The top of the spring is fixedly connected to the bottom of the outer ring of the polishing screen.

[0012] A flow-retarding plate is provided below the polishing screen and is inclined.

[0013] A material conveying structure is located at the bottom of the polishing barrel;

[0014] A drying structure is located on top of the material conveying structure.

[0015] Furthermore, the pre-polishing structure includes two polishing rollers, which are rotatably connected within a rectangular cavity. Each of the two polishing rollers has a gear fixedly connected to one end, and the two gears are meshed together. A motor is fixedly connected to one end of one of the two polishing rollers away from the gear, and the motor is fixedly connected to the outside of the polishing barrel.

[0016] Furthermore, the highest point of the flow-retardant plate is fixedly connected to the wall of the polishing barrel, and a material leakage port is left between the lowest point and the barrel wall.

[0017] Furthermore, the material conveying structure includes a material conveying pipe, one end of which is fixedly connected to the bottom of the polishing barrel and communicates with the polishing barrel, and the other end of which has a discharge port. A rotating shaft is rotatably connected inside the material conveying pipe, one end of which is fixedly connected to a motor, and a spiral blade is fixedly connected to the outside of the rotating shaft.

[0018] Furthermore, the air-drying structure includes an installation frame, which is located at the top of the conveying pipe. The top and bottom of the installation frame are provided with protective nets, and an air-drying device is provided between the two protective nets. A heating device is provided at the top of the bottom protective net.

[0019] The advantages of this invention compared to existing technologies are as follows: the water inlet pipe connects to an external water source and enters the water storage pan, and the water mist generated by the atomizing nozzle comes into contact with the pre-polished rice. The vibration motor and spring work together to vibrate the polishing balls inside the polishing sieve and generate friction between them and the rice. Since the rice surface has a certain amount of moisture, the heat generated during the friction process can be reduced, thereby polishing the rice surface. The polishing balls are in a moving state inside the polishing sieve, so they will not excessively squeeze the rice and produce debris. Attached Figure Description

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0026] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0027] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] like Figures 1 to 4As shown, a rice polishing device includes a polishing barrel 1, a pre-polishing structure 3, a water storage tray 4, a polishing sieve 9, a fixing plate 12, a flow buffer plate 14, a conveying structure 15, and a drying structure 16. The polishing barrel 1 has a rectangular cavity at its top and a feed inlet 2 at the top. The pre-polishing structure 3 is located within the rectangular cavity. Rice to be polished is conveyed to the polishing barrel 1 through the feed inlet 2 for polishing. The rice undergoes pre-polishing treatment as it passes through the pre-polishing structure 3. The water storage tray 4 is fixedly connected to the inside of the polishing barrel 1 around its circumference and is located below the pre-polishing structure 3. The water storage tray 4 has a water storage cavity 5 inside. Atomizing nozzles 6 are provided at the bottom of the polishing tank 1. A water inlet pipe 7 is inserted through one side of the water storage tray 4. The water inlet pipe 7 extends out of the polishing tank 1 and has a control valve 8 inside. The polishing sieve 9 is located below the water storage tray 4. The water inlet pipe 7 is connected to an external water source and enters the water storage tray 4. The water mist generated by the atomizing nozzles 6 comes into contact with the pre-polished rice. The polishing sieve 9 is filled with several polishing balls 10. A vibration motor 11 is fixedly connected to the bottom of the polishing sieve 9. A fixing plate 12 is fixedly connected to the inside of the polishing tank 1 and is located below the water storage tray 4. Several springs 13 are evenly distributed around the top of the fixing plate 12. 3. An internally fitted telescopic rod is provided. The top of the spring 13 is fixedly connected to the bottom of the outer ring of the polishing sieve 9. The vibration motor 11, in conjunction with the spring 13, vibrates the polishing balls 10 inside the polishing sieve 9, generating friction between the balls and the rice, thus polishing the rice surface. The polishing balls 10 are in a moving state within the polishing sieve 9, preventing excessive compression and the generation of debris. Because the diameter of the polishing balls 10 is larger than the diameter of the mesh in the polishing sieve 9, and the mesh diameter is larger than the diameter of the rice, during the polishing process, when the rice sinks to the bottom of the polishing sieve 9, it will pass through the mesh of the polishing sieve 9. The polishing process is completed by allowing the rice to leak out. The slow-flow plate 14 is located below the polishing screen 9 and is inclined. After polishing, the rice falls onto the slow-flow plate 14. The highest point of the slow-flow plate 14 is fixedly connected to the wall of the polishing barrel 1, and the lowest point has a leakage port between it and the barrel wall. The slow-flow plate 14 slows down the falling speed of the rice. The conveying structure 15 is located at the bottom of the polishing barrel 1, and the drying structure 16 is located at the top of the conveying structure 15. The conveying structure 15 and the drying structure 16 work together to dry the rice during the process of conveying the rice to the outside, so as to facilitate and accelerate the subsequent drying effect of the rice.

[0029] The pre-polishing structure 3 includes two polishing rollers 301, which are rotatably connected in a rectangular cavity. Each polishing roller 301 has a gear 302 fixedly connected to one end, and the two gears 302 mesh with each other. A motor 303 is fixedly connected to one end of the polishing roller 301 away from the gear 302. The motor 303 is fixedly connected to the outside of the polishing barrel 1. The motor 303 drives the polishing roller 301 and the gear 302 at one end to rotate. While the two polishing rollers 301 are driven by the two gears 302, the rice is initially polished as it passes between the two polishing rollers 301. Since there is an appropriate distance between the two polishing rollers 301, the rice will not be excessively squeezed.

[0030] The conveying structure 15 includes a conveying pipe 1501. One end of the conveying pipe 1501 is fixedly connected to the bottom of the polishing barrel 1 and communicates with the polishing barrel 1. The other end has a discharge port 1502. A rotating shaft 1503 is rotatably connected inside the conveying pipe 1501. A motor 1504 is fixedly connected to one end of the rotating shaft 1503. A spiral blade 1505 is fixedly connected to the outside of the rotating shaft 1503. When the motor 1504 is started, it drives the rotating shaft 1503 and the spiral blade 1505 to rotate, thereby conveying the polished rice to the discharge port 1502. The bottom of the conveying pipe 1501 has an arc-shaped structure, so the conveying of rice can be more thorough.

[0031] The air-drying structure 16 includes a mounting frame 1601, which is located at the top of the conveying pipe 1501. Protective nets 1602 are provided at both the top and bottom of the mounting frame 1601. An air-drying device 1603 is located between the two protective nets 1602. A heating device is located at the top of the bottom protective net 1602. During the conveying of rice, the air-drying device 1603 is activated to blow air into the conveying pipe 1501. Combined with the heating device, the air entering the conveying pipe 1501 is heated, thereby accelerating the evaporation of moisture from the rice surface. Furthermore, the protective nets 1602 at the top and bottom of the mounting frame 1601 prevent impurities from the outside air from entering the conveying pipe 1501 and also prevent rice from entering the air-drying device 1603, thus avoiding any impact on its use.
