Description

Technical Field

[0001] This application relates to the field of rice processing technology, and in particular to a rice polishing machine. Background Technology

[0002] Rice polishing is a crucial step in rice processing, aiming to physically remove bran powder from the surface of rice grains and improve their smoothness and uniformity. Adding an appropriate amount of water during polishing significantly enhances the polishing effect. By weakening the binding force between the endosperm and the remaining bran, it helps to more thoroughly remove the bran, causing the starch on the rice surface to gelatinize and giving it an appealing shine.

[0003] However, in existing rice polishing machines, the water droplets sprayed by the water spraying mechanism do not make sufficient contact with the rice. Specifically, commonly used water spraying mechanisms typically employ simple spray heads or nozzles. Due to limitations in spray pressure and angle, the water droplets often fail to penetrate into the gaps between rice grains, failing to ensure that the water droplets evenly and fully cover the rice surface. As a result, insufficient water contact may lead to incomplete removal of bran powder from the rice and may also cause unnecessary damage to the rice, increasing the broken rice rate and affecting the product's quality and taste.

[0004] To address the aforementioned issues, a rice polishing machine is now designed. Utility Model Content

[0005] This application provides a rice polishing machine to solve the problem in the prior art where the water droplets sprayed by the water spraying mechanism of the existing rice polishing machine do not make sufficient contact with the rice, resulting in incomplete removal of bran powder from the rice and an increase in the broken rice rate.

[0006] Firstly, a rice polishing machine is provided, comprising:

[0007] A frame is provided with a support base, and an outer shell is provided inside the support base. A polishing cylinder is rotatably arranged inside the outer shell. Both ends of the polishing cylinder are in contact with the side walls at both ends of the outer shell. A polishing roller is rotatably arranged inside the polishing cylinder. A first driving component is provided on one side of the frame. One end of the first driving component is connected to the polishing cylinder and is used to drive the polishing cylinder to rotate. A second driving component is provided on the other side of the frame. The second driving component is connected to the polishing roller and is used to drive the polishing roller to rotate.

[0008] The support base is provided with a water spraying mechanism, which includes a spray plate disposed inside the outer shell and located above the polishing cylinder. The spray plate has a water storage cavity inside, and multiple atomizing nozzles are disposed at equal intervals at the bottom of the spray plate. The water spraying mechanism also includes a water supply end disposed above the support base, which is used to supply water to the water storage cavity.

[0009] In some embodiments, the support base is n-shaped, and the outer shell is cylindrical;

[0010] The outer casing has an opening, and a glass cover is hinged to the opening.

[0011] In some embodiments, the polishing cylinder includes a stainless steel filter cylinder rotatably disposed inside the outer shell. The stainless steel filter cylinder has open ends, a round cover is provided at one end of the stainless steel filter cylinder, a feed port is provided on the round cover, and multiple reinforcing ribs are provided on the stainless steel filter cylinder.

[0012] The stainless steel filter cylinder has one open end and the other end of the round cover respectively attached to the inner sidewalls of both ends of the outer shell.

[0013] In some embodiments, a feed hopper and a discharge hopper are respectively provided at both ends of the outer shell, the feed hopper is connected to the feed port on the round cover, and the opening of the feed hopper faces upward;

[0014] The discharge hopper is connected to one end of the opening of the stainless steel filter cylinder, and the opening of the discharge hopper faces downward.

[0015] A slag discharge valve is provided at the bottom of the outer shell.

[0016] In some embodiments, the spray plate is arc-shaped and located directly above the stainless steel filter cylinder, the atomizing nozzles are evenly distributed below the spray plate, and the atomizing nozzles are in communication with the spray plate.

[0017] In some embodiments, the water supply end includes a water tank disposed on a support base and a pump body disposed on the support base, wherein the pump body inlet is connected to the pump body and the pump body outlet is connected to the spray plate.

[0018] In some embodiments, the drive unit 1 includes a mounting platform 1 disposed on the frame, the mounting platform 1 being provided with a drive motor 1 and a reducer 1, the output shaft of the drive motor 1 being connected to the input shaft of the reducer 1, the output shaft of the reducer 1 being connected to the round cover, and being used to drive the stainless steel filter cylinder to rotate.

[0019] In some embodiments, the second drive component includes a second mounting platform disposed on the other side of the frame, and a second drive motor and a second reducer disposed on the second mounting platform. The output shaft of the second drive motor is connected to the input shaft of the second reducer, the output shaft of the second reducer is connected to one end of the polishing roller, and the other end of the polishing roller is rotatably connected to one side of the round cover.

[0020] In some embodiments, the inner side of the stainless steel filter cylinder is also provided with spiral blades, which are used to guide the rice to flow towards the end closer to the discharge hopper.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] This application provides a rice polishing machine that solves the problem in existing rice polishing machines where the water droplets sprayed by the water spraying mechanism do not make sufficient contact with the rice, resulting in incomplete removal of bran powder from the rice and an increased rate of broken rice.

[0033] Please see Figures 1-3 A rice polishing machine includes: a frame 1 with a support base 2 on it; a shell 3 inside the support base 2; a polishing cylinder 4 rotatably disposed inside the shell 3; both ends of the polishing cylinder 4 contacting the side walls at both ends of the shell 3; a polishing roller 5 rotatably disposed inside the polishing cylinder 4; a drive component 6 on one side of the frame 1, one end of which is connected to the polishing cylinder 4 and used to drive the polishing cylinder 4 to rotate; a drive component 7 on the other side of the frame 1, which is connected to the polishing roller 5 and used to drive the polishing roller 5 to rotate; a water spraying mechanism 8 on the support base 2, the water spraying mechanism 8 including a spray plate 81 disposed inside the shell 3 and above the polishing cylinder 4; a water storage cavity 82 inside the spray plate 81; multiple atomizing nozzles 83 evenly distributed at the bottom of the spray plate 81; and a water supply end 84 disposed above the support base 2, the water supply end 84 being used to supply water to the water storage cavity 82.

[0034] The polishing cylinder 4 is driven by drive component 6 to rotate stably inside the outer casing 3. Both ends of the polishing cylinder 4 are in close contact with the side walls of the outer casing 3, ensuring stability and sealing during rotation. Simultaneously, the polishing roller 5 rotates inside the polishing cylinder 4 driven by drive component 7. The surface of the polishing roller 5 has a specific texture to generate friction with the rice grains, achieving a polishing effect.

[0035] Meanwhile, the water supply end 84 continuously supplies water to the water storage chamber 82 inside the spray plate 81, ensuring a continuous water supply. The water in the water storage chamber 82 is evenly sprayed out through multiple atomizing nozzles 83 distributed at equal intervals, forming a fine water mist. This water mist comes into full contact with the rice particles during the polishing process, which moistens the rice and enhances the polishing effect. At the same time, the even distribution of the water mist also helps to avoid rice breakage caused by uneven moisture, thus improving the quality of the polished rice.

[0036] As the polishing cylinder 4 and polishing roller 5 rotate, the rice grains are subjected to friction by the polishing roller 5 inside the polishing cylinder 4, the surface bran powder is removed, and the surface of the rice becomes smooth.

[0037] The double rotation of the polishing cylinder 4 and the polishing roller 5 allows the rice grains to undergo more comprehensive friction during the polishing process, thereby improving polishing efficiency and quality. Furthermore, the fine water mist sprayed from the water supply end 84, the water storage chamber 82, and the atomizing nozzle 83 can make more thorough contact with the double-rotating rice, resulting in more even wetting of the rice grains and making the polished rice surface smoother and more uniform in color.

[0038] With the uniform spraying of water mist and the polishing action of polishing roller 5, the rice is subjected to more even water treatment during the polishing process, avoiding the phenomenon of broken rice caused by uneven water distribution.

[0039] In this embodiment, the support base 2 is n-shaped and the outer shell 3 is cylindrical; the outer shell 3 is provided with an opening, and a glass cover plate 31 is hinged to the opening.

[0040] The support base 2 is designed with an n-shaped structure, which provides sufficient stability and support. The two sides of the n-shaped structure can be regarded as support arms, which are connected by the top horizontal plate to form a stable base, effectively supporting the outer shell 3 and the internal polishing mechanism.

[0041] The outer shell 3 is cylindrical, which facilitates the loading and unloading of materials and the polishing process. The cylindrical outer shell 3 can evenly distribute the rotational force of the polishing cylinder 4 and the polishing roller 5, ensuring that the rice is subjected to uniform friction during the polishing process.

[0042] In addition, the outer casing 3 has an opening, and a glass cover 31 is hinged to the opening, so that the operator can easily observe the polishing process, such as the polishing effect of the rice, the operating status of the polishing cylinder and polishing roller, etc.

[0043] like Figure 2 , Figure 3 and Figure 6 In one embodiment, the polishing cylinder 4 includes a stainless steel filter cylinder 41 rotatably disposed inside the outer casing 3. The stainless steel filter cylinder 41 is open at both ends, and a round cover 42 is provided at one end of the stainless steel filter cylinder 41. A feed inlet 421 is provided on the round cover 42, and a plurality of reinforcing ribs 43 are provided on the stainless steel filter cylinder 41. The open end of the stainless steel filter cylinder 41 and the other side of the round cover 42 are respectively attached to the inner sidewalls at both ends of the outer casing 3.

[0044] The stainless steel filter cartridge 41 serves as the main body of the polishing cartridge 4, and its material selection of stainless steel ensures good corrosion resistance and durability.

[0045] The stainless steel filter cylinder 41 is open at both ends to facilitate material loading and unloading and the polishing process. One end is sealed by a round cap 42, which fits tightly with one end of the stainless steel filter cylinder 41 to ensure a tight seal during the polishing process. The feed inlet 421 on the round cap facilitates the smooth feeding of materials while preventing material leakage during polishing.

[0046] In order to enhance the structural strength of the stainless steel filter cylinder 41 and prevent it from deforming or breaking due to uneven stress during rotation, multiple reinforcing ribs 43 are specially provided. The reinforcing ribs 43 are evenly distributed on the outer wall of the stainless steel filter cylinder 41, which effectively improves its load-bearing capacity and service life.

[0047] The stainless steel filter cartridge 41 has one open end and the other end of the round cover 42 tightly fitted to the inner walls of both ends of the outer shell 3, ensuring the stability and sealing of the polishing cartridge during rotation and avoiding material leakage or reduced polishing effect.

[0048] The fine mesh of the stainless steel filter cartridge 41 helps to evenly distribute the polishing medium and moisture, allowing the rice grains to experience more uniform friction during the polishing process. This not only improves polishing efficiency but also results in a smoother surface and more uniform color of the polished rice. Additionally, it facilitates the removal of rice bran.

[0049] like Figure 2 and Figure 3 As shown, it should be noted that in this embodiment, the outer shell 3 is provided with a feed hopper 9 and a discharge hopper 10 at its two ends, respectively. The feed hopper 9 is connected to the feed inlet 421 on the round cover 42, and the opening of the feed hopper 9 faces upward; the discharge hopper 10 is connected to one end of the opening of the stainless steel filter cylinder 41, and the opening of the discharge hopper 10 faces downward; a slag discharge valve 12 is provided at the bottom of the outer shell 3. The feed hopper 9 is located above the end of the outer shell 3, and the discharge hopper 10 is located below the end of the outer shell 3, which is conducive to the inflow and outflow of materials.

[0050] The feed hopper 9 is located above one end of the outer casing 3 and is connected to the feed port 421 on the round cover 42, allowing materials such as rice to be easily fed into the polishing cylinder 4 through the feed hopper 9. The opening of the feed hopper 9 faces upward, facilitating feeding operations by operators or connection to an external elevator, thus improving the accuracy and efficiency of feeding.

[0051] The discharge hopper 10 is located below the other end of the outer shell 3 and is connected to the opening end of the stainless steel filter cylinder 41, so that the polished rice can be smoothly discharged from the inside of the polishing cylinder 4, avoiding blockage and accumulation of materials during the discharge process.

[0052] The opening of the discharge hopper 10 faces downwards, which makes it easier for operators to collect the polished rice and also improves the accuracy and efficiency of the discharge.

[0053] The slag discharge valve 12 is located at the bottom of the outer shell 3 and is used to discharge impurities such as broken rice and bran powder generated during the polishing process. This not only ensures the cleanliness and hygiene of the inside of the polishing cylinder 4, but also avoids the impact of impurities on the polishing effect.

[0054] like Figure 2 and Figure 5 As shown, specifically, the spray plate 81 is arc-shaped and located directly above the stainless steel filter cylinder 41. The atomizing nozzles 83 are evenly distributed below the spray plate 81, and the atomizing nozzles 83 are interconnected with the spray plate 81.

[0055] The spray plate 81 is designed to be arc-shaped. This shape is to better adapt to the cylindrical structure of the stainless steel filter cylinder 41. The arc-shaped spray plate 81 can ensure that water can be evenly covered on the stainless steel filter cylinder 41 when spraying, thereby improving the uniformity of the polishing effect.

[0056] Atomizing nozzles 83 are evenly distributed below the spray plate 81 and are interconnected with the spray plate, ensuring that water can be sprayed evenly onto the rice and other materials inside the stainless steel filter cartridge 41 in the form of fine droplets. The atomized water can not only penetrate into the material better, but also reduce water waste and accumulation, thereby further improving polishing efficiency and quality.

[0057] like Figure 2 and 3 As shown, in one embodiment, the water supply end 84 includes a water tank 841 disposed on the support base 2 and a pump body 842 disposed on the support base 2. The water inlet of the pump body 842 is connected to the pump body 842, and the water outlet of the pump body 842 is connected to the spray plate 81.

[0058] Water tank 841 is used to store the water required during the polishing process. It is also equipped with a water level indicator and a water inlet, allowing operators to monitor the water level and replenish it as needed.

[0059] Pump body 842 is also mounted on support base 2 to facilitate water extraction and transmission. The inlet of pump body 842 is connected to water tank 841, and water supply is achieved by extracting water from water tank 841. The outlet of pump body 842 is connected to spray plate 81, and the extracted water is delivered to the water storage chamber inside spray plate 81 at a certain pressure and flow rate, and then sprayed onto rice in the form of droplets through atomizing nozzle 83.

[0060] like Figure 3As shown, the drive unit 6 in this embodiment includes a mounting platform 61 mounted on the frame 1. The mounting platform 61 is equipped with a drive motor and a reducer. The output shaft of the drive motor is connected to the input shaft of the reducer. The output shaft of the reducer is connected to the round cover 42 and is used to drive the stainless steel filter cylinder 41 to rotate.

[0061] Mounting platform 61 serves as the mounting base for drive motor 1 and reducer 1.

[0062] The drive motor, serving as the power source for the rotation of the polishing cylinder, is selected to meet the working requirements of the polishing machine, providing sufficient torque and speed to drive the rotation of the polishing cylinder. The drive motor is also equipped with an electrical control system to realize functions such as motor start, stop, and speed regulation.

[0063] The output shaft of drive motor one is connected to the input shaft of reducer one through a coupling to ensure their coaxiality and transmission efficiency.

[0064] The function of the speed reducer is to reduce the output speed of the motor and increase the torque in order to meet the mechanical requirements when the polishing barrel rotates.

[0065] The output shaft of reducer 1 is connected to the round cover 42 and fixed together with bolts and fasteners. When drive motor 1 starts, reducer 1 reduces the output speed of drive motor 1 and increases torque to drive the round cover 42 and stainless steel filter cartridge 41 to rotate.

[0066] like Figure 3 As shown, in addition, the driving component 7 described in this embodiment includes a mounting platform 71 on the other side of the frame 1, and a driving motor 2 and a reducer 2 on the mounting platform 71. The output shaft of the driving motor 2 is connected to the input shaft of the reducer 2. The output shaft of the reducer 2 is connected to one end of the polishing roller 5. The other end of the polishing roller 5 is rotatably connected to one side of the round cover 42.

[0067] Drive motor two is mounted on mounting platform two 71, serving as the power source for the rotation of the polishing roller. Its selection also meets the working requirements of the polishing machine, providing sufficient torque and speed to drive the rotation of the polishing roller. Drive motor two is also equipped with an electrical control system for starting, stopping, and speed regulation of the motor.

[0068] The function of the second reducer is also to reduce the output speed of the motor and increase the torque to meet the mechanical requirements of the polishing roller rotation. The output shaft of the second drive motor and the input shaft of the second reducer are connected by a coupling to ensure their coaxiality and transmission efficiency.

[0069] The output shaft of reducer 2 is connected to one end of polishing roller 5 and fixed together with fasteners. The other end of polishing roller 5 is rotatably connected to one side of round cover 42 to ensure that polishing roller can rotate smoothly around its axis. When drive motor 2 rotates, reducer 2 adjusts the output speed of the motor and increases the torque, thereby driving polishing roller 5 to rotate.

[0070] like Figure 3 and Figure 4 As shown, preferably, the stainless steel filter cylinder 41 in this embodiment is further provided with a spiral blade 11 on its inner side, the spiral blade 11 being used to guide the rice to flow towards the end near the discharge hopper 10.

[0071] The spiral blades 11 are installed on the inner wall of the stainless steel filter cylinder 41, extending along the axial direction of the cylinder and arranged in a spiral shape that gradually approaches one end of the discharge hopper 10. This arrangement ensures that when the polishing cylinder rotates, the spiral blades can effectively guide materials such as rice to flow along a specific path.

[0072] The spiral blades 11 make the flow of rice within the polishing drum more orderly and efficient. As the polishing drum rotates, the spiral blades can push the material along the spiral path gradually closer to the discharge hopper, thereby avoiding material accumulation and blockage.
