Description

Technical Field

[0001] The invention belongs to the technical field of food processing, and in particular relates to an automatic rice grinding machine and a rice processing method. Background Art

[0002] Rice is a food made from paddy rice after processes such as cleaning, husking, milling, and finished product arrangement. It is one of the most common foods in people's lives. After years of development, many accessory foods with it as raw materials have been derived, such as rice noodles, rice cakes, etc., and most of these derivatives require rice to be ground into powder and then put into use. The traditional grinding method is to use a grinding wheel for manual grinding. With the development of science and technology, there is no need for manual push when turning the grinding wheel, and mechanical equipment is used instead. Therefore, automatic rice grinding machines have come into being.

[0003] For example, a rice grinding system for puffed food processing disclosed in Chinese patent application CN109382168A lacks a corresponding screening mechanism when grinding rice. Unqualified particles are inevitable in the rice grinding process, and a separate screening mechanism needs to be set up later for screening work. In addition, the mass of the milling disc used for grinding rice will not be too small, and the mechanical equipment that assists the rotation of the milling disc will generally not shake continuously. Moreover, in this device, rice particles are pre-placed, and the grinding area is between the milling discs. During the grinding process, feeding operations cannot be performed. After each grinding, the equipment needs to be adjusted to clean the falling area, and it is inevitable that the equipment needs to be started and stopped frequently, which will undoubtedly increase equipment loss. Summary of the invention

[0051] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0053] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0054] like Figure 1-7 As shown, the present invention provides an automatic rice grinding machine, including a support base 1, a fixed disk 2 is fixedly mounted above the support base 1, a rolling disk 3 is mounted above the fixed disk 2, a circulating feeding module 4 is arranged on the outer side of the support base 1, the circulating feeding module 4 is used to transport the rice particles that are not completely crushed to the top of the rolling disk 3, a screening module 5 is arranged on the inner side of the circulating feeding module 4, and the screening module 5 is arranged on the outer side of the fixed disk 2, and is used to screen the rice particles that are not completely crushed, an air supply module 6 is arranged below the support base 1, and the air supply module 6 is used to blow the rice powder crushed in the screening module 5, and a pre-crushing module 7 is arranged inside the rolling disk 3, and the pre-crushing module 7 is used to pre-crush the complete rice particles, including a fixed disk 2 and a pre-crushing module 7. The pre-grinding disc 701 is formed in a body shape, and the pre-grinding disc 701 is arranged in a terrace shape. The bottom of the rolling disc 3 is provided with a pre-grinding chamber 301 located outside the pre-grinding disc 701, and the pre-grinding chamber 301 is arranged in a straight cylinder shape, wherein the complete rice grains enter the pre-grinding chamber 301 from top to bottom, and the distance between the inner wall of the pre-grinding chamber 301 and the pre-grinding disc 701 gradually decreases, and the complete rice grains will be gradually squeezed and crushed into small particles by the pre-grinding disc 701, and then the small particles of rice particles will flow into between the rolling disc 3 and the fixed disc 2, and the upper surface of the rolling disc 3 is provided with a plurality of feed ports 302 connected to the top of the pre-grinding chamber 301, and the lower surface of the rolling disc 3 is provided with a plurality of transfer ports 303 connected to the bottom of the pre-grinding chamber 301.

[0055] In the present invention, when it is necessary to grind the whole rice grains into powder, the staff first puts the whole rice grains onto the top of the grinding disc 3, and then the whole rice grains flow into the interior of the pre-grinding chamber 301 through the feed port 302, and then the servo motor 12 is operated, and the servo motor 12 drives the grinding disc 3 to rotate. While the grinding disc 3 rotates, the inner wall of the pre-grinding chamber 301 rotates relative to the pre-grinding disc 701, and then the rice grains between the inner wall of the pre-grinding chamber 301 and the pre-grinding disc 701 are ground, and the ground rice grains will gradually descend along the interior of the pre-grinding chamber 301, and in this process, the rice grains will continue to be ground into smaller particles until they slide to the bottom of the pre-grinding chamber 301, and then the small rice particles in the pre-grinding chamber 301 will flow out to the grinding disc 3 along the transfer port 303. The rice grains in small granules will be crushed into powder between the rolling disk 3 and the fixed disk 2 at this time, and the powdered rice will subsequently flow out from the sides of the rolling disk 3 and the fixed disk 2 to the screening module 5, and the screening module 5 will introduce the rice grains that are not completely crushed into the circulating feeding module 4, and the circulating feeding module 4 will transport the rice grains that are not completely crushed to the top of the rolling disk 3 again, and the powdered rice will be discharged to the outside through the screening module 5. Compared with the traditional direct grinding method, this method can improve the grinding degree of rice and reduce the occurrence of incompletely crushed rice grains. In this process, the air supply module 6 will act synchronously and blow air to the powdered rice, so that the powdered rice can be discharged more fully and quickly, thereby avoiding the excessive accumulation of powdered rice.

[0056] Furthermore, the lower surface of the rolling disc 3 is configured as an upward concave surface, and the upper surface of the fixed disc 2 is configured as a convex surface corresponding to the concave surface, so that the small grains of rice between the rolling disc 3 and the fixed disc 2 can slide to both sides when being rolled again;

[0057] Furthermore, the outer surfaces of the fixed plate 2, the rolling plate 3, the pre-rolling plate 701 and the inner wall of the pre-rolling chamber 301 are all set to rough surfaces, so that the rice particles can be more fully rolled, increasing the degree of grinding of the rice particles, and correspondingly, the efficiency of its powder formation can be increased.

[0058] In a preferred embodiment, please refer to Figure 1 , Figure 2 and Figure 3A baffle plate 8 is fixedly installed on the top of the support seat 1, and the baffle plate 8 is located on the outside of the rolling disc 3 and the fixed disc 2 to prevent the ground rice from flying around. A support plate 801 is fixedly installed on the top of the baffle plate 8, and a servo motor 12 is fixedly installed on the top of the support plate 801. The servo motor 12 is electrically connected to an external power supply, and the output end of the servo motor 12 passes through the support plate 801 and is fixedly connected to the axis of the rolling disc 3. A material shifting rod 802 fixedly connected to the bottom end of the support plate 801 is also provided on the upper surface of the rolling disc 3. After the rice particles are put onto the top of the rolling disc 3, as the rolling disc 3 rotates, the rice particles above it also move at any time. If the rice particles are piled up too high, they will be blocked by the material shifting rod 802, thereby effectively preventing the un-powdered rice particles from piling up too high.

[0059] In addition, a material blocking ring is integrally formed at the outer edge of the upper surface of the rolling disc 3, so that the rice particles above the rolling disc 3 will not slide outward when the rolling disc 3 rotates.

[0060] Secondly, please also refer to Figure 1 and Figure 3 The circulating feeding module 4 includes a feeding frame 401 and a support frame 402. The feeding frame 401 is arranged in a spiral shape. The top of the feeding frame 401 is located at the edge above the rolling disc 3. A conveyor belt is arranged inside the feeding frame 401. The outer surface of the conveyor belt is also arranged to be a rough surface, so that when conveying un-powdered rice particles, the friction between the two can be increased. A material receiving notch is provided at the bottom of the feeding frame 401. The outer edge of the bottom of the baffle plate 8 is integrally formed with a plurality of upper discharge nozzles 803 located above the material receiving notch. The upper discharge nozzles 803 are used to discharge un-powdered rice particles. The support frame 402 is fixedly installed on the outer side of the feeding frame 401, and one end of the support frame 402 is fixedly connected to the outer edge of the baffle plate 8.

[0061] According to the above structure, the rice particles are discharged to the top of the screening module 5 after being crushed by the crushing disk 3 and the fixed disk 2. The screening module 5 screens out the un-powdered rice particles and feeds them into the upper discharge nozzle 803. Then the un-powdered rice particles flow into the receiving gap through the upper discharge nozzle 803. Finally, the un-powdered rice particles fall onto the top of the conveyor belt. The conveyor belt transports the un-powdered rice particles to the top of the crushing disk 3. Then, they reach between the crushing disk 3 and the fixed disk 2 through the feed port 302 and the pre-crushing chamber 301, so that the un-powdered rice particles receive secondary crushing. This reciprocating process makes it possible for the un-powdered rice particles to be stored and fed for the second time without having to be stored separately and fed for the second time. After the screening is completed, the second crushing can be performed immediately. Correspondingly, the powdering rate of the same batch of rice is increased.

[0062] For further understanding and explanation, see Figure 1 , Figure 3 and Figure 8A material guiding chamber 101 is provided on the outer edge of the support seat 1, and the material guiding chamber 101 is located on the outside of the screening module 5. A plurality of lower discharge nozzles 102 are integrally formed on the outer edge of the material guiding chamber 101, and the lower discharge nozzles 102 are used to discharge the powdered rice particles. The plurality of lower discharge nozzles 102 and the plurality of upper discharge nozzles 803 are arranged alternately with each other, and the plurality of lower discharge nozzles 102 are all located below the feeding frame 401, and the ports of the plurality of lower discharge nozzles 102 are provided with storage barrels or nylon bags for receiving materials.

[0063] It should be noted that an annular baffle is fixed to the outer side of the feeding frame 401, and the annular baffle is used to prevent the un-powdered rice and powdered rice discharged from the upper discharge nozzle 803 and the lower discharge nozzle 102 from splashing around.

[0064] In a preferred embodiment, please refer to Figure 3 and Figure 5 The screening module 5 includes a screening plate 501, a partition plate 502 and a guide block 503. A plurality of screening plates 501 are provided, and all are arranged inside the support seat 1, and all are used to screen the rice particles flowing out from between the rolling plate 3 and the fixed plate 2, and the rice particles can be screened by partition to prevent the discharged rice particles from piling up together. The partition plate 502 is integrally formed inside the support seat 1, and is used to separate the plurality of screening plates 501. The guide block 503 is integrally formed between adjacent screening plates 501;

[0065] A guide groove 5021 is formed in the middle of the partition plate 502 and is slidably sleeved on the outer surface of the guide block 503 .

[0066] Second, see Figure 1 , Figure 2 , Figure 7 and Figure 8 A carrying plate 9 is arranged below the support seat 1, and a vibration motor 10 is fixedly installed at the bottom end of the carrying plate 9. The vibration motor 10 is also electrically connected to an external power supply. A buffer module 11 is arranged between the carrying plate 9 and the support seat 1. The buffer module 11 is used to buffer the force between the carrying plate 9 and the support seat 1. A plurality of connecting plates 901 are fixedly connected to the bottom end of the carrying plate 9, and the top ends of the plurality of connecting plates 901 are respectively fixedly connected to the bottom ends of the plurality of screening plates 501.

[0067] According to the above structure, when the rice particles need to be screened, the staff first runs the vibration motor 10, the vibration motor 10 drives the bearing plate 9 to vibrate, the bearing plate 9 drives the screening plate 501 to vibrate through the connecting plate 901, and then the screening plate 501 drives the guide block 503 to slide along the inside of the guide groove 5021, so as to limit the screening plate 501 from being skewed during vibration, and while the bearing plate 9 is vibrating, the impact force on the support seat 1 is slowed down by the buffer module 11, and when the screening plate 501 is vibrating, the powder The shaped rice particles will pass through the screening plate 501 and fall into the interior of the material guiding chamber 101. Subsequently, the powdered rice particles in the material guiding chamber 101 will be blown under the action of the air supply module 6, so that the powdered rice particles can quickly flow out from the port of the lower discharge nozzle 102, while the un-powdered rice particles will flow into the interior of the feeding frame 401 through the upper discharge nozzle 803 under the shaking action of the screening plate 501, thereby achieving the purpose of separating the powdered rice particles and the un-powdered rice particles and transporting them to different areas respectively.

[0068] Secondly, please also refer to Figure 2 , Figure 7 , Figure 8 and Fig. 9 The buffer module 11 includes a fixed sleeve 1101, a buffer spring 1102 and a support rod 1103. The fixed sleeve 1101 is fixedly installed on the lower surface of the support seat 1, and the buffer spring 1102 is fixedly installed inside the fixed sleeve 1101. The support rod 1103 is arranged at the bottom end of the buffer spring 1102, and the bottom end of the support rod 1103 is also fixedly connected to the upper surface of the supporting plate 9. The support rod 1103 is restricted by the fixed sleeve 1101 and can only move in the vertical direction. Therefore, the supporting plate 9 can only vibrate in the vertical direction under the action of the vibration motor 10.

[0069] Furthermore, when the vibration motor 10 is in operation, the supporting plate 9 will inevitably vibrate at a high frequency, and the supporting plate 9 will drive the support rod 1103 to rise and fall along the inside of the fixed sleeve 1101 during vibration, and the buffer spring 1102 will be intermittently subjected to the squeezing force from the support rod 1103, thereby preventing the support rod 1103 from impacting the inner wall of the fixed sleeve 1101. Correspondingly, a part of the force exerted on the support seat 1 will be offset by the spring, and the support seat 1 can be placed more stably in the working area, and the grinding work of the rice grains by the grinding disk 3 and the fixed disk 2 above it will not be affected, so that the rice grains can be ground to a higher degree.

[0070] For further understanding and explanation, please also refer to Figure 7 , Figure 8 and Fig. 9The air supply module 6 includes a piston block 601, an air supply pipe 602 and an air outlet pipe 603. The piston block 601 is slidably arranged inside the fixed sleeve 1101. The air supply pipe 602 is fixedly connected to the top of the fixed sleeve 1101. The air outlet pipe 603 is connected to the inside of the air supply pipe 602. One end of the air outlet pipe 603 extends to the inside of the material guide chamber 101 and is located below the screening plate 501. The port of the air outlet pipe 603 is flush with the port of the lower discharge nozzle 102, so that the powdered rice particles inside the material guide chamber 101 can be discharged quickly and smoothly.

[0071] Among them, the piston block 601 and the fixed sleeve 1101 are set to be interference fit, and the piston block 601 can be set to be an elastic rubber material. When it slides along the inside of the fixed sleeve 1101, it can ensure that the gas inside the fixed sleeve 1101 can be squeezed into the inside of the air supply pipe 602.

[0072] It should be noted that there are multiple fixed sleeves 1101 , all of which are located at the outer edge of the supporting plate 9 . The air supply pipe 602 connects the multiple fixed sleeves 1101 to each other, and the air outlet pipe 603 leads to the interior of the material guiding chamber 101 .

[0073] A plurality of ventilation ports are provided at the bottom of the fixed sleeve 1101 , and in the initial state, the ventilation ports are located above the piston block 601 . After the piston block 601 moves to the bottom of the ventilation ports, the gas inside the fixed sleeve 1101 can be replenished.

[0074] Specifically, when the support rod 1103 moves, the piston block 601 slides along the inner wall of the fixed sleeve 1101, so that the gas inside the fixed sleeve 1101 can be squeezed into the air supply pipe 602. Since the movement frequency of the support rod 1103 is high, the piston block 601 will continuously squeeze the air into the air supply pipe 602. In this process, each time the piston block 601 moves below the air exchange port, the air inside the fixed sleeve 1101 will be replenished, thereby ensuring that the piston block 601 can be pushed into the air supply pipe 602 each time. Part of the gas is squeezed out from the air supply pipe 602 and blown out to the inside of the material guide chamber 101 through the air outlet pipe 603 after the internal air pressure of the air supply pipe 602 increases, thereby forming an airflow inside the material guide chamber 101. The airflow will carry the powdered rice particles inside the material guide chamber 101 and be discharged through the lower discharge nozzle 102, thereby avoiding the excessive accumulation of powdered rice particles inside the material guide chamber 101, and the powdered rice particles inside the material guide chamber 101 will not seep back to the top of the screening plate 501 when the screening plate 501 vibrates.

[0075] A rice processing method uses the above-mentioned automatic rice mill during the rice processing.

[0076] The working principle of the present invention is as follows: when it is necessary to grind the whole rice grains into powder, the staff first puts the whole rice grains onto the top of the grinding disc 3, and then the whole rice grains flow into the interior of the pre-grinding chamber 301 through the feed port 302, and then the servo motor 12 is operated, and the servo motor 12 drives the grinding disc 3 to rotate. While the grinding disc 3 rotates, the inner wall of the pre-grinding chamber 301 rotates relative to the pre-grinding disc 701, and then the rice grains between the inner wall of the pre-grinding chamber 301 and the pre-grinding disc 701 are ground, and the ground rice grains will gradually descend along the interior of the pre-grinding chamber 301, and in this process, the rice grains will continue to be ground into smaller particles until they slide to the bottom of the pre-grinding chamber 301, and then the small rice particles inside the pre-grinding chamber 301 will flow out along the transfer port 303 to the grinding Between the pressing plate 3 and the fixed plate 2, at this time, small granular rice particles will be crushed into powder between the rolling plate 3 and the fixed plate 2, and the powdered rice will subsequently flow out from the sides of the rolling plate 3 and the fixed plate 2 to the screening module 5, and the screening module 5 will introduce the incompletely crushed rice particles into the circulating feeding module 4, and the circulating feeding module 4 will transport the incompletely crushed rice particles to the top of the rolling plate 3 again, and the powdered rice will be discharged to the outside through the screening module 5. Compared with the traditional direct grinding method, this method can improve the grinding degree of rice and reduce the occurrence of incompletely crushed rice particles. During this process, the air supply module 6 will act synchronously and blow air to the powdered rice, so that the powdered rice can be discharged more fully and quickly, thereby avoiding the excessive accumulation of powdered rice.

[0077] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
