Description

Technical Field

[0001] This invention relates to the field of energy-saving grinding equipment technology, specifically a grinding equipment for rice flour processing. Background Technology

[0002] The production of rice noodles mainly includes steps such as selecting and soaking rice, grinding, dehydration, steaming and shaping, and cooling and packaging. Grinding requires the use of relevant grinding equipment, such as rice grinders. However, existing rice grinders generally mix rice by manually adding water to the feeding device. When adding water manually, there is a large difference in the control ratio between the amount of water added and the amount of rice fed, which affects the grinding efficiency of rice.

[0003] To address the above issues, CNB published a feeding device for a rice mill, including a hopper cylinder with a conical bottom. When rice is added to the rice mill via the feeding device, the rice falls inside the hopper cylinder, pressing down on the rice weighing plate. This causes four springs on the outer side of the rice weighing plate to contract, which in turn moves the top of a connecting rod downwards. This allows the side of the connecting rod to move a water flow regulating plate inside the guide housing via a transmission rod.

[0004] However, in actual use, we found that the core of the grinder is to use an extremely narrow grinding gap to grind the mixture of rice and water. The references control the water intake by the weight of the rice, but in actual operation, the fineness of the rice is controlled by adjusting the grinding gap. That is, if there is more rice and less water in the grinding gap, the rice paste will be thick; if there is less rice and more water, the rice paste will be thin. Therefore, only controlling the overall water-to-rice ratio without considering the fineness of grinding will result in uneven grinding, which will directly affect the taste of the rice noodles produced.

[0005] Therefore, we propose a grinding device for rice noodle processing. Summary of the Invention

[0006] One of the technical problems to be solved in this application is: how to design a grinding equipment for rice noodle processing that can adjust the water intake according to the grinding gap.

[0007] To solve the above-mentioned technical problems, this application provides a grinding device for rice noodle processing, including a vertical grinding box and a detachable box cover. The box cover is provided with a rice feeding hopper and a water tank. A grinding element is provided between the vertical grinding box and the box cover. The box cover is provided with a gap adjustment control and a water injection mechanism.

[0008] In some embodiments, the vertical grinding box includes an equipment area and a grinding area. The grinding area is provided with a rice slurry outlet. The grinding component includes an energy-saving motor provided in the equipment area. The output end of the energy-saving motor is provided with a drive shaft. The drive shaft is rotatably located in the middle of the vertical grinding box and extends to the grinding area. A rotating grinding disc is provided on the drive shaft located at one end of the grinding area. A lifting grinding disc is movably provided in the grinding area.

[0009] In some embodiments, the top of the rotating grinding disc is inclined, the bottom of the lifting grinding disc is inclined, and the bottom of the lifting grinding disc is evenly provided with multiple bent grooves.

[0010] In some embodiments, the gap adjustment control includes a hollow screw threaded to the middle of the box cover, a drive turntable is provided at the top of the hollow screw, the rice hopper is inserted into the drive turntable, and the lifting grinding disc is provided at the bottom of the hollow screw.

[0011] In some embodiments, the water injection mechanism includes an installation cavity disposed on a tank cover, a rotating cavity rotatably disposed within the installation cavity via a sealed bearing, the rotating cavity being located between a hollow screw and a drive turntable, the water tank and the installation cavity being connected by a hose, a compression linkage assembly disposed on the tank cover, a water filling adjustment control disposed within the water tank, multiple vertical grooves communicating with the rotating cavity being formed on the side wall of the hollow screw, an annular groove being formed on the lifting grinding disc, and multiple sets of drainage holes being formed on the lifting grinding disc, the vertical grooves, the annular grooves and the drainage holes being sequentially connected.

[0012] In some embodiments, the compression linkage assembly includes a first support frame and a second support frame disposed on the housing, a connecting member is disposed between the first support frame and the second support frame, an elastic member is disposed on the connecting member, and a transmission member is disposed on the second support frame.

[0013] In some embodiments, the connecting member includes a fixed cavity 1 disposed on a support frame 1, a piston rod 1 disposed in the fixed cavity 1, a fixed cavity 2 disposed on the support frame 2, a piston rod 2 disposed in the fixed cavity 2, the fixed cavity 1 and the fixed cavity 2 are connected by a flexible hose, and a driving medium is disposed in the rodless cavity of the fixed cavity 1 and the fixed cavity 2.

[0014] In some embodiments, the elastic element includes a ball disposed at the top of a piston rod, the ball being in contact with a rotating cavity, and a return spring sleeved on the outer side of the piston rod, the two ends of the return spring being connected to the ball and the fixed cavity, respectively.

[0015] In some embodiments, the transmission component includes a shift rack slidably disposed inside the support frame two, the shift rack being connected to the piston rod two, a connecting shaft being provided on the water tank, and a transmission gear being provided on the connecting shaft that meshes with the shift rack.

[0016] In some embodiments, the water filling control device includes a fixed groove plate disposed at the drain outlet of the water tank, a movable groove plate rotatably disposed on the fixed groove plate, an external gear ring disposed on the movable groove plate, and a fixed gear meshing with the external gear ring disposed on the connecting shaft.

[0017] This invention has at least the following beneficial effects: 1. This allows operators to rotate the drive turntable, causing the hollow screw to move up and down in the housing cover, thereby raising and lowering the lifting grinding disc and changing the gap between the lifting grinding disc and the rotating grinding disc. The energy-saving motor design makes the entire device more energy-efficient and environmentally friendly, and also saves the company certain production costs. 2. The water addition speed is automatically adjusted according to the grinding action. When the grinding fineness is high (small gap), the water addition speed is increased to ensure sufficient water is mixed with the fine rice flour; when the grinding fineness is low (large gap), the water addition speed is slowed down to avoid the rice paste being too thin. This achieves real-time linkage between water addition and grinding, improving control precision. 3. By precisely controlling the grinding fineness and automatically adjusting the water addition speed, the rice milk has a more uniform consistency and a better taste, making it suitable for subsequent processing. Automated control reduces the time and error of manual adjustment, enabling continuous and stable production, and is suitable for large-scale processing. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-10 The present invention provides a technical solution: A grinding device for rice flour processing includes a vertical grinding box 1 and a detachable box cover 2. The box cover 2 is provided with a rice feeding hopper 3 and a water tank 4. A grinding element 5 is provided between the vertical grinding box 1 and the box cover 2. The box cover 2 is provided with a gap adjustment control 6 and a water injection mechanism 7. Both the vertical grinding chamber 1 and the lid 2 are common existing structures. In this solution, the vertical grinding chamber 1 and the lid 2 adopt a split structure commonly found in food processing equipment. The two are detachably connected. Specifically, a separate design is preferred. The lid 2 is easily fixed and loosened by a locking buckle installed on the vertical grinding chamber 1. This greatly facilitates the internal cleaning, maintenance, and post-use hygiene of the equipment. Of course, this connection method is not limited to this. For example, a hinged flip-type design or other conventional methods can also be used. The core is to achieve flexible opening and closing of the grinding chamber to adapt to different operating needs.

[0022] The vertical grinding box 1 includes an equipment area and a grinding area. The grinding area is provided with a rice slurry outlet. The grinding component 5 includes an energy-saving motor 51 located in the equipment area. The output end of the energy-saving motor 51 is provided with a drive shaft 52. The drive shaft 52 is rotatably located in the middle of the vertical grinding box 1 and extends to the grinding area. A rotating grinding disc 53 is provided on the drive shaft 52 located at one end of the grinding area. A lifting grinding disc 54 is movably provided in the grinding area. The grinding area and the equipment area are connected by a sealed bearing. An energy-saving electric motor 51 drives the drive shaft 52 to rotate, which in turn drives the rotating grinding disc 53 to rotate. The grinding gap is between the rotating grinding disc 53 and the lifting grinding disc 54. The fineness of the rice slurry can be adjusted by adjusting this grinding gap. The rice slurry outlet design in this scheme takes into account both efficient discharge and structural simplicity. It consists of two parts: one is an inclined groove directly opened on the side wall of the grinding zone, which serves as the initial collection and outflow channel for the rice slurry; the other is an inclined discharge guide plate correspondingly set on the outer wall of the grinding zone. Together, these two constitute a continuous outlet with clear guidance. During the grinding process, the rice slurry that is thrown out will collect along the inclined groove and slide smoothly over the discharge guide plate, and finally be discharged naturally by gravity. The discharge outlet needs to be connected to an external receiving container. This structure ensures that the rice slurry can be collected in a concentrated and orderly manner. At the same time, the entire discharge channel is smooth, which greatly facilitates the subsequent cleaning work and meets the strict hygiene requirements of food processing equipment.

[0023] When in use, the energy-saving motor 51 starts and drives the drive shaft 52 to rotate. The drive shaft 52 drives the rotating grinding disc 53 to rotate. The rice grains falling from the rice hopper 3 will fall between the lifting grinding disc 54 and the rotating grinding disc 53. Then, when the rotating grinding disc 53 rotates, the rice grains and the water injection mechanism 7 are ground into rice paste. The ground rice paste is discharged from the rice paste outlet.

[0024] Example 2: Please refer to Figures 3-6 The present invention provides a technical solution: A grinding device for rice flour processing, wherein the top of the rotating grinding disc 53 is inclined, the bottom of the lifting grinding disc 54 is inclined, and a plurality of bending grooves 13 are evenly provided at the bottom of the lifting grinding disc 54. An annular storage cavity is provided at the center of the lifting grinding disc 54, and the annular storage cavity is connected to the bending grooves 13. The rotating grinding disc 53 gradually decreases in height from the center to the surrounding area, and the lifting grinding disc 54 also gradually decreases in height from the center to the surrounding area, so that rice grains, water or rice paste can enter the grinding area under their own gravity. The annular storage cavity and the bent groove 13 form a temporary storage space for rice grains.

[0025] Example 3: Please refer to Figures 3-6 The present invention provides a technical solution: A grinding device for rice noodle processing, wherein the gap adjustment control 6 includes a hollow screw 61 threadedly connected to the middle of the box cover 2, a drive turntable 62 is provided on the top of the hollow screw 61, the rice feeding hopper 3 is inserted into the drive turntable 62, and the lifting grinding disc 54 is provided at the bottom of the hollow screw 61. The hollow part in the middle of the hollow screw 61 is the area where rice grains fall into the rice hopper 3. It is also another temporary storage space for rice grains after the annular storage chamber and the bent groove 13 are filled with rice grains. In this solution, the shape of water tank 4 has been specially optimized, and it has been designed as a unique arc structure. This arc is not a complete circle, but cleverly forms an open area on the side wall of water tank 4. This design provides ample space for hand operation, so that when the operator needs to adjust the grinding gap, his / her hand can pass through this area without any obstruction and directly and smoothly touch and rotate the drive turntable 62 located on the inner side. This optimization greatly improves the convenience and humanization of equipment operation without affecting the water storage function of water tank 4, and solves the operation interference problem that may exist in the original layout. Meanwhile, in order to improve the utilization rate of water inside water tank 4, the drain outlet of water tank 4 is designed to be at the lowest position, and all other positions are higher than this position, so that water can be completely drained.

[0026] Example 4: Please refer to Figures 1-10 The present invention provides a technical solution: A grinding device for rice flour processing, wherein the water injection mechanism 7 includes an installation cavity 71 disposed on a tank cover 2, a rotating cavity 72 rotatably disposed within the installation cavity 71 via a sealed bearing, the rotating cavity 72 being located between a hollow screw 61 and a drive turntable 62, a water tank 4 being connected to the installation cavity 71 via a hose, a compression linkage assembly 8 disposed on the tank cover 2, a water addition adjustment control 12 disposed within the water tank 4, a plurality of vertical grooves 73 communicating with the rotating cavity 72 being opened on the side wall of the hollow screw 61, an annular groove 74 being opened on the lifting grinding disc 54, and a plurality of drainage holes 75 being opened on the lifting grinding disc 54, the vertical grooves 73, the annular grooves 74 and the drainage holes 75 being sequentially connected, each set of drainage holes 75 being connected to an adjacent bending groove 13, for cooling the rice paste in the bending groove 13 and making it flow; The mounting cavity 71 is fixedly installed on the top of the cover 2, while the rotating cavity 72 is rotatable relative to the cover 2 and the mounting cavity 71. Due to the installation of the sealed bearing, there is no water leakage when the rotating cavity 72 rotates. Multiple drainage holes 75 are also provided in the middle of the rotating cavity 72 to drive the rice grains in the hollow screw 61 to flow.

[0027] The extrusion linkage assembly 8 includes a first support frame 81 and a second support frame 82 disposed on the housing. A connecting member 9 is disposed between the first support frame 81 and the second support frame 82. An elastic member 10 is disposed on the connecting member 9. A transmission member 11 is disposed on the second support frame 82. The connecting member 9 includes a fixed cavity 91 disposed on a support frame 81, a piston rod 92 disposed in the fixed cavity 91, a fixed cavity 93 disposed on the support frame 82, a piston rod 94 disposed in the fixed cavity 93, the fixed cavity 91 and the fixed cavity 93 are connected by a flexible hose, and a driving medium is disposed in the rodless cavity of the fixed cavity 91 and the fixed cavity 93. The driving medium can be high-performance hydraulic oil, or silicone oil, glycerin aqueous solution, etc., as long as it can transmit pressure stably and reliably in various working environments.

[0028] The elastic element 10 includes a ball 101 disposed on the top of the piston rod 92. The ball 101 is in contact with the rotating cavity 72. A return spring 102 is sleeved on the outside of the piston rod 92. The two ends of the return spring 102 are respectively connected to the ball 101 and the fixed cavity 91. When the drive turntable 62 rotates, the rotating cavity 72 also rotates and descends, thus squeezing the ball 101 and the return spring 102. In this way, the piston rod 92 moves within the fixed cavity 91, and the piston rod 94 moves within the fixed cavity 93 via the hose.

[0029] The transmission component 11 includes a shift rack 111 slidably disposed inside the support frame 2 82. The shift rack 111 is connected to the piston rod 2 94. The water tank 4 is provided with a connecting shaft 112, and the connecting shaft 112 is provided with a transmission gear 113 that meshes with the shift rack 111. The piston rod 94 shifts, causing the shift rack 111 to slide within the support frame 82. The shift of the shift rack 111 causes the transmission gear 113 and the connecting shaft 112 to rotate.

[0030] The water addition control 12 includes a fixed groove plate 121 set at the drain outlet of the water tank 4, a movable groove plate 122 rotatably set on the fixed groove plate 121, an external gear ring 123 set on the movable groove plate 122, and a fixed gear 124 meshing with the external gear ring 123 set on the connecting shaft 112. In this design, both the fixed slot plate 121 and the movable slot plate 122 are provided with circular slots, but this is not limited to them; they can also be fan-shaped slots or arc-shaped slots, etc.

[0031] The connecting shaft 112 drives the fixed gear 124 to rotate, and the fixed gear 124 drives the external gear ring 123 that meshes with it to rotate. The movable groove plate 122 rotates accordingly. Since both the fixed groove plate 121 and the movable groove plate 122 have slots, the amount of water added can be adjusted by adjusting the overlap of the slots. In other words, the amount of water added is controlled at the same time as the grinding gap is adjusted.

[0032] When in use, the energy-saving motor 51 starts and drives the drive shaft 52 to rotate. The drive shaft 52 drives the rotating grinding disc 53 to rotate. The rice grains falling from the rice hopper 3 will fall between the lifting grinding disc 54 and the rotating grinding disc 53. Then, when the rotating grinding disc 53 rotates, the rice grains and the water injection mechanism 7 are ground into rice paste. The ground rice paste is discharged from the rice paste outlet. When it is necessary to adjust the grinding gap, the operator holds the drive turntable 62 to rotate it. The drive turntable 62 drives the hollow screw 61 to rotate, thereby realizing the rotation and lifting of the grinding disc 54 and the adjustment of the grinding gap. During the process, the rotating cavity 72 also rotates and rises and falls, thus squeezing the ball bearing 101 and the return spring 102. This causes the piston rod 92 to move within the fixed cavity 91, which in turn drives the piston rod 94 to move within the fixed cavity 93 via the hose. The movement of the piston rod 94 causes the shifting rack 111 to slide within the support frame 82. The shift of the shifting rack 111 causes the transmission gear 113 and the connecting shaft 112 to rotate. The connecting shaft 112 drives the fixed gear 124 to rotate, and the fixed gear 124 drives the outer gear ring 123, which meshes with it, to rotate. The movable slot plate 122 rotates accordingly. Since both the fixed slot plate 121 and the movable slot plate 122 have slots, the amount of water added can be adjusted by adjusting the overlap of the slots. This means that the amount of water added is controlled while adjusting the grinding gap.
