Description

Technical Field

[0001] The invention relates to the technical field of grinding devices, in particular to a fine grinding device and a pulverizing method for rice noodle production. Background Art

[0002] Rice noodles refer to rice products in the form of strips or threads, which are made from rice through processes such as washing, soaking, grinding, steaming, sheeting (extrusion), re-steaming, cooling, and dryer packaging. In the production process of rice noodles, grinding, that is, fine grinding of rice, is very important. It can grind rice into rice slurry particles with extremely small particle size, making the texture of the finished rice noodles more uniform and delicate, which plays an important role in the smooth shaping and smooth taste of the rice noodles in subsequent processing.

[0003] Chinese patent CN109647579B discloses a rice grinding device for making rice noodles, which can adjust the distance between the disc-shaped grinding roller and the grinding disc, thereby adjusting the grinding coarseness. However, when grinding the rice, it may not be ground thoroughly, and the rice residue will accumulate on the edge of the filter screen. However, in order to ensure that the rice noodles can be stored for a long time, the rice used in large-scale industrial production of rice noodles is refined rice with only the endosperm part left. The rice residue produced after the rice is ground is just broken rice that has not been ground to a suitable particle size, and does not contain other ingredients that are inedible and affect the taste. The above device cannot directly recycle the rice residue for re-grinding. Discarding the rice residue will cause a waste of raw materials. Collecting the rice residue again when replacing the filter screen is also prone to cause the rice residue to deteriorate due to a long time.

[0004] Chinese patent CN113117819B discloses a peanut oil processing and grinding device. By setting a conveying cylinder and a spiral plate, the grinding residue in the grinding product can be re-grinded. However, the device separates the peanut residue and peanut oil through a filter plate, and the peanut residue may clog the filter plate, resulting in a gradual decrease in the filtering effect. In addition, a large amount of peanut oil is also mixed in the peanut residue. Directly conveying the peanut residue through the spiral plate will result in a decrease in the oil output rate. This situation also exists in the grinding of rice flour production. Summary of the invention

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 8 and Fig. 9The present invention provides a fine grinding device, including a chassis 1, a grinding bin 2, a bin cover 3, a lower hopper 4 and a water tank 9. The grinding bin 2 is installed above the chassis 1, one end of the bin cover 3 is hingedly installed with one end of the grinding bin 2, the discharge end of the lower hopper 4 is communicated with the interior of the grinding bin 2, the water tank 9 is arranged above the lower hopper 4, and a faucet is installed on one side wall of the water tank 9, a rotating grinding wheel 21 is installed inside the grinding bin 2, a fixed grinding wheel 31 is fixedly installed on the inner wall of the bin cover 3, the fixed grinding wheel 31 and the rotating grinding wheel 21 are arranged oppositely, and a screen is arranged below the grinding bin 2. The screening mechanism 7 includes a screening bin 71 and a gauze conveyor belt 72. The top of the screening bin 71 is connected to the lower end of the grinding bin 2. The two sides of the bottom of the screening bin 71 are respectively provided with a slurry discharge port 711 and a grinding residue discharge port 712. The gauze conveyor belt 72 is used to receive the ground material discharged from the grinding bin 2, so that the slurry flows through the gauze to the slurry discharge port 711, and the grinding residue is transported to the grinding residue discharge port 712. A spiral lifting pipe 8 is provided on one side of the chassis 1. The spiral lifting pipe 8 is used to transport the grinding residue output from the grinding residue discharge port 712 to the lower hopper 4; A rotating shaft 721 is arranged inside the gauze conveyor belt 72, and the rotating shaft 721 is used to drive the gauze conveyor belt 72 to rotate, and a reciprocating mechanism 73 is installed between the rotating shaft 721 and the screening bin 71, and the reciprocating mechanism 73 is used to drive the rotating shaft 721 to vibrate linearly; The gauze conveyor belt 72 is also provided with a slag pressing component 75 and a long-haired roller brush 77. The slag pressing component 75 is used to squeeze out the slurry in the ground slag, and the long-haired roller brush 77 is used to sweep the ground slag on the lower surface of the gauze conveyor belt 72 so that the ground slag can leave the gauze conveyor belt 72 and fall into the ground slag discharge port 712.

[0023] As can be seen from the above, by setting the fixed grinding wheel 31 and the rotating grinding wheel 21, the wet rice output from the lower hopper 4 is ground and crushed by the fixed grinding wheel 31 and the rotating grinding wheel 21. Since the diameters of the fixed grinding wheel 31 and the rotating grinding wheel 21 are much smaller than the inner diameter of the grinding bin 2, an annular channel with a large cross-sectional area is formed between the inner wall of the grinding bin 2 and the fixed grinding wheel 31 and the rotating grinding wheel 21. The rice residue and rice slurry produced by grinding can fall into the interior of the screening bin 71, and the rice residue will not accumulate in the interior of the grinding bin 2 and cause it to get stuck. By setting the gauze conveyor belt 72, the rice residue and rice slurry that fall into the screening bin 71 are separated on the gauze conveyor belt 72, and the rice slurry flows through the gauze to the slurry discharge port 711, while the rice residue is transported to the grinding residue discharge port 712. By setting the slag pressing component 75, the gauze conveyor belt 72 can be pressed. The rice residue transported from the upper part is squeezed, thereby squeezing out the rice slurry in the rice residue, thereby preventing more rice slurry from being re-transported to the lower hopper 4 through the spiral lifting pipe 8. By arranging the reciprocating mechanism 73, the gauze conveyor belt 72 is constantly vibrating during the working process. On the one hand, it can prevent the rice residue from accumulating in the middle of the gauze conveyor belt 72, so that the slag pressing component 75 can better squeeze the rice slurry and squeeze out more rice slurry from the rice residue. On the other hand, the vibration of the gauze conveyor belt 72 can increase the speed at which the rice slurry passes through the gauze and reduce the probability of the rice residue clogging the gauze, thereby maintaining the performance of the gauze conveyor belt 72 and extending the cleaning and replacement intervals. By arranging the long-haired roller brush 77, the rice residue sticking to the gauze conveyor belt 72 can be cleaned off, thereby preventing the rice residue from falling into the slurry discharge port 711 and affecting the quality of the rice slurry.

[0024] When the device is working, wet rice that has been soaked and drained is added to the lower hopper 4, water is added to the water tank 9 through an external water source, the tap is turned on and the water outlet speed is controlled so that the water flows through the lower hopper 4, the grinding chamber 2 and the screening chamber 71 and is discharged from the slurry outlet 711; The rotating grinding wheel 21 is controlled to rotate and the fixed grinding wheel 31 to grind the wet rice, and the ground material falls into the screening bin 71 and falls onto the gauze conveyor belt 72; The slurry in the ground material passes through the gauze of the gauze conveyor belt 72 and falls to the bottom of the screening bin 71, and flows at the bottom of the screening bin 71 and is discharged from the slurry discharge port 711; The rice residue in the ground material is transported by the gauze conveyor belt 72, and the slurry of the residue in the rice residue is squeezed out by the residue pressing component 75, so that the rice residue with reduced water content is transported to a position close to the grinding residue discharge port 712 and falls from the gauze conveyor belt 72, and the rice residue stuck on the gauze conveyor belt 72 is cleaned by the long-haired roller brush 77.

[0025] Embodiment 2: Figure 3 and Figure 4As shown, the difference between this embodiment and the above embodiment lies in that a horizontal feed pipe 22 is fixedly installed at one end of the grinding bin 2, the upper end of the horizontal feed pipe 22 is connected to the discharge end of the lower hopper 4, and one end of the horizontal feed pipe 22 passes through the outer wall of the grinding bin 2 and extends to the interior of the grinding bin 2, a circular hole 211 adapted for rotation with the horizontal feed pipe 22 is opened at one end of the rotating grinding wheel 21, and a conical hole 212 connected to the circular hole 211 is opened at the other end of the rotating grinding wheel 21, a disassembly plate 213 is fixedly installed on the inner wall of the conical hole 212, a grinding drive shaft 5 is fixedly installed at one end of the disassembly plate 213, a driving motor 6 is fixedly installed on the upper surface of the chassis 1, and the driving end of the driving motor 6 is connected to the grinding drive shaft 5 through a transmission belt pulley.

[0026] As can be seen from the above, the grinding drive shaft 5 is driven by the driving motor 6 to rotate the rotating grinding wheel 21. After the rice enters the horizontal feeding pipe 22 from the lower hopper 4, it falls between the fixed grinding wheel 31 and the rotating grinding wheel 21 through the circular hole 211 and the conical hole 212 to be ground.

[0027] The horizontal conveying pipe 22 is provided with a spiral blade 221 and a cutting blade 222 inside. The spiral blade 221 and the cutting blade 222 are both fixedly mounted on the grinding drive shaft 5. The cutting blade 222 is arranged at one end of the grinding drive shaft 5 close to the disassembly plate 213.

[0028] As can be seen from the above, by providing the spiral blade 221, it is possible to prevent the rice from accumulating in the horizontal feeding pipe 22 and being unable to enter between the fixed grinding wheel 31 and the rotating grinding wheel 21. By providing the cutting blade 222, the rice can be cut. Since the rice ground in this embodiment is wet rice that has been soaked and drained, the hardness of the wet rice is relatively small, which is convenient for cutting.

[0029] Embodiment 3: Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.12As shown, the difference between this embodiment and the above embodiment is that the reciprocating mechanism 73 includes a connecting plate 731, a sleeve rod 732, a driving gear 7321, a transmission rod 733, a passive gear 7331, a spiral tooth 7332, a rotating rod 734, a worm gear 7341, a rotating disk 7342 and a rotating plate 735, the two ends of the connecting plate 731 are respectively rotatably connected to the two rotating shafts 721, one end of the sleeve rod 732 is rotatably connected to the inner wall of one side of the screening bin 71, and the other end of the sleeve rod 732 is provided with a slide groove 7322, one end of the rotating shaft 721 is fixedly mounted with a slider 7211 slidably connected to the slide groove 7322, and both ends of the transmission rod 733 are rotatably connected to the inner wall of the screening bin 71. One side inner wall is rotatably connected, the driving gear 7321 is sleeved and fixed on the outer surface of one of the sleeve rods 732, the passive gear 7331 is meshed and connected with the driving gear 7321, and the passive gear 7331 is fixedly mounted on one end of the transmission rod 733, the helical teeth 7332 are fixedly mounted on the transmission rod 733, the rotating rod 734 is rotatably connected with the inner bottom wall of the screening bin 71, the worm gear 7341 and the turntable 7342 are both fixedly mounted on the rotating rod 734, the worm gear 7341 is meshed and connected with the helical teeth 7332, one end of the rotating plate 735 is rotatably connected with one side surface of the connecting plate 731, and the other end of the rotating plate 735 is rotatably connected with the turntable 7342 deviating from the center of the circle.

[0030] As can be seen from the above, since one end of the sleeve rod 732 is provided with a slide groove 7322, one end of the rotating shaft 721 is fixedly installed with a slider 7211 slidably connected to the slide groove 7322, when the sleeve rod 732 rotates, it can drive the rotating shaft 721 to rotate, and at the same time, the rotating shaft 721 can slide relative to the sleeve rod 732. Since the passive gear 7331 is meshed with the active gear 7321, when the sleeve rod 732 rotates, it can drive the transmission rod 733 to rotate. Since the worm gear 7341 is meshed with the helical gear 7332, when the transmission rod 733 rotates, it can The rotating rod 734 is driven to rotate, and since one end of the rotating plate 735 is rotationally connected to one side of the connecting plate 731, and the other end of the rotating plate 735 is rotationally connected to the turntable 7342 offset from the center of the circle, when the rotating rod 734 drives the turntable 7342 to rotate, the rotating plate 735 can push the connecting plate 731 to move back and forth in a straight line, so that the gauze conveyor belt 72 can vibrate in a straight line perpendicular to the conveying direction during the process of conveying rice residue, thereby flattening the rice residue falling on the gauze conveyor belt 72 and increasing the speed at which the rice slurry passes through the gauze.

[0031] A rotating block 722 is fixedly installed at both ends of the rotating shaft 721, a belt 723 is fixedly installed at both ends of the mesh conveyor belt 72, the rotating block 722 is transmission-connected with the belt 723, a control motor 74 is fixedly installed on the outer wall of one side of the screening bin 71, and the driving end of the control motor 74 is fixedly connected to one of the rotating shafts 721.

[0032] As can be seen from the above, by providing the rotating block 722 and the belt 723, the rotating shaft 721 can drive the gauze conveyor belt 72 to rotate and transport materials.

[0033] Embodiment 4: Figure 5 , Fig.10 and Fig.11 As shown, the difference between this embodiment and the above embodiment lies in that the slag pressing component 75 includes a mounting plate 751, a supporting wheel 752, a slide plate 753, an extrusion wheel 754 and an extrusion spring 755, the two ends of the lower surface of the mounting plate 751 are respectively fixedly connected to the two connecting plates 731, the two ends of the supporting wheel 752 are rotatably connected to the two side walls of the mounting plate 751, the two ends of the slide plate 753 are slidably connected to the two side walls of the mounting plate 751, the extrusion wheel 754 is rotatably mounted on the lower surface of the slide plate 753, the supporting wheel 752 and the extrusion wheel 754 are respectively arranged inside and above the mesh conveyor belt 72, and the two ends of the extrusion spring 755 are respectively fixedly connected to the lower surface of the mounting plate 751 and the upper surface of the slide plate 753.

[0034] As can be seen from the above, since the slag pressing component 75 is installed on the connecting plate 731, the supporting wheel 752 and the extruding wheel 754 move back and forth with the vibration of the connecting plate 731. Due to the setting of the extruding spring 755, there is a certain clamping force between the extruding wheel 754 and the supporting wheel 752, so that the rice slag between the extruding wheel 754 and the supporting wheel 752 is squeezed, and a part of the rice slurry in the rice slag can be squeezed out.

[0035] Scraping plates 76 are distributed at intervals inside the mesh conveyor belt 72 . The scraping plates 76 are arranged on both sides of the supporting wheel 752 , and both ends of the scraping plates 76 are fixedly connected to the connecting plates 731 .

[0036] As can be seen from the above, the scraper plate 76 is provided to increase the speed at which the rice slurry drips from the gauze conveyor belt 72, so as to prevent the rice slurry from being squeezed out of the rice residue and then being absorbed by the rice residue again.

[0037] The long-haired roller brush 77 is arranged below the mesh conveyor belt 72 and near the slag discharge port 712, and the two ends of the long-haired roller brush 77 are rotatably connected to the inner walls of the screening bin 71 on both sides, and the long-haired roller brush 77 is connected to the adjacent sleeve rod 732 through a transmission pulley.

[0038] As can be seen from the above, since the rice slurry has a certain viscosity, the rice residue can be swept off the gauze conveyor belt 72 by providing a long-haired roller brush 77.

[0039] The screening mechanism 7 also includes a conveyor belt clearing component 78, which includes a sliding hole 781, a sliding plate 782, an elastic fine thorn 783, a return spring 784, a wheel rod 785 and a cam 786. The sliding hole 781 is opened on the connecting plate 731, and both ends of the sliding plate 782 are slidingly connected to the sliding hole 781, and the sliding plate 782 is arranged inside the mesh conveyor belt 72. The elastic fine thorn 783 is fixedly installed on the lower surface of the sliding plate 782, and both ends of the return spring 784 are fixedly connected to the bottom wall of the sliding hole 781 and the lower surface of the sliding plate 782 respectively.
