Abstract
Description
Technical Field
[0001] This utility model relates to the field of soybean product processing, specifically to a soybean product grinding machine. Background Technology
[0002] Soy products are foods made primarily from soybeans, mung beans, green beans, peas, broad beans, and other legumes. Most soy products are tofu and its derivatives, made from coagulated soybean milk. Making soy milk from soybeans requires a soy milk machine. Existing soy milk machines generally use a motor to drive two grinding discs rotating in opposite directions, or one disc remaining stationary while the other rotates, to grind the soybean raw materials. Water is continuously added to keep the raw materials moist, producing soybean residue and soy milk. However, production experience has shown that the raw materials often have large particles after grinding, indicating that the soybeans are not thoroughly ground. They need to be mixed with water and stirred before being ground again in the soy milk machine. This increases the production process, consumes more production time, and increases costs.
[0003] Soybean dregs can be recycled after being crushed and ground, and can be used as feed or further processed into food. However, the ground soybean dregs are relatively fluffy and have a large volume. Soy milk makers simply extract the soybean dregs and cannot compress them, which results in the soybean dregs taking up a lot of space when refrigerated and being inconvenient to transport later.
[0004] In summary, existing soy milk makers require a second grinding of the soy pulp, adding extra steps and production costs. Furthermore, they lack a process for compressing the ground soy pulp, resulting in a greater need for refrigerated storage space and thus lower practicality. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a soybean product grinding machine, which solves the problem that existing grinding machines require secondary grinding of soybean residue, increasing additional processes and production costs. Furthermore, the lack of a compression process for the ground soybean residue results in the need for more refrigerated storage space, making it less practical.
[0006] According to an embodiment of this utility model, a soybean product grinding machine includes a cylindrical body. From top to bottom, the body contains an inlet, a grinding device, and a conveying assembly. The grinding device includes a first motor vertically fixedly mounted in the center of the top of the body and a rotating shaft fixedly connected to the output end of the first motor. It also includes a coarse grinding assembly and a fine grinding assembly sequentially mounted within the body and connected to the rotating shaft. The bottom areas of the coarse grinding assembly and the fine grinding assembly are respectively provided with a first guide funnel and a second guide funnel for guiding the flow. The coarse grinding assembly includes a first grinding disc fixedly mounted at the bottom of the inlet. A second grinding disc is rotatably disposed below the grinding disc with a gap. The fine grinding assembly includes a third grinding disc fixedly disposed in the area below the bottom of the coarse grinding assembly. A fourth grinding disc is rotatably disposed below the third grinding disc with a gap. The top center area of both the first and third grinding discs is provided with a feed hole. The rotating shaft passes through the feed hole. The diameter of the feed hole is larger than the diameter of the rotating shaft. The top receiving areas of the two guide funnels are larger than the projected area of the grinding disc. The bottom of the first guide funnel is fixedly connected to the feed hole of the third grinding disc. The bottom of the second guide funnel is fixedly connected to the inlet end of the conveying assembly.
[0007] A cylindrical pressing assembly is also provided on one side of the machine body. The discharge end of the conveying assembly passes through the inner wall of the machine body and is connected to the bottom side wall area of the pressing assembly. A discharge port is also provided below the bottom of the pressing assembly. A lifting compression plate is provided inside the pressing assembly. A pressure plate that can close the discharge port is also provided on the end face of the discharge port. A first filter screen is also provided through the pressure plate. A receiving box is also provided in the area below the bottom of the discharge port.
[0008] Furthermore, the pressing assembly includes a compression cylinder vertically arranged on one side of the machine body. The inner wall of the compression cylinder connected to the machine body is also provided with a feed inlet. The output end of the conveying assembly is located at the feed inlet. A baffle corresponding to the feed inlet is also vertically arranged on the side of the top of the compression plate facing the feed inlet.
[0009] Furthermore, a first electric push rod is vertically provided at the top of the compression cylinder, and a second electric push rod is horizontally provided at the bottom of the machine body. The output end of the first electric push rod is fixedly connected to the top of the compression plate and drives it to rise and fall. An opening is also provided on one side of the machine body adjacent to the discharge port. The pressure plate is provided at the port of the discharge port. The output end of the second electric push rod is driven to be connected to one side of the pressure plate. The second electric push rod drives the pressure plate to pass through the opening to close and open the discharge port.
[0010] Furthermore, the pressure plate has a protruding protrusion on one side of the output end of the second electric push rod that is fixed to it, and the bottom of the discharge port has an inwardly recessed groove on one side of the inner wall. The pressure plate can be fixed in the groove by the protrusion under the drive of the second electric push rod.
[0011] Furthermore, a support frame is provided at the bottom of the first filter screen, and a second filter screen is wrapped on the pressure plate. The second filter screen is a flexible filter screen.
[0012] Furthermore, the first and third grinding discs are identical in structure and are fixedly installed on the inner wall of the machine body, the second and fourth grinding discs are identical in structure and are fixedly installed on the rotating shaft, and the gap between the fourth grinding disc and the third grinding disc is smaller than the gap between the first and second grinding discs.
[0013] Furthermore, the conveying assembly includes a conveying screw and a second motor horizontally disposed in the area below the fine grinding assembly. The second motor is drivenly connected to the conveying screw, and the top of the screw is provided with a through hole and is fixedly connected to the bottom of the second guide funnel.
[0014] Furthermore, the inner wall of the receiving box is also provided with several conveying rollers arranged in parallel and rotating.
[0015] The technical principle of this invention is as follows: Soybean raw materials are fed into the inlet. The raw materials first enter between the first and second grinding discs through the feed hole at the top of the first grinding disc, where they are ground by relative rotation. The initially pulverized soybean residue and some soy milk enter the first feed funnel through the edges of the first and second grinding discs. Since the soybean residue and soy milk are still mixed and relatively moist, no additional water needs to be added. The mixed soybean residue and soy milk then continue to be ground between the third and fourth grinding discs through the feed hole of the third grinding disc. This four-stage grinding device, composed of four grinding discs, can thoroughly grind the soybean raw materials, achieving complete pulverization. After grinding, the soybean residue and soy milk flow through the second feed funnel... The soybean pulp enters the conveying assembly at the bottom of the grinding device. The conveying assembly transports the ground soybean pulp to the briquetting assembly on one side of the machine body. Inside the briquetting assembly, the compression plate compresses the ground soybean pulp, while some of the soybean pulp flows into the receiving box through the first filter screen on the compression plate. As the compression plate presses the soybean pulp into blocks, the original soybean pulp inside is squeezed out and flows into the receiving box through the first filter screen. Finally, the soybean pulp, after being formed into blocks, leaves the briquetting assembly and enters the receiving box. Through the above scheme, the soybean raw materials are thoroughly ground, reducing the secondary grinding process. Furthermore, the soybean pulp is compressed into blocks in the briquetting assembly, making the storage of soybean pulp more convenient and efficient, significantly reducing the refrigeration space required, and facilitating subsequent recycling, thus improving its practicality.

[0031] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The embodiments further illustrate the technical solutions of this utility model.
[0032] like Figures 1 to 5As shown, according to an embodiment of the present invention, a soybean product grinding machine includes a cylindrical body 1. The body 1 contains, from top to bottom, an inlet 2, a grinding device, and a conveying assembly 6. The grinding device includes a first motor 3 vertically fixedly mounted in the central area of the top of the body 1 and a rotating shaft 31 fixedly connected to the output end of the first motor 3. It also includes a coarse grinding assembly 4 and a fine grinding assembly 5 sequentially mounted within the body 1 and connected to the rotating shaft 31. The bottom areas of the coarse grinding assembly 4 and the fine grinding assembly 5 are respectively provided with a first guiding funnel 43 and a second guiding funnel 53 for guiding flow. The coarse grinding assembly 4 includes a first grinding disc 41 fixedly mounted at the bottom of the inlet 2. A second grinding disc 42 is rotatably disposed below the grinding disc 41 with a gap. The fine grinding component 5 includes a third grinding disc 51 fixedly disposed in the area below the bottom of the coarse grinding component 4. A fourth grinding disc 52 is rotatably disposed below the third grinding disc 51 with a gap. The top center area of the first grinding disc 41 and the third grinding disc 51 are also provided with a feed hole. The rotating shaft 31 passes through the feed hole. The diameter of the feed hole is larger than the diameter of the rotating shaft 31. The top receiving area of the two guide funnels is larger than the projected area of the grinding disc. The bottom of the first guide funnel 43 is fixedly connected to the feed hole of the third grinding disc 51. The bottom of the second guide funnel 53 is fixedly connected to the feed end of the conveying component 6.
[0033] A cylindrical pressing assembly 7 is also provided on one side of the machine body 1. The discharge end of the conveying assembly 6 passes through the inner wall of the machine body 1 and is connected to the bottom side wall area of the pressing assembly 7. A discharge port 8 is also provided below the bottom of the pressing assembly 7. A lifting compression plate 72 is provided inside the pressing assembly 7. A pressure plate 76 that can close the discharge port 8 is also provided on the end face of the discharge port 8. A first filter screen 762 is also provided through the pressure plate 76. A receiving box 9 is also provided in the area below the bottom of the discharge port 8.
[0034] Through the aforementioned institutions, such as Figure 1 and Figure 2 As shown, after the bean raw materials are put into the feed port 2, the water outlet 21 releases clean water to assist in grinding and mix with the bean raw materials. The flow rate of clean water can be selected according to the quality and feeding speed of the bean raw materials. The bean raw materials first enter the space between the first grinding disc 41 and the second grinding disc 42 through the feed hole at the top of the first grinding disc 41, and are ground by the relative rotation of the two. The initially crushed bean residue and some soy milk enter the first guide funnel 43 through the edges of the first grinding disc 41 and the second grinding disc 42. Since the bean residue and soy milk are still in a mixed state, the bean residue is relatively moist and no more clean water needs to be added. Then the mixed bean residue and soy milk continue to enter the space between the third grinding disc 51 and the fourth grinding disc 52 through the feed hole of the third grinding disc 51 for grinding. The above four grinding discs are combined into a two-stage grinding device, which can achieve the effect of fully grinding the bean raw materials and completely crushing the bean raw materials.
[0035] After grinding, the soybean residue and soy milk enter the conveying component 6 at the bottom of the grinding device through the second feed funnel 53. The conveying component 6 transports the ground soy milk and soybean residue to the pressing component 7 on one side of the machine body 1. Inside the pressing component 7, the compression plate 72 compresses the ground soybean residue, while some of the soy milk enters the receiving box 9 in advance through the first filter screen 762 on the compression plate 72. When the compression plate 72 presses the soybean residue into blocks, the original soy milk in the soybean residue is squeezed out and enters the receiving box 9 through the first filter screen 762. Finally, the soybean residue leaves the pressing component 7 and enters the receiving box 9 after being formed into blocks. Through the above scheme, the soybean raw materials are fully ground, reducing the secondary grinding process of the soybean raw materials. In addition, the soybean residue is compressed into blocks in the pressing component 7, making the storage of soybean residue more convenient and efficient, and greatly reducing the space occupied by the refrigeration unit. It also facilitates subsequent recycling and improves practicality.
[0036] Furthermore, such as Figure 1 and Figure 2 As shown, the pressing assembly 7 includes a compression cylinder 71 vertically arranged on one side of the machine body 1. The compression cylinder 71 can be rectangular, which makes it easier to stack the pressed soybean residue blocks. The inner wall of the side of the compression cylinder 71 connected to the machine body 1 is also provided with a feed inlet 79. The output end of the conveying assembly 6 is located at the feed inlet 79. When the conveying assembly 6 receives the ground soybean residue and soybean milk mixture, it enters the pressing assembly 7 from the discharge end of the conveying assembly 6 through the feed inlet 79. The top of the compression plate 72 is also vertically provided with a baffle 73 on the side facing the feed inlet 79, which can close the feed inlet 79. When the compression plate 72 descends, the baffle 73 can slowly close the feed inlet 79 to prevent soybean residue from leaking out of the feed inlet 79.
[0037] Furthermore, such as Figure 1 and Figure 2 As shown, a first electric push rod 77 is vertically provided at the top of the compression cylinder 71, and a second electric push rod is horizontally provided at the bottom of the machine body 1. The output end of the first electric push rod 77 is fixedly connected to the top of the compression plate 72 and drives it to rise and fall. An opening 75 is provided on one side of the machine body 1 adjacent to the discharge port. The pressure plate 76 is provided at the port of the discharge port. The output end of the second electric push rod is driven to one side of the pressure plate 76. The second electric push rod drives the pressure plate 76 through the opening 75 to close and open the discharge port.
[0038] Furthermore, such as Figure 1 and Figure 2 as well as Figure 3As shown, the pressure plate 76 has a protruding protrusion 761 extending horizontally on one side relative to the output end of the second electric push rod. The inner wall side corresponding to the bottom of the discharge port has an inwardly recessed groove 74. Under the drive of the second electric push rod, the pressure plate 76 can be fixed in the groove 74 by the protrusion 761. When the second electric push rod drives the pressure plate 76 to move to completely cover the discharge port, the protrusion 761 can overlap in the groove 74, so that it can withstand the pressure of the compression plate 72.
[0039] Furthermore, such as Figure 2 , Figure 3 and Figure 4 as well as Figure 5 As shown, the bottom of the first filter screen 762 is also provided with a support frame 763 to increase the structural strength of the pressure plate 76. The pressure plate 76 is also wrapped with a second filter screen 764. The second filter screen 764 is a flexible filter screen. The second filter screen 764 can be made of cotton. The mesh of the cotton filter screen is smaller and less likely to be blocked by soybean residue. The second filter screen 764 covers and wraps the pressure plate 76 to prevent the first filter screen 762 from being blocked by soybean residue and reducing its filtration of soy milk.
[0040] Furthermore, such as Figure 1 and Figure 2 As shown, the first grinding disc 41 and the third grinding disc 51 are identical mechanisms and are fixedly mounted on the inner wall of the machine body 1 via a bracket 44. The second grinding disc 42 and the fourth grinding disc 52 are identical mechanisms and are fixedly mounted on a rotating shaft 31. The rotating shaft 31 can drive the second and fourth grinding discs 52 to rotate and cooperate with the fixed first grinding disc 41. The third grinding disc 51 grinds the soybean residue. The gap between the fourth grinding disc 52 and the third grinding disc 51 is smaller than the gap between the first grinding disc 41 and the second grinding disc 42. Through the above mechanism setting, the gap distance between the third grinding disc 51 and the fourth grinding disc 52 is reduced, which makes the grinding of soybean residue more fine.
[0041] Furthermore, such as Figure 1 and Figure 2 As shown, the bottom of the fourth grinding disc 52 is also fixedly provided with a base 32, and the bottom of the rotating shaft 31 protrudes from the bottom of the fourth grinding disc 52. The protruding end of the rotating shaft 31 is rotatably connected to the base 32 by a bearing. The edge of the base 32 is also provided with several stabilizing frames 33 in a radial pattern. The stabilizing frames 33 extend from the edge of the base 32, pass through the inner wall of the second feed funnel 53, and connect to the inner wall of the machine body 2. The cross-section of the stabilizing frame 33 can be arc-shaped or triangular, so that the soybean residue raw material falling on the stabilizing frame 33 cannot remain on its surface in large quantities. In summary, the base 32 and the stabilizing frame 33 provide support for the rotating shaft 31, so that the weight of the first motor 3 borne by the first and third grinding discs is completely distributed, and the first motor 3 is prevented from being damaged after the working time is extended.
[0042] Furthermore, such as Figure 1 and Figure 2 As shown, the conveying assembly 6 includes a conveying screw 61 and a second motor 62 horizontally disposed below the fine grinding assembly 5. The second motor 62 is driven and connected to the conveying screw 61. The top of the conveying screw 61 is provided with a through hole for feeding and is fixedly connected to the bottom of the second guide funnel 53 located at the bottom of the fine grinding assembly 5. The through hole at the top of the conveying screw 61 is closed to prevent leakage. The raw material of soybean residue mixed with soybean milk enters the conveying screw 61 from the bottom of the second guide funnel 53 and is then conveyed by the conveying screw 61 to the pressure plate 76 in the pressing assembly 7. After a certain amount of soybean residue has accumulated, the conveying screw 61 can stop working. The compression plate 72 begins to lower under the drive of the first electric push rod 77. At the same time, the baffle 73 disposed on the pressure plate 76 slowly closes the discharge end of the conveying screw 61 as the compression plate 72 descends to prevent soybean residue from entering the upper surface of the compression plate 72.
[0043] Furthermore, such as Figure 1 and Figure 2 As shown, the inner wall of the receiving box 9 is also provided with several conveying rollers arranged in parallel and rotating. When the second electric push rod drives the pressure plate 76 to contract, the pressed soybean residue falls onto the transmission rollers and is conveyed to another location.
[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
