Description

Technical Field

[0001] This utility model relates to the technical field of soybean product processing equipment, specifically to a wet soybean grinding and pulping equipment. Background Technology

[0002] In the process of making soy products, soaked soybeans need to be ground into soy milk. For current soy milk grinding equipment, during the grinding process, the soaked soybeans are placed in a hopper at the top of the grinder and gradually fed into the grinder through the hopper. This feeding method is prone to clogging, meaning that the soybeans cannot enter the grinder smoothly and clogging is likely to occur during the feeding process. In addition, it requires manual draining of the soaked soybeans before loading them into the hopper, which increases the workload.

[0003] The inventor of this utility model previously developed a negative pressure bean-feeding grinding and pulping device. This device uses a vacuum pump to draw soaked soybeans into a water-bean storage tank, and then uses airflow to suck the soaked and drained soybeans into the tank. Because of this principle, the water-bean storage tank cannot simultaneously suck and discharge soybeans; the soybeans must be airflowed before grinding can begin. This prevents continuous bean supply to the grinder, hindering production efficiency. Furthermore, to ensure the water-bean storage tank can hold a large quantity of soybeans for subsequent grinding, it needs to be very large, resulting in a large size and weight for the entire grinding device. Additionally, the need for sufficient negative pressure to draw in the soaked soybeans leads to significant power consumption in creating the vacuum in the water-bean storage tank, making the entire grinding device relatively power-intensive.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In one embodiment, a wet grinding and pulping device is provided, such as... Figure 1-2 As shown, the wet soybean grinding and pulping equipment includes a frame 1, on which a soybean crusher 2 and a first grinder 3 are mounted. A soybean paste transfer device is provided between the soybean crusher 2 and the first grinder 3. The soybean crusher 2 is used to crush the soybeans to obtain soybean paste, and the soybean paste transfer device is used to transfer the soybean paste to the first grinder 3. The first grinder 3 then grinds the soybean paste to obtain soybean milk. A water-soybean separation device 4 is also provided above the soybean crusher 2 to separate the water from the wet soybeans. This wet soybean grinding... The pulping equipment also includes a water-bean temporary storage tank 5 located above the water-bean separation device 4. The water-bean temporary storage tank 5 is used to temporarily store the mixture of water and wet beans. The water-bean temporary storage tank 5 is provided with a water-bean inlet 51 and a flushing outlet 52. The water-bean inlet 51 is connected to a water-bean conveying device through a water-bean conveying pipe. The water-bean conveying device transports the wet beans to the water-bean temporary storage tank 5 by water transport through the water-bean conveying pipe. The flushing outlet 52 is connected to a flushing pipe 55. Water is flushed into the water-bean temporary storage tank 5 through the flushing pipe 55 to promote the downward flow of wet beans.

[0029] Combination Figure 3 As shown, the soaked bean conveying device may include a wet bean hopper 54, in which soaked beans are stored. A water-bean conveying pipe 53 and a bean-transporting water pipe 56 are connected to the bottom of the wet bean hopper 54. Opening the gate at the bottom of the wet bean hopper 54 allows the wet beans to flow downwards, and water continuously enters through the bean-transporting water pipe 56. The mixture of water and wet beans is transported through the water-bean conveying pipe 53 to the water-bean inlet 51, and then into the water-bean temporary storage tank 5. This is just one specific embodiment of the water-bean conveying device; other devices that transport wet beans by water can also be used.

[0030] Furthermore, the wet grinding and pulping equipment is equipped with a pulse solenoid valve (not shown in the figure) on the flushing pipe 55. The pulse solenoid valve can be installed at the end of the flushing pipe 55 so that the pulse solenoid valve can be opened and closed continuously by electrical control to perform pulse flushing in the water bean storage tank 5, which can better promote the downward flow of wet beans and avoid inputting too much clean water.

[0031] Furthermore, such as Figure 1-2 and Figure 4As shown, the wet soybean grinding and pulping equipment is equipped with a common water supply pipe 6 and a water storage tank 7 on the frame 1. One end of the common water supply pipe 6 is connected to a water source for supplying clean water, and the other end is equipped with a valve (not shown in the figure) as a reserved interface. The water storage tank 7 is connected to the common water supply pipe 6 through an inlet pipe 71. An inlet control valve (not shown in the figure) is installed on the inlet pipe 71. The inlet control valve can be a solenoid valve or a pneumatic valve located at the end of the inlet pipe 71. Opening the inlet control valve allows clean water to be temporarily supplied to the water storage tank 7. The bottom of the water storage tank 7 is connected to the inlet of the soybean crusher 2 through a first outlet valve 72, a first outlet flow meter 73, and a first outlet pipe 74. This is used to directly supply a certain amount of water to the soybean crusher 2 when it is initially crushing the wet soybeans, so as to avoid the soybean paste being too thick and sticking to the wall. The first outlet flow meter 73 can measure the supply of clean water and provide a reference for the ratio of wet soybeans to clean water. The bottom of the water storage tank 7 also has a reserved interface, where a valve (not shown in the figure) is installed for backup.

[0032] Furthermore, such as Figure 1-2 and Figure 4 As shown, the soybean paste transfer device in the wet soybean grinding and pulping equipment includes a soybean paste storage tank 21 and a first pumping device. The outlet of the soybean crusher 2 is connected to the soybean paste storage tank 21 for temporarily storing soybean paste. The outlet of the soybean paste storage tank 21 is connected to the inlet of the first grinder 3 through the first pumping device. The first pumping device includes a first pumping pump 22 and a first pumping pipe 23. The inlet of the first pumping pump 22 is connected to the bottom of the soybean paste storage tank 21, and the outlet of the first pumping pump 22 is connected to the first pumping pipe 23. The end of the first pumping pipe 23 is connected to the inlet of the first grinder 3, so that the first pumping device can pump the soybean paste in the soybean paste storage tank 21 to the first grinder 3. A first branch pipe 24 is provided on the first pumping pipe 23, which connects to the soybean paste storage tank 21. A first regulating valve 25 is provided on the first branch pipe 24. Since the lifting capacity of the first pumping pump 22 and the throughput of the first grinder 3 are not necessarily the same, and the consistency of soybean paste is also different when different concentrations of soybean paste are required, the first branch pipe 24 is set to return to the soybean paste storage tank 21. By adjusting the opening of the first regulating valve 25 on the first branch pipe 24, the amount of soybean paste pumped by the first pumping device returning to the soybean paste storage tank 21 can be controlled, that is, the amount of soybean paste pumped by the first pumping pump 22 entering the first grinder 3 can be controlled. This can prevent the flow rate of soybean paste pumped by the first pumping pump 22 from being greater than the throughput of the first grinder 3, which would cause blockage, and can also adjust the consistency of soybean paste.

[0033] In addition, a first soybean residue temporary storage box 31 is provided on the frame 1. The soybean residue outlet of the first grinder 3 is connected to the first soybean residue temporary storage box 31, which temporarily stores the soybean residue produced by the first grinder 3.

[0034] Furthermore, such as Figure 1-2 and Figure 4 As shown, the wet soybean grinding and pulping equipment also includes a second grinder 8 and a second soybean residue storage tank 81. The second grinder 8 is used for secondary grinding. The outlet of the first soybean residue storage tank 31 is connected to the inlet of the second grinder 8 through a second pumping device. The second pumping device lifts and transports the soybean residue in the first soybean residue storage tank 31 to the second grinder 8. The soybean residue outlet of the second grinder 8 is connected to the second soybean residue storage tank 81, which is used to temporarily store the soybean residue produced by the second grinder 8. The bottom of the water storage tank 7 is connected to the first soybean residue storage tank 31 through a second water outlet valve 75, a second water outlet flow meter 76, and a second water outlet pipe 77. The second water outlet valve 75 is an electrically controlled valve or a pneumatic valve. The second water outlet pipe 77 is used to add a certain amount of clean water to the first soybean residue storage tank 31. This serves two purposes: firstly, to dilute the soybean residue in the first soybean residue storage tank 31 for easier lifting; and secondly, to add a certain proportion of water to the soybean residue for grinding into soybean pulp.

[0035] like Figure 1-2 and Figure 4 As shown, the second pumping device includes a second pumping pump 32 and a second pumping pipe 33. The second pumping pipe 33 has a second branch pipe 34 connected to the first soybean residue storage tank 31. The second branch pipe 34 is equipped with a second regulating valve 35. Similarly, by setting the second branch pipe 34, a portion of the soybean residue is diverted to the first soybean residue storage tank 31. By adjusting the opening of the second regulating valve 35, the amount of soybean residue input to the second grinder 8 can be matched with the throughput of the second grinder 8, avoiding blockage. The outlet of the second soybean residue storage tank 81 is connected to a third pumping device, which includes a third pumping pump 82 and a third pumping pipe 83. The third pumping pipe 83 has a third branch pipe 84 connected to the second soybean residue storage tank 81. The third branch pipe 84 is equipped with a third regulating valve 85. The third pumping pipe 83 is connected to a soybean residue separating mill (not shown in the figure). The soybean residue is dried by the soybean residue separating mill. During the drying process, the soybean milk produced from the soybean residue separating mill can be reused. By setting a third branch pipe 84 to return to the second soybean residue temporary storage box 81, and by adjusting the opening of the third regulating valve 85, the amount of soybean residue input to the soybean residue separator is matched with the throughput of the soybean residue separator.

[0036] Furthermore, the soybean paste storage tank 21, the first soybean residue storage tank 31, and the second soybean residue storage tank 81 in the wet soybean grinding and pulping equipment are each equipped with a screw conveyor mechanism. Each screw conveyor mechanism can be connected by a coupling, so that it can be driven by a single motor. Each screw conveyor mechanism stirs and pushes the materials in the soybean paste storage tank 21, the first soybean residue storage tank 31, and the second soybean residue storage tank 81, so that the solid materials are dispersed and suspended for pumping out.

[0037] Specifically, the following methods can be adopted: Figure 10 The spiral conveying mechanism 9 shown includes a rotating shaft 91, with multiple radial support rods 92 along the rotating shaft 91. A first ribbon-shaped spiral blade 93 and a second ribbon-shaped spiral blade 94 are mounted on the support rods 92. The first ribbon-shaped spiral blade 93 is fitted inside the second ribbon-shaped spiral blade 94. The lower parts of the soybean paste storage box 21, the first soybean residue storage box 31, and the second soybean residue storage box 81 are semi-cylindrical. The second ribbon-shaped spiral blades of each spiral conveying mechanism are matched to the size of the lower parts of the soybean paste storage box 21, the first soybean residue storage box 31, and the second soybean residue storage box 81. The first ribbon-shaped spiral blades 93 and the second ribbon-shaped spiral blades 94 serve to stir the materials and push the materials towards the outlet at the end of the corresponding storage box.

[0038] Furthermore, such as Figure 5-6 As shown, the first soybean residue storage box 31 has an outward protrusion 311 on the upper front side to increase its capacity. The soybean paste storage box and the second soybean residue storage box also have this structure. A receiving port 312 is provided on one side of the top of the first soybean residue storage box 31, and the slag outlet 32 ​​of the first grinder 3 is located at the corresponding position of the receiving port 312. The soybean paste storage box and the second soybean residue storage box also have receiving ports on one side of the top.

[0039] Furthermore, in combination Figure 7-9 As shown, the water-bean separation device 4 in the wet soybean grinding and pulping equipment includes a water-bean separation cylinder 41. The water-bean separation cylinder 41 has an inlet 411, and the bottom of the water-bean temporary storage tank 5 has a bean discharge hole, connecting the water-bean separation cylinder 41 to the water-bean temporary storage tank 5. A soybean conveying mechanism is installed inside the water-bean separation cylinder 41. A water-permeable screen 412 is installed on the bottom surface of the water-bean separation cylinder 41, and a drain hopper 42 is installed at the bottom of the water-bean separation cylinder 41. Water from the wet soybeans flows out through the water-permeable screen 412 and enters the drain hopper 42. An outlet is located at the bottom of the drain hopper 42, through which a pipeline can be connected to drain the water. A bean outlet 413 is located at the end of the water-bean separation cylinder 41, and a soybean conveying mechanism 414 is installed inside the water-bean separation cylinder 41. Figure 7-9 As shown, the soybean conveying mechanism 414 is a screw conveyor mechanism, which includes a rotating shaft with screw blades adapted to the water-soybean separation cylinder 41. The screw blades can quickly push the drained soybeans towards the soybean outlet 413. The water-soybean separation device 4 also includes a motor 43 and a gearbox 44, which drive the soybean conveying mechanism 414 to rotate, and transport the drained soybeans to the soybean outlet 413 and into the soybean crusher 2 for crushing.

[0040] In one specific embodiment of this wet soybean grinding and pulping equipment, combined with Figure 1-10As shown, its working method is as follows: When the wet soybean grinding and pulping equipment is working, water is supplied to the bottom of the water soybean storage tank 5 through the soybean conveying water pipe 56. At the same time, the wet soybean hopper 54 discharges the wet soybeans, so that the wet soybeans are transported to the water soybean storage tank 5 by water transport. The water and wet soybeans in the water soybean storage tank 5 flow into the water soybean separation device 4. At this time, the motor 43 of the water soybean separation device 4 is started. The water will flow out from the drain screen 412 at the bottom of the water soybean separation cylinder 41 and be discharged through the outlet at the bottom of the drain hopper 42. The drained wet soybeans are then transported to the soybean crusher 2 through the soybean conveying mechanism 414. The soybean crusher 2 is started to crush the wet soybeans. At the same time, a certain amount of clean water is supplied to the soybean crusher 2 through the first water outlet pipe 74 to prevent the soybean paste in the soybean crusher 2 from sticking to the wall. The soybean paste processed by the soybean crusher 2 is transported to the soybean paste storage box 21 for temporary storage. The first pump 22 is started, and the soybean paste is lifted to the first grinder 3 through the first pumping pipe 23. The first grinder 3 grinds the soybean paste to produce soybean milk and soybean residue. The soybean milk is collected as a finished or semi-finished product, and the soybean residue enters the first soybean residue storage tank 31. A certain amount of clean water is added to the first soybean residue storage tank 31 through the second water outlet pipe 77. The second pump 32 is started, and the soybean residue in the first soybean residue storage tank 31 is lifted to the second grinder 8 through the second pumping pipe 33. The second grinder 8 grinds the soybean residue a second time. The soybean milk is collected as a finished or semi-finished product, and the soybean residue enters the second soybean residue storage tank 81. The third pump 82 is started, and the soybean residue in the second soybean residue storage tank 81 is transported to the soybean residue separation mill through the third pumping pipe 83. The separated soybean milk can be reused, and the soybean residue is used for food processing or feed.
