Description

Technical Field

[0001] This utility model relates to the field of soybean milk production technology, specifically to a horizontal screw conveyor system for soybean milk production. Background Technology

[0002] In the soymilk production process, raw materials and water are mixed in a feeding hopper. The mixed material then enters a grinder for grinding, forming the soymilk base. Since soybeans themselves contain a large amount of fiber, i.e., soy pulp, a horizontal screw centrifuge is usually used to separate the ground material into solid and liquid components. The horizontal screw centrifuge separates the material into soy pulp and a protein-containing liquid. The protein-containing liquid is then transported through pipelines to the next production process, while the separated soy pulp is processed. However, the separated soy pulp still contains a significant amount of protein, and directly processing the soy pulp would result in a waste of protein. Utility Model Content

[0003] In view of this, the present invention provides a horizontal screw conveyor system for soy milk production to solve the problem that there is still a lot of protein in the separated soybean residue, and that directly processing the soybean residue would cause protein waste.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] The following is combined Figure 1 The following describes embodiments of the present invention.

[0032] According to an embodiment of the present invention, a horizontal screw conveyor system for soy milk production is provided, comprising a grinding structure 1, a first centrifugal structure 4, a second centrifugal structure 6, and a liquid storage structure 8.

[0033] Specifically, the grinding structure 1 is connected to the raw material bin 2 and the first liquid pipe 3. The first centrifugal structure 4 is connected to the grinding structure 1, and its outlet is connected to the first base material pipe 5. The material conveyed from the grinding structure 1 to the first centrifugal structure 4 is separated into a first base material and a first intermediate material. The base material enters the first base material pipe 5 through the outlet of the first centrifugal structure 4. The second centrifugal structure 6 is connected to the first centrifugal structure 4. The second centrifugal structure 6 is used to centrifuge the first intermediate material to separate it into a second base material and a second intermediate material. The outlet of the second centrifugal structure 6 is connected to the second base material pipe 7. The liquid storage structure 8 is connected to both the first liquid pipe 3 and the second base material pipe 7.

[0034] In this embodiment, the grinding structure 1 is a coffee grinder, the raw material hopper 2 stores soybean raw materials, the liquid in the first liquid pipe 3 is hot water, the hot water and soybean raw materials are mixed and then enter the coffee grinder for grinding to form material, which is the soybean milk base. After grinding, the material enters the first centrifugal structure 4. The first centrifugal structure 4 can centrifuge and separate the material into the first base material and the first intermediate material. The first base material is a liquid product containing a large amount of protein. Since the first base material basically does not contain soybean residue, the first base material will enter the first base material pipe 5 from the discharge port of the first centrifugal structure 4 and enter the next production process along the first base material pipe 5. The first intermediate material is soybean residue. The first intermediate material after centrifugation by the first centrifugal structure 4 still has a certain amount of moisture and still has a lot of protein. The first centrifugal structure 4 has a first slag discharge port (not shown). The first slag discharge port is connected to the feed port of the second centrifugal structure 6 through a pipeline. The first intermediate material enters the second centrifugal structure 6 through the first slag discharge port and the pipeline. The second centrifugal structure 6 centrifuges the first intermediate material, separating it into a second base material and a second intermediate material. The second base material is a liquid product with low protein content. To avoid reducing the overall protein content of the product, the second base material cannot directly enter the next production process. The outlet of the second centrifugal structure 6 is connected to the liquid storage structure 8 through the second base material pipe 7. The second base material enters the liquid storage structure 8 through the outlet and along the second base material pipe 7. The liquid storage structure 8 is connected to the first liquid pipe 3. The second base material will be mixed with the soybean raw material through the first liquid pipe 3 and then re-enter the grinding structure 1. The second intermediate material is soybean residue. After centrifugation by the second centrifugal structure 6, the second intermediate material still contains a small amount of protein, but the protein obtained by further centrifugation is far lower than the labor cost. Therefore, the second intermediate material will be discharged from the second slag discharge port (not shown) of the second centrifugal structure 6 and recycled.

[0035] Preferably, the first centrifugal structure 4 and the second centrifugal structure 6 are horizontal screw centrifuges, and the liquid storage structure 8 is a hot water tank.

[0036] By setting a second centrifugal structure 6, the first intermediate material separated by the first centrifugal structure 4 can be centrifuged again. The second centrifugal structure 6 can recover a large amount of protein in the first intermediate material, effectively improving the utilization of protein and avoiding protein waste.

[0037] In one embodiment, a transition component is also included. The transition component includes an intermediate material buffer tank 9 and a buffer tube 10. The buffer tube 10 includes a first buffer tube 1001 and a second buffer tube 1002. The intermediate material buffer tank 9 is connected to the first centrifugal structure 4 through the first buffer tube 1001. The intermediate material buffer tank 9 is used to contain the first intermediate material. The intermediate material buffer tank 9 is connected to the second centrifugal structure 6 through the second buffer tube 1002.

[0038] In this embodiment, as Figure 1 As shown, the inlet of the intermediate material buffer tank 9 is connected to the first slag discharge port of the first centrifugal structure 4 through the first buffer pipe 1001, and the outlet of the intermediate material buffer tank 9 is connected to the second slag discharge port of the second centrifugal structure 6 through the second buffer pipe 1002. The intermediate material buffer tank 9 is used to store the first intermediate material to prevent the second centrifugal structure 6 from becoming clogged due to a large amount of the first intermediate material entering the second centrifugal structure 6.

[0039] In one embodiment, the transition assembly further includes a first detection structure 11 and a buffer pump 12 disposed in the intermediate material buffer tank 9. The buffer pump 12 is disposed in the second buffer pipe 1002, and the first detection structure and the buffer pump 12 are respectively connected to the control mechanism via signal connection.

[0040] In this embodiment, as Figure 1 As shown, a first detection structure 11 is provided inside the intermediate material buffer tank 9. Preferably, the first detection structure is a liquid level detector. The first detection structure 11 is signal-connected to a control mechanism (not shown). The first detection structure 11 can transmit real-time liquid level information in the intermediate material buffer tank 9 to the control mechanism. The control mechanism can control the pumping speed of the buffer pump 12 to adjust the liquid level in the intermediate material buffer tank 9. When the liquid level in the intermediate material buffer tank 9 is high, the control mechanism controls the buffer pump 12 to increase the pumping speed, thereby increasing the flow rate of the first intermediate material in the second buffer pipe 1002 and reducing the liquid level in the intermediate material buffer tank 9. When the liquid level in the intermediate material buffer tank 9 is low, the control mechanism controls the buffer pump 12 to decrease the pumping speed, thereby reducing the flow rate of the first intermediate material in the second buffer pipe 1002 and preventing leakage or blockage of the second centrifugal structure 6.

[0041] Preferably, the control mechanism is a PLC controller.

[0042] In one embodiment, it further includes: a second intermediate material buffer structure 13, which is connected to the second centrifugal structure 6, the second intermediate material buffer structure 13 is used to contain the second intermediate material, and the second intermediate material buffer structure 13 is connected to the recycling mechanism through the second intermediate material discharge pipe 14.

[0043] In this embodiment, as Figure 1 As shown, the second intermediate material buffer structure 13 is connected to the second slag discharge port of the second centrifugal structure 6 via a pipeline. The second intermediate material buffer structure 13 is used to contain the second intermediate material. The discharge port of the second intermediate material buffer structure 13 is connected to the recovery mechanism via a pipeline. The second intermediate material enters the second intermediate material buffer structure 13 through the second slag discharge port and the pipeline, and then enters the recovery mechanism through the discharge port of the second intermediate material buffer structure 13 and the pipeline. The second intermediate material buffer structure 13 can store the second intermediate material and prevent the second intermediate material from clogging or overflowing.

[0044] In one embodiment, a pressure detection structure 15 is provided on the second intermediate material discharge pipe 14. The pressure detection structure 15 is connected to the control mechanism via signal. The pressure detection structure 15 is used to detect the pressure inside the second intermediate material discharge pipe 14. The second intermediate material buffer structure 13 is connected to the second liquid pipe 16. A first control valve 17 is provided on the second liquid pipe 16. The first control valve 17 is connected to the control mechanism via signal.

[0045] In this embodiment, as Figure 1 As shown, a pressure detection structure 15 is provided on the second intermediate material discharge pipe 14. The pressure detection structure 15 can detect the pressure inside the second intermediate material discharge pipe 14 and transmit the real-time pressure information to the control mechanism. The control mechanism can determine whether the second intermediate material discharge pipe 14 is blocked due to the second intermediate material being too dry based on the pressure information. The second intermediate material buffer structure 13 is connected to the second liquid pipe 16. The other end of the second liquid pipe 16 is connected to a cold water tank. The second liquid pipe 16 contains cold water, which can enter the second intermediate material buffer structure 13 and mix with the second intermediate material to avoid the second intermediate material discharge pipe 14 from being blocked due to the second intermediate material being too dry. A first control valve 17 is installed on the second liquid pipe 16. If the pressure in the second intermediate material outlet pipe 14 is detected to be too high, the control mechanism controls the first control valve 17 to open, so that the cold water in the second liquid pipe 16 flows into the second intermediate material buffer structure 13 and enters the second intermediate material outlet pipe 14 to mix with the second intermediate material, thereby diluting it and relieving the blockage. When the pressure in the second intermediate material outlet pipe 14 decreases, the control mechanism controls the first control valve 17 to close.

[0046] By setting up a pressure detection structure 15, a second liquid pipe 16, and a first control valve 17, the control mechanism can control the first control valve 17 to open or close according to the pressure information detected by the pressure detection structure 15, so that the cold water in the second liquid pipe 16 enters the second intermediate material buffer structure 13 and the second intermediate material outlet pipe 14 to dilute the second intermediate material and avoid the second intermediate material outlet pipe 14 from being blocked due to the second intermediate material being too dry.

[0047] In this embodiment, as Figure 1 As shown, a discharge pump 18 is provided inside the second intermediate material buffer structure 13. The discharge pump 18 can send the second intermediate material inside the second intermediate material buffer structure 13 into the second intermediate material discharge pipe 14.

[0048] In one embodiment, a second detection structure 19 is provided inside the liquid storage structure 8. The liquid storage structure 8 is connected to the liquid supply mechanism through a liquid supply pipe 20. A second control valve 21 is provided on the liquid supply pipe 20. The second detection structure 19 and the second control valve 21 are respectively connected to the control mechanism via signal.

[0049] In this embodiment, as Figure 1 As shown, the liquid storage structure 8 stores hot water. A second detection structure 19, a liquid level detector, is installed within the liquid storage structure 8 to detect the liquid level. A second base material enters the liquid storage structure 8 through the second base material pipe 7 and mixes with the hot water. The resulting liquid then enters the first liquid pipe 3. The supply pipe 20 is a hot water pipe, and the supply mechanism is a hot water output mechanism. A second control valve 21 is installed on the supply pipe 20. The second detection structure 19 transmits the real-time liquid level information of the liquid storage structure 8 to the control mechanism. The control mechanism controls the opening of the second control valve 21 based on the liquid level information, thereby controlling the flow rate of hot water to ensure the stability of the liquid level within the liquid storage structure 8.

[0050] In one embodiment, the inlet and outlet of the first centrifugal structure 4 and the second centrifugal structure 6 are respectively provided with flexible buffer tubes 22.

[0051] In this embodiment, as Figure 1 As shown, the inlet of the first centrifugal structure 4 is connected to the grinding structure 1 via a flexible buffer tube 22, and the outlet of the first centrifugal structure 4 is connected to the first base material tube 5 via the flexible buffer tube 22. The inlet of the second centrifugal structure 6 is connected to the second buffer tube 1002 via the flexible buffer tube 22, and the outlet of the second centrifugal structure 6 is connected to the second base material tube 7 via the flexible buffer tube 22. The flexible buffer tube 22 can reduce the vibration generated by the first centrifugal structure 4 and the second centrifugal structure 6 during operation, preventing the pipe joints from loosening due to excessive vibration generated by the first centrifugal structure 4 and the second centrifugal structure 6 during operation.

[0052] In one embodiment, the system further includes a feeding hopper 23. A screw pump 24 is installed at the outlet of the feeding hopper 23. The screw pump 24 is connected to the grinding structure 1 via a material pipe 25. The first liquid pipe 3 and the raw material hopper 2 are respectively connected to the feeding hopper 23.

[0053] In this embodiment, as Figure 1 As shown, the feeding bin 23 is connected to the first liquid pipe 3 and the raw material bin 2 respectively. The bean raw materials in the raw material bin 2 and the liquid in the first liquid pipe 3 will enter the feeding bin 23 for mixing. The mixed material will be transported to the grinding structure 1 for grinding through the screw pump 24 and the material pipe 25.

[0054] In this embodiment, as Figure 1 As shown, a centrifugal pump 26 is installed on the first liquid pipe 3. The centrifugal pump 26 can send the liquid in the liquid storage structure 8 into the first liquid pipe 3.
