[0001] This utility model relates to the field of earthworm protein processing technology, and in particular to a multifunctional liquid nitrogen device for earthworm protein production. Background Technology

[0002] Earthworm protein refers to a class of biologically active protein components extracted and isolated from earthworms. It possesses beneficial pharmacological effects such as fibrinolysis, anticoagulation, and blood pressure reduction. Modern research indicates that earthworm protein has certain therapeutic effects in dissolving blood clots, improving blood circulation, and protecting the cardiovascular system, and it is frequently used in pharmaceutical and health product development. Due to its natural origin and multiple health benefits, earthworm protein has received widespread attention in the biomedical field.

[0003] In the production of earthworm protein, the earthworm raw material needs to be quick-frozen using a liquid nitrogen device so that it can be better ground in subsequent work. However, the traditional quick-freezing and grinding steps are independent of each other. This causes the temperature to change when the earthworm raw material is transferred to the grinding equipment after quick-freezing, which causes the earthworm protein components in the raw material to degrade and denature, affecting the final quality of the product.

[0004] Therefore, it is necessary to design a multifunctional liquid nitrogen device for the production of earthworm protein. Utility Model Content

Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0022] Example: A multifunctional liquid nitrogen device for producing earthworm protein, such as... Figures 1-4 As shown, the system includes a processing cabinet 1, a cabinet door 2, a hopper 3, a hopper plug 301, a liquid inlet 4, a connecting pipe 5, a liquid nitrogen nozzle 6, a grinding frame 7, a connecting rod 8, a grinding rod 9, a clamping mechanism, and a driving mechanism. The processing cabinet 1 has a cabinet door 2 rotatably connected to one side, and a hopper 3 is fixedly connected to the top of the processing cabinet 1. A hopper plug 301 for sealing its opening is movably connected to the hopper 3. The neck of the hopper 3 extends into the processing cabinet 1 and is equipped with a liquid nitrogen nozzle 6. A liquid inlet 4 is located near the hopper 3 in the processing cabinet 1, and the liquid inlet 4 is connected to the connecting pipe... 5 is connected to the liquid nitrogen nozzle 6. The processing cabinet 1 is equipped with a clamping mechanism. The clamping mechanism is movably connected to the grinding frame 7. The grinding frame 7 is rotatably connected to the connecting rod 8. The connecting rod 8 is fixedly connected to the grinding rod 9. The bottom of the processing cabinet 1 is equipped with a drive mechanism for driving the connecting rod 8 to rotate. The grinding frame 7 is located below the feeding hopper 3. The bottom of the grinding frame 7 is equipped with rough texture. The design of the rough texture in the grinding frame 7 can further enhance the friction between the grinding rod 9 and the grinding frame 7, thereby improving the grinding efficiency and grinding quality of the device.

[0023] like Figure 1 As shown, a sealing gasket 201 is fixedly connected to the side of the cabinet door 2 facing the processing cabinet 1. The design of the sealing gasket 201 can seal the gap between the cabinet door 2 and the processing cabinet 1, thereby preventing cold air inside the device from leaking out and affecting the quick-freezing efficiency of the device, and effectively improving the sealing and stability of the device.

[0024] like Figure 1 As shown, the cabinet door 2 is equipped with a viewing window 202 for observing the internal situation of the processing cabinet 1. The design of the viewing window 202 makes it convenient for staff to observe the internal situation of the device, so that staff can discover and solve problems in a timely manner, which is conducive to improving work efficiency and work quality.

[0025] like Figure 2As shown, the clamping mechanism includes an electric push rod 10 and a clamp 11. Electric push rods 10 are provided on opposite sides inside the processing cabinet 1. The movable rod of the electric push rod 10 is fixedly connected to the clamp 11. The two clamps 11 are close to each other to clamp and fix the grinding frame 7. When the electric push rod 10 is activated, the movable rod of the electric push rod 10 retracts inward, causing the clamp 11 connected to the electric push rod 10 to move away from the grinding frame 7, thereby releasing the clamping and fixing of the grinding frame 7.

[0026] like Figure 3 As shown, the drive mechanism includes a cylinder 12, a mounting plate 13, a motor 14, and a hexagonal rod 15. The cylinder 12 is installed at the bottom of the processing cabinet 1. The piston rod of the cylinder 12 is connected to the mounting plate 13. The motor 14 is installed on the mounting plate 13. The output shaft of the motor 14 is connected to the hexagonal rod 15. A slot is provided on the connecting rod 8 for the hexagonal rod 15 to extend into. When the motor 14 is started, the motor 14 drives the output shaft to rotate. The output shaft of the motor 14 drives the hexagonal rod 15 to rotate, which in turn drives the connecting rod 8 and the grinding rod 9 connected to it to rotate.

[0027] like Figure 3 As shown, a telescopic limit rod 16 is fixedly connected to the bottom of the processing cabinet 1. The movable end of the telescopic limit rod 16 is fixedly connected to the mounting plate 13. The design of the telescopic limit rod 16 can provide guidance for the movement of the mounting plate 13, prevent the mounting plate 13 from shifting during the movement, and ensure that the hexagonal rod 15 connected to the motor 14 can be stably inserted into the slot of the connecting rod 8, thus promoting the stable operation of the device.

[0028] This device is used in the production and processing of earthworm protein. During use, the external liquid nitrogen input device is connected to the device's inlet 4. Then, the operator pulls the bucket stopper 301 upwards, opening the discharge hopper 3. An appropriate amount of earthworm raw material is then added to the discharge hopper 3. As the earthworm raw material falls through the neck of the discharge hopper 3 into the grinding frame 7, the liquid nitrogen input device injects liquid nitrogen from the inlet 4 into the connecting pipe 5 and its connected liquid nitrogen nozzle 6. This allows the liquid nitrogen to be sprayed onto the falling earthworm raw material through the liquid nitrogen nozzle 6, thus rapidly freezing the material. Afterwards, the bucket stopper 301 is returned to its original position, sealing the opening of the discharge hopper 3 again. Once completed, the cylinder 12 is activated, extending its piston rod outwards, which in turn drives the mounting plate 13. The upward movement causes the motor 14 on the mounting plate 13 to move upward as well, allowing the hexagonal rod 15 connected to the motor 14 to extend into the slot opened in the connecting rod 8. The motor 14 is then started, driving the output shaft to rotate. The output shaft of the motor 14 drives the hexagonal rod 15 to rotate, which in turn drives the connecting rod 8 and its connected grinding rod 9 to rotate. This causes the grinding rod 9 to grind the earthworm material in the grinding frame 7 until the grinding is completed. Then, the staff opens the cabinet door 2 and starts the electric push rod 10. The movable rod of the electric push rod 10 retracts inward, causing the clamp 11 connected to the electric push rod 10 to move away from the grinding frame 7, thereby releasing the clamping and fixing of the grinding frame 7. The staff can then remove it and carry out the subsequent pouring work, thus completing the work.
