[0002] In the seafood processing industry, rapid freezing is a crucial step in extending shelf life and maintaining quality. Traditional quick-freezing equipment is inefficient, unable to perform continuous freezing operations, and cannot meet the demands of large-scale seafood processing. During the quick-freezing process, nitrogen gas generated from liquid nitrogen vaporization, if not promptly discharged, will accumulate in the workshop, increasing nitrogen concentration and posing a threat to worker health. Furthermore, traditional equipment has shortcomings in preventing containers from freezing together, reducing friction during movement, and preventing nitrogen leakage. These issues restrict the quality and efficiency of seafood quick-freezing, hindering the development of the seafood processing industry.

[0003] Therefore, it is necessary to provide a new quick-freezing device for aquatic products to solve the above-mentioned technical problems. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1-4 ,in, Figure 1 A three-dimensional structural diagram of the quick-freezing device for aquatic products provided by this utility model; Figure 2 A cross-sectional structural schematic diagram of the quick-freezing device for aquatic products provided by this utility model; Figure 3 A cross-sectional structural schematic diagram of the quick-freezing device for aquatic products provided by this utility model; Figure 4 A schematic diagram of the container structure provided by this utility model is shown below. Figure 4 As shown: where a is the width of the container, b is the height of the container, and c is the length of the container.

[0024] In the specific implementation process, such as Figures 1-4 As shown, a quick-freezing device for aquatic products includes an insulated box 1, a container 2, a feeding box 3, and a discharging box 4. The feeding box 3 and the discharging box 4 are connected to the left and right sides of the insulated box 1, respectively, forming a continuous channel for quick-freezing aquatic products.

[0025] The container basket 2 is used to hold aquatic products awaiting quick-freezing. Its bottom has several evenly distributed through holes 13, which allow liquid nitrogen to pass through after vaporization. The width of the inner walls of the insulated box 1, the feeding box 3, and the discharging box 4 is the same as the width of the container basket 2, ensuring that the container basket 2 does not wobble when moving within the boxes, thus guaranteeing the stability of the quick-freezing process.

[0026] The feeding box 3 has a feeding port 14, through which workers can place the container basket 2 containing aquatic products into the feeding box 3. The feeding box 3 is equipped with a pushing assembly, which includes a cylinder 11 and a pusher plate 12. The cylinder 11 is fixedly mounted on the outer side of the feeding box 3, and the pusher plate 12 is fixedly connected to the piston rod of the cylinder 11, slidingly connected to the inner wall of the feeding box 3. During the quick-freezing process, due to the extremely low temperature inside the insulation box 1, the container basket 2 may freeze to the insulation box 1, the feeding box 3, and the discharging box 4, preventing the container basket 2 from moving. The function of the pushing assembly is to push the pusher plate 12 via the cylinder 11 when needed, pushing the container basket 2 from the feeding box 3 into the insulation box 1, ensuring that the container basket 2 can move smoothly.

[0027] An air inlet pipe 9 is connected to the top of the insulated box 1 near the discharge box 4. The air inlet pipe 9 is connected to a liquid nitrogen tank and is used to introduce liquid nitrogen into the insulated box 1. When the liquid nitrogen enters the insulated box 1 from the air inlet pipe 9, it will quickly vaporize and absorb a large amount of heat, causing the temperature inside the insulated box 1 to drop sharply, thereby achieving rapid freezing of aquatic products.

[0028] A first partition 5 is fixedly installed on the top inner side of the insulated box 1, and a second partition 6 is fixedly installed on the bottom inner side. The length of the first partition 5 is greater than the length of the container 2 to prevent liquid nitrogen from flowing directly from the container 2 into the right side of the first partition 5. The height between the bottom of the first partition 5 and the guide roller 7 and the top of the second partition 6 is equal to the height of the container 2, so that the container 2 can pass through the first partition 5 and the second partition 6, while reducing the leakage of vaporized liquid nitrogen from the gaps between the first partition 5, the second partition 6 and the container 2.

[0029] Several evenly distributed guide rollers 7 are rotatably connected inside the insulated box 1. The function of the guide rollers 7 is to reduce the friction of the container 2 during movement, so that the container 2 can move smoothly inside the insulated box 1. Several evenly distributed vent holes 8 are provided on the second partition 6. The vaporized liquid nitrogen can pass through the vent holes 8 and enter the right side of the second partition 6.

[0030] An exhaust pipe 10 is connected to the top of the insulated box 1 near the feed box 3, and the exhaust pipe 10 extends to the outside of the seafood quick-freezing workshop. During the quick-freezing process, liquid nitrogen vaporization will produce a large amount of nitrogen gas. The function of the exhaust pipe 10 is to discharge this nitrogen gas from the workshop to prevent the nitrogen concentration in the workshop from being too high and harming the health of the staff.

[0031] A blower 16 is installed at the bottom of the insulated box 1, near the feed box 3, and is located below the exhaust pipe 10. The function of the blower 16 is to blow outside air into the insulated box 1, reducing the air pressure inside the insulated box 1. This allows the nitrogen gas after liquid nitrogen vaporization to be discharged more quickly through the exhaust pipe 10. At the same time, it can also use low-temperature nitrogen to cool the aquatic products in the holding basket 2 on the right side of the insulated box 1, improving the quick-freezing effect. The bottom of the insulated box 1 is equipped with support legs 17 to support the entire device and make it stable on the ground.

[0032] The discharge box 4 has a discharge port 15. After quick-freezing, the container basket 2 will enter the discharge box 4 from the insulated box 1, and the staff can take out the container basket 2 through the discharge port 15. The height of the inner wall of the feed box 3 and the discharge box 4 is equal to the height of the container basket 2, and the length is greater than the length of the container basket 2. This design can ensure that the container basket 2 can enter and exit smoothly in the feed box 3 and the discharge box 4, and will not get stuck or tilt due to unsuitable height or length. At the same time, it prevents the vaporized nitrogen from overflowing from the container basket 2 and the gap between the feed box 3 and the discharge box 4.

[0033] The working principle of the quick-freezing device for aquatic products provided by this utility model is as follows: First, the worker places the container 2 containing aquatic products into the feeding box 3 through the inlet 14. Then, the pushing component is activated, and the cylinder 11 pushes the push plate 12, pushing the container 2 from the feeding box 3 into the insulation box 1. Under the action of the guide roller 7, the container 2 moves smoothly within the insulation box 1. At this time, liquid nitrogen enters the insulation box 1 through the air inlet pipe 9, rapidly vaporizes, and absorbs heat, quickly freezing the aquatic products in the container 2. Simultaneously, the blower 16 promotes airflow within the insulation box 1, and nitrogen is discharged from the workshop through the exhaust pipe 10. After quick-freezing is completed, the container 2 moves from the insulation box 1 into the discharge box 4, and the worker removes the container 2 through the discharge port 15, completing the entire quick-freezing process for aquatic products.

[0034] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
