Technical Field

[0001] This utility model relates to the field of lactic acid bacteria storage technology, specifically a low-temperature storage device for fermented milk production. Background Technology

[0002] Fermented lactic acid bacteria milk is a widely used dairy product. In modern society, people are paying more and more attention to health. Scientific discoveries have shown that lactic acid bacteria are an essential flora for the human body, closely related to health and longevity, and have certain anti-tumor effects. Therefore, more and more people are drinking fermented lactic acid bacteria milk. However, fermented lactic acid bacteria milk is a dairy product that is highly susceptible to contamination by bacteria in the air, which can cause it to spoil and affect its consumption. Therefore, it is necessary to use low-temperature storage devices for fermented lactic acid bacteria milk.

[0003] Most existing storage devices do not allow for easy disassembly of the storage container, making it difficult to clean the inside of the container and resulting in poor performance.

[0004] To address the aforementioned issues, a low-temperature preservation device for fermented milk production is proposed. Utility Model Content

[0028] Reference Figure 1-3 This utility model discloses a low-temperature preservation device for fermented milk production, comprising a low-temperature cylinder 1, within which a low-temperature chamber 2 is provided. The thickness between the low-temperature chamber 2 and the placement slot 11 is relatively thin to avoid affecting the cooling effect on the storage container 12. The placement slot 11 is located at the top of the low-temperature cylinder 1 for placing the storage container 12. A cooling pipe 3 with a spiral structure is fixedly connected inside the low-temperature chamber 2. The output end of a cooler 24 extends into the low-temperature chamber, working in conjunction with the cooling water circulation to achieve a low-temperature environment. A water tank 4 is located on the right side of the low-temperature cylinder 1, with a water pump 5 fixedly connected to its top. Both ends of the water pump 5 are fixedly connected to connecting pipes 6, with the top of the pump being the outlet and the right side being the inlet. A cooler 9 is connected through and fixedly connected to the upper front end of the low-temperature cylinder 1, with its output end extending into the low-temperature chamber 2. A temperature sensor 10 is fixedly connected to the inner wall of the low-temperature chamber 2, enabling the detection of the temperature within the chamber. A storage container 12, made of stainless steel, is installed inside the placement slot 11. Handles 14 are fixedly connected to both sides of the storage container 12, allowing for easy removal. Insertion holes 15 are provided on both sides of the handles 14, serving as limiters.

Limiting components are installed through the limiting blocks 16, and a controller 24 is fixedly connected to the lower front end of the cryogenic cylinder 1.

[0029] Reference Figure 3 The limiting component includes a fixed cylinder 17, which is connected to and fixedly connected to the limiting block 16. A telescopic groove 18 is provided on the inner side of the fixed cylinder 17. A pull rod 19 is connected through and slidably in the telescopic groove 18. A plug 20 is fixedly connected to one end of the pull rod 19. An actuating element 21 is provided on the outer side of the fixed cylinder 17.

The plug 20 is located in the telescopic groove 18 and corresponds to the insertion hole 15. A spring 23 is sleeved on the outer ring of the pull rod 19 and is located in the telescopic groove 18. The limiting component can control the extension and retraction of the plug 20 in the telescopic groove 18. By controlling the plug 20 to extend and insert into the insertion holes 15 on both sides of the handle 14, the handle 14 is limited, thereby realizing the quick limiting and disassembly of the storage bucket 12. The limiting component drives the insertion post 20 to extend and retract via a lever, which cooperates with the insertion hole 15 of the handle 14 to enable quick assembly and disassembly of the storage container 12. The insertion post 20 of the limiting component is adapted to the insertion hole 15 of the handle 14, and the spring 23 is sleeved on the outer ring of the pull rod 19 to realize the automatic reset and limiting of the insertion post 20.

[0030] Reference Figure 1-3 The upper connecting pipe 6 passes through the low-temperature cylinder 1 and is fixedly connected to the upper end of the cooling pipe 3. The upper connecting pipe 6 is also connected to the outlet of the water pump 5. The lower connecting pipe 6 passes through and is fixedly connected to the water tank 4. The lower connecting pipe 6 is also connected to the inlet of the water pump 5. A return pipe 7 passes through and is fixedly connected to the left side of the water tank 4. The end of the return pipe 7 passes through the low-temperature cylinder 1 and is fixedly connected to the lower end of the cooling pipe 3. The return pipe 7 facilitates the return of water from the cooling pipe 3 to the water tank 4. A top cover 13 is provided on the top of the storage container 12. The top cover 13 is threadedly connected to the top of the storage container 12. The top cover 13 serves to seal the storage container 12. Inlet and outlet water pipes 8 are fixedly connected to the upper and lower front ends of the water tank 4.

[0031] Working Principle: During operation, after the controller 24 is activated, the cooler 9 at the front end of the low-temperature chamber 1 begins to work, directly releasing cooling energy into the low-temperature cavity 2 to rapidly lower the air temperature inside the cavity, initially establishing a low-temperature environment suitable for fermented milk storage (typically 2-8℃). The water pump 5 starts simultaneously, drawing cooling water from the water tank 4 through the connecting pipe 6. The cooling water is then transported through the upper connecting pipe 6 to the cooling pipe 3 inside the low-temperature cavity 2. As the water flows through the cooling pipe 3, it absorbs heat from the low-temperature cavity 2, further assisting in maintaining the low temperature inside the cavity. The cooled water, having absorbed heat, flows back to the water tank 4 through the return pipe 7, forming a closed-loop water circulation, continuously controlling the temperature of the low-temperature cavity 2. If the water temperature in the water tank 4 is too high, the cooling water can be replaced through the inlet and outlet water pipes 8 at the front end to ensure the circulating cooling effect. The temperature sensor 10 on the inner wall of the low-temperature cavity 2 continuously monitors the temperature inside the cavity and transmits the temperature data to the controller 24 in real time. When the controller 24 detects that the temperature is higher than the set value, it automatically increases the cooling power of the cooler 9 and accelerates the water circulation speed of the water pump 5 to enhance the cooling effect. When the temperature is lower than the set value, the controller 24 will reduce the power of the cooler 9 and slow down the water circulation speed to prevent the fermented milk from freezing or being damaged due to excessively low temperature. When it is necessary to remove the storage container 12, the levers 21 on both sides of the handle 14 are pulled outwards. After the levers 21 rotate 90°, their bottoms are perpendicular to the outside of the fixed cylinder 17, limiting their position. At this time, the levers 21 generate a lever force with the pivot 22 as the fulcrum, causing the pull rod 19 to slide outwards along the telescopic groove 18. This allows the pull rod 19 to be pulled, which in turn causes the insertion post 20 to compress the spring 23 and retract back into the telescopic groove 18. At this point, the insertion post 20 disengages from the insertion hole 15, releasing the lock on the handle 14. The storage container 12 can then be removed for cleaning via the handle 14. During installation, place the storage container 12 into the placement slot 11, and align the handle 14 between the two limit blocks 16. After placement, pull the lever 21 on both sides of the handle 14 inward. At this time, the spring 23 resets and drives the insertion post 20 to extend out of the telescopic slot 18 and insert into the insertion hole 15 on both sides of the handle 14, thereby locking the storage container 12 and ensuring the stability of the storage container 12.
