Description

Technical Field

[0001] This utility model relates to the field of tremella processing technology, specifically a low-temperature vacuum preservation device for tremella processing. Background Technology

[0002] Fresh white fungus contains a lot of water and is very susceptible to bacterial contamination and spoilage. For these reasons, fresh white fungus has a short shelf life and therefore needs to be preserved using a freshness-locking device.

[0003] As disclosed in the patent announcement CN218999426U, a low-temperature vacuum preservation device for processing fresh tremella includes a refrigeration subsystem and a preservation subsystem. Both subsystems are communicatively connected to a microcontroller. The refrigeration subsystem cools the preservation chamber, while the preservation subsystem preserves the fresh tremella. The beneficial effects of this invention are: the vacuum pump extracts air from the preservation chamber, reducing the oxygen content and thus extending the preservation time, improving the preservation effect, and reducing spoilage.

[0004] While the aforementioned patents enable fresh white fungus to be preserved for a longer time and with better preservation effects, the temperature inside the preservation chamber may be uneven during the rapid cooling process. Especially when the fresh white fungus is stacked densely, the temperature in some areas may not be able to drop to -18℃ quickly. Uneven temperature may cause some fresh white fungus to fail to achieve the ideal preservation effect, thus affecting the overall preservation quality. Utility Model Content

[0027] like Figure 1-5 As shown, this utility model provides a technical solution:

[0028] A low-temperature vacuum preservation device for processing silver ear fungus includes a preservation box 1. Several trays 2 are movably installed in the middle of the inner side of the preservation box 1. A rotating mechanism is provided between the preservation box 1 and the trays 2. The rotating mechanism includes a rotating rod 7. The rotating rod 7 is movably installed in the middle of the inner side of the preservation box 1. The middle part of the trays 2 is fixedly connected to the wall of the rotating rod 7. A motor 8 is fixedly installed at the top of the middle part of the preservation box 1. The output shaft of the motor 8 is fixedly connected to the rotating rod 7. A refrigeration box 4 is fixedly installed at the bottom of the preservation box 1. A cooling mechanism is provided between the preservation box 1 and the refrigeration box 4. The cooling mechanism includes wall grooves 9. Wall grooves 9 are opened on both sides inside the preservation box 1. An evaporator 10 and an evaporator 2 11 are fixedly installed inside the wall grooves 9 on the two sides, respectively. A compressor 12 is fixedly installed on the left side inside the refrigeration box 4. A condenser 13 is fixedly installed on the right side of the interior of the cold box 4. A fan assembly 14 is fixedly installed on the upper right side of the interior of the cold box 4. The two ends of the compressor 12 are connected to the evaporator 11 and the condenser 13 respectively. The other end of the condenser 13 is connected to the evaporator 10. The other end of the evaporator 10 is connected to the evaporator 11. A vacuum mechanism is provided on the upper back of the fresh food box 1. The vacuum mechanism includes a bracket 5. The bracket 5 is fixedly installed at the top of the middle of the back of the fresh food box 1. A vacuum pump 6 is fixedly installed at the top of the bracket 5. The suction end of the vacuum pump 6 is connected to the interior of the fresh food box 1. A door 20 is movably installed on the front of the fresh food box 1. A vacuum sensor 21, a temperature and humidity sensor 22, and a controller 23 are fixedly installed from top to bottom on the outside of the right side of the fresh food box 1.

[0029] In this embodiment, evaporators 10 and 11 are installed on both sides of the inside of the preservation box 1, respectively. Combined with the uniform rotation of the rotating tray 2, the fresh white fungus is evenly exposed to the cooling range of the evaporators during the cooling process, ensuring that each part of the fresh white fungus can be quickly cooled to below -18°C, avoiding the problem of uneven temperature caused by single-point cooling or dense stacking in the prior art.

[0030] like Figure 3 and Figure 5 As shown, several fan-shaped storage boxes 3 are movably installed on the tray 2. A fixing mechanism is provided between the bottom of the tray 2 and the fan-shaped storage boxes 3. The fixing mechanism includes a fan-shaped groove 15. Several fan-shaped grooves 15 are opened with equal arc on the upper surface of the tray 2. The fan-shaped storage boxes 3 match the fan-shaped grooves 15. A positioning groove 16 is opened in the middle of the front of the tray 2 and the fan-shaped groove 15. A fixing block 17 matching the positioning groove 16 is fixedly installed below the middle of the fan-shaped storage box 3. A locking button 18 is movably installed in the middle of the fixing block 17. A threaded hole 19 is opened in the middle of the inner side of the positioning groove 16.

[0031] In this embodiment, the fan-shaped storage box 3 and the tray 2 are matched and installed through the fan-shaped groove 15 and the fixing block 17, and are fixed by the thread of the locking button 18. The operation is simple and stable, which facilitates the quick filling and taking out of fresh white fungus, while avoiding the displacement or scattering of fresh white fungus during rotation.

[0032] Working Principle: During operation, freshly picked white fungus is first evenly placed in the fan-shaped storage box 3 on tray 2. The fan-shaped storage box 3 is securely connected to tray 2 via a fixing mechanism, ensuring that the fresh white fungus will not shift or scatter during subsequent rotation. Then, the door 20 of the preservation box 1 is closed, and the controller 23 is activated, starting the device. The controller 23 first starts the motor 8, which drives the rotating rod 7 to rotate. The rotating rod 7 is fixedly connected to tray 2, so tray 2 and the fan-shaped storage box 3 on it begin to rotate at a uniform speed. The introduction of the rotating mechanism ensures that the fresh white fungus is evenly distributed within the preservation box 1. Simultaneously, the controller 23 activates the cooling mechanism in the refrigeration box 4, and the compressor 12 begins to work, compressing the refrigerant and delivering it to the condenser 13. With the assistance of the fan assembly 14, the condenser 13 cools the refrigerant into a liquid state. The liquid refrigerant then flows sequentially through evaporator 10 and evaporator 21. Evaporators 10 and 11 are installed in the wall grooves 9 on both sides of the inside of the preservation box 1, respectively, to rapidly cool the interior of the preservation box 1 through evaporative heat absorption. During the cooling process, the rotating tray 2 ensures that the fresh white fungus is evenly exposed to the cooling range of evaporators 10 and 11, ensuring that each portion of the fresh white fungus is rapidly and evenly cooled to below -18°C. At the same time, the controller 23 activates the vacuum mechanism, and the vacuum pump 6 starts working to extract the air from the preservation box 1, significantly reducing the oxygen content and placing the fresh white fungus in a vacuum environment, further extending its shelf life.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
