Description

Technical Field

[0001] This utility model relates to the field of bird's nest drying technology, and in particular to a vacuum freeze dryer for pure bird's nest. Background Technology

[0002] Pure bird's nest is a product made by removing impurities and non-edible components from natural bird's nest. This type of bird's nest not only retains its original nutrients, such as protein, amino acids, and various minerals, but also improves its safety and taste. Pure bird's nest is produced using vacuum freeze-drying technology (freeze-drying technology), which freezes bird's nest containing a large amount of water into a solid state under low temperature and low pressure, and then directly sublimates to remove the water, thus obtaining a pure bird's nest product with high rehydration properties, maintaining its original color, flavor, and nutritional components.

[0003] Most pure bird's nest vacuum freeze dryers on the market currently use a single, large-capacity vacuum tank design. While this design can process a large quantity of bird's nest raw materials at once, the large-capacity vacuum tank requires more energy to maintain the necessary low-temperature environment. When performing vacuum freeze drying on small quantities of bird's nest, this is not conducive to rapid cooling and also results in low energy efficiency, which is inconsistent with the development trend of energy conservation and emission reduction. Utility Model Content

[0004] In view of the above-mentioned prior art, the present invention provides a vacuum freeze dryer for pure bird's nest, which can adapt to different production needs and improve energy efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0006] A pure bird's nest vacuum freeze dryer includes a vacuum tank, heat exchange tubes, a vacuum pump, a refrigeration system, and a frame. Multiple vacuum tanks are horizontally fixed on the frame. The heat exchange tubes surround the vacuum tanks and are connected in parallel to the refrigeration system. The vacuum tanks are connected to the vacuum pump through airflow pipes. Both the heat exchange tubes and the airflow pipes are equipped with control valves. A shelf is provided inside the vacuum tank for placing bird's nests.

[0007] Furthermore, the frame includes a support leg, a support platform, and a base, with the support leg located at the bottom of the support platform and the base connected to the lower part of the support leg.

[0008] Furthermore, the refrigeration system includes a compressor, a condenser, and an expansion valve. The heat exchange tube, compressor, condenser, and expansion valve are sequentially connected to form a closed loop. The compressor and condenser are mounted on the base.

[0009] Furthermore, the vacuum pump is mounted on the base.

[0010] Furthermore, the vacuum container includes a container body and a container lid, the bottom of the container lid is rotatably connected to the container body, and the top of the container lid is snapped into the container body by a buckle.

[0011] Furthermore, the can lid is equipped with a valve.

[0012] Furthermore, the shelf includes a lower partition, a first column, a second column, a fixed shaft, and multiple upper partitions. The first column is provided on one side of the lower partition, and the second column is provided on the other side. The fixed shaft is provided on the first column, and each upper partition is provided with a bushing. The bushing is rotatably connected to the fixed shaft.

[0027] Example 1

[0028] Please refer to the attached document. Figures 1-4This application provides a pure bird's nest vacuum freeze dryer, including a vacuum tank 1, heat exchange tubes 2, a vacuum pump 3, a refrigeration system 4, and a frame 5. Multiple vacuum tanks 1 are horizontally fixed on the frame 5. The heat exchange tubes 2 surround the vacuum tanks 1 and are connected in parallel to the refrigeration system 4. The vacuum tanks 1 are connected to the vacuum pump 3 via airflow pipes 6. Both the heat exchange tubes 2 and the airflow pipes are equipped with control valves 7. A shelf 8 is provided inside each vacuum tank 1 for placing bird's nests. The bird's nests are placed on the shelf 8, and then the shelf 8 is pushed into the vacuum tank 1. The heat exchange tubes 2 surround the vacuum tank 1. When the refrigeration system 4 is working, it supplies circulating refrigerant to the heat exchange tubes 2, thereby lowering the temperature inside the vacuum tank 1. Multiple vacuum tanks 1 are installed on the frame 5, each capable of holding bird's nest. Each vacuum tank 1 has a heat exchange tube 2 and a connected airflow pipe equipped with a control valve 7. Opening and closing the control valve 7 controls whether the vacuum tank 1 is evacuated or cooled. Multiple vacuum tanks 1 can be used simultaneously to improve efficiency, or some can be shut down as needed to reduce energy consumption. This invention can adapt to different production demands and improve energy efficiency.

[0029] Specifically, the frame 5 includes support legs 9, a support platform 10, and a base 11. The support platform 10 has the support legs 9 at its bottom, and the base 11 is connected to the lower part of the support legs 9. The support legs 9 are used to fix the support platform 10, and the vacuum tank 1 is installed on the support platform 10. The base 11 is connected to the support legs 9 to improve structural strength. At the same time, the refrigeration system 4 and the vacuum pump 3 can both be installed on the base 11.

[0030] Specifically, the refrigeration system 4 includes a compressor 12, a condenser 13, and an expansion valve 14. The heat exchange tube 2, compressor 12, condenser 13, and expansion valve 14 are sequentially connected to form a closed loop. The compressor 12 and condenser 13 are mounted on the base 11. Mounting the compressor 12 and condenser 13 on the base 11 facilitates the arrangement and installation of equipment components. When the compressor 12 is working, it compresses the refrigerant, which is then cooled by the condenser 13. Finally, the refrigerant enters the heat exchange tube 2 through the expansion valve 14 to evaporate and absorb heat, thereby reducing the temperature inside the vacuum tank 1.

[0031] Specifically, the vacuum pump 3 is mounted on the base 11, which facilitates the installation of the vacuum pump 3.

[0032] Specifically, the vacuum container 1 includes a container body 15 and a lid 16. The bottom of the lid 16 is rotatably connected to the container body 15, and the top of the lid 16 is snapped into the container body 15 by a buckle 17. The lid 16 can be flipped downwards to open the container body 15, after which the container body 15 is placed on the shelf 8. Finally, the lid 16 is closed and secured firmly using the buckle 17.

[0033] Specifically, the can lid 16 is equipped with a valve 18. Before opening the can lid 16, the valve 18 is opened to allow air to slowly enter the can body 15, reducing the pressure difference between the inside and outside, and making it easier to open the can lid 16.

[0034] Example 2

[0035] Please refer to the attached document. Figures 5-6 The difference between this embodiment and Embodiment 1 is that the shelf 8 includes a lower partition 19, a first column 20, a second column 21, a fixed shaft 22, and multiple upper partitions 23. The lower partition 19 has the first column 20 on one side and the second column 21 on the other side. The first column 20 has the fixed shaft 22. Each upper partition 23 has a bushing 24, which is rotatably connected to the fixed shaft 22. The upper partitions 23 can rotate relative to the fixed shaft 22. When placing bird's nest, the upper partitions 23 of the shelf 8 are first rotated upwards to expose the lower partition 19, preventing obstruction of operation when placing bird's nest on the lower partition 19. After the bird's nest is placed on the lower partition 19, the upper partitions 23 are flipped back to their original position, and the upper partitions 23 are rotated and mounted on the two columns, maintaining the stability of the upper partitions 23.

[0036] Specifically, it also includes a handle 25, which is located at the rear end of the shelf 8. One end of the handle 25 is connected to the first upright 20, and the other end is connected to the second upright 21. The operator can easily push the shelf 8 into the vacuum tank 1 by holding the handle 25.

[0037] Specifically, the front end of the shelf 8 is provided with a limiting plate 26, which is connected to the lower partition. After the shelf 8 is pushed into the vacuum tank 1, the limiting plate 26 acts as a limit, allowing the first and second partitions to be positioned in the middle of the vacuum tank 1.

[0038] When placing bird's nests on the shelf 8, the lower layer of bird's nests can be arranged neatly before placing the upper layer. In another embodiment, bird's nests can be placed on the lower and upper partitions at the front of the shelf 8 first, then the shelf 8 can be pushed into the vacuum chamber 1 a certain distance before placing the bird's nests on the lower and upper partitions. This can reduce the possibility of bird's nests being placed beyond the shelf 8 and blocked by the side wall of the vacuum chamber 1 due to misoperation. The specific operation is as follows: first, put the front of the shelf 8 into the vacuum chamber 1, then flip the upper partition 23 at the front, place bird's nests on the lower partition 19 below the upper partition 23, then reset the upper partition 23, and then place bird's nests on the upper partition 23 again, then push the upper partition 23 into the vacuum chamber 1, and then flip the upper partition 23 adjacent to the upper partition 23, and continue to place bird's nests in the same manner.

[0039] Specifically, both the upper and lower partitions are provided with a number of through holes 27. The through holes 27 can improve air permeability and facilitate the discharge of gas from the vacuum tank 1.

[0040] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
