DETAILED DESCRIPTION

[0020] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0021] Example: See Figure 1-3 A vacuum pre-cooling and fresh-keeping device comprises a bottom plate 1, a water tank 2 and a fresh-keeping box 3, wherein the water tank 2 is fixedly mounted on the upper end of the bottom plate 1, the fresh-keeping box 3 is fixedly mounted on the upper end of the water tank 2 and is connected to the water tank 2, a vacuum pre-cooling structure is connected to the outside of the fresh-keeping box 3, and a sliding installation structure is arranged inside the fresh-keeping box 3;

[0022] The vacuum precooling structure includes: a vacuum tube 4, a one-way valve 5, a vacuum pump 6, an air intake pipe 7, an air intake valve 8, and an air intake filter assembly;

[0023] One end of the vacuum tube 4 is connected to the center of the top of the fresh-keeping box 3, the one-way valve 5 is fixedly installed on the upper end of the vacuum tube 4, the vacuum pump 6 is fixedly installed on one side of the upper end of the bottom plate 1, and the air inlet end is connected to the other end of the one-way valve 5, one end of the air inlet pipe 7 is connected to one side of the upper end of the fresh-keeping box 3, the air inlet valve 8 is fixedly installed on the upper end of the air inlet pipe 7, and the air inlet filter assembly is installed on the lower end of the air inlet pipe 7.

[0024] During use, the staff first places the food that needs to be pre-cooled and preserved on the upper end of the sliding installation structure, then embeds the sliding installation structure into the fresh-keeping box 3, and closes the fresh-keeping box 3. Then, by driving the vacuum pump 6 on one side of the upper end of the bottom plate 1 to work, the gas in the fresh-keeping box 3 is extracted through the vacuum tube 4, so that a negative pressure state is formed in the fresh-keeping box 3. Under the vacuum environment, the collision of gas molecules is reduced, and the interaction force between molecules is reduced, thereby reducing the boiling point and freezing point of the substance, and the free water on the surface of the cooled object is vaporized, taking away its own and environmental heat, thereby achieving a cooling and temperature reduction effect. Vacuum pre-cooling is to use vacuum conditions to make Water evaporates rapidly at a relatively low temperature in the vacuum treatment chamber. In this process, a large amount of heat is consumed. In the absence of an external heat source, a cooling effect is generated in the vacuum chamber. The one-way valve 5 is provided to ensure the air intake sealing state of the vacuum tube 4. During the pre-cooling process, the generated water droplets are collected through the sliding mounting assembly in cooperation with the water tank 2 to facilitate subsequent water recycling. When the pre-cooling is completed, the air intake valve 8 at the upper end of the air intake pipe 7 is opened, and the gas is filtered through the air intake filter assembly and then introduced into the fresh-keeping box 3 through the air intake pipe 7, so that the air pressure in the fresh-keeping box 3 is consistent with that of the outside world. The food is then taken out to facilitate the re-putting of the food.

[0025] In the specific implementation process, the sliding installation structure includes: two first water guide plates 9, two installation platforms 10, an installation frame 11 and a moving wheel set 12;

[0027] When placing the food, the staff will place the food on the upper end of the installation frame 11. The installation frame 11 can be used to separate and store the food. Then, the installation frame 11 is moved into the fresh-keeping box 3 through the movable wheel group 12. The movable wheel group 12 is supported by the installation platform 10 at the upper end of the first water guide plate 9 to ensure the installation stability of the installation frame 11. The dripping water droplets are guided by the two first water guide plates 9 to flow into the water tank 2 at the lower end of the fresh-keeping box 3, and finally the water can be discharged through the drainage sealing valve 17.

[0030] When air is taken into the fresh-keeping box 3, the air is filtered through the two filter frames 15 and the filter cavity 16 in the filter tube 14, and then the gas is transported to the air intake pipe 7 through the connecting flange 13. The two filter frames 15 and the filter cavity 16 can fully filter the gas and effectively prevent foreign matter from entering the box. During subsequent maintenance and replacement, the filter tube 14 can be quickly replaced through the set connecting flange 13 to ensure the overall efficiency of maintenance.
