Detailed Embodiment

[0019] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.

[0020] Embodiment 1

[0021] Please refer to Figures 1-4 , a vacuum freeze-drying device for food storage, including a base 1. A plurality of moving wheels 2 are installed on the bottom surface of the base 1, and a cylindrical freezer 3 is arranged on the base 1. A vacuum pumping device 4 is installed on the freezer 3, and a vertically arranged hollow tube 5 is fixedly arranged in the freezer 3. The freezer 3 is divided into a plurality of storage bins from top to bottom by a plurality of grille nets 6. A plurality of accommodation bins are equidistantly arranged in the storage bins through a plurality of partitions 7. A pull-out box 8 adapted to it is movably inserted into the accommodation bin. A sealing gasket is installed on the pull-out box 8, and through holes 9 are opened on the end face of the pull-out box 8 located in the accommodation bin and on the side wall of the hollow tube 5. A cold air pipe 10 is installed in the hollow tube 5. The cold air pipe 10 is connected to a refrigeration device (not shown in the figure) arranged in the base 1, and a plurality of cold air delivery branch pipes 11 adapted to be inserted into the through holes 9 are fixedly arranged on the side wall of the cold air pipe 10. By dividing the freezer 3 into a plurality of storage bins and further dividing the storage bins into a plurality of accommodation bins, when pulling the pull-out box 8 to access food, not only is the loss of cold air in the freezer 3 greatly reduced, the electricity cost is reduced, but also the food in a plurality of pull-out boxes 8 on the same layer does not interfere with each other, avoiding the phenomenon of food deterioration caused by unstable temperature in the freezer 3, improving the insurance effect of the device. And when it is necessary to completely take out the food in the pull-out box 8, the pull-out box 8 can also be completely pulled out, facilitating the taking out of the food.
