Description

Technical Field

[0001] The utility model relates to the technical field of vacuum freezing, in particular to spray impregnation vacuum freeze drying integrated equipment. Background Art

[0002] Freeze dryer is the abbreviation of vacuum freeze dryer. It uses the principle of sublimation to freeze water-containing substances at low temperatures, and directly sublimate the solid ice into gas under a vacuum environment to remove it, obtaining freeze-dried substances with very little water content and rehydration properties. Treatment with freeze dryer equipment can enhance the stability of materials, preserve substances for a long time, and prevent physical, chemical and biological denaturation of dried substances.

[0003] Currently, after vacuum impregnation, the material needs to be continuously transferred between equipment before other processes can be carried out, which is a relatively cumbersome process;

The freeze-drying chamber of this device is equipped with a U-shaped impregnation liquid delivery pipe. The lower end extends from the bottom of the freeze-drying chamber and connects to the impregnation liquid tank. The upper end is connected to a nozzle delivery pipe equipped with an atomizing nozzle, which delivers the impregnation liquid to the atomizing nozzle and sprays it onto the surface of the material. Two refrigeration systems and a raw water collection system are also provided. The atomized spraying of the impregnation liquid after a single vacuum freeze-drying operation avoids nutrient loss, allowing the pre-drying, vacuum impregnation, freezing, and post-drying processes to be completed in a single device, greatly improving the processing efficiency of dried fruits and vegetables.
