Abstract

Technical Field
[0001] The utility model relates to the technical field of freeze-dried fruit processing, in particular to freeze-dried fruit processing and drying equipment. Background Art
[0002] Freeze-dried fruit uses the vacuum freeze-drying method of a freeze dryer to pre-freeze the moisture in the fruit, and then sublimate the frozen moisture in the fruit in a vacuum environment to obtain freeze-dried fruit. In short, the moisture in the fruit is extracted in a low-temperature environment to retain its original nutrients. Freeze-drying is a drying technology that uses the principle of sublimation. It is a process in which the dried substance is quickly frozen at low temperature, and then in an appropriate vacuum environment, the frozen water molecules are directly sublimated into water vapor and escape.
[0003] During the preparation process of freeze-dried fruits, the fruits need to be placed on trays, and then the trays are placed inside a cold dryer for freeze drying. However, the positions of the trays in the existing cold dryers are fixed, and the spacing between the upper and lower trays cannot be adjusted. This cannot meet the different spacing requirements for different materials, and is inconvenient to use. Utility Model Content
