A fruit and vegetable freeze dryer is a device used to remove moisture from fresh fruits, vegetables, and other foods through freezing and vacuum drying processes. Its working principle is to freeze fresh foods in a low-temperature environment, and then sublimate and dry them under vacuum conditions to remove moisture and achieve dehydration and drying. Specifically, the working process of the fruit and vegetable freeze-drying machine is as follows:
1. Put fresh food into a fruit and vegetable freeze dryer, and then freeze it in a low-temperature environment to form solid ice crystals.
2. During the freezing process, the fruit and vegetable freeze dryer freezes all the moisture in fresh food, forming solid ice crystals.
3. When the temperature of fresh food drops below freezing point, ice crystals begin to sublime, separating water from the fresh food. The water vapor generated by sublimation is extracted by a vacuum pump.
4. After the sublimation is completed, the moisture in the fresh food has been basically removed. At this time, desorption drying can be carried out to further remove the remaining moisture in the fresh food.
5. Finally, the fresh food is cooled to room temperature through air or water cooling, completing the working process of the fruit and vegetable freeze-drying machine.
Working Principle
The working principle of a fruit and vegetable freeze dryer is to use low temperature and vacuum conditions to separate the moisture in fresh food from the food. Through this method, the shelf life and quality of fresh food can be effectively improved.
