Industrial Fruit and Vegetable Vacuum Freeze Dryer for Food Processing Industry

Product Introduction
The vacuum freeze-drying machine uses vacuum freeze-drying technology to directly sublime the moisture in the material into water vapor in an ice state, thereby removing the moisture and achieving the purpose of drying. This method not only preserves the original structure and nutritional components of the material, but also extends its shelf life and maintains its original taste, color, and flavor.

Working principle
The basic principle of vacuum freeze-drying machine is based on the three state changes of water. Water can exist in solid, liquid, and gas states, which can both be converted and coexist with each other. Under high vacuum conditions, utilizing the principle of sublimation, the moisture in pre-frozen materials is directly removed as water vapor through ice sublimation without melting, thus achieving the purpose of freeze-drying. Freeze dried products have a sponge like appearance, no drying shrinkage, excellent rehydration properties, and minimal moisture content. After packaging, they can be stored and transported at room temperature for a long time.

Application area
Vacuum freeze-drying machines are widely used in multiple fields, including:

1. Medicine: Used to preserve bioactive substances such as serum, bacterial strains, traditional Chinese and Western medicine, etc. Due to its highly sensitive thermal instability, biological agents often require freeze-drying technology to ensure their activity and stability.
2. Biological products, such as virus vaccines, proteins, peptides, and nucleic acids, can effectively maintain their activity and stability through freeze-drying technology.
3. Food: Used for drying dehydrated vegetables, fruits, and other foods to maintain their original structure and nutritional content, and extend their shelf life.
4. Chemical industry: used to process certain chemical raw materials and intermediates to maintain their purity and stability.

1. Refrigeration system: used to cool materials to a frozen state.
2. Vacuum system: Create a high vacuum environment to promote water sublimation.
3. Thermal oil heating system: provides necessary heat to help the moisture in the material sublime.
4. Moisture removal system: Remove water vapor generated by sublimation and maintain a vacuum state.
