Food drying equipment for food freeze-drying machine

Food freeze-drying machine is short for food vacuum freeze-drying machine. Food freeze-drying technology originated in the 1930s. At present, food freeze-drying machine has become an important drying equipment for food deep processing.

Freeze-dried food is fast frozen, vacuum ice dehydration, preserving the original color, aroma, taste, nutrition and appearance of the original material, and has good rehydration, and does not contain any additives, can be stored at room temperature for a long time, is an ideal natural health food. Because the finished product is light in weight and easy to carry and transport, freeze-dried food has also begun to enter People's Daily life, becoming a convenient leisure and health food. The demand for freeze-dried food is growing exponentially around the world.

Food freeze-drying machine is composed of freeze-drying warehouse body, refrigeration unit, vacuum unit, circulation unit, electric control unit, etc.

Food freeze-drying machine series is divided into research and development experimental food freeze-drying machine and production food freeze-drying machine, according to the form of heat exchange is divided into contact food freeze-drying machine and radiation food freeze-drying machine.

According to the characteristic requirements of food products and the positioning requirements of lyophilized products, the cryofreezing temperature, primary drying temperature and vacuum degree can be determined, and the lyophilized process data such as drying temperature and vacuum degree and heating rate can be analyzed to ensure that the original nutrients, color, aroma, taste and shape of food remain unchanged after lyophilized treatment, and the moisture content after drying is less than 5%. Can be stored at room temperature for a long time, good rehydration characteristics.
