Products Description

Working Principle of lyophilization and freeze drying

Instead of the traditional method of vaporization and dehydration, vacuum freeze drying technology directly sublimates ice into water vapor to dehydrate the product.

In the process of freeze drying, the material will be frozen to -40~-50 ℃ first, then the frozen material will be put into the vacuum drying tank for dehydration, and the automatic control system will automatically run the food freeze dryer according to the set vacuum degree and heating temperature to ensure the freeze drying effect of the material.

During the drying process, the water vapor sublimated by the material will be condensed on the surface of the cold trap coil of the food freeze dryer. After the freeze drying is finished, press the frost button of the freeze dryer, the system will automate the frost and discharge the water and ice on the cold trap coil, so as to prepare for the next freeze drying; the frosting time only takes 15 minutes.

Advantages of vacuum freeze dryer
Compared with the traditional hot air dehydration products, freeze drying technology can keep the food, the material will not shrink or darken after drying.

In addition, freeze drying technology is low temperature drying technology, the nutrients of food are preserved to the maximum extent. The rehydration rate is extremely high because the sublimation process causes minimal damage to the material structure and cellular organization.

After hydration, the product is very close to the characteristics of the fresh material. Due to the low moisture content after freeze-drying, freeze-drying is easier to transport and store in a more cost-effective manner than frozen products.

Freeze-dried foods can be stored for at least 5 years.
