Vacuum freeze-drying technology is a new technology to freeze water containing materials at low temperature, and then to sublime ice into steam and side by side under vacuum. It is a multidisciplinary integrated application technology which is rapidly developed with the development of refrigeration, vacuum, biology, electronics and other technologies.

The application of vacuum freeze-drying technology is very extensive. Almost all agricultural and sideline products, such as meat, poultry, eggs, aquatic products, vegetables, fruits and so on, can be made into freeze-dried foods, condiments, instant foods and so on.

Vacuum freeze-drying technology is widely used in the food industry, such as the following products. The process is usually pretreated including, picking, peeling, cleaning and slicing, quick freezing, freeze-drying, weighing and packing. Some freeze-dried foods are used to make fast referenced powder.

The advantages of freeze-dried food:

1) at low temperature freeze drying, especially suitable for heat sensitive food, so as not to denaturation or inactivation. Special flavor foods have little loss of flavor substances and can preserve the color and fragrance of food to the maximum extent.

2) freeze drying does not change the physical structure of the food, and the chemical changes are very small. After drying, it is porous and porous, and the volume is almost invariable.

3) quick rehydration, easy to eat. After drying, the porous material is porous and spongy, and the water is dissolved quickly and completely, almost immediately to restore the original shape.

4) the vacuum degree of the drying process is high, and the oxidizing material is protected.

5) the weight of freeze-dried food is light and small, and it is easy to store and transport. After packing all kinds of freeze-dried vegetables, the volume reduced dozens of times, the weight reduced more than ten times, and the storage and transportation cost of packing was greatly reduced.
