Vacuum freeze drying industry has made rapid development in recent years. Vacuum freeze drying equipment is used in the field of biological pharmacy. In the pharmaceutical industry, a large number of vacuum freeze drying to produce vaccines, antibiotics, etc. Get a large number of applications in the field of health care products, such as dried cordyceps, freeze dried sea cucumber, antler, lyophilized dendrobium etc.

    At present, our country's vacuum freeze drying equipment industry has begun to enter the mature stage of development, has been able to better satisfied the actual needs of users in various fields, and in the price only half of the same products abroad. This makes the domestic equipment has obvious advantages in the market competition. Any process may become the "bottleneck" of the vacuum freeze drying process. It depends on the design, operation conditions and characteristics of the dry material. Only by improving the efficiency of heat transfer and mass transfer, increasing the surface area of the material, can we achieve faster drying rate.

    At present, the vacuum freeze drying equipment industry in China has begun to enter a relatively mature stage of development, although there is still a gap compared with the developed countries. But in general, the production of vacuum freeze drying equipment is very impressive.
