Vacuum freeze-drying technique, referred to as freeze-drying, also known as sublimation drying. Aquifer material is pre-frozen and then in a vacuum sublimation method. The freeze-dried items, the original biological, chemical characteristics of the same, easy-to long-term preservation and water after freeze-drying can be restored to the state before, and maintains the biochemical characteristics of the original. Therefore, the freeze-drying in the chemical industry, biological products, chemicals and food industry, vaccines, blood products and other areas of freeze-drying technology is applied.
