Microecological freeze-drying technology, also known as sublimation drying, is a method of freezing a water-containing sample in advance and then sublimating its moisture in a vacuum state. Freeze-dried items, the original biological, chemical and physical properties are basically unchanged, easy to long-term preservation, after adding water can be restored to the state before freeze-drying, and can maintain its original biochemical properties. The sample is pre-frozen in a special bottle and connected to the freeze-drying cover by a rubber valve. The freeze-dried bottle can be replaced at any time through the on-off valve during the freeze-drying process, and different kinds of samples can be freeze-dried at the same time, and 10 special bottles of different capacities can be hung at the same time, and the drying efficiency is high.
