The vacuum freezing drying technology, which is also called sublimation drying,
is a technical method that freezes the samples in advance, and then sublimates
its moisture in the vacuum state.

Materials are easier for long term preservation after freezing drying processing.
They can be restored to the original state and maintain its chemical and biological characteristics after being watered. So the freezing drying technology is widely used in medicine, pharmacy, food production, chemistry industry and biological products etc.
