Freeze dryer is widely used in medicine, pharmacy, biology research, chemical industry and food production ,etc. After the freeze drying process,a long term preservation for products is much easier. They can be restored to the original state and maintain their chemical and biological characteristics after being watered.
The vacuum freezing drying techinology, 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.
