How to choose a suitable freeze dryer?
The principle of a freeze dryer is a technical method of preliminarily freezing an aqueous article and then sublimating its water under vacuum to obtain a dried article. The freeze-dried articles are easy to store for a long time, and can be restored to the state before lyophilization and retain the original biochemical characteristics after adding water.

Advantages Of In-situ Freeze Dryers
The in-situ freeze dryer adopts the separate design of the drying chamber and the cold trap, and uses silicone oil as the heat transfer medium, which not only saves energy, but also has a fast production speed (equipped with electric defrosting) and is easy to clean.
