The Principle Of Freeze Dryer

Freeze-Drying (hereinafter referred to as freeze-dried) is the water containing substances, first frozen into a solid, and then the water from the solid state sublimation into a gaseous, in order to remove moisture and preserve the material method.

In the compressed air drying process, the freeze-drying is by reducing the compressed air temperature, so that the compressed air in the water precipitation. Freeze dryer (cold dry machine) working principle and refrigerator, compressed air after the compressed air pipe, compressed air temperature to the required temperature, to achieve dry requirements.
