Product Description
Working Princple of Freeze Dryer
Under vacuum condition, material is freeze dried via principle of sublimation. The moisture in the pre-frozen material is directly sublimed from solid state (ice) to gaseous state (vapor), without melting. Freeze dried products are formed as sponginess, no shrinkage, rehydration excellent, very little water containing. The freeze dried product in sealed packaging can be stored and transported at room temperature for a long time.
