DE-11: Lesson 35. PRINCIPLE OF FREEZE DRYING

35.3 Principle. Freeze drying also called sublimation drying is the drying of a product in frozen state. The ice evaporates without passing through the liquid state i.e., it sublimes. Conditions of sublimation of pure ice therefore exists below the triple point (0.01 o C and 610.8 Pa) at which all three states of matter can exist.
