Solids Drying: Basics and Applications

Apr 01, 2014Freeze-drying is an extreme form of vacuum drying in which the water or other solvent is frozen and drying takes place by subliming the solid phase. Freeze-drying is extensively used in two situations: (1) when high rates of decomposition occur during normal drying; and (2) with substances that can be dried at higher temperatures, and that are Get price

Flash freezing

Flash freezing refers to the process whereby objects are frozen in just a few hours by subjecting them to cryogenic temperatures, or through direct contact with liquid nitrogen at −196 C (−320.8 F).. When water is supercooled to temperatures below −48 C (−54 F), it must freeze. Freezing water is a central issue for climate, geology and life. Get price
