Freeze Drying - an overview | ScienceDirect Topics

Freeze Drying - an overview | ScienceDirect Topics

Freeze drying is a drying process in which the solvent and/or suspension medium is crystallized at low temperatures and thereafter sublimed from the solid state directly into the vapor phase. The main goal of freeze drying is to produce a substance with good shelf stability that is unchanged after reconstitution with water, although this also depends very much on the last step of the …
