Freeze
Freeze-drying or lyophilization is a process for drying heat-sensitive substances such as foods blood plasma and antibiotics The wet substance is frozen and then through sublimation ice (or some other frozen solvent) is removed in the presence of a high vacuum COMSOL Multiphysics
Models heat Freeze Drying
Freeze-drying uses a technique called sublimation where a frozen liquid passes directly from a frozen state and into a gaseous state This ability for a solid to skip the liquid phase and pass directly into the gaseous phase can be explained by a phase diagram where a substance's state under different pressure and temperature conditions is described
