What is freeze drying?
Removal of water (and other solvents) from a frozen material by sublimation and
desorption. The process consists of three separate, unique, and interdependent
processes: freezing, primary drying (sublimation), and secondary drying (desorption).

Why freeze dry?
To extend the shelf life of a product.
To stabilize a product, making it easier to transport and less sensitive to temperature.
To produce a product that can be fully reconstituted (IE: for injection).
