We at Frozen in Time often hear the question, "What is freeze drying exactly?"  
In short, freeze drying is a process that removes water from a frozen material via sublimation - the direct conversion of ice to vapour. 
The aim of freeze drying is to obtain a readily water-soluble product which has the same characteristics as the original product after the readdition of water. 
Freeze drying is often considered the "Gold Standard" of dehydration and drying processes in terms of overall quality.
