Freeze Dry Process
Dehydration is an important process for the
preservation and storage of biologicals, pharmaceuticals
and foods. Of the various methods of dehydration,

substances that are heat sensitive. Other than food
processing (e.g., coffee, whole dinners), freeze drying
has been extensively used in the development of
