APPLICATIONS
Freeze Drying is the process of removing the moisture from a biological
product while maintaining the integrity of the biological products, chemical
structure and activities. Freeze Drying technology is used in particular for
removal of moisture from the products usually biological origin without
causing any noticeable change in the origin without causing any noticeable
change in the original characteristics. Freeze Drying is also the preferred
in the field of Pharmacy, Chemistry and in conversation of food.
ADVANTAGE OF FREEZE DRYING
Heat sensitive biological materials may be freeze-dried without affecting
their potency. The dried materials may be stored for years at room
temperature without loss of their original characteristics.
The freeze-dried material may be transported and shipped in small
containers, and no provision is necessary for refrigeration enroute.
Bacterial growth and enzyme action do not take place in freeze-dried
products and proteins do not coagulate. Oxidation of many materials such as
hemoglobin and vaccines is completely prevented when drying and sealing is
done under high vacuum.
