WHAT IS FREEZE DRYING?
- 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 of biological origin without causing any noticeable change in the original characteristics. Freeze Drying is also the preferred process in the field of Pharmacy, Chemistry and in conservation 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.
HOW FREEZE DRYER WORKS:
- All MAC units are provided with following basic requirements:-
- A Drying Chamber or Manifold on/in which the containers with pre-frozen samples are connected/placed.
- A high Vacuum double stage pumping system with gas ballast with ultimate vacuum of less than 50 microns in the system and 10 microns on pump head to facilitate the vapour flow to the condenser for speedy drying.
- A low temp. condenser to trap the moisture vapour and allow the non-condensable vapours to go to the pump for release to the atmosphere.
