Pharmaceutical freeze dryer
harmaceutical freeze dryer is suitable for drying heat sensitive raw materials that can decompose or polymerize or deteriorate at high temperature. It is widely used in pharmaceutical, chemical, foodstuff. Under the condition of frozen and vacuum, the boiling point of raw material will decrease and make the evaporation efficiency higher. Therefore for a certain amount of heat transfer, the conducting area of dryer can be saved.
Features of pharmaceutical freeze dryer:
The heat source for evaporation may be low pressure steam or surplus heat steam.
The heat loss is less.
Before freeze-drying, the treatment of disinfection may be carried out. During the period of drying, there is no impurity material mixed. It is in conformity with the requirement of GMP.
It belongs to static dryer. So the shape of raw material to be dried should not be destroyed.
Easy maintenance and high reliability.
