Freeze drying pharmaceuticals uses a process called lyophilization to lower the temperature of the product to below freezing, and then a high-pressure vacuum is applied to extract the water in the form of vapor. The vapor collects on a condenser, turns back to ice and is removed. Finally, a gradual temperature rise extracts all remaining 'bound' moisture from the product. This process retains the physical structure and preserves the material for storage or transport.

With freeze-drying, delicate, unstable or heat-sensitive drugs and biologicals can be dried at low temperatures without damaging their physical structure. Freeze-dried products can be reconstituted quickly and easily, which is particularly valuable in the case of emergency vaccines and antibodies, which need to be administered as quickly as possible.

Applications

  • Pharmaceutical industries
  • Food industry
  • Producing and drying process of nanomaterials
  • Production of porous polymers with Ice Templating method
  • Drying of cryogels
  • Drying of carbon porous structures (carbon nanotubes/ graphene)
  • Drying catalysts include: titanium oxide, vanadium molybdenum oxynitride, alumina nanocrystals
