Pharmaceutical Freeze Drying Technology

The removal of ice or other frozen solvents from a substance by sublimation and the removal of bound water molecules by desorption are both examples of pharmaceutical freeze technology. Depending on the industry and area where the drying is taking place, the terms lyophilization and freeze drying are interchangeable. Controlled freeze drying maintains a low enough product temperature throughout the process to prevent changes in the dried product's look and properties.
