Pharmaceutical Freeze Drying
Freeze drying have been standard process in pharmaceutical and biotechnology industries, it could success and no damage turn them to stable/long shelf life/easy storage/easy transport solid phase, by add solvent or water, could quick rehydration.
Pharmaceutical Freeze Drying Process:
Freeze drying also known as lyophilization or sublimation, is a low temperature drying process that skip liquid phase. Freeze drying works by freezing pharmaceutical to solid, and then reduce its surround pressure(drying house), which result the solid water (ice) will direct vapor to gas phase. By this way, water in raw material success move out.
Pharmaceutical Freeze Dryer Selection:
Mainly, there are 2 types pharmaceutical freeze drying machine: bulk loading and stoppering loading.
- Bulk loading models are widely use in pharmaceutical, biological, chemical, blood, enzymes, drying on trays/shelves.
- Stoppering models have more functions, except bulk loading, raw material also could drying and sealing in vials or bottles under vacuum.
Pharmaceutical Freeze Drying Cycle Time:
Depends on loading volume and raw material features, pharmacy freeze drying may take several hours to several days, the drying time also influence a lot by freeze drying recipe.
Applications In Pharmaceutical Freeze Drying:
- Bio samples
