Freezing stage: Raw product thoroughly freezing, can be done inside a freeze dryer lyophilizer or in external freezer.
Primary drying stage: Frozen product placed in drying chamber, vacuum environment is created and sublimation starts. > 95% physical water was removed.
Secondary drying stage: Higher shelf temp. and extreme vacuum environment is created to remove the bound water. <3% water remaining after drying finish.
