The drying process is a critical final stage in various manufacturing processes – it influences the quality of many a product and has many industrial applications, particularly in the food and pharmaceutical sectors. Freeze drying (lyophilization) is a drying method where the solvent is frozen prior to drying and is then sublimed. In addition to providing an extended shelf-life, successful freeze-drying should yield a product that has a short reconstitution time with acceptable potency levels. The process should be reproducible with well defined temperature, pH and time parameters for each step. Visual and functional characteristics of the dried product are also important for many applications.
