A classic application of freeze drying is the production of freeze-dried drugs. Often used for drying dietary supplements.
In particular, the protein-amino acid complex is dried at our freeze drying unit.

After drying - like most of freeze-dried liquid products - easy-to-powder plates.
We are also approached for freeze-drying of inorganic substances.
