Freeze-drying is a dehydration process typically used to preserve a perishable material or make the material more convenient for transport. Freeze-drying works by freezing the material and then reducing the surrounding pressure to allow the frozen water in the material to sublimate directly from the solid phase to the gas phase.

The VirTis Freezemobile 3.3 is a mechanically refrigerated freeze dryer that takes a product from a frozen to a dried state while under vacuum, effectively removing up to 99% of the moisture.
