Freeze drying is based on the physical process of sublimation: in a vacuum, water changes from its solid, frozen state directly into vapour – the ice evaporates. The product to be dried is first deep frozen at normal pressure, usually by cryogenic liquefied gases. It is then placed under vacuum, so the frozen moisture within the product sublimates and is removed as vapour.
