Freeze drying process, also known as lyophilization or sublimation, consists of two main stages. Initially fresh cut products are transported in to so called "Blast Freezer" and frozen below -40C temperature. Once products are deeply frozen, they are put into freeze drying chamber where vacuum is created by lowering the air pressure at certain degree.

Afterwards low temperature heat is transferred to products through the shelves of the freeze-drying chamber and ice in the product becomes gas bypassing liquid phase. The whole process may last from 24 hours up to 40 hours depending on the type, size and amount of the product. Almost 97-98% of water will be sublimated from products during freeze-drying process.
