Freeze drying, also known as lyophilisation or cryodesiccation, is a low temperature dehydration process that involves freezing the product, lowering pressure, then removing the ice by sublimation. This is in contrast to dehydration by most conventional methods that evaporate water using heat. Freeze drying results in a high quality product because of the low temperature used in processing.

During primary drying, you want to set the shelf temperature to just below the sample's eutectic temperature. With a water sample, this would mean the shelves would be set at about -5˚C since water freezes at 0˚C. Allow just enough heat to the shelves to encourage the molecules of the sample to move, yet prevent melting.

Jul 15, 2019 · Lyophilization, also known as freeze-drying, is a process used for preserving biological material by removing the water from the sample, which involves first freezing the sample and then drying it, under a vacuum, at very low temperatures. Lyophilized samples may be stored much longer than untreated samples.
