Freeze Drying and the Need to Measure Humidity Freeze Drying in General. The freeze drying method can be traced back to prehistoric times and was used by the Incas who stored their crops on the mountain heights above Machu Picchu: the cold mountain temperatures froze the food and the water inside slowly vaporized under the low air pressure of the high altitudes.

Principles of Freeze Drying The freeze drying process consists of three stages: prefreezing, primary drying, and secondary drying. Prefreezing: Since freeze drying is a change in state from the solid phase to the gaseous phase, material to be freeze dried must first be adequately prefrozen. The method of prefreezing and the final temperature of the

Freeze drying, also known as lyophilization or cryodesicion, 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. Because of the low temperature used in processing, the quality of the rehydrated …
The process of freeze-drying relies on the vapor pressure of ice. Even at temperatures as low as –50°C, the ice sublimes and leaves a very porous, low-density cake containing the stabilized drug. Since the sublimation rate (drying rate) is very temperature-dependent, approximately double for a 5°C increase 5
