The Working Principle of a Freeze-Dryer. The core principle of a freeze-dryer is the direct sublimation of water from solid to vapor in a low-temperature vacuum environment, thereby removing moisture from the food. Thus, a freeze-dryer first freezes the food, then extracts the air around it, and gradually raises the temperature in a vacuum environment so that the ice …

How Freeze Dryers Work. Freeze dryers work by first freezing the food to a temperature of around -30°C to -50°C. The frozen food is then placed in a vacuum chamber, where the pressure is reduced to allow the frozen water to sublimate. The water vapor is then removed from the chamber using a condenser or a cold trap, leaving behind a dry ...
