Air is removed from the chamber, creating a vacuum. Under low-pressure conditions, the ice in the food, when heated during the dry process, changes directly into water vapor without melting. This step is called sublimation.

Drying & Water Capture
The water vapor that comes out of the food collects as ice on the inside walls of the chamber.

Final Drying
Gentle heat removes any remaining moisture from the food, ensuring long-term stability.
