1. Raw or cooked foods are placed in the freeze dryer where they are frozen to between -30 degrees and -50 degrees Fahrenheit.
  2. Once frozen, the freeze dryer creates a vacuum in the food chamber.
  3. As the food is gradually warmed, the water turns to vapor and evaporates out of the food (sublimation).
  4. When water is added to freeze-dried food, in most case, it regains its original fresh flavor, aroma, texture, and appearance!
