What is a freeze dryer?

A freeze dryer is a machine that uses a process called sublimation to remove water from food. Sublimation is the process of converting a solid directly into a gas, without passing through the liquid phase.

Freeze dryers work by first freezing the food to a very low temperature. The food is then placed in a vacuum chamber, where the pressure is reduced. The low pressure causes the water in the food to sublimate, turning directly from a solid into a gas. The gas is then removed from the chamber, leaving the food dry.

Freeze dryers are used to preserve food for long periods of time. The process of freeze drying removes all of the water from the food, which prevents the growth of bacteria and mold. Freeze-dried food can be stored for up to 25 years without refrigeration.
