How does a food dehydrator work?
A food dehydrator uses the same two dehydration principles; heat and air. A typical food dehydrator contains an electric component for heat and a fan and air vents for circulation. A food dehydrator’s heating component and fan work in concert to remove moisture from food. As the heat warms the food, its moisture is released and evaporated into the air. To achieve dehydration, that humid, moist air must be removed and replaced with dry air via the food dehydrator’s fan and vents. The faster the air current and the better the ventilation, the faster and better food will be dehydrated.
