Food dehydrator
Design
Most modern food dehydrators are low-power convection ovens that uses heated air flow to reduce the water content of foods. The water content of food is usually very high, typically 80–95% for various fruits and vegetables and 50–75% for various meats. Removing moisture from food restrains various bacteria from growing and spoiling food. Further, removing moisture from food dramatically reduces the weight and often volume of the food, making it easier for storage. Thus, food dehydrators are used to preserve and extend the shelf life of various foods.
