Abstract
The machine is operable for continuously extracting moisture or dehydrating food. A plurality of food tray are insertable into a main chamber having an air diffuser mounted on one side and an air collector on the opposite side. Air is drawn through the chamber by a blower. Heat is applied to the food by heater element incorporated at the underside of the food trays. Dampers are located at the air inlet and air exhaust ducts, which may be monitored and adjusted by temperature and moisture sensors for maintaining a selected temperature and moisture condition to extract the moisture content of the food to a desirable condition. The processed food may be retrieved from the machine while a new tray of food is being placed into the chamber.
