Abstract: An electronic dryer for grain or other materials which includes a gas burner and one or more blowers for providing heated air into a plenum chamber from which such heated air passes through the material to be dried between two spaced walls formed with openings such that the heated air can pass therethrough for drying the material. Temperature sensing means in the form of an elongated member such as a wire is mounted within the plenum chamber so as to detect the plenum chamber temperature and to control the duty cycle of the burner and second and third temperature sensing means are mounted between the spaced walls adjacent the inlet and outlet areas of the heated air so as to detect and determine the moisture content in the materials to be dried. These sensors are also elongated and detect the temperature at many portions of the dryer so as to more accurately determine the temperature.
