<p>An electronic controller (10) for a rotary cooking machine of the type having a cooking vessel rotatable about its longitudinal axis, a drive motor (34) for rotating the cooking vessel, a heating element (32) disposed adjacent the cooking vessel for heating the contents thereof, and a temperature probe (24) for providing a temperature signal indicative of the temperature of the vessel contents is characterized by a keyboard (12), a display (14), reference signal generation circuitry and a microcomputer (16) operatively connected to the keyboard (12), the display (14), the heating element and the reference signal generation circuitry. The microcomputer (16) is programmed to receive indications of desired cooking temperature and cooking time, and to initiate a cooking cycle only after the temperature of the vessel contents has initially reached the desired cooking temperature. In three modes of operation the heating element (32) is cycled on and off to maintain the desired cooking temperature. In a fourth mode of operation the heating element (32) is constantly on during the cooking cycle. When the cooking cycle has ended, the heating element (32) is de-energized and a tone is sounded.</p> |
