Abstract
Systems and methods for delivering a cooking medium in a cooking apparatus are disclosed. A delivery system includes a rotary valve having a rotary inlet and a plurality of rotary outlets. The rotary inlet is configured to be in fluid communication with a source of cooking medium and the plurality of rotary outlets are configured to be in fluid communication with a corresponding plurality of receptacles. A rotary position sensor generates a signal, having continuous angular position resolution, based on an angular position of the rotary valve. A controller receives the signal generated by the rotary position sensor and selectively places the rotary inlet in fluid communication with one of the plurality of rotary outlets based on the signal generated by the rotary position sensor. The rotary position sensor may include a Hall-effect sensor that functions at elevated operating temperatures associated with the cooking medium.
