Abstract
A system and method for identification of a medium in a cooking vessel is disclosed. The system includes a cooking vessel, a heat source for heating a medium within the cooking vessel, and a temperature sensor within the cooking vessel for measuring the medium temperature. A process controller is in communication with the temperature sensor and controls the heat source, and includes a processing unit and a storage unit. Data is input to the process controller through an input unit, and the temperature sensor sends a signal representing the medium temperature to the process controller. The process controller controls the heat source and applies heat to the medium, and also monitors the medium temperature in order to determine whether the medium is substantially water. The method first determines the temperature of a medium in a cooking vessel and initiates a cool detection process if the temperature of the medium is less than a predetermined temperature. If the temperature of the medium is above at least a predetermined temperature, the warm detection process is initiated. Next, the method determines if the medium includes water and provides an alarm if the media is substantially water.
