ABSTRACT:
A system to control and regulate heat output during the heat-up phase of a pressure cooker heated by a heating element which can be turned on and off by means of a control circuit. The heat-up phase is adjusted, depending on the rate of temperature increase before it reaches the boiling temperature, and is controlled by a different program after the boiling temperature is reached, which determines rates of further temperature increases and also the temperature differentials between a preset cooking temperature and the current cooking temperature. Using this apparatus, the cooking temperature can be reached as quickly as possible, regardless of the characteristics of the heating phase, dependent upon the type and amount of cooking material in the pressure cooker. Energy utilization efficiency can be increased and the preset cooking temperature not exceeded.
