Abstract
A process and apparatus to control the cooking process in a steam pressure cooker heated with a heating element controlled through a control circuit wherein the temperature of the pressure cooker is detected and utilized by the control circuit to regulate the heat output of the heating element, and wherein a cooking time can be preset by means of an adjustable timing element. To automatically adjust the preset cooking time for the time constants of the cooking system dependent upon the nature and quantity of cooking material, the slope of the temperature-time characteristic line of the entire system is detected in the heating phase, the time period which elapses between reaching the temperature of the beginning of the vapor phase and the evaporation temperature of the water in the pressure cooker is measured, and the preset cooking time is adjusted depending upon the detected slope and the determined time period and is shortened by a time interval that is greater, the smaller the slope and the greater the determined time period.
