Abstract
A device for the control of the cooking process in a steam pressure cooker filled with water and the food to be cooked and heatable by means of a heating element controlled by a control circuit wherein the temperature of the pressure cooker is detected and utilized by way of the control circuit for the adjustment of the heat output of the heating element and in which by means of an adjustable timing element a cooking time can be preselected. The cooking time in the pressure cooker is maintained regardless of the inertia of the cooking system by the fact that a timing element begins measurement of the preselected cooking time only upon reaching a preset measuring temperature between the vapor phase temperature and the evaporation temperature of the water and, dependent upon the length of time that elapses between the reaching of the vapor phase temperature and the reaching of the vaporation temperature of the water in the pressure cooker, is so controllable that it causes disconnection of the heating element before the end of the preselected cooking time in proportion to the measured length of time between reaching the vapor phase temperature and the evaporation temperature of the w…
