Abstract

An apparatus for controlling and adjusting heat output during the heating phase of a steam pressure cooking vessel. The steam pressure cooking vessel is heated by an electric heating element and the temperature inside the steam pressure cooking vessel is measured. The heating element is controlled by a control circuit and a program memory which operates in a simple way at various preset rapid cooking or vitamin preserving cooking temperatures as a function of the heating characteristics and controls the heat output so that the selected cooking temperature can be adjusted and maintained constant in the simplest possible way without overshooting.
