  • Patent number: 11311142
    Abstract: The present disclosure relates to a food processor for preparing a food in a pot. The food processor comprises the pot, a heating element for heating the pot or a food in the pot, and a temperature sensor for detecting a temperature TSUR, TMED of the pot or a food in the pot. The food processor comprises a monitoring device which is configured such that the monitoring device can detect an exceeding of a boiling point SP of a food in the pot on the basis of a temperature measurement value TNTC(k) of the temperature sensor and an electrical measurement value u(k), which depends on an energy supply to the heating element. Furthermore, the present disclosure relates to a process and a computer program product. A food processor with boiling point detection can thus be made available with particularly low production effort.
