A method for operating an electric heating system of a kitchen machine and a kitchen machine for carrying out the method are proposed, wherein a measuring temperature of the heating system is determined by means of a temperature element in order to carry out a calibration of a heating element and/or to compare the measuring temperature with a heating temperature of the heating element determined by means of the heating element for identifying a critical heating state.

Method for operating a heating system and kitchen machine

The application relates to food preparation apparatus with an electrical heating device comprising at least two electrical PTC thermistors for heating a food in a food preparation space, wherein the electrical PTC thermistors are electrically connected in parallel. The parallel-connected PTC thermistors are electrically connected to each other by one or more electrical bridges. Using designs in accordance with the present application, local heating during the preparation of a food may be avoided.

Food preparation device with parallel electrical cold conductors

The present disclosure relates to food preparation apparatus with an electrical heating device comprising at least two electrical PTC thermistors for heating a food in a food preparation room, wherein the electrical PTC thermistors are electrically connected in parallel. The parallel-connected PTC thermistors are electrically connected to one another by one or more electrical bridges.

Food preparation apparatus with electrical PTC thermistors connected in parallel

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 T, Tof 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 T(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.

Food processor with boiling point recognition

The present invention relates to a cooking pot for a food processor with a heating element, wherein the heating element includes a heating device for generating heat and a heat exchanger with a heat-absorbing side at which the heat exchanger is heatable by the heating device and a heat emission side for heating of foodstuff in the food processor. The heat exchanger includes an opening for a stirrer and a first functional layer at the heat emission side. The heat exchanger includes at least partially a metallic heat conducting layer, which is arranged with the first functional layer such that the heat generated by the heating device is transferable extensively from the heat conducting layer to the first functional layer.
