Method for inductively heating a galette and inductively heated galette

摘要

In a known inductively heated galette, the temperature is in each case controlled in a plurality of heating zones by means of the heating power. In this galette, due to the temperature sensor, the measured value transmitter and the controller, the outlay is large for each heating zone. A method for inductively heating a galette and a corresponding galette are to be developed, in which a temperature profile with deviations smaller than 1.5 DEG C can be set with as little outlay as possible. In the method according to the invention, at least two heating zones are combined to form a heating group, the temperature of each heating group is measured and is controlled by the heating power of a selected heating zone of the heating group. The heating power of the remaining heating zones of the heating group is in each case fed as a function of this heating power. The method according to the invention results in an improved temperature profile and, due to lower device costs, to less outlay.
