- the known methods are aimed primarily at on optimizing the Eigent ⁇ Liche roasting phase in view of the coffee flavor. This is preferably done in a controlled roasting phase.
- the roasting is designated with a predetermined time profile of the temperature between a predetermined roasting start temperature and a predetermined roasting end temperature.
- a predetermined time profile can be implemented, for example, by means of a temperature control by comparing the measured value of a temperature probe, that is to say of a measuring sensor which allows conclusions about the temperature, to a predetermined setpoint value. If a difference occurs between the setpoint and the actual value, the controller must counteract this.
