ABSTRACT:
Method and apparatus for operating a conching device with a trough (1) in which at least one rotor, driven by at least one electric motor (9), is arranged. This rotor is fitted with refining tools spaced apart in axial distances to one another around its periphery. The driving motor is controlled by means of a motor control unit in dependency upon a difference signal of a performance-regulating circuit (22), gained by comparison (6) between a desired nominal value (7) and an actual value (5) of at least one motor performance parameter (22).
To perform the conching process in the minimum possible time, it is provided that the difference signal of the performance-regulating circuit (5-8) remains ignored during at least a time interval. Thus, the driving motor (9) can take a maximum motor current, and it runs up to the speed required within a very short time.
