Abstract
The method serves for operating a cutting device, which is designed for cutting a process material, particularly foodstuff and which has at least one blade, which is driven by a drive device and to which ultrasonic energy is supplied from a ultrasound unit via at least one energy converter and a coupling element. A control unit is provided, which controls the ultrasound unit in such a way, that the frequency of the ultrasonic energy which is supplied to the blade via only one coupling element is keyed between at least a first and a second operating frequency or that the ultrasonic energy is supplied to the blade via a first coupling element with a first operating frequency and via a second coupling element with a second operating frequency, which frequencies are fixed or keyed between at least two operating frequencies.
