Das Messer (1A; 1B; 1C; 1D; 1E), das zum Aufteilen, insbesondere Schneiden oder Zerstäuben, eines Prozessguts unter Anwendung von Ultraschallenergie dient, umfasst eine Klinge (10) mit wenigstens einem Klingenflügel (101), welcher sich frontseitig zu einer Schneide (1011) hin verjüngt und rückseitig mit einem Klingenrücken (103) verbunden ist, der einander gegenüberliegende grössere Seitenflächen (103U, 1030) und an frei liegenden Enden kleinere Stirnflächen (103F) aufweist. Erfindungsgemäss ist wenigstens auf einer der Seitenflächen (103U, 1030) des Klingenrückens (103) ein erstes Endstück (1811) wenigstens eines in einem Bogen verlaufenden, vorzugsweise U-förmigen Kopplungselements (181; 182) angeschweisst, dessen zweites Endstück (1812) ein Verbindungselement (18121), vorzugsweise eine Gewindebohrung, aufweist, welches mit einem der Zufuhr von Ultraschallenergie dienenden Energiewandler verbindbar ist.
摘要:
The device (1), which serves for processing, in particular cutting and spraying, at least one processable product, in particular a foodstuff (8), comprises at least one blade (11) which can be connected to an ultrasound source via at least one coupling element (12) and an energy converter (13) and is fastened to a blade holder (2) which is connected to a drive device (4) held by a framework (6). According to the invention, the drive device (4) comprises a plurality of actuators (41,…, 46) which, on the one hand, are in each case connected to the blade holder (2) via a first rotary joint (31;…; 37) and which, on the other hand, are in each case connected to the framework via a second rotary joint (51;…; 57) in such a way that the blade holder (2) is held by the actuators (41,…, 46) alone and is displaceable and, if appropriate, rotatable within a work volume.

The method serves for operating a cutting device (1), which is intended for cutting a process material, in particular a food (8), and which has at least one blade (11), which is driven by a drive device (12) and to which ultrasonic energy is supplied from an ultrasound unit (4) by way of at least one energy converter (13) and a coupling element (15). The invention provides a control unit (6), which controls the ultrasound unit (4) in such a way that the frequency of the ultrasound energy supplied to the blade (11) by way of only one coupling element (15) is keyed between at least a first and a second operating frequency (f1a, f1b) or that the ultrasonic energy is supplied to the blade (11) at a first operating frequency (f1) by way of a first coupling element (15A) and at a second operating frequency (f2) by way of a second coupling element (15B), which frequencies are fixed or are keyed between at least two operating frequencies (f1, f2 or f1a, f1b; f2a, f2b).
摘要:
The cutter (1A; 1B; 1C; 1D; 1E) which is used to divide, in particular to cut or atomize, a processed product using ultrasound energy comprises a blade (10) having at least one blade wing (10) which narrows at the front to form a cutting edge (1011) and is connected at the rear to a blade back (103) which has mutually opposing larger side faces (103U, 103O) and smaller end faces (103F) at the exposed ends. According to the invention, there is provided on the blade back (103) or an extremity (1030) formed thereon a mounting face (105) on which there is welded a first end piece (1811) of at least one coupling element (181; 182) which extends in an arcuate manner and is preferably U-shaped, the second end piece (1812) of which coupling element (181; 182) has a connecting element (18121), preferably a threaded bore, which is connectable to an energy transducer that is used to supply ultrasound energy.
