Abstract:
1. An ultrasonic sonotrode for irradiating ultrasonic energy into fluid or pasty media, wherein the ultrasonic sonotrode in a longitudinal direction (z) comprises: a coupling section for coupling an active ultrasonic system which excites longitudinally in the longitudinal direction (z); a base section, wherein a largest dimension of the base section transverse to the longitudinal direction (z) is larger than a length of the base section in the longitudinal direction (z), wherein dimensions of the base section transverse to the longitudinal direction in a border region to the transition section are always ≧λ/4 and a shortest length of the base section in the longitudinal direction (z) is <λ/4; a transition section for the reduction of a cross section in at least one cross-section with respect to the base section; and a flat section with an end-face region as an irradiation surface, wherein the flat section is divided by way of at least one slot into several tongues which are unconnected in the end-face region.
