A method of treatment of a medium using sound waves of ultrasonic frequency, and an apparatus for performing said treatment 1, is disclosed. The apparatus 1, which comprises an ultrasonic generator 7 and ultrasonic transducers (22, 23 figure 3) located in abutment with a container wall (24, figure 3), may include a heat exchanger 3, 4. The treatment may be applied to a liquid and/or solid foodstuff, optionally placed in a flavoured liquid, and optionally subjected to agitation further to that generated by the ultrasonic waves. The apparatus may comprise a chiller 8 for subsequent cooling of the foodstuff. The ultrasonic transducers (22, 23 figure 3) may be positioned in a 'V' shaped arrangement. |
