ABSTRACT:
The invention relates to a heating arrangement for packing containers (5) which hold a liquid beverage. The heating arrangement functions in such a manner that induction currents are induced in an aluminium foil layer which is laminated into the packing material at the same time as a mechanical movement is imparted to the packing container (5) in order to bring about a circulation of the beverage. The induction currents are produced with the help of an inductor (1, 7, 10) which subjects selected, jointless parts of the packing container to a high-frequency electromagnetic field.
