Microwave arrangement for heating material

摘要

A microwave arrangement for heating material in a continuous process. The microwave arrangement 1 comprises a circular-cylindrical resonator 2 in which a field configuration is generated so that areas having a maximum field energy are created in the resonator 2. By passing low-dielectric loss materials 14 a plurality of times along a helical path through these areas, the efficiency is significantly improved. An embodiment which is particularly suitable for drying wire or tape-form materials 14 comprises a rotatable circular-cylindrical reel 8 via which the materials 14 are conveyed to the areas.
