Abstract

An induction heater for heating a material is described which has an alternating current carrying conductor 30 extending along an axis of rotation. Mounted about the axis are containers 32 which rotate about the axis and hold the material to be heated. A core 34 is provided encircling the alternating current carrying conductor 30. The core 34 guides the magnetic flux resulting from an alternating current flowing in the conductor 30 to induce a current in the inner sleeve 38 between the conductor 30 and core 34. Current flowing in the inner sleeve 38 is conducted to end plates 40 and 42 and through the containers 32. The containers 32 are heated by the electrical current induced by the magnetic flux in the core 34.
