Abstract
Heating apparatus, particularly for heating materials contained within drums or similar containers, has a metal base plate 12 with an induction heating coil 16 beneath the plate. The container 24 to be heated is placed on the base, and may be surrounded by a cylindrical jacket 28 with a further induction coil 34 in the jacket wall. On energising the coils, induction currents flow in the metal base plate (and in the jacket wall) to produce heat which is transmitted to the container and its contents. In another embodiment, the base plate may just receive heat energy from a jacket coil.

1-16. (canceled)
Heating apparatus for heating a product within a container, the apparatus comprising a metal base plate above which the container can be supported, an induction coil arranged beneath the plate, the induction coil being wound around an insulating core which supports the base plate, and means for supplying the coil with alternating current to induce a current into the base plate to heat the base plate.
Heating apparatus comprising a cylindrical jacket having at least one induction heating coil sandwiched between inner and outer shells, and a metal base plate located within the jacket, above the bottom edge of the coil, such that on energising the coil, induction currents flow in the metal base plate.
