Abstract
A method and apparatus (10) for the heating of convective material contained within the lumen of an inductive heating coil (12, 15, 16, 17) such that the cans (20) are rotated about their axes as they are heated. When the cans (20) are to be heated above the boiling point of their contents the cans (20) are passed through a rotary pressure lock (13, 19, 22) so that the heating of the contents of the cans (20) occurs under a super-atmospheric pressure.
Claims36
A method for the heating of a liquid or a material disposed in a liquid, contained within a metallic can, the method including the steps of passing the can longitudinally through the lumen of a helically wound induction coil, heating the can within the lumen of the induction coil, while simultaneously rotating or oscillating the can.
Apparatus for the heating of a convective material contained within a metallic can, the apparatus including a helically wound induction coil adapted to induce heating in the wall of the can, means to cause cans to move longitudinally through the lumen of the coil, and means to cause the cans to rotate about their own axes as they are passed through the coil.
