A processor for vacuum distillation of whole tires including: an insulated housing having a door on one end, a central radiant heat tube and a plurality of peripheral heat tubes spaced about the central radiant heat tube and arranged with an inlet leg of each peripheral heat tube adjacent an outlet leg of another peripheral heat tube to maximize utilization of the radiant heat energy from the peripheral heat tubes. The central radiant heat tube has an unsupported end adjacent the door such that the tires loaded through door will pass over the central radiant heat tube and such that the central radiant heat tube is in a central opening of each tire.
