Claim:
1. An HMA producer comprising: a. an outer housing having a material inlet on a top of one side and a material exit at a bottom of a side opposite and having an outer housing length; b. an inner drum having cylindrical shape with a diameter and capable of rotation within the outer housing, an end of the inner drum proximate the side of the outer housing by the material exit having an opening and the inner drum having an inner drum length; c. the inner drum and the outer housing having space there between, said space from proximate the material inlet to proximate the material outlet defining a material transfer chamber; d. at least one idler structure about a circumference of the inner drum, the at least one idler structure supporting the inner drum and further comprising: d. a pipe with a smaller diameter than the inner drum, coaxially extending oppositely from the inner drum end proximate the material inlet, connected to said inner drum end by a conical connector whose one end connected to the end rim of the inner drum proximate the material inlet and the other end connected to the pipe body; and e. at least one stationary heating unit located inside the inner drum; wherein materials enter into the chamber through the material inlet and move through the chamber toward the material exit and the stationary heating unit indirectly heats the material through the inner drum while the material traverses the chamber and the thrust roller arrests vertical moments of the inner drum caused by an accumulation of material in a lower portion of the material transfer chamber.
