ABSTRACT:
A grain roasting machine includes an elongated hollow roasting drum mounted for rotation about its fore-and-aft longitudinally extending central axis and a burner for producing a roasting flame within the drum in a direction extending generally longitudinally of the drum from one end toward the other end of the drum. The flame is produced in the longitudinal direction but offset to one side of the central axis of the drum. Vanes disposed on the interior of the drum sidewall and extending longitudinally between the ends thereof carry grain placed in the drum along a first arcuate path which skirts the periphery of the flame and then drop the grain in a second linear path in which most of the grain falls across the drum and directly through the roasting flame before returning to the first path. The drum is constructed by welding or otherwise rigidly connecting a plurality of plates together at their longitudinal edges so as to form an endless ring-like structure which defines the continuous sidewall of the drum. Each of the plates has an integrally-formed flange, being connected to the plate along one of its longitudinal edges. The flanges extend generally radially inward toward the central longitudinal axis of the drum so as to define the grain carrying vanes.
