1. A continuous flow, rotary processing apparatus for horizontal transport of material at a predetermined rate, comprising:
- a) a cylindrical enclosure, a central axis of which is oriented in a horizontal plane, said cylindrical enclosure being rotatable about said central axis, said cylindrical enclosure having a predetermined diameter and axial length, and further having first and second end walls, a cylindrical wall disposed between said first and second end walls, and at least one vane structure of a predetermined surface area disposed longitudinally on said enclosure cylindrical wall;
b) means to rotate said cylindrical enclosure at a constant predetermined rotational velocity;
c) means to allow ingress of material into said cylindrical enclosure, said ingress means being disposed in said first end wall;
d) an egress aperture disposed axially, with respect to said cylindrical enclosure, in said second end wall;
e) a hollow cylindrical chute disposed in said egress aperture and having a first open end extending into said cylindrical enclosure, and a second open end which is open to the exterior of said cylindrical enclosure; and
f) means to dislodge material resident in said cylindrical chute first end.

Abstract
A continuous flow, rotary processing apparatus for horizontal transport of material at a predetermined rate. Material from an infeed conveyor enters a continuous system including at least one rotary drum operating about a horizontal axis. Each drum has a perforated circumferential wall with lateral lifters to induce flow and tumbling motion to the enclosed material. A flow control mechanism at the discharge end of each drum controls residence time of the material being processed. Material is fed and discharges from each drum through axial openings in which the flow control devices are mounted.
