Abstract
An apparatus and method for coloring aggregate wood material by directing a flow of material onto vertically spaced, perforate conveyors with each conveyor served by conduits discharging curtains of liquid dye. A drive system for the conveyors includes the provision of driving the conveyors at different speeds to increase aggregate depth for saturation purposes. Conduits of the spray system have oversized orifices directing discharges onto deflectors for curtain formation. Curtain impingement includes the aggregate material in transition in between conveyors. An inclined conveyor and pan returns dye removed from the material to a catch basin.
