<p>A machine for automatically spreading an even layer of shredded or particulate products on relatively large flat items includes a surface comprising either a shaker tray or, preferably for sticky products, a stationary louvered air pan positioned over a conveyor line extending through an open-ended rotating drum. Elongated rake-like members circumferentially spaced around the inside of the drum carry portions of the products from the bottom of the drum to a discharge point above the shaker tray or air pan. Oscillations of the tray or a cushion of air fed from a plenum below the louvered pan cause the products to move laterally and to cascade evenly over a lip that extends diagonally across the conveyor line to cover items transported along the line. Features of the apparatus include a torsional stabilizer to prevent racking of the shaker tray by unequal actuator forces, a specially shaped plenum to produce uniform air velocity across the louvered pan, adjustable rake members that are easily removed for cleaning, air blast discharge of products from the rakes onto the tray, and a conveyor transfer station at the exit end of the drum to prevent excess product carryout.</p> |
