Abstract: A tray denester for separating individual trays from a stack. The tray denester includes a product carrier plate that is movable toward and away from the discharge end of a product magazine. The product carrier plate includes a pair of air nozzle assemblies. As the product carrier plate moves toward the discharge end of the magazine, the air nozzle assemblies are activated to create a low-pressure zone along the product carrier plate. When the product carrier plate reaches the discharge end, an escapement mechanism releases the stack of trays. As the stack of trays is released, the low-pressure zone separates one of the trays from the stack. The separated tray contacts the product carrier plate and is removed from the stack. Each of the air nozzle assemblies is adjustable along the product carrier plate to vary the position of the air nozzle assemblies based upon the specific tray design.
