ABSTRACT:
A tray scrubber for plastic baked product trays or pans which automatically scrubs and cleans the bottom and sides of the tray, both on the interior and the exterior. A first pair of sides is cleaned in a first station as the tray travels along the machine and the interior of the tray is then brushed and subjected to a water spray. The tray is automatically rotated 90.degree., about an upright axis so that the sides that were originally leading and trailing in direction of movement are now along the edges of the conveyor moving the trays, and can be scrubbed on the exterior as well. The process is very rapid, and because it is fully automatic, can process a large number of trays for complete scrubbing in a short period of time.
