Abstract: A conveyor belt washer for cleaning a moving conveyor belt with a pressurized fluid. The conveyor belt washer includes a washtank, a spray assembly located within the washtank and having at least one spray head rotatably mounted with respect to the tank, and at least one splash plate defining a substantially planar splash surface mounted within the washtank and positioned on the opposing side of the conveyor belt from that of the spray assembly. The splash surface is sized to substantially correspond with the circular path defined by the rotatable spray head whereby pressurized fluid passing through the belt is continuously redirected against the opposing side of the conveyor belt upon contact with the splash surface.
