An improved flash dryer oven is disclosed which operates in a self-cleaning manner that continuously removes dust and debris from the oven, thereby preventing dust and debris from interfering with the hot air flow through the oven. A self-cleaning function is provided to the flash dryer oven by routing the conveyor belt through the lower supply duct on its return path to continuously clean out lead oxide dust and particles that are located within the lower supply duct. In addition, the lower supply duct has a gabled top that will direct some of the lead oxide dust and particles off of the lower supply duct instead of the lead oxide dust and particles falling through nozzles in the top of the lower supply duct and into the lower supply duct.
