Abstract: An improved scrubber that uses a stream of air to blast the oil off the oil-laden conveyer chains of oil-only recovery apparatus is disclosed. The improved scrubber eliminates the need for conventional scouring components that physically contact the conveyer chain. The scrubber includes a blower, a series of air ducts, and an elongated nozzle. The air flow generated by the blower is communicated through the air ducts and directed onto a length of the oil-laden conveyer chain within the reservoir chamber of the recovery apparatus by the nozzle to blast the crude oil off the conveyer chain. The scrubber also includes a collection baffle positioned directly behind the length of the conveyer chain, which provides a surface area upon which the liquid oil collects and upon which the gaseous oil particulate may agglomerate and condense, before collecting at the bottom of the reservoir chamber.
