ABSTRACT:
Drum-type continuous washer for small parts in manufacture, e.g., fasteners. The parts, requiring oil and other soil removal, are tumble-washed therein, in steps in order: at an immersion station for tumbling the soaking parts in hot washing liquid; at a liquid-impingement station for loosening and spraying off the wetted soils by the force and cleaning action of impinged, hot sprays of continuously recycled washing liquid; at a drip-dry station for tumbling off excess liquid from within and without the individual tumbling parts, leaving them wet and hot; at a blow-dry station for rendering the hot parts damp by means of compressing and blowing-on hot, recycling-steamy atmosphere drawn from the process and preferably containing rust-inhibitor coating material; and at an evaporative dry (final dry) station for discharging the cleaned, hot, rust-proofed parts essentially moisture-free by flash drying.
