Claim:
A retort cleaning apparatus comprising: a) a blow-off nozzle having an air inlet port and an orifice, comprised of a plurality of laterally spaced, rectangular air jet pairs, b) an air passage extension tube having an inward coupler, and a heat-resistant outward coupler that attaches to the air inlet port on said blow-off nozzle, c) an air hose having an air inlet coupler, and an air outlet coupler that attaches to the inward coupler on said air passage extension tube, and d) an air compressor having a compressed air fastener that attaches to the air inlet coupler on said air hose, wherein said air compressor is equipped with a power switch that controls the operation of an electrical motor, wherein when the power switch is closed, power from a power source is applied to the motor which then allows pressurized air to flow through said air hose, said air passage extension tube and into and out of the orifice of said blow-off nozzle.
