Title: High velocity, hot air dryer and extractor

Abstract: A hot air dryer utilizes high velocity air jets which scrub and break upthe moist air layer which clings to the surface of a freshly printedsheet. High velocity air is heated to a high temperature as it flows alonga resistance heating element within an air delivery baffle tube. Theheated, high velocity air pressurizes a plenum chamber within an airdistribution manifold. High velocity jets of hot air are dischargedthrough multiple air flow apertures onto the wet ink side of a printedsheet as it moves through the dryer exposure zone. An extractor removesthe moist air layer, high velocity hot air and volatiles from the printedsheet and exhausts it from the press.
