Abstract:
A thermal processor having a contaminant removal system. The system includes a heated drum for heat developing exposed heat developable media which emit airborne contaminants during the development; a plurality of rollers located about a circumferential segment of the drum to hold an exposed media in contact with the drum; an enclosure for enclosing the heated drum and plurality of rollers, the enclosure including a first upper curved member spaced from and enclosing the rollers and the upper portion of the drum and a second lower curved member spaced from and enclosing the lower portion of the drum, the first and second curved members having first ends spaced from each other and defining a film entrance region, and further having second ends spaced from each other and defining a film exit region; wherein the first upper curved member includes a curved duct having a first opening above the rollers and a second opening configured to direct gaseous fluids away from the film exit from the drum. The system further includes a top condensation trap communicating with the second opening of the duct; a bottom condensation trap; and an air flow control system for drawing ambient air from outside the enclosure through the film entrance region, splitting the air flow into (a) a top flow stream which passes between the first member over the rollers, through the duct and through the top condensation trap where airborne contaminants are condensed and the air stream is cooled, and (b) a bottom flow stream which passes between the second member and the lower portion of the drum and through the bottom condensation trap where airborne contaminants are condensed and the bottom flow stream is cooled.
