ABSTRACT:
An ultraviolet radiation drying oven comprises in succession along a conveyor adapted to carry the objects to be dried a loading station to which the objects must be introduced, a drying enclosure containing at least one ultraviolet radiation lamp and an offloading station from which the dried objects are evacuated. At the loading station, a masking arrangement prevents escape of ultraviolet radiation. The masking arrangement comprises a turnstile mounted to rotate above the conveyor about an axis perpendicular to the conveyor and comprising a plurality of radial panels delimiting between them airlock compartments in a similar manner to a revolving door.
