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.

Ultraviolet radiation drying enclosure comprising a generally cylindrical wall containing said ultraviolet radiation lamp in a radiation plane parallel to the generatrices of said cylindrical wall and perpendicular to the longitudinal plane of symmetry wherein the profile of the transverse cross-section of said cylindrical wall is at least in part formed by elliptical arcs which have a common first focus on the axis along which said radiation plane intersects said longitudinal plane of symmetry and respective second foci staggered heightwise perpendicularly to said radiation plane.
