A continuous vapor phase processing system of the type wherein work is selectively heated by a processing vapor in a processing vapor zone to a preselected temperature for vapor phase processing, comprising: a vessel containing a processing vapor in a processing vapor zone, a first aperture in the vessel side wall within the vapor zone and below the upper level of the processing vapor zone and by which a work product is introduced into the processing vapor, and a second aperture in the confronting vessel side wall within the vapor zone and below the upper level of the processing vapor zone and by which a work product is removed from the processing vapor; a first conduit in communication with the first aperture and extending outwardly from the vessel side wall and having an outer end open to the atmosphere; a second conduit in communication with the second aperture and outwardly extending from the confronting vessel side wall and having an outer end open to the atmosphere; each of said conduits having a cross-section and a length selected to allow passage of a work product therethrough and to provide an intended flow resistance to impede the outward flow of the processing vapor in the conduit and significantly prevent the exit thereof to the atmosphere; first means associated with each of said apertures for cooling the region of the vessel adjacent the apertures to below the condensation temperature of the processing vapor to prevent significant processing vapor from entering respective conduits; second means respectively disposed on and extending along at least a portion of the length of said conduits for cooling the processing vapor therein to below the condensation temperature therefor to significantly prevent said processing vapor from exiting the conduits to the atmosphere; means for conveying a work product through said first conduit into the processing vapor zone of said vessel and out of the vessel through said second conduit; and said first and second conduits being substantially in alignment on respective sides of the vapor zone of the vessel to provide substantially straight-through conveyance of the work product through the first conduit into the processing zone of the vessel and out of the vessel through the second conduit.
