Treatment of commodities through contact with fluid media

Claim 1

Apparatus for subjecting commodities to treatment through contact with fluid media including a plurality of movable conveyances having walls and being arranged so as to form a conveyance train which forms a part of a single endless fluid conveying duct, having walls and opposite ends, with the walls of said part of said duct formed by the walls of said conveyances, in which the treatment to which the commodities is to be subjected takes place with fluid passing progressively through the conveyances forming the conveyance train, a fluid inlet station means and a fluid outlet station means at opposite ends of the conveyance train and between which the conveyance train is located, and a circulating duct which links the outlet station to the inlet station as a portion of the endless duct.

Claim 12

A method of treating commodities by contact with a fluid media in an apparatus, said apparatus comprising a plurality of movable conveyances having walls and arrangeable so as to form a conveyance train which forms part of a single endless fluid conveying duct having walls and opposite ends, with the walls of said part of said duct formed by the walls of said conveyances, a fluid inlet station means and a fluid outlet station means at opposite ends of the conveyance train and between which the conveyance train is located, and a circulating duct which links the outlet station to the inlet station as a portion of said endless duct, said method comprising the steps of placing said commodities in said conveyances, arranging said conveyances to form said conveyance train, passing said fluid media from said inlet station means to said outlet station means through said conveyance train, removing at least one conveyance adjacent the inlet station means from position as part of said duct once the commodities in said conveyance having been sufficiently treated, advancing said conveyance train towards the inlet station means, and coupling the required number of freshly laiden conveyances into said train adjacent said outlet station means to reform said duct.

Claim 13

A method of treating commodities by contact with a fluid media in an apparatus, said apparatus comprising a plurality of movable conveyances having walls and arrangeable so as to form a conveyance train which forms part of a single endless fluid conveying duct having walls and opposite ends, with the walls of said part of said duct formed by the walls of said conveyances, a fluid inlet station means and a fluid outlet station means at opposite ends of the conveyance train and between which the conveyance train is located, and a circulating duct which links the outlet station to the inlet station as a portion of said endless duct, said method comprising the steps of placing said commodities in said conveyances, arranging said conveyances to form said conveyance train, passing said fluid media from said inlet station means to said outlet station means through said conveyance train, removing at least one conveyance adjacent the inlet station means from position as part of said duct once the commodities in said conveyance having been sufficiently treated, advancing said conveyance train towards the inlet station means, and coupling the required number of freshly laiden conveyances into said train adjacent said outlet station means to reform said duct.

Claim 15

A method of treating commodities by contacting same with fluid media in apparatus including an endless duct means for conveying said fluid media, said duct means including as part thereof a plurality of conveyance means having walls forming a portion of said duct means, fluid inlet station means and fluid outlet station means, said conveyances movable in a direction from said fluid inlet station means towards said fluid outlet station means, said conveyance means located between said station means, circulating duct means which links the outlet station means to the inlet station means as a portion of said endless duct means, and means to pass said fluid media through said fluid inlet station, said plurality of conveyance means, and said fluid outlet station to contact said commodities during passage through said conveyance means, said method comprising the steps of placing said commodities in said conveyance means, arranging said conveyance means to form said endless duct means, passing said fluid media from said inlet station means to said outlet station means, removing at least one conveyance adjacent the inlet station means from position as part of said endless duct means once the commodities in said conveyance means have been sufficiently treated, advancing the remainder of said conveyance means between said inlet station means and said outlet station means toward said inlet station means, and coupling the required number of freshly laiden conveyance means into said endless duct means adjacent said outlet station means to reform said endless duct means.

Claim 16

A method of treating commodities by contacting same with fluid media in apparatus including an endless duct means for conveying said fluid media, said duct means including as part thereof a plurality of conveyance means having walls forming a portion of said duct means, fluid inlet station means and fluid outlet station means, said conveyances movable in a direction from said fluid inlet station means towards said fluid outlet station means, said conveyance means located between said station means, circulating duct means which links the outlet station means to the inlet station means as a portion of said endless duct means, and means to pass said fluid media through said fluid inlet station, said plurality of conveyance means, and said fluid outlet station to contact said commodities during passage through said conveyance means, said method comprising the steps of placing said commodities in said conveyance means, arranging said conveyance means to form said endless duct means, passing said fluid media from said inlet station means to said outlet station means, removing at least one conveyance adjacent the inlet station means from position as part of said endless duct means once the commodities in said conveyance means have been sufficiently treated, advancing the remainder of said conveyance means between said inlet station means and said outlet station means toward said inlet station means, and coupling the required number of freshly laiden conveyance means into said endless duct means adjacent said outlet station means to reform said endless duct means.
