Appl. No.:

8/783607

Inventors:

Duane H. Lauersdorf - Watertown WI
David A. Strand - Elkhorn WI

Assignee:

Wisconsin Oven Corporation - East Troy WI

International Classification:

A21B 100
F24C 1332

US Classification:

34224

Abstract:

A conveyor oven is capable of heating precisely and uniformly an article to be baked as the article is conveyed through the oven at a designated speed. Precise and uniform heating is promoted by 1) a combination supply/return duct assembly positioned above the conveyor and configured to promote uniform airflow towards the upper surface of the conveyor, and 2) discharge orifices configured to further promote uniform airflow from the supply ducts without generating whistling or other unpleasant noises. The arrangement of this supply/return duct assembly, incorporating both supply and return ducts in the same plane, also promotes a low profile oven--an important consideration in applications in which minimizing space is a priority. The profile of the oven is reduced further by placing the heating element beneath the conveyor and by configuring supply and return passages to circulate air between the heat source and the supply/return duct assembly using minimal space. This air recirculation, preferably enhanced by seals at appropriate locations within the oven, also significantly increases the oven's thermal efficiency and its ability to distribute heat uniformly.

International Classification:

F27B 910

US Classification:

219388

Abstract:

A conveyor oven has two insulated cabinets, each cabinet having two plenums for conducting heated air toward a printing plate that rests on a conveyor. The two plenums in each cabinet face each other and are substantially identical. Each plenum has a supply and return duct assembly located above the conveyor, and is supplied by a fan and heater arrangement located below and underneath the conveyor. An insulated intermediate chamber is disposed between the exit of the first upstream cabinet and the second, downstream cabinet. With this arrangement, the conveyor carries a printing plate through the first cabinet, where the plate is heated, then through the intermediate insulated chamber, where it is maintained at a heated temperature, and then into the second cabinet where it is again heated. It is then conveyed out of the second cabinet and out of the oven by the conveyor. The system is compact--so compact, in fact, that it permits a trailing portion of the printing plate to be heated in the first cabinet at the same time a middle portion is in the intermediate chamber, and a leading portion is heated in the second cabinet.
