HIGH EFFICIENCY APPARATUS AND METHOD FOR COOKING, HEATING AND DRYING

摘要

An apparatus and method for cooking, heating, or drying in which, as items or materials are conveyed through a heating chamber by a linear, spiral, or other type of conveyor, hot combustion product gases are delivered upwardly through an upwardly extending first annulus or other flow gap which is closest to the conveyor. The hot combustion product gases are then delivered downwardly through the heating chamber into contact with the items or materials on the conveyor. Next the combustion product gases are delivered from the lower portion of the heating chamber into the lower portion of a second annulus or other flow gap or passage. The second flow gap or passage is separated from the heating chamber by the first annulus or other flow gap. Subsequently, the combustion product gases are delivered upwardly through the second flow gap or passage.

主权项

1. An apparatus for cooking, heating or drying comprising:
a housing; a heating chamber within the housing for cooking, heating, or drying; a conveyor extending through the heating chamber; an upwardly extending first wall of the housing; an upwardly extending interior heating chamber wall of the housing inside of the upwardly extending first wall, wherein the upwardly extending heating chamber wall faces the conveyor; an upwardly extending intermediate wall of the housing between the upwardly extending first wall and the upwardly extending interior heating chamber wall; an upwardly extending inner flow gap which is formed between the upwardly extending interior heating chamber wall and the upwardly extending intermediate wall; an upwardly extending outer flow gap which is formed between the upwardly extending intermediate wall and the upwardly extending first wall; and a flow path defined in the housing for combustion products, wherein the flow path travels through the upwardly extending inner flow gap, the heating chamber, and the upwardly extending outer flow gap.
