Alternating horizontal air flow oven
First Claim
1. An alternating horizontal air flow oven having an air heating apparatus in fluid communication with an enclosure having opposite walls and having an air recirculating flow control mechanism for forcing heated air through said enclosure wherein said air is alternatingly directed horizontally through said enclosure in a first cycle in one horizontal direction and in a second cycle in the opposite direction, said air heating apparatus including an air exhaust duct and a fresh air duct for controlling air temperature in said enclosure and said air recirculating flow control mechanism directing said air horizontally through said enclosure by supplying air through one side wall while withdrawing air from an opposite side wall in said first cycle and then withdrawing air from said one side wall while supplying air through said opposite side wall in said second cycle.

Abstract
An air flow chamber for cooking or chilling using alternating horizontal air flow has an air heating or cooling apparatus and an air recirculating flow control mechanism for forcing heated or cooled air through an enclosure wherein said air is alternatingly directed horizontally through said enclosure in a first cycle in one horizontal direction and in a second cycle in the opposite direction.

10. An alternating horizontal air flow oven having an enclosure for air heating a product and a plenum housing an air heater and an air flow control mechanism, said air heater being in fluid communication with outside air for control of air temperature in said enclosure and said enclosure having a pair of opposite side walls with a multiplicity of apertures therein, said side walls spaced from adjacent outer side walls generally parallel thereto to thereby provide a vertical air flow passageway therebetween, each said passageway being In fluid communication with duct work having control dampers therein for selectively alternating air flow therethrough by supplying air to said enclosure through one of said side walls while withdrawing air from said enclosure through an opposite side wall and then withdrawing air from said enclosure through said one of said side walls while supplying air to said enclosure through said opposite side wall.
