Description

Technical Field

[0001] The utility model relates to the technical field of tunnel furnaces, in particular to an exhaust structure of a tunnel furnace. Background Art

[0002] A tunnel oven is a tunnel-type mechanical equipment that bakes food through heat conduction, convection, and radiation. The oven body is generally very long, with a minimum of 6 meters and a maximum length of 60 to 80 meters. The baking chamber is a long and narrow tunnel with a width of generally 80 to 140 centimeters. There is a continuously operating conveying system in the tunnel. When food is baked, the food moves relative to the electric heating element or direct-burning combustion rod through the conveyor chain plate, steel belt or mesh belt, thereby completing the work of uniform baking and conveying. However, some existing tunnel ovens need to discharge the internal hot air through the exhaust channel during processing. Since the heat of the gas is higher than one hundred to one hundred and fifty degrees when it is discharged, a greenhouse effect occurs, and the gas itself also emits radiant heat to the outside, thereby reducing the use effect.
