[0002] The tunnel furnace is a tunnel type mechanical equipment which completes baking through heat conduction, convection and radiation. The baking chamber is a long and narrow tunnel, and the width is generally 80cm to 140cm. There is a continuous conveying system in the tunnel. The heated products are conveyed by the relative movement between the conveying chain plate, steel belt or mesh belt and the electric heating element or direct combustion rod, so as to complete the uniform baking and conveying. This kind of oven can continuously produce, has high production efficiency, saves labor, and has stable baking quality. The tunnel furnace is mainly used for industrial production, and is characterized by large batch continuous or intermittent baking.
