What are the structures of the infrared tunnel furnace body?

Tunnel furnace (food processing category) is a tunnel type mechanical equipment that completes food baking through heat conduction, convection, and radiation. The oven body is generally very long, ranging from 6 meters to 60-80 meters. The baking room is a narrow tunnel with a width generally ranging from 80cm to 140cm. There is a continuous operating conveying system inside the tunnel. During food baking, relative motion occurs between the food and the electric heating element or direct combustion rod through the conveyor chain plate, steel belt or mesh belt. Thus completing the work of uniform baking and conveying. This type of oven can be continuously produced, with high production efficiency, saving manpower, and stable baking quality. This tunnel furnace is mainly used in industrial food enterprises, characterized by large-scale continuous or intermittent baking. Normally, the rated power input is greater than 24KW and operated by dedicated personnel.

Tunnel furnace manufacturer

There are two main types of infrared tunnel furnace bodies for drying trunk lines: brick structure and steel plate structure. The choice should be determined based on the specific situation of each factory.

1. The furnace body is installed in the bottom workshop, and refractory bricks can be used as the main structure. The furnace body of refractory bricks has good deep temperature properties, strong heat storage capacity, and even and fresh bread baking color. On the contrary, ovens with poor heat storage make the finished bread baked in a dead gray color.

2. The oven installed on the floor building should be made of steel plate structure, and insulated with aluminum silicate and expanded perlite to reduce the weight of the oven. As long as the selection and arrangement of heating elements are reasonable, and the insulation performance is good, satisfactory results can also be achieved.

3. The selection of furnace top generally has two types: flat top and curved top. From the perspective of furnace body structure, it is advisable to choose a brick structure with a dome. If using a steel plate structure for the furnace body, a flat top is preferable. But from the actual baking quality, the dome is superior to the flat roof, and the baked bread has even firepower and excellent color.
