Hot air is circulated inside the tunnel furnace through fans

Tunnel furnace drying line is a drying equipment widely used in multiple fields of industrial production. Its working principle is mainly based on the principles of heat conduction and convection. Heat is generated through the heating elements inside the tunnel furnace, and the hot air circulation is used to transfer the heat to the surface of the material, thereby achieving the purpose of drying.

Firstly, the heating system of the tunnel furnace drying trunk line is its core component. It usually uses electric or gas heating methods to convert electrical or chemical energy into thermal energy through heating elements. These thermal energies are further transferred to the air inside the furnace, causing the air temperature to rise and forming hot air.

Next, the hot air is circulated inside the tunnel furnace through a fan. The function of the fan is to suck in hot air from one end of the furnace chamber, then reheat it through the heating element and send it out from the other end. In this way, the hot air forms a continuous circulating flow in the furnace, ensuring that the material can receive heat evenly.

In terms of material transportation, tunnel furnace drying trunk lines usually use equipment such as conveyor belts or drums. These devices are able to smoothly feed materials into the tunnel furnace and maintain continuous movement of the materials during the drying process. In this way, the material can continuously come into contact with hot air, thereby achieving a drying effect.

In addition, the tunnel furnace drying line is also equipped with temperature and humidity control systems. These systems can monitor the temperature and humidity inside the furnace in real time, and automatically adjust according to the characteristics of the materials and drying needs. By controlling the drying conditions, it is possible to ensure that the materials are dried in the environment, avoiding situations of over drying or over wetting.

Overall, the working principle of tunnel furnace drying trunk line is a comprehensive process involving multiple aspects such as heat conduction, convection, and material transportation. It uses heating elements to generate heat, which is transferred to the material through hot air circulation. At the same time, it is combined with material transmission equipment and temperature and humidity control system to achieve uniform drying effect. This working principle makes the tunnel furnace drying line have broad application prospects in industrial production.
