Product Information:

A Tunnel Drying Furnace is an industrial-scale continuous drying equipment designed for large-volume production. It uses chains, mesh belts, or step-by-step mechanical conveying systems to continuously transport materials into the tunnel chamber.During the conveying process, materials exchange heat with hot air or infrared radiation inside the tunnel, achieving efficient and continuous dehydration and drying.The equipment features continuous operation, precise temperature control, uniform heating, and high production efficiency, making it suitable for various industrial drying applications.

FAQ

Q1: Can the temperature of a tunnel drying furnace be controlled in different sections?

A: Yes. The furnace is usually divided into multiple sections, such as the preheating zone, constant temperature zone, and cooling zone. Each section can be independently set and controlled according to the drying process requirements.

Q2: How should the heating method (electricity, gas, or steam) be selected according to the material?

A:Electric heating provides the highest temperature control accuracy and a clean operating environment.

Natural gas heating offers lower operating costs.

If the factory already has sufficient steam supply, steam heating is usually the most economical option.

Q3: What is the difference between mesh belt and chain conveyor systems?

A:The mesh belt conveyor is suitable for drying bulk materials, granular materials, and small-sized products.

The chain conveyor or tray conveyor is suitable for transporting heavier materials, larger workpieces, and regularly shaped products.
