Tunnel Drying Furnace
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.
Applications
1. Food Industry
Drying of dehydrated vegetables, dried fruits, meat products, puffed foods, and other food materials.
2. Electronics and Semiconductor Industry
Curing of PCB coatings, adhesive dispensing curing of electronic components, and semiconductor drying processes.
3. Pharmaceutical and Chemical Industry
Drying of traditional Chinese medicine slices, pharmaceutical granules, powders, catalysts, and other materials.
4. Hardware Surface Treatment
Drying of surface moisture and curing of coatings after electroplating and spraying processes.
