They are Generally employed for mass or volume production. The material to be treated(dried/backed) are loaded uniformly on conveyor, which carries the material through the heated tunnel and dried material is taken out at other end.
They are electrically heated or having finned tube heat exchanger working on steam or thermic fluid heater.
The stand alone hot air generator, direct fired or indirect fired is also offered. The excaust blower takes care of fumes generated during the process. The dedicated electronic/electrical control panel is designed for controlling production and drying parameters. 
The material of construction are M.S., S.S, Aluminum depending upon process requirements
