Indirect Heat Dryer

Indirect heat dryer Introduction

Indirect heat dryer is widely used in industries like the building materials, metallurgy, chemical engineering and cement. It is made up of rotary part, raising board, driving device, supporting device and seal ring. The energy saving indirect heat dryer has strong adaptability for drying all kinds of materials with simple operation steps.

Indirect Heat Dryer Feature 

a. The indirect heat dryer has compact and simple structure and reasonable composition which increases the heat exchange rate between the materials and the heat energy and realizes good drying effect.
b. The little basic investment reduces the one-time input.
c. It works reliably with low energy consumption and high heat efficiency.
d. It’s easy to realize automation control, reduce labor staff and save labor resource.

Indirect Heat Dryer Principle 

Materials enter the inner side of the drum through the feeding device to realize current flow drying process, and they absorb heat from both inner drum and middle drum, which extend the drying time and realize the best drying condition. Finally, materials fall into the external layer of the drum from the other end of the middle layer, processing in a rectangle multi-loop way. The dried materials move quickly out of the drum under the hot air, while the wet ones remain because of their own weight. Materials are dried completely inside the rectangle shoveling plate and then cooled by the single drum cooler, thus finishing the whole drying process.
