What Is a Rotary Drum Dryer?
A rotary drum dryer is a type of industrial drying machinery that uses a cylindrical drum to dry materials or gases. This dryer operates by introducing these elements into the drum and using hot air or compressed heat to evaporate moisture.
The drying process involves agitating the materials or gases inside the rotating drum, equipped with lifters, to ensure consistent heat exposure. The drum’s length and diameter are typically tailored to suit the specific drying requirements of different materials, allowing for its use with a diverse range of substances. This adaptability, combined with its capacity for large-scale processing and continuous operation, makes the rotary drum dryer highly efficient for mass production.
Rotary drum dryers that use compressed heat for drying air are particularly energy-efficient. However, they may not be as effective for materials with high viscosity, which often require extended heating at elevated temperatures for proper drying.
