Rotary Dryer Applications
Centrifugal fans are key components in industrial dryer (rotary, ring, flash, disk, batch, cascade, etc.) applications. The fans function as supply fans and exhaust fans for the dryer. On this page, we’ll focus on the rotary dryer to represent the broader set of industrial dryers. (Learn about spray dryers and calciner rotary kilns.)
Industrial dryers like the rotary dryer remove moisture in the production process of various foods, chemicals, biofuels, and other products. The rotary dryer is a large drum that rotates to dry the material with a direct combustion-heated gas stream. They can be designed to handle a wide range of materials with different sizes and levels of corrosion.
In the rotary dryer, a supply fan (blower) pushes clean, ambient air through the combustion chamber to pick up the heat from the combustion process (which also includes a combustion fan) as it flows into the rotating drum. The tumbling action of the drum showers the material through the hot gas to dry it. The system also has an exhaust fan, which pulls the gas through various other applications like cyclones, dust collectors, and scrubbers to address emissions for safety and compliance.
