Process Advantages of Indirect Heat Dryers

Process Advantages

• Product is isolated from the burner flue gases.

• Material is heated through radiation and conduction.

• Processing material is contained in an atmosphere that can be controlled through the introduction of nitrogen or other gas to facilitate or retard a reaction inside the rotating drum.

• The LDC IDHD can be designed with heating zones that can have different temperatures allowing sequentially staged and controlled reactions inside the rotating drum.

• Light density, or very fine materials can be processed without the fear of them being swept out of the rotating shell.

• High product temperatures can be achieved through a combination of burner sizing and/or varying residence times.
