    One of the most common types of indirect-heat rotary dryers is the steam-tube rotary dryer, shown below. It consists of a slowly rotating, almost horizontal shell with heat-transfer tubes along the outside walls. Steam enters the heat-transfer tubes through an inlet at the discharge end of the dryer

    Rotary dryers are a highly efficient industrial drying option for bulk solids. They are often chosen for their robust processing capabilities and their ability to produce uniform results despite variance in feedstock. Rotary dryers work by tumbling material in a rotating drum in the presence of a drying air. They can also be indirectly heated
