Rotary dryers are a highly efficient industrial drying option for bulk solids.The heatless desiccant dryer is the most expensive to operate as 15-20 of its rated flow capacity is consumed as purge air. The rotary drum dryer can lead to significant energy savings because of its unique design and controls. Even compared to a blower purge dryer, rotary drum dryers can save up to 50 of the lifecycle cost.
