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
Aug 10, 2021 Rotary drum dryers can be designed to withstand extremely high temperatures and/or corrosive materials. A basic carbon stee l drum is designed to withstand inlet temperatures from 1,000 F

Regular Rotary Drum Maintenance. Regular maintenance may be easy to forget, but is critical to the life of a drum, whether it be a dryer, cooler, kiln, or granulator. Regular maintenance helps keep parts at their best, and can help in detecting potential issues before they pose a serious threat. FEECO highly recommends annual inspections to

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

An 18’ dryer drum is not the only option. Rotary dryer drums as small as 4’ diameter can evaporate anywhere from 200 – 500-lbs/hr. Rotary drums much smaller than this have efficiency losses so an alternate drying system may be more beneficial. Using the same example above, with a product at 50% mcwb, a small rotary drum dryer can take

A further improved prototype of a combined conduction–convection type rotary drum dryer used ambient air that was forced inside the drum in counter flow to the direction of the cascading grains. The grain was heated by conduction heating as drying proceeded and followed by convection heating as cooling occurred of the heated grain
