ROTARY DRYERS
Large throughputs and high evaporative loads.

Operation:
Rotary cascade dryers have the feed materials pass through a rotating cylinder together with a stream of hot gas. Internal lifters or flights elevate the feed and drop it in a curtain from the top to the bottom cascading along the length of the dryer. Flights need to be carefully designed to prevent asymmetry of the curtain. Material moves from one end of the dryer to the other by the motion of the material falling due to the angle of inclination of the drum. Some rotary dryers are double and triple pass units where each drum is nested inside the previous drum.

Rotary louver dryers have the feed materials supported and moving over a set of louvers mounted to an external rotating drum. The hot gas is introduced into a tapered bustle below the feed ring. The air passes through the louvers and then the product before being exhausted from the dryer. The rotation of the drum causes the material to roll and mix providing intimate contact with the drying gas. Material moves from one end of the dryer to the other by the motion of rolling, some fluidization and due to the angle of inclination of the drum.

Feeding / discharge:
Automatic and continuous. Vibrators, screw feeders, rotary airlocks, double flap valves, gravity chutes

Feed Characteristics:
Powders, granules, non friable agglomerates, large solid particles. Low to high feed rates

Heat Source:
Steam, electrical, coal, liquid fuels, or gas

Exposure:
Mostly Direct. Flow is co-current or countercurrent for cascade dryers. Flow is a combination of through the bed, cross, co-current or countercurrent for rotary louver.

Residence time:
Controllable. Residence time can be altered by varying the speed of rotation of the drum and the drum angle. Fill can be varied. Fills are typically between 7% and 25% of the cross sectional area of the drum.

Extraction:
Normally induced. Systems can have combustion, forced and induced draft fans for operation.

Dust Collection:
Cyclones, baghouses, scrubbers, Electrostatic precipitators. Systems require dust collection.

Control:
PLC, infrequently solid state controllers. System controls on discharge temperature. Can modulate energy and feed.

Benefits:
High throughput
Low cost - Higher for Louver
Gentle handling for Louver dryer
Very intimate product contact for louver dryer
Robust
Can handle variations in feed although the product may be inconsistent
High temperature operation - can be refractory lined.
Unit can have integral cooling section.

Limitations:
Clogging although chains and knockers will reduce this
May cause size reduction due to attrition and impact
Inconsistent dried product characteristics
Poor energy efficiency - high losses in cascade units
Poor heat transfer in cascade units
High maintenance
Large real estate required
Many wear components
No implicit dust separation
