Principles of Rotary Drying
The directly heated rotary dryer operates on the principle of lifting and showering the product through a hot gas stream moving either in parallel or counter-flow whereas with the indirect dryer, which is more suited to fine and dusty materials, there is little or no contact between the product and the drying gases since they are heated from the outside, via a stationary jacket fitted with either multiple burners or other external heat source.
The efficiency of the dryer is largely dependant on the differential between the inlet and exhaust gas temperatures, although the heat transfer rate is also influenced by the relationship between the design of flights and the speed of rotation. However, irrespective of the gas and material temperatures the drying (or residence) time may be critical, as this is governed by the rate of diffusion of water from the core to the surface of the material.
For special applications, the rotary cascade design is adapted to provide a shortfall, or 'Cruciform', lifter configuration.
Similarly, Rotary Cascade Coolers and Combined Dryer/Coolers are available as required.
Features of the Rotary Drying
Permits use of higher drying temperatures
Relatively long residence time
Drum provides dispersion as material is conveyed along the length
Benefits of Rotary Drying
Combines flexibility with reliability resulting in a long service life. The rotary is also suitable for operation with a wide range of materials & particle sizes and can more readily accommodate 'upset' up-stream process conditions
Co-current is suitable for materials with relatively high moistures and provides rapid evaporation without overheating the product. Counter-current has the greatest thermal gradient and helps achieve low product moistures
Reduces equipment size and the associated capital and operating costs
Promotes diffusion drying
Relatively low fan power and low headroom
Enables energy savings
