Drum dryer isused for drying out liquids
from raw materials with drying drum. In the drum-drying process,
pureed raw ingredients are dried at relatively low temperatures
over rotating, high-capacity drums that produce sheets of
drum-dried product. The drum dryer is suitable for fuel plant,
fertilizer plant, chemical plant, pharmaceutical and other
industries.

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 DryingRobust constructionPermits

provides dispersion as material is conveyed along the

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 conditionsCo-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 moisturesReduces
