Choosing the Right Dryer for Your Sugar Processing Operation
Industrial Rotary Dryer play an important role in sugar processing
operations. When faced with the decision of what type of drying
system to employ, facility operators generally have two options to
choose from: Rotary Dryer or fluid bed. Here are some of the most
notable pros and cons associated with each type of system.
One of the biggest benefits of rotary dryer is that they have the
ability to accept particles of different sizes, wetness, and mass.
As a result, they are ideal for use in applications where there’s a
great deal of variance in the quality of raw feedstock. Fluid bed
dryers, on the other hand, typically require a higher level of
uniformity in feedstock composition in order to be effective –
making them more sensitive to changing and/or inconsistent process
conditions.
Sugar Rotary Dryer Maintains
While both types of drying systems require some degree of
maintenance in order to remain operable, rotary dryer generally
have more extensive requirements because they consist of a higher
number of moving parts. This is in contrast to fluid bed systems,
which are made up of fewer mechanical components and work by moving
hot air through a fluidized particle stream perpendicular to its
direction of travel.
Sugar Rotary Dryer and Fluidizing Power Use
Fluidizing solid materials requires energy, and because of this,
fluid bed dryers typically consume more power. This is especially
true in the case of feedstock with large and/or heavy particles.
Generally speaking, rotary dryers are more energy efficient, making
them better suited for high-capacity processing applications.
Sugar Rotary Dryer Features:
Reduced air rates for the processes drying and cooling
Exhaust air from cooling system used for drying, without any
additional dust dedusting equipment
Thermal energy savings
Sugar exposed to low temperature loads in the drying process
Thermal / mechanical interaction on the crystal surface for optimum
drying in the drum dryer
Large drum volume helps produce uniform flow rates for all
downstream equipment
Sugar lumps or short periods of elevated sugar moisture are
tolerated without any problems
A central pipe can be installed for improved drying efficiency
Effective cooling in the fluidized bed
Adjustment of constant sugar outlet temperatures throughout 24-hour
periods in systems of adequate capacity
Compact plant design
Separation of dust particles from sugar stream
The Bottom Line
The choice of which type of drying system to use in a sugar
processing operation will ultimately be dictated by the goals of
the operator and the unique requirements the facility itself. In
every case, buyers should collaborate closely with their equipment
supplier and installer to ensure that individual needs with regards
to maintenance, energy consumption, and reliability are properly
addressed.
