Flash and Ring Dryers
Corn Gluten Ring Dryer
Pig Manure Ring Dryer
Corn Protein Concentrate Ring Dryer
These are designed for products that dry rapidly,
owing to the easy removal of free moisture, or where
any required diffusion to the surface occurs readily.
Drying applications include: sludges, filter cakes,
slurries, crystals, granules and pastes, in fact, almost
any application requiring a powdered product can be
Flash/Ring dried.
Wet material is introduced into a stream of heated
air where it dries rapidly due to the high rates of heat
and mass transfer, whilst being conveyed through the
drying duct system.
Ring dryers incorporate a centrifugal classifier giving
selective internal recirculation of semi-dried solids
effectively lengthening the retention time of larger
particles in the dryer while finer material, which dries
more rapidly, exits the dryer with the exhaust air.

Fluidised Bed Dryers and Coolers
These are used for the controlled removal
of surface and bound moisture in powder,
crystalline and granular materials. They
work by gently drying or cooling over
extended residence times.
Hot or cold air is passed up through a
perforated distributor plate at a velocity
required to fluidize the material, that is,
to take on the characteristics of a
bubbling liquid.
The gentle but intimate contact of drying/
cooling gas with the product ensures
minimal attrition and dust creation.
Configurations available include:
• Vibrating
• Stirred
• Deep Fluidised Beds
• Embedded Tubes
• Integral drying/cooling
• multiple stages
All as required by product and
application.

Combining flexibility with reliability, this type of
dryer handles a vast range of materials and is suited
to the most arduous conditions.
The design also permits the use of the highest
possible drying temperatures and is not sensitive to
wide variations in material size, moisture content or
throughput.
As the dryer rotates, material cascades through a hot
gas stream, using a series of peripheral flights to lift,
distribute and transport the material. The flights are
designed to suit the particular characteristics of the
material, which may vary with increasing dryness.
Other systems include Direct and Indirect Rotary
Coolers, Direct Fired Rotary Calciners and Indirectly
Heated Rotary Dryers and Calciners for fine and
dusty materials and lower temperature calcining
applications. Partial Gas Recycle Rotary Dryers for DDGS

Superheated Steam Dryer - SSD™
The unique SSD™ drying system is a closed-loop pneumatic dryer, where wet material
is dried in a stream of pressurized superheated steam, rather than air as used in
conventional flash dryers.
Drying in a steam atmosphere eliminates the risk of fire or explosion. The closed
pressurized system ensures no gaseous emissions to the atmosphere.
The conveying steam, at up to 4.0 barg, is indirectly superheated via a shell and tube
heat exchanger, using high/medium pressure steam or hot combustion gases.
The moisture evaporated from the solids creates excess steam, which is continuously
discharged at system pressure.
Up to 90% of the energy used for drying can be easily recovered from the excess
generated steam and used in other processes.

This indirectly heated contact dryer is particularly suitable for processing
hazardous materials and for the evaporation and recovery of solvents in
closed-cycle operation.
Wet material is conveyed into the stationary horizontal drying chamber.
The internal rotating paddles create a thin layer of material along the
jacketed wall of the vessel. Heat is transferred by conduction and moisture
is vaporised. A small counter-current flow of gas is used to carry the
evaporated vapour out of the Rosinaire™.
The paddles are adjustable to set the residence time of the solids within the
vessel, typically from 0.5 to 20 minutes.
The Rosinaire™ can be designed with multiple-zone heat transfer jacket
sections that can use a variety of heating media.

These are designed for drying free-flowing materials such as amorphous or
crystalline powders and granules to very low levels of residual moisture or
volatile content. With long residence times obtainable, columns are
frequently used for diffusion-controlled processes.
The column is designed for plugflow and incorporates a special gas
distribution cone to ensure uniform counter-current gas flow up through
the material.
Residence time can vary from 1 to 24 hours, depending on the required
diffusion rate of moisture through the material.
Column Coolers transfer 90-100% of heat to cooling water flowing through
tubes suspended across the column of slowly moving hot material.
The column is designed as a mass flow vessel giving uniform residence
time and even providing cooling to all the solids.

Vibrating Fluidised Bed Pilot Plant
Rosinaire™ Pilot Plant
Conditioning System Pilot Plant
At GEA Barr-Rosin we have extensive pilot plant facilities,
located in the UK and Canada. This enables comprehensive
testing of clients’ materials on our full range of equipment.
A well-equipped laboratory is also located on each site to
provide rapid analysis of moisture contents, bulk density and
particle size distribution. We use local laboratories for more
specialist analyses.
In addition to the equipment available in our test facilities, some
is available for hire for on-site testing.
Information is available on request.
