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.

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.
