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.

High Temperature Fluidised Bed for Potash

Fluidised Bed Dryers and CoolersThese 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.

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.

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.
