Flash and Ring Dryers 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.

Rotary Dryers, Coolers and Calciners 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™
SSD™ Ring Dryer
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.

Rosinaire™ Paddle Dryer 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.

Column Dryers and Coolers 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.

Pilot Plant Comprehensive testing of client’s materials
Vibrating Fluidised Bed Pilot Plant
Rotary Pilot Plant Dryer
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.
