4·SMALL-SCALE SOLUTIONSAtomizationDifferent atomization modesOne of the most important choices in a plant configuration is choosing the rightatomization and powder discharge method. We offer a wide range of solutions, asillustrated.Rotary atomizerIn rotary atomization, the feed is centrifugally accelerated to high velocity in theatomizer wheel before being discharged into the hot drying gas. The degree ofatomization and particle morphology depends upon peripheral speed, feed rate,liquid properties and atomizer wheel design. Particle size is adjusted by changing theperipheral speed. The rotary atomizer, considered the most flexible atomizing device,is suitable for a wide range of products. Rotary atomizers will generally deliver anarrower particle size distribution and more free flowing powder than two fluid nozzles.Rotary atomizerTwo-fluid nozzle, co-current or fountain modeTwo-fluid nozzle atomization is achieved pneumatically by high-velocity compressedair/gas impacting the liquid feed. Particle size is controlled by varying the nozzle flowratio between atomizing gas and feed. When operating in co-current mode, the nozzletip is placed close to the outlet of the ceiling air disperser. The co-current mode isselected when drying heat-sensitive products. When coarse particles of a non-heatsensitive feed are required, the two-fluid nozzle in fountain mode is appropriate.Co-current nozzlePressure nozzle, co-current or fountain modeWith a pressure nozzle, atomization is the result of the conversion of pressure energywithin the liquid feed into kinetic energy of a moving thin liquid sheet. Pressureapplied to the liquid within the nozzle forces the liquid out of the orifice creating theatomization. A pressure nozzle can be operated in co-current mode or in fountainmode. Particle size is adjusted by changing the feed pressure and nozzle size. Pressurenozzles will generally deliver a narrower particle size distribution and coarser particlesthan other atomizer types.Fountain nozzleCOMBI-NOZZLETM(patented)In some applications, there is a need for both narrow particle size distribution andsmall particle size. GEA has developed the COMBI-NOZZLE , which combines thebest features of pressure nozzles and two-fluid nozzles. As an added benefit, the energyconsumption will typically be less than for a conventional two-fluid nozzle.Please noteFor operation with feeds based on flammable solvents or powders subject to explosionrisk, dedicated designs are available.COMBI-NOZZLE

14·SMALL-SCALE SOLUTIONSFSD and FSD GRANULATOR Multi-stage spray drying technologyThe Fluidized Spray Dryer FSD is an efficient multi-stage dryerwith an integrated fluid bed. It combines spray drying and fluidbed technology in one plant, with the same qualities as a multistage dryer with external fluid beds but with great space saving.Drying and agglomeration take place in a single operation,allowing the production of coarse, dustless and free-flowingparticles. This technology is especially well suited to foodapplications, including sticky, hygroscopic, aromatic and heatsensitive products.Agglomeration improves the dispersability of the powder andconsiderably reduces bulk density.GEA triple-chamber staticfluid bed is mountedbelow the drying chamberThe integrated fluid bed can have up to three sections. Thecenter bed, or agglomeration section, is where the still moistparticles collide to form agglomerates.

SMALL-SCALE SOLUTIONS·17Cleaning solutionsDefine your requirementsCleaning requirements for small-scale dryers can vary from manual toautomatic cleaning. GEA has defined three levels of CIP equipment asstandard options for our small-scale plants: Manual: The chamber is cleaned by manual insertion of a cleaningdevice, as are the cyclone and bag filter. Ducts are dismantled andcleaned by hand. Semi-automatic: CIP nozzles are manually inserted into ducts, and anorbital cleaner with impact jets is manually inserted into the chamber,cyclone and bag filter after manual removal of filter bags. A CIP tank or trolley with circulation pump allows the collection andrecirculation of liquid. Automatic: Pop-up nozzles in ducts and automatically inserted rotatingimpact cleaners in chamber, cyclone and bag filter after manual removalof filter bags. CIP sequencing can be programmed in the control system.GEA tank cleaning equipment ensures efficientcleaning of drying chambers and feed tanks. Thecleaner is driven by the pressure of the CIP liquidand ensures complete cleaning of the entire innersurface (of drying chambers or tanks).Semi-automatic and automatic systems are recommended for larger plant sizes,whereas manual and semi-automatic cleaning systems are more suitable forsmaller designs due to limitations on duct sizes and plant arrangement.A custom-made solution is also available within the described items.When not in use, the retractable CIP nozzle sitsflush with the inner wall. This ensures that it doesnot disrupt operations. The nozzle is pneumaticallyactivated and ensures efficient cleaning (of fluidbeds, ducts, tanks etc.).

Zone 1/21 – An explosive mixture is occasionally presentduring normal operation. Zone 2/22 – An explosive atmosphere is normally not presentand, if it is, it is only for short periods and typically due toplant/operational failures.

This means reducing possible powder emissions and noisefrom process plants. For over a century GEA has been developing componentsand optimized processes to fulfill these requirements. By way of example, powder emission from a spraydryer can be reduced considerably by installing a wetscrubber or bag filter system. To counteract noise from various fans, for example,special noise attenuators can be installed to reducethe noise to an acceptable level.For reducing noisefrom fans, a noiseattenuator is aneffective solution.For removing residual powder,particulates and odor, a speciallydesigned wet scrubber systemcould be the optimal solution.·19
