For more than 50 years spray drying has been successfully employed in a vast number of scientific andor industrial applications as a simple efficient reliable and scalable technique to convert aqueous or organic solutions emulsions dispersions and suspensions for convenience all will be referred to as liquidspray solutions for the rest of this article into a dry powder.
For the process different nozzle systems can be employed and the one selected will depend on the requirements of the userFor example at an industrial level a rotary disc nozzle is mainly employed while for laboratory scale research and pilot scale production a 2Fluid nozzle is commonly used1.

Micheal Whelehan Philipp John and Nurhan T Dunford examine the production of coreshell microcapsules by spray drying using a 3Fluid nozzle in a single step process.
Narrower particle size distribution and more free flowing powder than two fluid nozzlesTwofluid nozzle cocurrent or fountain mode Twofluid nozzle atomization is achieved pneumatically by highvelocity compressed airgas impacting the liquid feedParticle size is controlled by varying the nozzle flow ratio between atomizing gas and feed.
The FSD174 Spray Dryer combining spray and fluidbed drying is designed to provide optimum drying efficiency and the best product quality in agglomerated powdersThe design specific to the different industries has gained worldwide recognition among producers of a wide range of food products and chemical compounds.
The Mini Spray Dryer has a integrated twofluid nozzle Compressed gas normally air or N2 is used to disperse the liquid body into fine droplets which are subsequently dried in the cylinderConnection for cooling water 5Connection for compressed spray gas 6.
This approach has been very successful and enabled the encapsulation of thousands of different products from pharmaceuticals bioactives essential oils aroma compounds and food additives providing the encapsulated material with a myriad of benefits4.
To overcome the above problems BÜCHI Labortechnik AG has developed a 3Fluid nozzle system for their spray drying technology156 which allows encapsulation of a product within coreshell microcapsules Fig2 displays the structural differences between a matrix and coreshell microcapsule in a single step process.

Twofluid nozzle atomization by kinetic energy Rotary atomizers Atomization by centrifugal energyWide ranges of spray dryer designs are available to meet various product specificationsIt has few moving parts and careful selection of various components can result in a system having no moving parts in direct contact with the product.
Typically a spray drying nozzle will produce droplets as small as 12 micron and as large as 400500 micronHowever the majority will be within a range of 50 200 micronThe narrower the range of droplet size the more suited it is to spray drying with a ‘mono range’ the ultimate goal for most operators.
