Depending on the material being dried, spray dryers can use heated air or heated inert gasses; when combustible materials must be dried, gasses like nitrogen are used to minimize reaction risks.

Spray dryers are industrial drying systems that combine the processes of atomization and heating to dry a material. Atomization is the process by which a material is dispersed into extremely fine droplets. In spray drying, a material that is intended to be dried is mixed with a liquid and forced at high speeds into a chamber by a nozzle. Heat is then forced into the chamber, causing the liquid to evaporate and leaving behind fine solid particles.

The spray drying process begins with collections of materials to be dried and a solvent (which is often water). When the solute and solvent are mixed, the sludge or slurry created by this mixing are spun centrifugally and then forced through an atomizing nozzle at high speeds. While suspended in the drying chamber into which the material has been injected, it is exposed to a heated gas.

The solvent falls to the bottom of the chambers as the liquid solvent vaporizes. The dried materials are collected and prepared for the next phase of processing. The evaporation rate and the necessary size distribution of a product determine how much air is needed, which then affects the size and cost of most system components. As a result, these are the most important factors when designing a spray dryer.

Spray drying is often used when the product must meet exact requirements in terms of particle size distribution, particle shape, bulk density, and residual moisture content. Advantages of spray drying over other industrial drying processes include particle size control, enhancing flow properties of dry solids, evaporative cooling, corrosion reduction and short residence.
