Spray drying is a single-step drying technique that has been used in several different industrial applications, such as food, dairy, detergents, and pharmaceuticals. It was originally invented by Percy (1872) and was widely used for converting milk to dry powder during World War II.
Since in spray drying processes there is a need to maximize the solids concentration to optimize the process throughput (in most applications concentrations are at least 10% w/w) it can be stated that the solids concentration has often little impact on the final particle size of the spray dried powder.
Spray drying is a method of producing a dry powder from a liquid or slurry by rapid drying with a hot gas. This is the preferred method of drying for many thermally sensitive materials. All spray dryers use some type of atomizer or spray nozzle to disperse the liquid, or slurry, into a controlled drop-size spray. The most common of these are rotary …
