How does spray dryer work? - Lab Instrument Manufacturer

A spray dryer takes a liquid stream and separates the solute or suspension as a solid and the solvent into a vapor. The solid is usually collected in a drum or cyclone. The liquid input stream is sprayed through a nozzle into a hot vapor stream and vaporized. Solids form as moisture quickly leaves the droplets.

Spray Dryer Atomization Spray Drying.

A spray is created by contacting two fluids, the feed and a compressed gas. The atomization energy is provided by the compressed gas, usually air. The contact can be internal or external to the nozzle. A broader particle size distribution is generated. The average particle size produced for a given spray dryer feed is primarily a function of ...

There are four fundamental steps involved in spray drying (Broadhead et al., 1992; Filkova et al., 2006): (1) Atomization of a liquid feed into fine droplets, (2) Droplet-hot air contact (3) Evaporation of droplet water and (4) Recovery of the powder. In addition, the feedstock is normally concentrated prior to introduction into the spray dryer.
