A spray dryer is a device used in spray drying. It 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 vaporised. Solids form as moisture quickly leaves the droplets.

Drum drying requires less space and is more economical than spray dryers for small volumes. The ratio of steam consumption to water evaporation is from 1.2 to 1.6:1. The major disadvantages are that the product may have a scorched flavour, and solubility is much lower (85%) because of protein denaturation.

For the drying of liquids or liquid suspensions, the evaporator of choice is usually either a drum dryer or a spray dryer. A typical film drum dryer with a 4 ft. (1.2 m) by 10 ft. (3 m) long drum will evaporate about 600 lb./h (270 kg/h) of water. A typical spray dryer as shown in Figure 5 will evaporate 22,000 lb./h (10,000 kg/h). Where tonnage
