May 23, 2018· Engineering. The objective of this experiment is to study spray dryers and spray drying operation. In industry, spray drying is used to separate liquid from solid. In a spray dryer, a liquid solution is dispersed into a stream of hot gas in the form of a mist of fine droplets. Moisture is rapidly vaporized from droplets and leaves residue
Drying is taking place thanks to dry air contacting the sprayed droplets. The air ability to take up moisture , and thus dry the particles is increased by heating up the air prior it enters the spray drying chaer. It has a low relative humidity at inlet and a high relative humidity, lower temperature at the exit.
