Spray Dryer Key Components
What is a spray dryer? As we can see from the name, it is a device that uses spray for drying. A spray dryer mixes a heated gas with a stream of atomised (sprayed) liquid in a vessel (drying chamber) to accomplish evaporation and produce a free-flowing dry powder with a controlled average particle size.
Spray dryer operation includes the following key components:
*A device to atomise the solution or slurry
*Air/gas heater or source of hot air, e.g. exhaust gas
*Gas/mist mixing chamber with sufficient residence time and droplet trajectory distance for heat and mass transfer
*Apparatus for recovering solids from the gas stream
*Fans to direct the required air/gas through the spray drying system
