The functional principle is basically the same as with normal spray dryers. There are just different technologies that are used to do similar things.
The drying gas enters the system via the heater. A new kind of heater system allows for laminar air flow. The spray head sprays the fine droplets with a narrow size distribution into the drying chamber. The droplets dry and become solid particles. The solid particles are separated in the electrostatic particle collector. The [exhaust gas] is filtered and sent to a fume hood or the environment. The inlet temperature is controlled by a temperature sensor. and can be very dangerous also due to particulate matter
