The working principle of the LPG Centrifugal Spray Dryer is based on a liquid feed that gets converted into dried particles through some controlled steps. The primary components of the spray dryer are a drying chamber, atomization system, hot air generator, and cyclone separator.

Atomization: The atomization system has liquid feedstock pumped into it in the form of solutions or slurries. Here; the liquid is converted to fine droplets by using different techniques such as pressure nozzles, rotary atomizers, and centrifugal atomizers with then the intention of making the liquid go evenly throughout the drying chamber

Drying Chamber: In the drying chamber, where hot air comes into contact with atomized droplets. This hot air evaporates moisture from droplets and removes moisture-laden air out of it.

Evaporation and Drying: In this process heat energy from hot air causes the moisture within the droplet to rapidly evaporate as they travel through the drying chamber. This leads to dried particle formation that falls inside the chamber.

Separation and Collection: A cyclone separator or other filtration systems are used to store these dry particles from hot air. The collected particles can be subjected to further processing or packaging depending on specific application needs.
