Spray dryer

Spray drying is a process of productivity dry powder from a liquid or a slurry.

The liquid is sprayed in thin droplets in a nozzle and mixed with a hot air flow. It allows to evaporate the water and to generate a fine powder.

The obtained powder is carry to the cyclone who separate the air from the powder. An air filter allowed to retain the most thin particles.
