The solution of a product in a solvent (water) is dehydrated to obtain the product as a powdery solid.
The solution is injected through an atomization nozzle which generates a mist formed of very small droplets.
A very hot air stream makes it possible to evaporate the solvent forming the droplets and to entrain the solid in a cyclone.
This allows the solid particles formed to separate from the drying air which escapes outside the pilot.
The solid is recovered at the foot of the cyclone in a suitable reserve.
