users understand both the benefits and the limitations of the spray drying process. It is also important that users choose the right system based on the requirements of the application. The Spray Drying Process The basic spray drying process consists of three processing steps: Atomization of the feed slurry into tiny droplets. This is accomplished
The basic spray drying process has three essential steps: Atomisation, where the droplets are formed. Drying gas and droplet contact, where the liquid is evaporated. Powder recovery, where the dried particles are separated from the drying gas stream. The spray dryer is a suspended particle dryer.

Spray Dryer A spray dryer is a device used in spray drying. It takes a liquid stream and separates the solute or suspension as a solid and the solvent into a vapor. The solid is usually collected in a drum or cyclone. The liquid input stream is sprayed through a nozzle into a hot vapor stream and vaporised.

Maximum efficiency for drying and granulating. The fluid bed ensures an amazingly fast, gentle and uniform drying. Fluid bed dryers are therefore often used in combination with high shear granulators (wet mixers). With the addition of a spray nozzle, the dryer becomes a granulator. Fluid bed granulations are known for their superior homogeneity.
