Spray Dryer

Spray Dryer

A spray dryer 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 vaporized. 

Spray dryers can dry a product very quickly compared to other methods of drying. They also turn a solution (or slurry) into a dried powder in a single step, which simplifies the process and improves profit margins.

How spray dryer is different from other dryers

Spray dryers are useful in encapsulation processes because they quickly and efficiently separate a substance into ultra-fine fragments. As opposed to methods such as freeze drying, pulse combustion drying, and drum drying, spray drying technology is very quick, inexpensive, and easy for a factory to utilize.
