spray-drying
Droplet dehydration method
Spray-drying is an industrial process that converts liquid into powder by spraying it into a hot chamber where the moisture evaporates almost instantly.
The technique produces milk powder, instant coffee, detergents, and pharmaceuticals.
The resulting particles are uniform and free-flowing: Spray-drying preserves the flavor compounds better than other methods.
