A spray dryer is a food processing equipment that uses hot gas to produce a dry powder after rapidly drying a liquid or slurry. The spray dryer works by separating the solute or suspension particles as a solid and the solvent as vapor.  It has a spray nozzle that disperses the liquid into a controlled drop size spray. It is used to produce dry solids and form powdery substances or granules usually applied in pharmaceutical products, beverages, food, and plant extracts. This spray dryer is found in the CALABARZON Food Solutions Hub or C-FoSH at the Laguna State Polytechnic University in Sta. Cruz, Laguna provided by the Department of Science and Technology (Text & Photo by Rodolfo P. de Guzman/S&T Media Service)
