Spray drying is a processing technology to transform a liquid feedstock into a dried powder through four fundamental steps: Atomization of the feed into a spray, spray gas contact, solvent evaporation and separation of the dried product from the drying medium. The S-300 Buchi Spray Dryer has an evaporation capacity of 1.0 L / h H2O, higher for organic solvents, the final particle size is 1 – 60 μm and yields up to 70%.
