Spray drying is a means of producing a dried powder from a liquid or thick, semi-solid solution by rapidly drying with a hot gas. This is a common method used to dry many temperature-sensitive materials like foods, chemicals and pharmaceuticals. Spraying Systems Co. developed the first line of commercially available nozzles for spray drying in the 1940’s. The term “SprayDry®” was first used by Spraying Systems Co. in 1943 and became a registered trademark of the company in 1951. As demand for products like dried milk and eggs increased during World War II and after, our SprayDry® line evolved rapidly to accomodate a wide variety of applications. Spraying Systems Co. offers the broadest selection of Spray Drying nozzles available, each with multiple configuration options and hundreds of interchangeable components to ensure you get the exact drop size you need.
