Abstract

The invention relates to a method for producing free-flowing, dustless keto-L-gulonic acid granules from fine-particle, pure keto-L-gulonic acid. According to said method, an aqueous or water-containing solution of keto-L-gulonic acid is supplied to a) a spray fluidised bed drying installation, b) a single-substance nozzle atomisation drying installation, or c) a disk atomisation drying installation.
