Abstract
A process for preparing coated detergent granules in a fluidized bed is provided. The fluidized bed is operated at a flux number of at least about 3.5 and/or a Stokes Number of greater than 1.0. Upon drying, the resultant detergent particles have improved appearance and flow properties and may be packaged and sold as a detergent material or mixed with various other detergent ingredients to provide a fully formulated detergent composition.
