Abstract
A method of manufacturing granular detergents containing 15-40% of surface active agent, 5-20% of sodium silicate and 0.5-5% of aluminosilicate on a dry weight basis, which comprises subjecting a detergent slurry and an aluminosilicate slurry to spray-drying separately within the same drying space. The granular detergent thus manufactured possesses improved fluidity as well as reduced degree of hygrocaking property and compression-caking property. Incorporation in the aluminosilicate slurry with a small amount of an inflating agent will provide a granular detergent which is further improved in fluidity, hygrocaking property and compression-caking property.
