Abstract
Detergent formulations are granulated commercially by spray drying a slurry of the formulation. There is now proposed a method in which the components in powder form are granulated with a binder in a substantially horizontal annular rotating bed. The binder may be released by the action of the rotating bed.
Claims8
A method of granulating a detergent formulation containing from about 2 to about 40% by weight of detergent active material, and from about 5 to about 60% by weight of detergency builder material to form granules in the range from about 0.3 mm to about 3.00 mm from detergent components in powder form, wherein the detergent components are formed into a substantially horizontal annular rotation bed within an apparatus comprising a roughened rotating table concentrically displaced within a smooth walled cylinder, and contacted with a compatible liquid binder that is released from a component during rotation of the formed bed.
