Abstract

A process for preparing low density detergent agglomerates having a density in a range from about 300 g/l to about 550 g/l is provided. The process involves the steps of: (a) agglomerating a detergent surfactant paste or precursor thereof and dry starting detergent material in a first high speed mixer to obtain agglomerates; (b) mixing the agglomerates in a second high speed mixer to obtain built-up agglomerates; and (c) feeding the built-up agglomerates into a fluid bed dryer in which a binder is sprayed via a nozzle having a height of from about 25 cm to about 60 cm from the distributor plate of the fluid bed dryer such that the built-up agglomerate are dried and agglomerated to form the desired low detergent agglomerates.
