摘要： A process for preparing low density detergent agglomerates is provided. The process involves the step of: (a) agglomerating a detergent surfactant paste or precursor thereof and dry starting detergent material having a median particle size in a range from about 5 microns to about 70 microns in a first high speed mixer to obtain detergent agglomerates having a median particle size of from about 100 microns to about 250 microns; (b) mixing the detergent agglomerates with a binder in a second high speed mixer to obtain built-up agglomerates having a median particle size in a range of from about 140 microns to about 350 microns; and (c) feeding the built-up agglomerates into a fluid bed dryer in which the built-up agglomerates are agglomerated with another binder and dried to form detergent agglomerates having a median particle size in a range of from about 300 microns to about 700 microns and a density in a range about 300 g/l to about 550 g/l.

摘要： A process for continuously preparing detergent agglomerates comprising the steps of continuously mixing a liquid binder comprising of a mixture of surfactants and a copolymer of epichlorohydrin and a cyclic amine moiety and dry detergent materials into a high speed mixer/densifier to obtain detergent agglomerates. The ratio of the liquid binder to the dry detergent material is from about 1:10 to about 10:1, and the dry detergent materials comprise modified carboxy methyl cellulose. The agglomerates are then optionally mixed in a moderate speed mixer/densifier to further densify them. Finally, the detergent agglomerates are dried so as to increase their density.
