PROCESS FOR PREPARING A HIGH BULK DENSITY GRANULAR DETERGENT COMPOSITION

PROCESS FOR PREPARING A HIGH BULK DENSITY GRANULAR DETERGENT COMPOSITION

A granular detergent composition or component having a bulk density of at least 650 g/l can be prepared by treating a particulate starting material (i) in a first step in a high-speed mixer/ densifier, the mean residence time being from about 5-30 seconds; (ii) in a second step in a moderate-speed g...

Zusammenfassung:A granular detergent composition or component having a bulk density of at least 650 g/l can be prepared by treating a particulate starting material (i) in a first step in a high-speed mixer/ densifier, the mean residence time being from about 5-30 seconds; (ii) in a second step in a moderate-speed granulator/densifier, whereby it is brought into, or maintained in, a deformable state, the mean residence time being from about 1-10 minutes and (iii) in a final step in drying and/or cooling apparatus. Preferably, the deformable state is induced in the first step.
