Abstract:
A non-tower process for continuously preparing granular detergent composition having a density of at least about 600 g/l is provided. The process comprises the overall steps of: (a) dispersing a surfactant, and coating the surfactant with fine powder in a mixer, wherein first agglomerates are formed; (b) spraying finely atomized liquid onto the first agglomerates in a mixer, wherein second agglomerates are formed; and (c) granulating the third agglomerates in one or more fluidizing apparatus. The process is improved by further step (b'), by thoroughly mixing the second agglomerates in a mixer, between step (b) and step (c), wherein, in step (b'), choppers are used to reduce the amount of oversized agglomerates.

Abstract:
A non-tower process for continuously preparing a granular detergent composition having a density of at least about 600 g/l is provided. The process comprises the steps of: (a) dispersing a surfactant, and coating the surfactant with fine powder having a diameter from 0.1 to 500 microns, while wetting the surfactant coated with the fine powder with finely atomized liquid, in a mixer, and (b) thoroughly mixing the agglomerates in a mixer. Step (b) can also be followed by further step (c), i.e., granulating the agglomerates from step (b) in one or more fluidizing apparatus, during which further coating can be used to prevent over-agglomeration.
Abstract:
A process for preparing a low density detergent composition is disclosed. The process includes the steps of agglomerating a detergent surfactant paste and dry starting detergent material in a high speed mixer to obtain detergent agglomerates wherein the detergent agglomerates include at least 3% by weight water and dielectrically heating the detergent agglomerates so as to form the detergent composition having a density of below 600 g/l.
