    摘要： A process for producing a low density detergent composition is provided. The process involves: (a) agglomerating a detergent surfactant paste or precursor thereof and dry starting detergent material in a frist high speed mixer to obtain detergent agglomerates; (b) mixing the detergent agglomerates in a second high speed mixer to obtain built-up agglomerates; and (c) feeding the built-up agglomerates and a binder into a fluid bed dryer to form detergent agglomerates having a density in a range from about 300 g/l to about 550 g/l, the fluid bed dryer being operated at a Stokes Number of less than about 1, wherein Stokes Number = 8ςξd/9ν, ς is the apparent particle density of the built-up agglomerates, $(g)n is the excess velocity of the built-up agglomerates, d is the mean particle diameter of the built-up agglomerates and ν is the viscosity of the binder.

    摘要： 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 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 can also comprise further step (b'), i.e., thoroughly mixing the second agglomerates in a mixer, between step (b) and step (c).
