摘要 PCT No. PCT/US97/09796 Sec. 371 Date Apr. 1, 1999 Sec. 102(e) Date Apr. 1, 1999 PCT Filed Jun. 5, 1997 PCT Pub. No. WO98/14558 PCT Pub. Date Apr. 9, 1998A 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.
