A non-tower process for continuously preparing granular detergent composition having a density of at least about 600 g/1 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) granulating the agglomerates in one or more fluidizing apparatus.
Cette invention se rapporte à un procédé n'utilisant pas de tour et servant à préparer en continu une composition détergente granulaire ayant une densité d'au moins 600 g/l environ. Ce procédé consiste: (a) à disperser un tensioactif et à revêtir ce tensioactif d'une fine poudre ayant un diamètre compris entre 0,1 et 500 microns, tout en mouillant le tensioactif revêtu de cette fine poudre avec un liquide finement atomisé dans un mélangeur, et (b) à réduire ces agglomérats en granulés dans un ou plusieurs appareils de fluidisation.
