Patent

CA 2268067

A non-tower process for continuously preparing granular detergent composition having a density of at least of 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, in a mixer, wherein first agglomerates are formed and (b) granulating the first agglomerates in one or more fluidizing apparatus.

Cette invention se rapporte à un procédé n'utilisant pas de tour, qui sert 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, dans un mélangeur, de façon à former un premier type d'agglomérats; et (b) à réduire ces premiers agglomérats en granulés dans un ou plusieurs appareils de fluidisation.
