A process for the production of granular detergent compositions is provided wherein fluid bed granulation is em- ployed in conjunction with selected recycle of oversized particles to control the uniformity of the resulting detergent composition. The process comprises feeding starting ingredients into a fluid bed granulator to at least partially granulate the feed material while employing the fluid bed to control undersized particle generation and sizing in conjunction with recycle to control oversized particles.
La présente invention concerne un procédé de production de compositions de détergent granulaire dans lequel on utilise une granulation en lit fluidisé simultanément avec un recyclage sélectif de particules de tailles irrégulières afin de régler l'uniformité de la composition détergente finale. Ce procédé consiste à alimenter un granulateur à lit fluidisé en ingrédients de départ, à granuler au moins partiellement le matériau en utilisant le lit fluidisé afin de réguler la production de particules sous mesure et à les mettre à la mesure, en recyclant simultanément, afin de réguler les particules hors mesure.
