A process for preparation of a granular detergent composition which process comprises the steps of (i) forming a liquid feedstock comprising a liquid binder and a structurant; (ii) dosing the liquid feedstock and a solid component into a high-speed mixer/densifier, to form a granular detergent material and forming or introducing further structurant in the high-speed mixer/densifier; (iii) subsequently treating the granular detergent material in a moderate-speed granulator/densifier, whereby it is brought into or maintained in a deformable state; and (iv) drying and/or cooling the product of step (iii).

Ce procédé de préparation d'une composition détergente granulaire comprend les étapes consistant: (a) à former une charge d'alimentation liquide comprenant un liant liquide et un agent de structuration, (b) à doser la charge d'alimentation liquide et un constituant solide dans un mélangeur/densificateur tournant à grande vitesse, afin de former une matière détergente granulaire, puis à former ou à introduire une autre agent de structuration dans le mélangeur/densificateur tournant à grande vitesse, (c) ensuite à traiter la matière détergente granulaire dans un granulateur/densificateur tournant à vitesse modérée, ce qui permet de mettre ou de maintenir cette matière dans un état déformable, et (d) à sécher/et ou refroidir le produit de l'étape (c).
