Abstract

L'invention concerne un procédé permettant de préparer des agglomérats détergents d'une faible densité comprise environ entre 300 g/l et 550 g/l. Ce procédé consiste à (a) agglomérer une pâte tensioactive détergente ou un précurseur de cette pâte et à sécher cette matière détergente de départ dans un premier mélangeur ultra-rapide pour obtenir des agglomérats initiaux; (b) à mélanger les agglomérats initiaux dans un second mélangeur ultra-rapide pour obtenir des agglomérats intermédiaires; et (c) à acheminer ces agglomérats intermédiaires vers un séchoir à lit fluide dans lequel un liant est pulvérisé par une buse située à une hauteur d'environ 25 cm à environ 60 cm à partir de la plaque distributeur du séchoir à lit fluide de telle façon que les agglomérats intermédiaires soient séchés et agglomérés pour former les agglomérats finaux faiblement détergents souhaités.
