Abstract

Procédé de production de granulés de sel d'acide polyacrylique facilement solubles dans l'eau. Le procédé consiste à granuler une poudre soluble dans l'eau du sel d'acide polyacrylique selon une méthode de granulation à lit fluidisé, tandis qu'une solution aqueuse d'un sel d'acide polyacrylique ayant une viscosité de 50-700 cps y est pulvérisée. Ces granulés peuvent être utilisés comme additifs alimentaires ou médicaments.
