Abstract

Un procedimiento para la produccion de partículas detergentes comprende la introduccion de un precursor ácido de un tensioactivo anionico y agente neutralizante en una evaporadora/secadora de película delgada horizontal que comprende una region de mezclado, una region de secado y una region de enfriamiento. Las partículas de detergente resultantes se clasifican para separar una fraccion de gránulo sobredimensionada donde al menos el 70% en peso de las partículas tiene un diámetro mínimo de 1000 micrones. Esta fraccion se vuelve a introducir en el proceso.
