Abstract
La presente invencion se refiere a un metodo para producir percarbonato de sodio revestido granular, con un valor TAM bajo. El percarbonato de sodio es producido por granulacion de lecho fluidizado a una temperatura TG en el intervalo desde 45 a 75°C y revestimiento atomizando una solucion acuosa que contiene al menos, un componente de revestimiento en un lecho fluidizado a una temperatura Tu en el intervalo desde 35 a 100°C. De conformidad con la invencion, a) despues de la granulacion de lecho fluido pero antes de revestir una etapa de secado suplementario se lleva a cabo a TNT superior que TG, o b) granulacion de lecho fluido se lleva a cabo al menos dos etapas a TG1, TG2, TGn, con TG2 o TGn siendo mayor que TG1, y sin etapa complementaria de secado requerida si 2/3 de los granulos se han formado a TG1, o c) el secado complementario se lleva a cabo sin granulacion adicional pero solamente despues del revestimiento, es decir, a TUNT, con TUNT siendo al menos, 20°C superior que TG.
