Abstract
Un procedimiento para la preparación de percarbonato de sodio recubierto en forma de granulado, que posee un bajo valor de TAM. La preparación se lleva a cabo mediante granulación por rociado en lecho fluidizado a una temperatura TG en el orden de 45 a 75°C, el recubrimiento mediante rociado de una solución acuosa que contiene por lo menos un componente de recubrimiento en un lecho fluidizado a una temperatura TU en el orden de 35 a 100°C: De acuerdo con la invención a) después de la granulación por rociado en lecho fluidizado pero antes del recubrimiento se lleva a cabo un post-secado a TNT mayor que TG, o b) la granulación en lecho fluidizado se realiza por lo menos en dos etapas a TG1, TG2... TGn, siendo TG2 o bien, según corresponda, TGn mayores que TG1, siendo superfluo un post secado, cuando 2/3 del granulado ha sido formado a TG1, o c) no se realiza el post-secado después de la granulación sino recién después del recubrimiento y específicamente a TUNT, siendo TUNT por lo menos 20°C mayor que TG.
