Abstract

Procedimiento de granulación en lecho fluido que comprende las etapas de: - formación de un lecho fluido de semillas (Si) de una sustancia escogida, - suministro de dicho lecho fluido con un flujo de fluido continuo (L) que comprende un líquido de crecimiento, - inducción y mantenimiento de un vórtice continuo (V) en dicho lecho fluido, teniendo el vórtice (V) un eje sustancialmente horizontal, caracterizado porque dicho flujo fluido (L) se suministra en primeras zonas predeterminadas (Z1) de dicho lecho fluido, alternandose dichas primeras zonas (Zi) con segundas zonas (Z2) de dicho lecho fluido en las que no se suministra dicho flujo fluido (L). Siguen 3 hojas de dibujos numeradas correlativamente.
