Abstract

EN EL PROCEDIMIENTO PARA LA AGLOMERACION DE SUSTANCIAS DIFICILMENTE SOLUBLES Y SENSIBLES A LA HIDROLISIS SE HACE PASAR EL POLVO DE LA SUSTANCIA DIFICILMENTE SOLUBLE JUNTO CON AL MENOS UN AGLUTINANTE HIDROSOLUBLE EN CAIDA LIBRE POR UNA ATMOSFERA DE VAPOR DE AGUA A UNA TEMPERATURA DE ENTRE 85 (GRADOS) C Y 105 (GRADOS) C BASICAMENTE SIN INFLUENCIA DE FUERZAS COMPACTADORAS. EL TIEMPO DE PERMANENCIA EN LA ATMOSFERA DE VAPOR DE AGUA ES DE ENTRE 0,5 Y 10 SEGUNDOS APROXIMADAMENTE. A CONTINUACION, LOS AGLOMERADOS FORMADOS SE SECAN EN CAIDA LIBRE, DE TAL MANERA QUE EN LOS PUNTOS DE CONTACTO ENTRE LAS PARTICULAS PRIMARIAS PROCEDENTES DE LOS PUENTES DE LIQUIDO-AGLUTINANTE FORMADOS SE FORMAN UNOS PEQUEÑOS PUENTES DE SOLIDO. EN UN SECADOR DE LECHO FLUIDIZADO INTEGRADO A CONTINUACION TIENE LUGAR EL SECADO FINAL HASTA QUE EL CONTENIDO DE AGUA SEA INFERIOR A UN 0,5 % EN PESO. EL PROCEDIMIENTO SE REALIZA EN UN AGLOMERADOR DE CHORRO DE VAPOR EN EL QUE UN VELO DE PRODUCTO QUE CAE LIBREMENTE PROCEDENTE DE LA MEZCLA PULVERULENTA A AGLOMERAR ES CARGADO CON VAPOR DE AGUA PROCEDENTE DE UNOS INYECTORES DE CHORRO DE VAPOR (5,6). EN LA PARTE INFERIOR DEL AGLOMERADOR (1) HAY CONECTADO UN SECADOR DE LECHO FLUIDIZADO (2) DE MANERA QUE LAS PARTICULAS AGLOMERADAS (4) CAEN DIRECTAMENTE EN EL LECHO FLUIDIZADO.
