Abstract
LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO Y A UN APARATO PARA LA FABRICACION CONTINUA O POR LOTES SUCESIVOS DE MICROCAPSULAS QUE TIENEN UN NUCLEO QUE CONTIENE UN MATERIAL LIQUIDO, GASEOSO, SOLIDO, O EN FASES MULTIPLES QUE ESTA REVESTIDO CON UNA PELICULA IMPERMEABLE. LAS MICROCAPSULAS SE FORMAN APLICANDO UNA PRESION ELEVADA, DURANTE UN BREVE PERIODO DE TIEMPO, A UNA MEZCLA DE LOS MATERIALES DE NUECLEO Y CASCARA, Y REDUCIENDO PROGRESIVAMENTE LA PRESION, POR EJEMPLO, HACIENDO PASAR LAS CAPSULAS A TRAVES DE UNA CAMARA PROVISTA DE DEFLECTORES. LA INVENCION SE REFIERE TAMBIEN A UN METODO PARA AJUSTAR ELA TAMAÑO DE LAS MICROCAPSULAS Y EL ESPESOR DE SUS CASCARAS. LAS CAPSULAS PUEDEN REALIZARSE CON VARIAS CAPAS DE CASCARA PARA AUMENTAR SU RESISTENCIA MECANICA, O BAJO LA FORMA DE CAPSULAS MULTIPLES, QUE TIENEN DOS O MAS NUCLEOS. EL APARATO INCLUYE UN MEDIO PARA ALMACENAR UNA MEZCLA DE MATERIALES DE NUCLEO Y DE CASCARA (33), UNA CAMARA DE COMPRESION (34), UN APARATO DE REDUCCION DE PRESION (36), Y UNA TUBERIA DE RECICLADO OPCIONAL (37). EL APARATO DE REDUCCION DE PRESION (36) PUEDE INCLUIR UNA CAMARA (59) QUE TIENE DEFLECTORES (60) PARA AUMENTAR LA TURBULENCIA. LA INVENCION ES PARTICULARMENTE UTIL PARA PRODUCIR CAPSULAS DE LIBERACION RETARDADA Y PRODUCIR MICROCAPSULAS EN UNA PEQUEÑA FRACCION DEL TIEMPO NECESARIO CON LO SMETODOS DE LA TECNICA ANTERIOR.
