Abstract

QUE COMPRENDE: A) UNA CAJA QUE TIENE UNA ENTRADA PARA UN GAS, UNA SALIDA Y UNA CAMARA ADECUADA PARA CONTENER UN MATERIAL EN PARTICULAS; B) UN FLUIDIZADOR DE PARTICULAS QUE PROVEE UNA CIRCULACION FLUIDIZADA DEL MATERIAL EN PARTICULAS CON EL GAS, EN DICHA CAMARA, AL PONER EN FUNCIONAMIENTO EL DISPOSITIVO; Y, C) UN CLASIFICADOR DE PARTICULAS EN COMUNICACION POR FLUIDO CON LA CIRCULACION FLUIDIZADA ENTRE LA CAMARA Y LA SALIDA. DONDE, (B) CAUSA UNA CIRCULACION DE TORBELLINO DEL MATERIAL EN PARTICULAS FLUIDIZADO GENERANDO: a) UNA REGION CENTRAL DE BAJA PRESION DENTRO DE LA CAMARA EN COMUNICACION POR FLUIDO CON LA ENTRADA, DE MODO QUE EL GAS CIRCULA DENTRO DE LA CAMARA; b) UNA REGION EXTERIOR DE ALTA PRESION DENTRO DE LA CAMARA EN COMUNICACION POR FLUIDO CON LA SALIDA, DE MODO QUE EL GAS CIRCULA DESDE DICHA REGION EXTERIOR HASTA LA SALIDA; Y (C) PERMITE QUE PARTICULAS DENTRO DEL MATERIAL CON UN TAMANO INFERIOR O IGUAL AL TAMANO E INERCIA PREDETERMINADOS SE DESVIEN DE LA CIRCULACION DE TORBELLINO Y SALGAN DE LA CAMARA; Y, ASIMISMO EXCLUYE QUE PARTICULAS DENTRO DEL MATERIAL, CON TAMANO SUPERIOR AL TAMANO E INERCIA PREDETERMINADO, SALGAN DE DICHA CAMARA. SE REFIERE TAMBIEN A UN METODO PARA DISPENSAR UN MATERIAL EN PARTICULAS AEROSOLIZADO PARA INHALACION
