Abstract

PROCESO DE PRODUCCION DE PARTICULAS SOLIDAS MEDIANTE EL SECADO DE DE UN CHORRO PULVERIZADO DE GOTAS DE LIQUIDO. LAS GOTAS SE OBTIENEN LANZANDO UNA FORMULACION LIQUIDA EN FORMA DE UNA PLURALIDAD DE CHORROS (J) (FIGURA 6) DE TAL MODO QUE CADA CHORRO SE DESCOMPONGA EN GOTAS DISTRIBUIDAS DE FORMA APRETADA. ANTES DEL INICIO DE LA COALESCENCIA LAS GOTAS SE EXPONEN AL CONTACTO CON UN FLUJO DE GAS (G) CONFORMADO DE TAL FORMA QUE REDUZCA LA COALESCENCIA MEDIANTE LA RUPTURA DE LA ESTELA DE GOTAS Y/O LA ACELERACION DE LAS GOTAS.
