Abstract

UN LIQUIDO ACEITOSO Y UN LIQUIDO ACUOSO SEGUN SE HAN PREPARADO A UNA TEMPERATURA DE 80 (GRADOS) C SE EMULSIFICAN DE FORMA CONTINUA A UNA TEMPERATURA DE 50 (GRADOS) C O MAYOR PARA PRODUCIR UNA EMULSION, ENTONCES EL LIQUIDO QUE COMPRENDE UN POLIAMINO Y AGUA PARA EL AJUSTE DE LA CONCENTRACION A UNA TEMPERATURA DE 50 (GRADOS) C O MAYOR SE AÑADE A LA EMULSION Y SE MEZCLA EN UN MEZCLADOR ESTATICO, LA MEZCLA DE LA EMULSION SE HACE FLUIR DE FORMA CONTINUA AL INTERIOR DE UN DISPOSITIVO DE ENCAPSULACION DESDE EL FONDO HASTA LA PARTE SUPERIOR DEL MISMO, Y SE OBTIENEN MICROCAPSULAS POR DESBORDAMIENTO DESPUES DE UN TIEMPO DE RETENCION DE 60 MINUTOS APROXIMADAMENTE.
