Abstract

Procedimiento para la preparación de productos de forma esferoidal, que esencialmente son sólidos a la temperatura del ambiente y tienen un diámetro comprendido entre 1 y 500 micras, caracterizado porque comprende obtener en estado fundido una mezcla homogénea con, por lo menos, otro liquido miscible, que no reacciona en el interior de la mezcla, y que están presentes en relaciones tales que uno de los líquidos, el fundido, formará la fase dispersada mientras que el otro constituirá la fase continua y hacer pasar la mezcla a través de un conducto con una longitud de 500 a 100 veces su diámetro interno, bajo condiciones de flujo turbulento, y enfriado subsiguientemente de la emulsión en la salida del conducto, de modo que se produzca la solidificación de la fase dispersada.
