Abstract

DENTRO DEL MARCO DE UN NUEVO PROCEDIMIENTO PARA LA PREPARACION DE PARTICULAS Y/O POLVOS, SE PREPARA UNA SUSTANCIA A SER TRATADA O UNA MEZCLA DE SUSTANCIAS EN UN RECIPIENTE PRESURIZADO. SE INTRODUCE UN FLUIDO COMPRESIBLE BAJO PRESION EN LA SUSTANCIA O MEZCLA DE SUSTANCIAS PARA SER DISUELTO Y LA SOLUCION RESULTANTE SE EXPANDE DE MODO QUE SE FORMAN PARTICULAS DURANTE EL PROCESO DE EXPANSION. LAS PARTICULAS FORMADAS SON SEPARADAS A PARTIR DE LA CORRIENTE DE FLUIDO DESCOMPRIMIDO.
