Abstract
EN UN PROCESO DE CRISTALIZACION CONTINUO EN EL QUE SE UTILIZA UN APARATO CRISTALIZADOR DE PANTALLA CON TUBOS DE ASPIRACION (DTB) EVAPORADOR PARA PRODUCIR UN PRODUCTO DE CRISTAL, LA MEJORA CONSISTE EN ALIMENTAR A UNA VELOCIDAD CONSTANTE EN EL CUERPO DE UNA LECHADA UNA SUSPENSION DE CRISTALES EN UNA SOLUCION A UNA TEMPERATURA NO SUPERIOR A LA TEMPERATURA DE TRABAJO DEL RECIPIENTE CRISTALIZADOR DE DTB, EN DONDE DICHA SUSPENSION DE CRISTALES CONTIENE UN SOLUTO Y DE UN 6 A UN 24% EN VOLUMEN, EN BASE AL VOLUMEN TOTAL DE LA SUSPENSION, DE CRISTALES EN DONDE AL MENOS UN 35% DE LOS CRISTALES TIENE UN TAMAÑO SUPERIOR A 14 RETICULOS (1,2 MM), EN UNA CANTIDAD EN QUE EL PESO DE CRISTALES ES DE UN 4 A UN 25 POR CIENTO EL PESO DEL PRODUCTO RETIRADO, CON LO QUE LOS CICLOS DE DISTRIBUCION POR TAMAÑO DE LAS PARTICULAS DEL PRODUCTO RETIRADO SE REDUCE Y AUMENTA LA VELOCIDAD DE PRODUCCION DE CRISTALES DE TAMAÑO GRANULAR.
