Abstract
PROCEDIMIENTO MEJORADO DE PREPARACION DE PASTA PARA LA FABRICACION DE PAPEL, QUE COMPRENDE LOS PASOS DE: COCER LA PASTA EN UN DIGESTOR CERRADO BAJO TEMPERATURA Y PRESION ELEVADAS; APLICAR UNA PRESION DE FLUIDO EN LA PARTE SUPERIOR DEL DIGESTOR EN EL FINAL DEL PROCEDIMIENTO DE ACCION PARA VACIAR LA PASTA DEL DIGESTOR A TRAVES DE UNA SALIDA DE PASTA; Y ABRIR Y CERRAR CICLICAMENTE LA SALIDA DE LA PASTA, CON LO CUAL SE IMPIDE LA GENERACION DE REMOLINOS INCONVENIENTES DENTRO DEL DIGESTOR. LA APERTURA Y CIERRE CICLICOS DE LA SALIDA DE LA PASTA INCLUYE MANTENER ABIERTA Y CERRADA LA SALIDA POR PERIODO DE TIEMPO IGUALES.
