Abstract

PROCEDIMIENTO Y APARATO PARA PRODUCIR PULPA CELULOSICA POR EL METODO DE PULPACION TERMOMECANICA. EL PROCEDIMIENTO CONSISTE EN PONER ASTILLAS DE MADERA EN CONTACTO CON VAPOR DURANTE UN TIEMPO SUFICIENTE COMO PARA CALENTARLAS A LA TEMPERATURA DEL VAPOR, Y COMPACTARLAS, DESPUES, MIENTRAS SE TRANSPORTAN PARA SU DESHUMIDIFICACION. LA MASA COMPACTA RESULTANTE SE DESMENUZA Y SE INTRODUCE EN UN REFINADOR. EL APARATO CONSTA DE UN DEPOSITO (10) DE ASTILLAS CON UN DISTRIBUIDOR DE VAPOR (11), DE UN TRANSPORTADOR DE TORNILLO SIN FIN (15) ACCIONADO POR UN MOTOR (16); DE UN SEPARADOR DE VAPOR (17) Y DE OTRO TRANSPORTADOR (18).
