Abstract

Un método para pulpear papel de desperdicio incluye proporcionar un recipiente de pulpeo con un rotor y al menos un sensor de flujo para medir el flujo de la suspensión dentro del recipiente de pulpeo. El recipiente de pulpeo se carga con una suspensión (papel de desperdicio y agua), las cantidades de papel de desperdicio y agua son tales que la suspensión tiene una consistencia en el rango de 10 % a 30 %. La carga de papel de desperdicio en el recipiente de pulpeo se pulpea a un nivel de energía preseleccionado mientras se monitorea el flujo de la suspensión poloidal; puede añadirse agua cuando el flujo poloidal cae por debajo de un valor de flujo umbral inferior predeterminado para reducir la viscosidad y restablecer el flujo poloidal dentro del recipiente de pulpeo. La velocimetría Doppler es un método preferido para monitorear el flujo de la pulpa. En una construcción particularmente preferida el rotor tiene una unidad de energía variable. El método de la invención es especialmente útil para elaborar pastas de papel de alta calidad y alto brillo a partir de papel de desperdicio que varía entre un lote y otro.
