<p>The invention provides a continuous cooking method, i.e., flow cooking, for pulp, in which method pulp-containing fibrous material is continuously fed into a digester under elevated pressure, characterized in that between the digester proper and the block feeder, a zone, appropriately an absorption zone, is arranged. The zone contains blocking solution that prevents the sulphur dioxide gasified from the cooking zone from entering onto the feeder of the digester and from thereby coming into contact with unabsorbed chips. The invention provides precise control of the variables in the process.</p> |
