Method for manufacturing cellulose pulp in continuous digester, involves separating free liquid from cellulose tip through top separator, where inlet temperature of free liquid is higher than outlet temperature of free liquid
The method involves separating free liquid from a cellulose tip through a top separator (20). The cellulose tip is arranged on a transfer circuit (11) that is arranged at a top part of a digestion apparatus (30). A collection space is formed on the top separator to collect the free liquid. A guide part is provided with a return line (32). Pressurization recovery of black liquor is performed in the digestion apparatus. Inlet temperature of the free liquid is higher than outlet temperature of the free liquid.
