Abstract
A method for improving the homogeneity of ligno-cellulose containing materials during digestion in a digester is disclosed. Specifically, the ligno-cellulose containing material and cooking liquor are charged to the digester, a portion of the cooking liquor is drawn off from the digester and heated, preferably in a calorisator, and the heated liquor is divided into two portions, the first portion being returned to the top of the digester, and the second portion being returned to the bottom of the digester, and boiling is caused to occur in the digester solely by terminating the flow of liquor into the top of the digester.
