In the periodic cooking of lignocellulosic material in a digester, the homogeneity of the digester contents can be improved by the interposition of at least one surge-boil during the cooking process which is effected by reducing the pressure in the digester together with the direct introduction of steam into the bottom of the digester, simultaneous with pressure reduction, at a rate of at least 0.1 ton steam/minute. |
