A pulp lifter mounted to a discharge end wall including an elongate body portion rotatable successively between a discharge condition, in which an outer end is raised above an inner end of the body portion to cause pulp in a pulp chamber associated with the pulp lifter that includes the body portion to flow toward a central hole in the discharge end wall under the influence of gravity, and a non-discharge condition, in which the pulp in the pulp chamber associated with the pulp lifter including the body portion is not flowable toward the central hole under the influence of gravity. A transverse portion is provided for receiving at least a part of a carryover portion of the pulp that remains in the pulp chamber associated with the pulp lifter when the body portion of the pulp lifter is moved to the non-discharge condition thereof. |
