摘要： A device for discharging particulate material from a container with a table to support the particulate material includes a feed unit which is movable on the table for discharging the material through a peripheral outlet opening, and a drive for driving the feed unit; the feed unit includes at least two spaced feeding elements disposed to successively move the material in a direction from the center of the table towards the outlet opening; the feeding elements are arranged, during a full cycle of movement of the feed unit, to be alternately active within an arbitrary section of the table extending between the center part and outlet opening for feeding a layer of particulate material in front of them in the direction toward the outlet opening and inactive while returning to a starting position.

摘要： The present invention relates to a method for continuous cooking of kraft pulp in a single-vessel system (1), preferably a single-vessel hydraulic digester, with chips being conveyed from a high-pressure feeder (2) in a transfer line (2A, 4A) to a first end (3) of the digester (1), the chips being impregnated, in a liquid containing black liquor, in a concurrent impregnation zone (5), the chips being cooked in a cooking zone (6) subsequent to the impregnation zone, hot black liquor (7) being extracted from at least one extraction screen section (8), and cooked pulp being discharged (9) at the other end of the digester. The chips are, when they leave the high-pressure feeder (2), included in a first liquid, which first liquid is in the main separated from the chips in a liquid exchanger (4) installed in the transfer line (2A, 4A) and is replaced by a second liquid which contains black liquor.
