Abstract
A high pressure transfer device for feeding wood chips to a digester in the production of paper pulp has enhanced efficiency. A rotor having first and second sets of through extending conduits is mounted for rotation in a housing having first through fourth ports associated with each set, with a screen at the third port of each set for screening wood chips out of liquid passing through that third port. The third port of each set is connected to its own distinct source of suction, so as to enhance filling efficiency of the rotor.
