Sluice feeders for introducing finely divided chips into vessels under pressure
Abstract
Abstract A sluice feeder for introducing finely divided vegetable material (hereinafte referred to as "chips") into a pressure vessel, in which the sluice feeder is formed with a rotor encased within a housing having chip inlet and outlet openings, and liquid inlet and outlet openings. The rotor is formed with a plurality of chip receiving pockets extending axially over the rotor. Extending along one of the journals of the rotor in alignment with each pocket is a liquid conducting channel leading from the rotor pocket to the end of the journal. By forming the liquid feed channels to extend along the longitudinal axis of the journals, to the rotor, the number of rotor pockets for receipt of the chips may be significantly increased.
