ABSTRACT:
A feeding system for feeding comminuted cellulose containing material and liquid to a continuously operating treatment vessel. The feeding system comprises a chute, operating at a first pressure, a high pressure feeder sluices the material to a second pressure, that is higher than the first pressure, for further conveyance to the treatment vessel. The high pressure feeder also receives a return liquid flow from the treatment vessel at the second pressure and recirculates a recirculation flow to the chute. The high pressure feeder is in fluid communications, regarding both the liquid and the material, with the recirculation flow when any of the pockets of the high pressure feeder is in a location which corresponds to an outlet for the recirculation flow.
