Patent ID: 6986829

Claim:
A process for stacking and diluting paper fiber stock comprising: stacking a high-consistency paper fiber stock in a first volume for a defined dwell time; conveying the high-consistency paper fiber stock to a second volume arranged to adjoin downstream the first volume; diluting the high-consistency paper fiber stock in the second volume at least to a pumpable consistency; drawing off the diluted paper fiber stock as a suspension through a wire; generating a circulation flow in the second volume, whereby the circulation flow facilitates the conveying of the high-consistency paper fiber stock located on boundary of the first volume into the second volume, the diluting of the high-consistency paper fiber stock, and the drawing of the diluted paper fiber stock through the wire; rotating a rotor to keep the wire clear; and generating, with a screw coil arranged directly in front of the rotor, a flow that runs in an axial direction of the screw coil and guides the diluted suspension away from the wire.
