ABSTRACT:
An improved hydropulper and mixer for pulp production and associated tasks, in particular for gently re-hydrating and separating processed fiber. The apparatus comprises a vessel, a lower chamber containing a rotatory mechanism, a rotary drive and a tube for re-circulating the slurry. A sized aperture in the bottom of the vessel, which controls vortexing and excessive swirling, opens into the chamber. The chamber safely encloses a vanned rotor which vigorously pulps the fiber while impelling the flow through an outlet and tube back to the vessel. The slurry recycles until the quality is judged satisfactory. A de-watering screen can then be introduced into the flow, saving the water for re-use, or the slurry can be redirected to another location by the same integral pumping action.
