ABSTRACT:
An apparatus produces elongate multi-fiber particles of extremely small size to facilitate substantially complete penetration of high consistency pulp fibers by ozone when exposed thereto. A housing is provided having first and second ends and a substantially smooth interior housing surface. A means is provided for introducing high consistency wood pulp into the housing. A source of ozone gas bleaches the high consistency pulp within the housing. A pin rotor is rotatably mounted within the housing, and includes a plurality of pins, each pin having a pin tip. A means is provided means for limiting the build up of high consistency pulp fiber accretions on the pin tips.
