An apparatus for treating fibrous material is disclosed. The apparatus may
include a fiber separator, a de-liquefier, a dry-to-wet blender and a
flash dryer. The fiber separator may be a liquid-based fiber separator.
The de-liquefier is for removing liquid from the fibrous material. The
blender downstream, which may be a dry-to-wet blender, is for adding a
dry material to the de-liquefied fibrous material. The de-liquefier and a
dry-to-wet blender are downstream from the fiber separator and the
dry-to-wet blender may be downstream from the de-liquefier. The flash
dryer, which is even further downstream, is for drying the treated
fibrous material.
