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.
