Abstract
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.
Claims65
An apparatus for treating fibrous material, said apparatus comprising:
- (a) a liquid-based fiber separator;
- (b) a de-liquefier downstream from said liquid-based fiber separator for removing liquid from the fibrous material;
- and
- (c) a blender downstream from said liquid-based fiber separator for adding a supplementary material to the de-liquefied fibrous material.
An apparatus for treating fibrous materials, said apparatus comprising:
- (a) a de-liquefier for removing liquid from the fibrous material;
- and
- (b) a dry-to-wet blender downstream from said de-liquefier for adding a dry material to the de-liquefied fibrous material.
An apparatus for treating fibrous material, said apparatus comprising:
- (a) a liquid-based fiber separator;
- (b) a de-liquefier downstream from said liquid-based fiber separator for removing liquid from the fibrous material;
- (c) a dry-to-wet blender downstream from said liquid-based fiber separator for adding a dry material to the de-liquefied fibrous material;
- and
- (d) a flash dryer for drying the treated fibrous material.
A method for making treating fibrous material, said method comprising the steps of:
- (a) providing a fibrous material precursor to a liquid-based fiber separator to create a fibrous material slush;
- (b) removing at least a portion of the liquid from said fibrous material slush to yield a fibrous material;
- and
- (c) blending a supplementary material with said fibrous material to yield a treated fibrous material.
A method for making treating fibrous material, said method comprising the steps of:
- (a) removing at least a portion of the liquid from said fibrous material slush to yield a fibrous material;
- and
- (b) blending a dry material with said fibrous material to yield a treated fibrous material.

- (a) providing a fibrous material precursor to a liquid-based fiber separator to create a fibrous material slush;
- (b) removing at least a portion of the liquid from said fibrous material slush to yield a fibrous material;
- (c) blending a dry material with said fibrous material to yield a treated fibrous material;
- and
- (d) flash drying said treated fibrous material.
A treated fibrous material, wherein said treated fibrous material is substantially homogeneous prior to classification.
A treated cellulosic, fibrous material, wherein said treated fibrous material is substantially homogeneous and aggregate-free prior to classification.
A treated cellulosic, fibrous material, wherein said cellulosic, fibrous material is substantially homogeneous and aggregate-free prior to classification, said cellulosic, fibrous material further including a supplementary material substantially uniformly covering the surface of said cellulosic, fibrous material.
