Abstract

The present invention provides a fibre processing apparatus for use in the mechanical manipulation and/or processing of a material. The apparatus includes an inlet at a first end for the introduction of the material and/or liquid in which the material is contained, an outlet downstream of the inlet and via which the manipulated and/or processed material and/or liquid leaves, and intermediate the inlet and outlet there is provided a screw processor including at least one shaft with an axis of rotation and on which is provided a plurality of elements provided to cause mechanical manipulation and/or processing and/or cutting of the material, in use. At least one of said elements includes an exterior surface or wall that is at least partially textured. Typically, the material being manipulated and/or processed can be any from the following group: fibres, cellulose fibres, powders, granules, foodstuffs, pharmaceuticals and/or plastics. The present invention also provides an element for use with a screw processor, and a method of treating a composition comprising cellulose fibres.

Abstract

The present invention provides a fibre processing apparatus for the modification fibrous material. The apparatus includes at least one housing body, which has an inlet and an outlet through which fibrous material may flow along a flow path, in use. The housing body further comprises a plurality of fibre modification sections sequentially arranged along the flow path. The apparatus also includes one or more rotatable shaft members provided within the housing body and provided to extend along the flow path from a first end in a first modification section to a second, opposing end in a final modification section. A first plurality of the modification sections includes compression and/or pressure-based modification means, and a second plurality of the modification sections includes mechanical modification means.
