Abstract (en)
[origin: EP2202052A1] The method involves supplying a fibrous material over a stiffening screw (1), and dispensing a feed screw (9) directly by a dispenser (2), where the feed screw is provided adjacent to the stiffening screw. The fibrous material is pre-dehydrated in dehydrating modules (7, 11) before the stiffening screw and is dehydrated in the stiffening screw. An initial dehydration of the fibrous material is performed by a disc filter before the stiffening screw, and a directly processed dehydration process is performed by the stiffening screw. An independent claim is also included for a device for dehydrating and dispersing fibrous material, comprising a stiffing screw.
