A system for feeding fibres from a fibre separation step at a first pressure to a drying step at a second, lower pressure, the system comprising a sluice feeder ( 3 ) provided between the fibre separation step and the drying step. At least an outlet ( 14 ) of the sluice feeder ( 3 ) is enclosed by a housing ( 4 ) for pressurization by means of a pressure medium in the housing ( 4 ) to a pressure that essentially corresponds to the first pressure in the sluice feeder ( 3 ). The fed out fibre from the sluice feeder ( 3 ) to the housing ( 4 ) are removable by means of the pressure medium in the housing ( 4 ) via a control valve ( 20 ), which regulates the pressure in the housing ( 4 ), to the drying step at the second, lower pressure. The pressurization in the housing ( 4 ) prevents steam to escape from the sluice feeder ( 3 ). A method for feeding fibres, the fibres are fed to a sluice feeder ( 3 ) which is pressurized from the outside by means of a pressure medium and are fed out by means of the pressure medium via a pressure regulating control valve ( 20 ) to the drying step. |
