Abstract (en)
[origin: WO2019122694A1] The invention relates to an industrial system for refining plant fibres by steam explosion, comprising: - a pre-chamber (42), - a loader for loading the pre-chamber (42) with sheaves (24) of a fibrous plant, - a spark gap (44) arranged under the pre-chamber (42), - a valve (41) upstream of the pre-chamber (42), - a valve (43) separating the pre-chamber (42) from the spark gap (44) when in the closed state and opening a passage with a diameter of at least the smallest of the diameters of the pre-chamber (42) and the spark gap (44) when in the open state; - a washing system (46) arranged inside the spark gap (44) for washing the spark gap and dragging the fibres downwards; - a mobile basket (48) for receiving fibres with a position under the spark gap (44) for receiving fibres; - a liquid-recovery device (49), arranged under the basket (48) and under the spark gap (44), - a receiving chamber receiving the basket (48) loaded with fibres; and - a drying chamber.
