Method for refining plant fibers by steam explosion

Industrial system for refining plant fibers by steam explosion, comprising:

• a pre-chamber (42),
• a loader for loading the pre-chamber (42) with sheaves (24) of a fibrous plant,
• a blow-out unit (44) disposed under the pre-chamber (42),
• a valve (41) upstream from the pre-chamber (42),
• a valve (43) separating the pre-chamber (42) and the blow-out unit (44) when in a closed state and opening a passage with a diameter of at least a smallest of the diameters of the pre-chamber (42) and the blow-out unit (44) when in an open state,
• a washing system (46) disposed inside the blow-out unit (44) for washing the blow-out unit and dragging the fibers downward,
• a mobile basket (48) for receiving fibers with a position under the blow-out unit (44) for receiving fibers,
• a liquid-recovery device (49), disposed under the basket (48) and under the blow-out unit (44),
• a receiving chamber receiving the basket (48) loaded with fibers, and
• a spin-drying chamber.
