Abrégé

The invention relates to a device for the hydrolysis of preferably solid organic substrates, in particular of energy crops and plant residues, with a collection vessel (1) for receiving the organic substrates, with a conveying means (4) for transporting the organic substrates into a charging device (7) for the batch-wise charging of a hydrolyzer (10) with the organic substrates, the hydrolyzer (10) being provided on the output with a pressure-release device (12) having a valve-controlled pressure diaphragm (13) and a steam trap (14) arranged upstream of an expander tank (15). According to the invention, the conveying means (4) includes a conveyor worm (4') with a sleeve shaft (25), which is charged with hot steam from the steam trap (14), which is preferably designed as a cyclone, the sleeve shaft (25), in the conveying zone for the organic substrate, having, in a heating zone (18), steam-outlet openings (26) for directly charging the organic substrate with hot steam.
