<p>1. Digester comprising an enclosure (1), an inlet duct (7) for the material to be digested which opens towards the bottom of the enclosure (1), an outlet duct (9) for the digested material which opens in the enclosure (1) at a level higher than the opening of the inlet duct (7) and at a distance therefrom in a horizontal direction, an outlet duct (12) for gas which opens from the top of the enclosure (1), and heat control means (4) for the enclosure (1), characterized by a first partition (15) running from the bottom (11) of the enclosure (1) which is interposed, in the said horizontal direction, between the mouths of the inlet and outlet ducts (7, 9), thus dividing the enclosure (1) into a first compartment (18) and a chamber, which only communicate with one another above the free edge (22) of the partition (15), which is at a level intermediate between the two mouths, and by at least one second partition (16) running from the bottom (11) of the enclosure (1) which is interposed, in the said horizontal direction, between the first partition (15) and the mouth of the outlet duct (9), thus sub-dividing the chamber into second and third compartments (19, 20) which only communicate with one another above the free edge (23) of the second partition (16), which is at a lower level than the free edge (22) of the first partition (15).</p> |
