Abstract:
Apparatus for cooking-dehydration and sterilization-drying of organic wastes, comprises a chamber (1) heated by a double walled enclosure (2) that communicates with fire tubes (3), the enclosure (2) receiving hot gases from a firebox (4). The hot gases pass through conduits (5) to diffusion nozzles (6) immersed in the products (7) to be dried. Some of the combustion gases are recycled by a ventilator (8) via a conduit (9) and a cyclone (10) to the firebox (4). The ventilator (8) draws in fresh air through a preheating heat exchanger (11) that is heated by the combustion gases which are then vented.
