<p>The invention concerns homogeneous at least partial sterilisation or homogeneous complete pasteurisation of a substrate. In a first step of the method, the substrate is loaded via a loading area of a sealed hollow vessel at a first end of the vessel. A fluid for moistening said substrate may be introduced into the vessel, the vessel being further provided with means for at least partly sterilising or pasteurising the moistened substrate. In a second step, the substrate is passed through a bounded zone of transport towards the front of the machine until it reaches the other end of thereof. In a third step, the substrate is passed through a zone of transport towards the rear of the vessel so as to return the substrate to the first end, the zones of transport towards the front and towards the rear being separated from each other by a tubular partition. During the return transport the substrate may be subjected to tumbling. The second and third steps are repeated as many times as necessary to obtain homogeneous and at least partial sterilisation or homogeneous and complete pasteurisation of said substrate. A machine is also described for carrying out the method. Application to sterilising or pasteurising organic substrate such as growth media for plants or mushrooms.</p> |
