<p>A process for treating a mixture of substances (2) containing structured constituents and organic matter which is received in the form of bulk material and subjected to aerobic drying in a reactor by means of a flow of process air through the material and/or addition of a leaching fluid, so that the soluble organic constituents are discharged. The mixture of substances (2) is subjected to pulse-type or periodical application of pressurised air having a pressure of more than 200 kPa and directed perpendicular to and/or in parallel with the direction of displacement of said mixture of substances. A device includes a reactor (1) having associated a charging means (4) for introduction of the mixture of substances, wherein inlets (14, 18) for introducing process air are arranged in the bottom portion and or in the head portion of said reactor and a distributor (20) for leaching fluid is arranged in the head portion of said reactor. Air is supplied with pressurised air system in the form of pulses or periodically for decomposition of said bulk material, wherein the discharge means are in the bottom portion of said reactor.</p> |
