Abstract
A device for the aerobic treatment, conditioning and/or drying of moist, substantially solid or paste-like, at least partly organic material, has a vessel containing paired, Venetian-blind-like walls, with adjustable blades, forming at least one reaction chamber, at least one air inlet chamber and at least one air discharge chamber, and containing supports which are in spatially staggered array inside the reaction chamber in such a way that they provide the best possible pressure relief for the filling. The invention also relates to a process using said device.

A device (1) for the aerobic treatment, conditioning and/or drying of moist, essentially solid or pasty material, based on
- a vessel (2, 13 ) having a divided interior in which supports (8a, 8b, 8c, 8d, 26) are arranged, the interior being divided by at least one pair of air-permeable walls in such a way that those sides of the walls (insides) of such a pair which face one another form a reaction chamber (4, 15a,15b, 30, 31) while the sides facing away from one another (outsides) form at least one air inlet chamber (5, 16a, 16b) and at least one outlet air chamber (6, 17), and
- additional means, selected from transport and conveyor means, filling and discharge devices, air pipes, fans, valves, flaps, sliding valves, control and regulating means, wherein
- a) the walls essentially consist of a Venetian-blind-like construction (3a, 3b, 14a, 14b, 14c, 14d, 29a, 29b, 32a, 32b) in which the blades (10, 10a, 10b, 18) are arranged with predetermined blade angles, distances, lengths and/or widths and
- b) the supports (8a, 8b, 8c, 8d, 26) are spatially arranged and are in staggered array inside the reaction chamber (4, 15a, 15b, 30, 31) in such a way that they reduce the pressure applied to the moisture-laden material and thus make it possible to achieve a loosened bed.
A process for the aerobic treatment, conditioning and/or drying of moist, substantially solid or paste-like material, using a device comprising a vessel (2, 13) having a divided interior in which supports (8a, 8b, 8c, 8d, 26) are arranged, the interior being divided by at least one pair of air-permeable walls in such a way that those sides of the walls (insides) of such a pair which face one another form a reaction chamber (4, 15a, 15b, 30, 31) while the sides facing away from one another (outsides) form at least one air inlet chamber (5, 16a, 16b) and at least one outlet air chamber (6, 17), and
- additional means, selected from transport and conveyor means, filling and discharge devices, air pipes, fans, valves, flaps, sliding valves, control and regulating means, wherein the walls essentially consist of a Venetian-blind-like construction (3a, 3b, 14a, 14b, 14c, 14d, 29a, 29b, 32a, 32b) in which the blades (10, 10a,10b, 18) are arranged with predetermined blade angles, distances, lengths and/or widths and the supports (8a, 8b, 8c, 8d, 26) are spatially arranged and are in staggered array inside the reaction chamber (4, 15a, 15b, 30, 31) in such a way that they reduce the pressure applied to the moisture-laden material and thus make it possible to achieve a loosened bed, wherein the ventilation and venting of the reaction chambers (4, 15a, 15b, 30, 31) is controlled by changing the fan power and/or adjusting the valves in the air inlet and air outlet pipes (22, 23) and/or adjusting the angle of the blades (10, 10a, 10b, 18).
