Method and device for increasing the dry matter content of manure by storing stackable manure, in particular poultry manure

摘要

For increasing the dry matter content of manure, in particular poulty manure, this manure is stored in at least one essentially closed, roofed chamber having cavity walls (2), of which the inner walls (2b) are gas-permeable. Stable air or outside air being admitted to the cavity. In this roofed chamber (1) a controlled amount of air is passed over the manure at least partly via the cavity (8). The mixture, produced in the chamber by heating, of essentially ammonia, smell and water vapour penetrates at least partly via the inner walls into the cavity (8) and is removed from the chamber with the ventilation air and is converted into liquid aqueous ammonia in a chemical scrubber (16). The pH is kept at a value lower than 6 by metered addition of acid. Condensed water formed by condensation on the uninsulated outer walls and fed into the cavity by dripping from the insulated sloping roof is drained therefrom.
