ABSTRACT:
The manure, which has been previously finely ground, is diluted (3) so as to form a liquid mixture containing not more than 4% of solid material. This mixture is fed into a bioreactor (6) of which the gas is used to feed the burner (11) of a dryer (10) in which the manure particles are dried. Before and after passage of the mixture into the bioreactor, filaments and fibres are separated (4,9). At least part of the liquid separated in the second separator (9) is recycled (13) in the initial liquid mixture. The energy of the water vapor from the drying is used to activate the bioreactor (16). The residual liquid not recycled is subjected to a nitrifying/de-nitrifying treatment (15). The residual mud may be collected (23) and mixed with the dried product, as well as the fibres and filaments eliminated. The mud, the filaments and the fibres, rich in proteins, may be used directly as foodstuff for cattle. The other residual product are appropriate for use as fertilizers.
