Fermentation residue conditioner 1 for conditioning aggregate materials 3 consisting of fermentation residue, sludge, and/or organic residual masses with high water content, particularly of fermentation residues from the fermentation of household waste, bio-waste and/or base materials containing food residues, having a fermentation residue dropping point 4 for introducing the aggregate material 3 and a fermentation residue removal point 5 for removing the aggregate material 3. The fermentation residue conditioner 1 is designed such that the aggregate material 3 is transportable through the fermentation residue conditioner 1 during conditioning. The fermentation residue conditioner 1 has a deposit surface 2 for supporting the aggregate material 3 from the underside, and which is designed such that the transport of the aggregate material 3 can be effected by said deposit surface 2.
