Method and device for the treatment of organic residual products of biogas systems

A device for recycling biomass containing interconnected:

• a) a fermentation tank and means for generating a biogas,
• b) means for separating a digestate from the fermentation tank,
• c) means for concentrating the digestate, the concentration forming a cake as well as a liquid fraction,
• d) means for separating a concentrate from the liquid fraction, as well as
• e) means for conditioning the concentrated cake, and
• f) means for a controllable transposition of parts of the resulting concentrate into the conditioned cake.

Use of a device for recycling biomass containing interconnected:

• a) a fermentation tank and means for generating a biogas,
• b) means for separating a digestate from the fermentation tank,
• c) means for concentrating the digestate, the concentration forming a cake as well as a liquid fraction,
• d) means for separating a concentrate from the liquid fraction, as well as
• e) means for conditioning the concentrated cake, and
• f) means for a controllable transposition of parts of the resulting concentrate into the conditioned cake.
• for implementing a method for processing organic residuals materializing in a fermenter and subjected to mechanical conditioning comprising at least one concentration step, wherein subsequent to mechanical conditioning a resulting digestate liquid flow therefrom is subjected to treatment for the production of a concentrated top fertilizer dressing, on the one hand, and, on the other a condensate, and the digestate cake stemming from concentration is run through a dryer for the production of a base fertilizer dressing and wherein for its enrichment with energy recyclable materials the partial flow of the base dressing production receives a controllable fraction of the top dressing, for generating electricity and/or heat or for the production of fertilizer dressings.
