New mixing system defeats biogas digester crust at leading pig producer

New mixing system defeats biogas digester crust at leading pig producer Anaerobic-Digestion A thick floating layer of crust that was hampering the biogas operation of a forward-thinking Danish pig producer has been defeated by the GasMix digester mixing system from ABC member Landia. The Roslev-based business (established 1933), which includes pig production, plant breeding and green energy, first encountered problems with its existing propeller stirrers when a steel wire broke, as Ny Rybjerggaard's owner, Jens Henry Christensen explains: "In one of our reactor tanks (3300 m³), it transpired that a stirrer that was meant to be operating at the top of the digester had only been running at the bottom, because the wire to raise the propeller stirrer was broken. In no time at all, a floating layer had formed at the top." READ MORE
