Landia (UK) Heat-processing plant enables environmental and commercial use of animal by-products and waste at bio-gas plants. This heat-processing plant includes heat jacket, pump, mixing system with stainless steel valves, automatic control and a monitor. Suitable for Category-3 by-products and waste, the Landia BioChop heat treatment plant is located in the process before the digester and thus serves not only as a heating unit but also as a mixing chamber for the products received at the plant. Typically containing large dry matter particles which need to be chopped, macerated and mixed with liquid, the Landia heat treatment plant is designed to chop and mix the products and pump the substrate to the digester – all by the same pump.
