Mixing a variety of solids with a liquid and mashing it all to form a homogeneous organic suspension suitable for bacteria – that is the PreMix’s strength. This is why the solid matter feeder is just as suited for renewable resources as well as other input materials – whether that means pasty food waste, bulky crops or organic waste.
One decisive advantage of the solid matter feeder PreMix is its foreign matter separator and the preparation of the biomass, even before the integrated positive displacement pump: After the biomass has been fed to the solid matter feeder via a screw conveyor, the first step is to separate out the heavy material. Then, coarse particles are crushed and fibrous matter is cutted. Right from the start, this smart concept thus avoids damage from stones, metal parts and other heavy material and ensures that the biomass is properly prepared for the bacteria. One PreMix can supply several digesters. A drive power of 20 to 50 kW is sufficient (depending upon the model) for delivery rates from 20 to over 100 m3/h.
Due to its compact design, just a few square meters are enough to set up the PreMix – including space for service and maintenance work. This makes the installation and integration into new systems or the update of existing biogas plants easy, and operators can flexibly make use of the most varied biomass, without having to change the parameters for the solid matter feeder for every change. Combined with a Vogelsang Performance Cut Control (PCU), the solid matter feeder is ready to be automated.
