Efficiently, the wet hammer mill Impra processes only what your biogas plant cannot manage on its own, and thus increases the biomass yield.
Biomass is taken directly from the digester and returned there after processing or fed into the post digester. Impra works like a ruminant: the wet shredder and microorganisms together mobilize hard-to-remove nutrients from lignified fibers and other hard-to-digest materials.
Up to 15% more biogas with the same raw material input, such as manure, silage or even grain residues
The substrate is more liquefied by Impra and can be pumped and stirred more easily in the biogas plant. This saves electricity, which is used for processing.
The core component of the Impra process is the wet shredder, which is made entirely of stainless steel except for the wear parts. Depending on the size, the machine is equipped with a 75 or 37 kW motor.
Impra’s goal is the best possible digestion of energy crops as well as residual and waste materials for the efficiency of your plant. With this technology, usable cellulose contained in grass, solid manure and straw is efficiently utilized for biogas production.
Advantages of optimally digested biomass:
Another advantage of an integrated Impra system is the homogenization of the substrate in the digester. The viscosity is extremely reduced and therefore the content is much better stirrable and pumpable:
Grinding chamber for biomass
In the grinding chamber, fast-rotating, hardened beaters crush the substrate. A screening circle completely closes off the grinding chamber. The screen perforation determines the degree of size reduction for the entire substrate, independent of throughput and wear. Different substrates can be accommodated by adjusting the screens. Wear parts can be replaced quickly and easily via two large housing doors.
Separation of impurities protects biogas plant
Impurities are sorted out and collected in the foreign matter catcher. The housing is protected by armored, replaceable wear segments.
Eccentric pumps meter substrate for biogas plant
Two eccentric pumps ensure exact metering of the material and conveyance into any number of containers. The self-regulating conveying system works load-dependently from the main drive and guarantees the always optimal utilization of the IMPRA system.
