Wet Hammer Mill IMPRA
Optimises your biogas plant
- Reduce substrate costs, increase fermenter performance without additional fermentation volume
- Up to 15% more biogas with the same raw material input
- Easy integration into the fermenter bypass
- Energy savings due to lower substrate viscosity
- Makes difficult substrates usable
Recommended for
Up to 15% More Biogas With the Same Raw Material Input
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.
Take Advantage of these Benefits
Reduce Substrate Costs, Increase Fermenter Capacity, Reduce Load on the Fermentation
- Up to 15 % more biogas with the same raw material input
- Impra pays for itself after a few years
- Makes even difficult substrates usable such as grass and manure
- Typical substrates: clover, silage, dung or straw, crops such as grain, oilseeds, potatoes and beet
- More output, higher space load possible
- Energy savings through less viscosity with Impra
- Better pumping and stirring properties
- No floating layer
- Energyefficiency, interval operation enables load management, savings on pumps and agitators
Reliable Operation and Long Durability
- Robust welded construction for continuous industrial operation (24/7)
- Made entirely of corrosion-resistant stainless steel
- Proven many times in practical use since 2011
High Availability with Low Downtimes
- High contaminant tolerance due to integrated foreign particle separator
- Minimal effort for maintenance and wear
High Safety of Personnel and Plant
- Standstill monitoring with door safety lock
- Discharge hopper with overfill protection
- Sensors for bearing temperature monitoring
Impurities are sorted out
Discharge pump transports processed substrate to AD plant
