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.
Your Advantages
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
INCREASE BIOGAS YIELD THROUGH OPTIMALLY DIGESTED BIOMASS
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:
- Biogas yield increased
- Lower retention times, for better utilization of the available tank volume
- Less biomass needed
- Make difficult substrates usable
- Reduce required acreage by utilizing residues
Low energy consumption increases efficiency of the biogas plant
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:
- Energy savings in the operation of the agitator and pumps.
- No floating layers
Structure and function of IMPRA for biogas plants
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.
