Effective substrate digestion with Imprasyn

Biogasanlage Substrat

Future-oriented biogas production calls for an increase in efficiency across all system types, both in terms of technical equipment as well as the flexible use of biomass.  Solids and liquids can be broken down to cell structure and – depending on the substrate and requirements – mixed with a additive in Imprasyn systems, using just one process step. As a result, the Imprasyn process dissolves more nutrients from fibres and stalks. It therefore also means that raw materials that are difficult to ferment can be used in previously unattainable quantities. Imprasyn converts the fermentation substrate into a flowable form. This allows us to increase the gas yield of agricultural systems by up to 15 percent – with the same raw material input. This involves taking the substrate directly from the fermenter and pumping it back into the fermenter further into the secondary fermenter after processing.

Expertise for more than 60 years
Process engineering for your biogas system

We apply our system expertise to your biogas unit. You define the framework conditions and requirements for your system, and we will configure the ideal output, equipment and support for your Imprasyn process. The objective is to achieve the shortest possible Imprasyn operating times and for this to be integrated into an optimal load management system.

With our technology, usable cellulose contained in grass, solid manure and straw is efficiently utilised for biogas production.

When it comes to the pure grinding of dry straw upstream of the fermenter for straw mono-digestion, we also know our stuff. We have developed the SD straw hammer mill especially for the dry grinding of fibrous material such as straw, hay, maize cobs, lucerne, miscanthus, hemp or jute.

We ensure peak economic and ecological performance with maximum energy yield with the Imprasyn crusher. Our objective is to achieve the best possible breakdown of energy crops as well as residual and waste materials for the efficiency of your system. Our technology makes efficient use of exploitable cellulose contained in grass, solid manure and straw for biogas production.

Your advantages with Imprasyn:

  • Higher gas yield
  • Lower retention times, for better use of the available container volume
  • Use of alternative raw materials
  • Less or no floating layers
  • Less wear

The SD straw mill is specially adapted to the grinding of straw due to its special geometry. The result is high throughput and low energy consumption. Low bulk densities and very large volumes of processed straw pose no problems for the SD. The straw can be easily broken down to the typical fineness of 10 mm or less (depending on the specifications of the fermenter manufacturer) and is thus optimally prepared for anaerobic digestion. The dry straw is transported pneumatically in an energy-efficient and low-wear manner. Grinding module – pneumatic discharge

Like all our mills, the SD meets the highest industry standards and is designed for continuous use over many years.

Once the straw has been broken down, we can efficiently and reliably mix it with your fermentation substrate or slurry so that it can be fed directly into the biogas plant after processing.

In straw mono-digestion, the IMPRASYN system can additionally be used as a stock preparation system to further break down the fibres in the process. In combination with the SD, IMPRASYN then acts as a kind of booster for biogas production.

Extra yield due to Imprasyn

“Imprasyn can be used to reliably and effectively utilise even the most difficult substrates of your greening area, such as grass, catch crops or GPS, for your biogas plant.”

Our benefits for biogas systems

Tailored solutions for your biogas system

You integrate Imprasyn as a module into existing pump systems or select the plug-and-play solution in the ready-to-use container. The system is available in two performance classes. We work together to determine the most profitable configuration for you.

The use of low-cost raw materials means that the Imprasyn process pays for itself after only a short time. Other side effect: Due to lower raw material demand, the required cultivation area is reduced, the volume of the repository, the area for spreading, the energy consumption for pumps and agitators and their wear and tear.

Systems engineering services throughout the world
