A German research team based at a technical university with expertise in high-voltage techniques developed a novel low–energy extraction technology for organic materials based on electrical gas discharging. Looking for industrial and applied research partners from bioenergy and food sector (e.g. manufacturers of bioethanol, sugar, oils, starch, spices, tea etc.) for technical cooperation agreements.
A German research team of a Technical University with expertise in high-voltage techniques developed a novel low–energy extraction technology for organic materials based on electrical gas discharging.
A key issue for the utilization of organic materials is their disintegration and the associated release of valuable ingredients and compounds. Hence, an energy-efficient direct disruption of the surface and cells of organic materials is desired for a faster and more efficient extraction of the substances required. The novel technology includes the treatment of organic process material (like biomass) by low-energy electrical gas discharges produced by a special high-voltage electrode device, leading to a significant and sustained perforation of the cellular structures. The perforation of a leaf has illustrated that water rapidly evaporates via a multitude of micro holes in the destructed leaf‘s surface. The perforated leaf shrinks within a few minutes demonstrating a substantially accelerated dehydration. The picture below shows the visual result of the new rapid drying technology demonstrated with green leaves: untreated leaf (left) and treated leaf (right), both harvested at the same time.
The required high voltage is generated by the resonant magnetic coupling of at least two oscillating electrical circuits.
The high efficiency of the method has been demonstrated for various organic materials. As part of a biogas plant the technology was successfully adopted to green waste to allow rapid glucose extraction
Looking for industrial end users and applied resarch partners dealing with biogas/bioethanol/food production and relevant equipment. technical cooperation Agreements sought.
- High energy efficiency: saving about 20% of energy costs allowing a more efficient bioenergy production
- Accelerated release and more effective exploitation of valuable compounds from organic materials
Most benefits by
- desiccation of organic materials,
- extraction of content from fruits, foliage a.o.
- Integration of the technology into existing working processing.
This novel technology has still not been used under practical conditions until now: there are no relevant competitors working with this extraction technology (patent search/market recherches done).
