  • a composting of the spent grains speaks for the fact that a high quality product for Soil improvement is formed, however, the sales market is only small and so is the production costly that it does not cover costs.
  • Beer spent grains are also suitable for the production of biogas, but are high for this Investment costs for a biogas plant required.
  • Direct combustion is an energetically practicable recycling process for beer spent grains. From the magazine “Brauwelt” No. 26 (1988), pages 1156 to 1158, "The energetic Utilization of beer spent grains ", is a process for producing energy from beer spent grains, such as described at the beginning, known. Beer spent grains incinerators work because of that intensive pre-drying (beer spent grains initially contain 75 to 80% by mass Water) and, due to the relatively poor calorific value of the spent beer, not very effective.
  • the invention aims at avoiding these disadvantages and difficulties and presents itself the task, a method of the type described above and a system for To carry out the process to create an energetically optimal, i.e. to Possibility of profitable utilization of beer grapes.
  • the Dried the spent grains with as much external energy as possible that the spent grains can be thermally recycled without auxiliary firing, i.e. burned or can be gassed.
  • the gas produced in the gasification is advantageously used for energy, preferably as Energy sources for steam generation in the brewery network, e.g. as additional gas to natural gas, so that it is energetically burned by the boiler system in the brewery can be used.
  • An additional one is preferably used for mechanical pre-drying of the spent grains Drying to remove capillary water using electrical fields or with Helped by high frequency fields.
  • the mechanical predrying is advantageously carried out to at least 65, preferably at least 62 mass% water content.
  • the thermal drying of the spent grains takes place advantageously on their self-firing permitting water content, preferably to at least 55 mass% water content.
  • the mechanical predrying Pressed water formed is processed anaerobically and the resulting methane-containing gas used energetically, preferably as an energy source for steam generation in the Brewery association used.
  • Exhaust gases produced when the dried beer spent grains are burned become inexpensive disposed of together with waste gases formed in a steam boiler of the brewery.
  • mixtures of beer spent grains and other organic, biogenic waste thermally recycled.
  • a system for carrying out the process with a beer spent grains a first Drying stage forming mechanical dryer and with one for mechanical dewatered spent grains a further drying stage forming thermal dryer as well with a device for thermal recovery by burning or gasifying the dried beer spent grains, is characterized in that in the thermal dryer Flue gas leading from a steam boiler of the brewery energy association leads out.
  • the device for thermal recycling of the beer spent grains preferably has one Combustion boiler on, where appropriate the combustion boiler with a Steam generating device is equipped and the steam generating device is advantageous is linked to the brewery's energy network.
  • a flue gas discharge from the combustion boiler ends up saving investment an exhaust system of a beer production system, where appropriate an exhaust pipe from thermal dryer also opens into the exhaust system of the beer production system.
  • the device for thermal Recycling a gasification device where appropriate one of the Gasification device outgoing and leading in the gasifier generated gases discharging line a burner of a steam boiler of the brewery's energy network.
  • the mechanical dryer can preferably be used as a belt press or as a screw press be trained.
  • a convection dryer is useful as a thermal dryer.
  • the thermal dryer preferably has one that can be operated with solar energy Drying facility.
  • the thermal drying, the Gasification and combustion combined in one apparatus, whereby expediently a the hot exhaust gases from the thermal drying, gasification and the device having the combustion discharge line directly to the steam boiler of the brewery's energy consumer.
  • the thermal drying can be operated with a solar energy Drying facility to be expanded.
  • FIGS. 1 and 2 each a process diagram illustrate according to a variant.

  • the boiler 10 is supplied with natural gas, which is supplied via line 9, heated; the steam-carrying pipes are designated 11. Part of the flue gas can via a branch line 12 directly to an exhaust fan 13 of the flue gas disposal system be fed. This also leads to the flue gas disposal system Drum dryer 6 outgoing flue gas discharge 14.
  • the water content can be reduced to below 55% by mass lower so that the spent grains 15 after ignition, i.e. without support firing, burn.
  • the dried beer spent grains 15 are burned in a burner 16 in one Combustion boiler 17 in which a steam generating device 18 is installed.
  • the in this steam generating device 18 steam is usefully for the Beer production, i.e. that natural gas-fired for the natural gas burner 19 Boiler 10 can be saved.
  • the ash discharge is designated 20.
  • the wet beer spent grains 1 are first in a first drying stage 2 by means of a belt press 21 of a mechanical Subjected to drying. Then the mechanically dewatered spent grains are used as Convection dryer 22 designed thermal dryer of the second drying stage 4th supplied, in which the spent beer 5 as well as shown in FIG. 1 with flue gas, which from a Beer production plant 8 comes to a water content below the self-burning limit be dried.
