Definitions

  • the drying process according to the method step mentioned second or in accordance with method step 1.2) is usually a post-drying process with the aid of which the biomass to be reprocessed is reduced in terms of its moisture content, usually in the single-digit weight percent range, ie. H. in the range between about 1 wt .-% to 9 wt .-%.
  • the harvesting efficiency achieved with the known device has proven to be relatively low in practice. In addition, no high densities were achieved.
  • the harvesting machine described was or is designed to be self-propelled, wherein the wheels are driven by the already mentioned internal combustion engine. As a result, the weight of the plant is high and for the compaction of the biomass is less energy available.
  • the prior art also includes a process for the production of animal bedding from Miscanthus, such as the DE 10 2005 057 348 A1 describes, which is to classify only as generic.
  • the aforementioned plant material is formed by pressure and temperature over a suitable period of time followed by cooling and curing to cylindrical pellets.
  • the Miscanthus / straw pieces are also fed to a hammer mill, in which they are connected to a Bale breaker learn a further crushing.

  • a hammer mill is provided, whose outlet side is associated with a fan for the promotion of air through the system and for the promotion of the crushed Guts.
  • a moistening device between the hammer mill and the fan. With the help of a fine water mist is to be sprayed, which significantly reduces the dust development of the processed Guts.
  • the pellets produced can be gasified for power generation.
  • a device is in the utility model DE 20 2008 016 119 U1 described. This is about the production of moldings from a moldable material and in particular biomass. For this purpose, a rotating rasp drum is provided, with the help of which the biomass is crushed. In addition, there is a device designed as a press, which is acted upon by an electric motor. In addition, a conditioning device is provided, in which air, heat and moisture from the device for molding moldings is recycled.
  • the invention is based on the technical problem of further developing a mobile device of the type described above in such a way that the harvesting capacity is increased and a versatile device is made available.
  • the ground biomass is not only dried during the drying process, but additionally treated with at least one additive to mass inherent and / or non-organic binder for the subsequent pressing To make available.
  • the previously comminuted biomass can also be treated during the subsequent grinding process with the at least one additive.
  • the additive is added to the biomass during the milling and drying process, during milling or drying or during both operations.
  • drying in the context of the invention encompasses both a heating of the biomass and a more or less pronounced one Drying process by heat treatment, at least in the sense of post-drying. It is usually worked with both heat and an additional air flow.
  • the entire associated device Since the entire associated device is designed to be mobile, it can be spent to the storage of biomass. As a result, the described process can take place on site over the entire year and not only during the harvest time, and the biomass can be processed into pellets. This is done in such a way that the biomass is usually taken up and crushed and then ground and possibly dried or heated. Subsequently, the biomass thus treated is mixed with at least one additive or with several additives and conditioned and pressed to the conclusion to the moldings.
  • the moldings are designed germ-free and can be pressed with high bulk density. In the context of the invention, recourse is expressly made to stalk crops and no cereal grains are crushed and then pressed.
  • the initially comminuted and then ground biomass undergoes simultaneous conditioning during the grinding process and / or during drying by the additional introduction of the at least one additive.
  • both the temperature and the moisture content of the ground biomass are adjusted.
  • the temperature and the content of non-external binders and / or aromatic additives or general additives can be adjusted in the course of conditioning.
  • the ground biomass is thus not only dried, as is generally known and is required for the subsequent pressing process. Rather, the biomass is applied in the course of the drying process and / or grinding process with an additive.
  • This may be water in the simplest case.
  • the conditioning in this case provides that both the temperature of the ground and optionally dried biomass during the drying process and its moisture can be set to certain predetermined values.
  • the invention takes advantage of the fact that a certain temperature, in conjunction with a predetermined moisture content of the comminuted and ground biomass, for example, promotes the release of bulk lignin.
  • lignin is a phenolic macromolecule which, as a solid substance, is incorporated into a plant cell wall and causes lignification of the plant cell (lignification).
  • lignification usually, about 20 to 30% by weight of the dry matter of woody plants consists of lignins.
  • lignins are responsible for the strength of plant tissues as support material and hardened polymer, it is important in the pressing process following the grinding and drying process to release the lignin as comprehensively as possible in order to be able to subsequently compress it To use the ground and dried biomass of this lignin as a quasi-natural binder.
  • the invention proposes a conditioning during the grinding and possibly drying process in such a way that the ground biomass (by the drying or heating) to a moisture content in the range of about 5 wt .-% to 20 wt .-% , in particular 5 wt .-% to 15 wt .-% and preferably about 10 wt .-% is brought and at the same time be brought to temperatures of regularly above 100 ° C.
  • the ground and optionally dried biomass can be processed with lower energy expenditure in the subsequent pressing process.
  • the biomass processed in this way shows a relatively plastic behavior, so that in the subsequent pressing process the individual grinding grains or particles are reliably connected to one another.
  • the connection of the individual grinding grains takes place in practically two ways.
  • the pressing process causes the lignin present in the individual grinding grains to be released immediately as a suitable binder for the mass, thereby caking the individual mass grains. Because during the pressing process it comes as it were to plasticize the lignin and thus its desired binding effect. Secondly, the cohesion of the mass grains is reinforced by the fact that they hooked together or felted together due to their plastic character.
  • the biomass grains or mass grains in the range of less than 10 mm, preferably less than 5 millimeters, and in particular between 1 and 3 millimeters.
  • the relevant additive can be supplied via one or more injection nozzles of a conditioning chamber and / or a grinding plant.
  • the described and set in the course of conditioning process parameters can be monitored with one or more sensors. These sensors can pass their values to a central control unit for function monitoring. Depending on the measured values recorded with the aid of the sensors, the central control unit then ensures that, for example, the conditioning chamber is subjected to regulation in such a way that the biomass contained therein has the desired and previously indicated temperature. In addition, the control unit may provide for the previously mentioned moisture content. This process can also take place in the sense of a regulation, for example, if the moisture content is too low, the control unit acts on the one or more injection nozzles within the conditioning chamber and / or within the grinding chamber in such a way that the ground biomass contained therein is moistened.
  • sensors can be realized, for example, to monitor the flow rate of biomass, determining the consumption of primary energy or generally to the temperature and / or function monitoring.
