Abstract

The invention relates to ground straw as a construction element or additive for industrial products which are to be disposed of at least predominantly by biological degradation. It serves for the effective reutilisation of renewable raw materials which are obtained as by-product from plant production, for the manufacture of auxiliaries, additives and construction materials which are able if required to undergo ready biodegradation. Ground straw of this kind, in the form of particles containing, in particular, lignin and cellulose, with a length > 0.3 mm and < 30 mm and a width/thickness < 2 mm is produced by the operations of chopping the sections of straw to a length of > 20 mm < 80 mm, followed by grinding and, if desired, by an aftertreatment which involves screening out certain fractions, and mixing. The agricultural crop plants used for manufacturing this ground straw may comprise the dried stalks or stems of, in particular, the cereal plants wheat, rye, barley, oats, maize, triticale, rice and millet, of the oil-bearing fruits oilseed rape, linseed, soya and sunflower, or of the pulse crops peas, beans and lentils.

Description

Die Erfindung betrifft ein Strohmehl als Konstruktionselement oder Zuschlagstoff für zumindest überwiegend durch biologischen Abbau zu entsorgende industrielle Produkte. Sie dient der effektiven Verwertung von in der Pflanzenproduktion als Abprodukt anfallenden, nachwachsenden Rohstoffe zur Erzeugung im Bedarfsfalle biologisch leicht abbaubarer Hilfs-, Zuschlag- und Konstruktionswerkstoffe.The invention relates to a straw meal as Construction element or aggregate for at least mainly to be disposed of by biodegradation industrial products. It is used for effective recycling of waste produced in plant production, renewable raw materials for production when needed biodegradable auxiliary, aggregate and Construction materials.

Bei der Erzeugung pflanzlicher Produkte in der Landwirtschaft werden in der Regel nur Teile der landwirtschaftlichen Nutzpflanzen als Produkt angesehen und einer Verwertung zugeführt. Bei diesen Feldfrüchten handelt es sich in der Regel entweder um die Samen der Pflanzen oder um bestimmte Speicherkörper im Stengel oder Wurzelbereich. Während bei letzteren Pflanzen mit der Ausbildung der "Feldfrucht" als zumeist unterirdischen, dem Überwintern der Pflanzen dienenden Reservoiren, wie beispielsweise Kartoffelknollen, Rüben oder Zwiebel, alle anderen Pflanzenteile wie Laub und Stengel weitgehend resorbiert werden, bilden die Stengel der Pflanzen, bei denen Samen als Produkt geerntet werden, beispielsweise die Getreidehalme, ein als Abfallprodukt betrachtetes Stroh mit einem Anteil von 40 bis 70% der insgesamt gewachsenen Trockenmasse.When producing vegetable products in the Agriculture is usually only part of the agricultural crops viewed as a product and recycled. Trade in these crops it is usually either the seeds of the plants or to certain storage bodies in the stem or Root area. While with the latter plants with the Training of the "field crop" as mostly underground, the Overwintering the plant-serving reservoirs, such as for example potato tubers, beets or onions, all other parts of plants such as leaves and stems largely are resorbed, form the stems of the plants, at where seeds are harvested as a product, such as the Straws of straw, a straw considered as a waste product with a share of 40 to 70% of the total grown Dry matter.

Von diesem Stroh kann nur ein geringer Anteil in der Landwirtschaft als Futtermittelbeimischung oder Einstreu verwendet werden. Weitere Anteile werden zum Teil als Mittel zur Verbesserung der Bodengar´ verwendet.Only a small proportion of this straw can be found in the Agriculture as a feed additive or bedding be used. Other shares are partly called Means used to improve the bottom cooking.

Trotz des relativ hohen Energiegehaltes und der beachtlichen mechanischen Stabilität hat sich bisher die industrielle Verwertung dieses nachwachsenden Rohstoffes nicht durchsetzen können. Die Ursachen hierfür sind vielfältig. Der im allgemeinen hohe Gehalt an Lignin und Pentosanen in Größenordnungen von 30 bis 50% steht der Verarbeitung zu Cellulose entgegen. Bei der Verarbeitung von gehäckseltem oder geschnittenen Stroh als Ersatz von Holzhackschnitzel in der Herstellung von Spanplatten erweist sich als hinderlich, daß die Oberfläche insbesondere von Getreidestroh eine natürliche wasserabweisende Imprägnierung aufweist, die beispielsweise bei der Herstellung von Strohdächern genutzt wird. Diese wasserabweisende Wirkung erschwert bei der Verarbeitung von Strohhäcksel die Einbindung derselben durch den Klebstoff. Aus diesem Grunde wird für die Herstellung von plattenförmigen Elementen unter Verwendung pflanzlicher Abfallstoffe entweder auf die bei der Gewinnung bestimmter Rohstoffe, wie beispielsweise in der DE OS 25 25 376 beschrieben, bei der Furfuralgewinnung anfallende, bereits aufgeschlossene Pflanzenfasern zurückgegriffen oder man nutzt die beim Pressen langfaserigen Strohs auftretende "Verfilzung" der Halme zum Ausgleich der verringerten Klebkräfte aus, wie es in der DE OS 36 02 381 beschrieben wird. Während bei dem erstbeschriebenen Verfahren der Anteil des verarbeitbaren Strohs durch den Bedarf an dem aus dem Aufschließungsprozeß benötigen Produkt beschränkt ist, schränkt im zweiten Falle die grobe Struktur des Erzeugnisses und die schlechte Handhabbarkeit des Ausgangsmaterials dessen Verwendbarkeit ein.Despite the relatively high energy content and the considerable mechanical stability has so far been industrial Not using this renewable raw material can enforce. The causes for this are manifold. The generally high content of lignin and pentosans in  Processing is of the order of 30 to 50% Against cellulose. When processing chopped or cut straw as a substitute for wood chips in the production of chipboard proves to be hinders that the surface in particular from Cereal straw a natural water-repellent Has impregnation, for example in the Production of thatched roofs is used. These water-repellent effect difficult when processing Chopping straw incorporating the same with the adhesive. For this reason, for the production of plate-shaped elements using vegetable Waste materials either on those specific to the extraction Raw materials, such as in DE OS 25 25 376 described in the furfural extraction, already open-ended plant fibers or one uses the long-fiber straw that occurs when pressing "Matting" of the stalks to compensate for the reduced Adhesive forces from, as described in DE OS 36 02 381 becomes. While in the first described method of Proportion of straw that can be processed due to the need for product need limited from the disintegration process limits the rough structure of the Product and the poor manageability of the Starting material its usability.

Aufgabe der Erfindung ist es deshalb, ein technisch verwertbares Zwischenprodukt für die Verwertung von Stroh als Stütz- und Füllmaterial bei der Produktion insbesondere von Massengütern bereitzustellen. Task of The invention is therefore a technically usable one Intermediate product for the use of straw as a support and Filling material in the production of To provide bulk goods.

Als ein solches Zwischenprodukt ist ein Strohmehl gemäß Erfindungsanspruch anzusehen.As such an intermediate product is a straw meal according to To view invention claim.

Ein erfindungsgemäßes Strohmehl kann folgendermaßen erzeugt werden:
Ausgangsprodukt für die Strohmehlfertigung sind getrocknete Halme oder Stengel insbesondere der Getreidepflanzen Weizen, Roggen, Gerste, Hafer, Mais, Triticale, Reis und Hirse, der Ölfrüchte Raps, Lein, Soja und Sonnenblumen und der Hülsenfrüchte Erbsen, Bohnen und Linsen.A straw meal according to the invention can be produced as follows:
The starting product for straw meal production is dried stalks or stalks, in particular of the cereals wheat, rye, barley, oats, maize, triticale, rice and millet, oilseed rape, linseed, soy and sunflowers and legumes peas, beans and lentils.

Das bei der Ernte der Feldfrüchte anfallende Stroh wird mit einer Restfeuchte von unter 16% geerntet und der stationären Weiterverarbeitung zugeführt. Der Transport ist je nach eingesetzter Erntetechnik in Form von Ballen oder als Strohhäcksel möglich. Beim Transport in Ballenform steht eine Einsparung von Transportraum dem erhöhten Aufwand der Ballenbildung und -auflösung gegenüber. Bei der Anlieferung in Form von gerollten oder gepreßten Ballen wird das Stroh in der ersten Produktionsstufe des stationären Prozesses gehäckselt. Die Schnittlänge der Strohpartikel sollte nach dem Häckselvorgang zwischen 30 und 80 mm liegen.The straw that is produced during the harvest of the crop is included a residual moisture of less than 16% and the stationary further processing supplied. The transportation is depending on the harvesting technology used in the form of bales or possible as a straw chop. When transported in bale form there is a saving of transport space to the increased Compared to the effort involved in bale formation and disintegration. In the Delivery in the form of rolled or pressed bales the straw is in the first stage of production of the stationary process chopped. The cutting length of the Straw particles should be between 30 and 30 minutes after the chopping process and 80 mm.

Das gehäckselte Stroh wird, nach einer bei Überschreitung des technologisch optimalen Wassergehaltes gegebenenfalls eingeschalteten Zwischentrocknung, einem Mahlwerk zugeführt.The chopped straw is, after one when exceeded the technologically optimal water content if necessary switched on intermediate drying, a grinder fed.

Zur Erzeugung einer optimalen Struktur des Strohmehles ist insbesondere die Anwendung einer Hammermühle als rationell anzusehen.To create an optimal structure of the straw flour especially the use of a hammer mill as rational to watch.

Um ein der weiteren Verwendung angepaßtes Produkt mit einer für eine Großfertigung notwendigen gleichbleibenden Qualität zu erzeugen, wird das von der Mühle erzeugte Gemisch unterschiedlich großer Strohpartikel unter Verwendung von Sieben fraktioniert. Durch die Mischung verschiedener Siebfraktionen und von Strohmehlen aus unterschiedlichen Pflanzenmaterialien wird bedarfsweise eine weitere Anpassung des Produktes erzielt.To a product adapted for further use with a constant for a large production Generating quality becomes what the mill produces Mixture of straw particles of different sizes Using fractionated seven. Through the mix different sieve fractions and from straw flours different plant materials will be needed achieved a further adjustment of the product.

Das so erzeugte Strohmehl ist als Hilfsstoff unter anderem in der Kunststoff-, der Papier- und Verpackungs- und der Bauindustrie einsetzbar. Strohmehl ist als Hilfsstoff für Folien, Verpackungen, Textilien, Waschmittel, Klebstoffe, Farben, Poliermehl und Kohlenanzünder, als Zuschlagstoff für Kartonagen, Pappen, Papier, Tapeten, Toilettenpapier brauchbar. Weiter ist die Verwendung als konstruktives Element in Platten und Formkörpern für die Bauindustrie, für die Herstellung von Pflanzschalen und -kübeln. Letztlich ist Strohmehl direkt als Füll- und Isolierstoff in der Verpackungs- und Bauindustrie zu verwenden. Die rein organische Zusammensetzung dieses Hilfsstoffe erlaubt in vielen Fällen die Abfallbeseitigung der Produkte durch Zerkleinerung und anschließendes Kompostieren.The straw flour produced in this way is, among other things, an auxiliary in the plastic, paper and packaging and the  Construction industry can be used. Straw flour is used as an adjuvant for Foils, packaging, textiles, detergents, adhesives, Paints, polishing powder and lighter, as an additive for cardboard, cardboard, paper, wallpaper, toilet paper useful. Next is the use as a constructive Element in sheets and moldings for the construction industry, for the production of plant trays and planters. Ultimately, straw flour is used directly as a filling and insulating material to be used in the packaging and construction industries. The pure organic composition of this excipient allows in waste disposal of the products in many cases Shredding and subsequent composting.

Die Herstellung eines erfindungsgemäßen Strohmehles soll im Folgenden an Hand eines Ausführungsbeispiels erläutert werden.The production of a straw flour according to the invention is said to The following is explained using an exemplary embodiment become.

Bei der Getreideernte wird das anfallende Stroh mit einer Restfeuchte von unter 12% nach dem Mähdrusch durch einen Exakthäcksler aufgenommen, auf eine Länge von durchschnittlich 50 mm gehäckselt, in Transportfahrzeuge geblasen und der stationären Strohmehlproduktion zugeführt.During the grain harvest, the straw that comes with a Residual moisture of less than 12% after a combine Precision chopper added to a length of 50 mm chopped on average in transport vehicles blown and fed to stationary straw flour production.

Das gehäckselte Stroh wird, nach einer Zwischentrocknung auf eine Restfeuchte, einem Mahlwerk in Form einer hartmetallbesetzten Hammermühle zugeführt und auf eine durchschnittliche Teillänge von 10 mm gemahlen.The chopped straw is, after an intermediate drying to a residual moisture, a grinder in the form of a carbide-tipped hammer mill fed and on a average part length of 10 mm ground.

Das Mahlprodukt als Gemisch unterschiedlich großer Strohpartikel wird unter Verwendung von Sieben mit 3 und 8 mm fraktioniert.The ground product as a mixture of different sizes Straw particles are made using sieves with 3 and 8 mm fractionated.
