Description

Verfahren zum Trocknen von Geflügeldung Gegenstand der Erfindung ist ein Verfahren zur Trocknung von Geflügeldung, besonders Dung vom Haushuhn, durch Mischen des Dungs mit Adsorptionsmitteln undTrocknen der so erhaltenen Mischung.Method for drying poultry manure is the subject of the invention a method of drying poultry manure, especially domestic chicken manure Mixing the manure with adsorbents and drying the mixture thus obtained.

Die Beimischung von Adsorptionsmitteln beim Trocknen von Dung ist bekannt. Sie hat sich als notwendig erwiesen, weil die klumpige und klebrige Konsistenz des rohen Dungs mit seinem Gehalt von etwa 70 bis 80% H20 eine Trocknung nahezu unmöglich macht, bei der ein homogenes Endprodukt mit gleichmäßig durch die ganze Masse verteiltem Feuchtigkeitsgehalt einigermaßen garantiert werden kann.The admixture of adsorbents when drying manure is known. It has been found necessary because of the lumpy and sticky consistency of the raw manure with its content of about 70 to 80% H20 is almost completely dry makes impossible to produce a homogeneous end product with evenly through the whole Mass distributed moisture content can be reasonably guaranteed.

Phosphathaltige Zusätze, Gips, saure Salze und schließlich auch Törfmull sind bekanntgeworden, Zusätze, die entweder verhältnismäßig teuer sind, schädliche Nebenwirkungen zeigen, in verhältnismäßig großer Menge beigefügt werden müssen und so die Dungkonzentration verringern oder so hohe Trocknungstemperaturen verlangen, daß dadurch die nützlichen Bakterienkulturen im Rohdung zumindest stark gefährdet werden. Außerdem ist bisher keines dieser Adsorptionsmittel in der Lage gewesen, dem Dung seinen unangenehmen Geruch zu nehmen.Phosphate additives, gypsum, acidic salts and finally also Törfmull have become known to be harmful additives that are either relatively expensive Side effects show, must be added in relatively large quantities and so reduce the manure concentration or require such high drying temperatures, that thereby the useful bacterial cultures in the raw manure is at least severely endangered will. In addition, none of these adsorbents has yet been able to to take away its unpleasant smell from the dung.

Alle diese Nachteile treten erfindungsgemäß nicht auf, wenn man pulverförmige Adsorptionskohle, z. B. Holzkohle, in einer Menge von 5 bis 30, vorzugsweise 10 bis 20%, bei einer Trocknungstemperatur zwischen 40 und 45° verwendet. Bei der Mischung mit Adsorptionskohle erreicht man buchstäblich innerhalb weniger Minuten den totalen Zerfall eines so klumpigen und klebrigen Produkts, wie Hühnermist, in ein flockiges, fast pulverartiges Material, das schnell und leicht bei maximal 45° auf ein Endprodukt von ganz geringem Feuchtigkeitsgehalt getrocknet werden kann. ohne daß seine wertvollsten Bestandteile, die natürlichen Bakterienkulturen, dabei angegriffen werden. Und außerdem ist diese Mischung nahezu geruchlos, was sie zu einem bevorzugten Düngemittel im Hausgebrauch (für Topfpflanzen usw.) macht.According to the invention, none of these disadvantages occur when powdery Adsorption carbon, e.g. B. charcoal, in an amount of 5 to 30, preferably 10 up to 20%, used at a drying temperature between 40 and 45 °. In the mix with adsorption charcoal you can literally reach the total within a few minutes Disintegration of a product as lumpy and sticky as chicken manure into a flaky, almost powder-like material that quickly and easily at a maximum of 45 ° on an end product can be dried with a very low moisture content. without its most valuable Components, the natural bacterial cultures, are attacked in the process. And also this mixture is almost odorless, making it a preferred fertilizer in the world Household use (for potted plants, etc.).

Der Misch- und Trocknungsvorgang ist denkbar einfach.The mixing and drying process is very easy.

100 kg Hühnermist werden in einer geeigneten Mischvorrichtung 9 kg feingemahlener Holzkohle beigemengt. Nach knapp 2 Minuten erhält man ein flockiges Material, das auf Trockenplatten ausgebreitet und in einem Trockenschrank bei etwa 40° so lange gehalten wird, bis der Feuchtigkeitsgehalt auf ungefähr 5 % gesunken ist. Man bekommt dann ein leicht rinnendes, nahezu geruchloses Pulver, dem man für besondere Zwecke andere Dünge- oder Nährsalze, z. B. Superphosphate (aber auch Kalium- oder Ammoniumsulfat, Salpeter- oder Phosphorsäure), in entsprechender Menge beimischen kann, wenn man das Endprodukt mit Stickstoff anreichern oder Stickstoffverluste während der Lagerung vermeiden will. Schließlich läßt sich das Endprodukt in Tabletten- oder ähnliche Formen pressen, um es z. B. für den Kleingebrauch in handliche Form zu bringen.100 kg chicken manure becomes 9 kg in a suitable mixer finely ground charcoal added. After just under 2 minutes you get a flaky one Material spread out on drying plates and in a drying cabinet at about 40 ° is held until the moisture content has dropped to about 5% is. You then get a slightly flowing, almost odorless powder, which you can use for special purposes other fertilizer or nutrient salts, e.g. B. superphosphates (but also potassium or ammonium sulfate, nitric or phosphoric acid), add the appropriate amount can if you enrich the end product with nitrogen or nitrogen losses want to avoid during storage. Finally, the end product can be converted into tablets or press similar shapes to make it z. B. for small use in a handy form bring to.
