Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung von Dünge-Depotgefäßen in Form von Pellets, insbesondere herausgebildet aus Mist, Kompost und anderen biologischen Rohstoffen.The The invention relates to a method and an apparatus for the production of fertilizer depot vessels in the form of pellets, especially formed from manure, compost and others biological raw materials.
Die Herstellung von Pellets, d. h. von Pressagglomeraten für verschiedene Anwendungen in der Landwirtschaft, insbesondere für Futtermittel, ist seit langem bekannt. Die Zusammenballung von pulverförmigen mineralischen Düngemitteln durch Roll- und Pressagglomeration zu Körpern gewünschten Durchmessers ist ebenfalls bekannt. Mittels dieser bekannten Verfahren war es bisher nicht möglich, Mist oder feuchten Kompost zu pelletieren, da die zu hohe Feuchtigkeit >35 % eine Extrusion nicht zulässt und auch langfaserige Bestandteile vor dem eigentlichen Pelletieren zerkleinert werden müssen.The Production of pellets, d. H. of press agglomerates for different Applications in agriculture, in particular for animal feed, has been known for a long time. The aggregation of powdered mineral fertilizers by roll and press agglomeration to bodies of desired diameter is also known. By these known methods it has not been possible, crap or moist compost to pellet because the excess moisture> 35% is an extrusion does not allow and also long-fiber components before the actual pelleting must be crushed.
Nachteilig bei den bekannten Verfahren ist, dass die agglomerierten Düngemittel ihre Düngewirkung nur kurzzeitig entfalten, eine zeitliche Steuerung nicht möglich ist.adversely in the known methods is that the agglomerated fertilizer their fertilizing effect unfold only briefly, a time control is not possible.
Unter Beachtung der Nachteile des Standes der Technik ist es Aufgabe der vorliegenden Erfindung, ein Verfahren und eine Vorrichtung zur Herstellung von Dünge-Depotgefäßen in Form von Pellets zu entwickeln, insbesondere herstellbar aus Mist, Kompost und anderen biologischen Rohstoffen, mit denen die Nachteile der bekannten Lösungen weitestgehend ausgeschlossen werden.Under Attention to the disadvantages of the prior art, it is the task of present invention, a method and an apparatus for the production of fertilizer depot vessels in the form to develop from pellets, in particular from manure, compost and other biological raw materials with which the disadvantages of known solutions be largely excluded.
Erfindungsgemäß wird die Aufgabe mit den Merkmalen des Anspruchs 1 gelöst. Besondere Ausführungsformen und vorteilhafte Lösungen sind in den Unteransprüchen angegeben.According to the invention Task solved with the features of claim 1. Special embodiments and advantageous solutions are in the subclaims specified.
So wurde ein Verfahren geschaffen, mit dem Dünge-Depotgefäße herstellbar sind, dies in Ausformung eines organischen Trägermaterials, mit einem Feuchtegehalt von ca. 20 bis 35 %, das die Pelletierung ermöglicht, die Zerkleinerung langfaserigen Materials gewährleistet, die Zumischung und Einlagerung von definierten Mengen von Düngezusatzstoffen in das Trägermaterial gestattet und die Ausbildung einer Außenhaut aus organischen Stoffen ermöglicht und so die gewünschten Effekte zur zeitlichen Steuerbarkeit der Nährstoffabgabe an die Pflanzen bringt.So a procedure was created with which fertilizer depot vessels can be produced are, in the form of an organic carrier material, with a moisture content from about 20 to 35%, which allows pelleting, the comminution long-fiber Material ensures the admixture and storage of defined quantities of fertilizer additives in the carrier material allowed and the formation of an outer skin of organic matter allows and so the desired Effects on the temporal controllability of the nutrient delivery to the plants brings.
Daraus resultiert die Folge der Verfahrensstufen:
- – Mistentsaftung
- – Zuführung von Dünge-, Gleit- und Härtestoffen
- – 1. Zerkleinerungs- und Mischstufe
- – 2. Zerkleinerungs- und Mischstufe
- – Härtung der Außenhaut der Depotkörper (Pellets)
- - manure sap
- - Supply of fertilizers, lubricants and hardening substances
- - 1st crushing and mixing stage
- - 2nd crushing and mixing stage
- - hardening of the outer skin of the depot bodies (pellets)
Die erfindungsgemäße Lösung besteht in der Aggregierung der genannten Verfahrensstufen in einem Apparat mit einer durchgängigen Extrusionsschnecke, wobei die Schneidstufen zugleich als Mischstufen ausgebildet sind und in der letzten Stufe die Härtung der Pelletoberfläche durch direkte Erwärmung der Pelletiermatrizen erfolgt mit nachgeschalteter Wirbelschichttrocknung. So wird die zeitliche Steuerbarkeit des Depoteffektes ermöglicht.The inventive solution exists in the aggregation of said process steps in an apparatus with a consistent Extrusion screw, wherein the cutting stages at the same time as mixing stages are formed and in the last stage, the curing of the pellet surface by direct heating The pelleting matrices are carried out with downstream fluidized bed drying. This enables the temporal controllability of the depot effect.
