Between the tower and the edge of the drying area is a canopy clamped.
Die derart ausgeführte Trocknungsanlage lässt sich vergleichsweise preiswert und einfach herstellen. Gleichzeitig ermöglicht sie eine effektive Trocknung von Biomasse. Zu der effektiven Trocknung trägt insbesondere die einem Aufwindkraftwerk nachempfundene Struktur der Trocknungsanlage bei, bei der im Bereich der überdachten Trocknungsfläche durch Sonneneinstrahlung und/oder künstliche Beheizung eine hohe Lufttemperatur erzielt wird, durch welche im Entlüftungsturm ein Kamineffekt bewirkt wird, der wiederum für Zugluft im Bereich der Trocknungsfläche und somit für eine effektivierte Trocknung sorgt. Der Entlüftungsturm ist hierzu in einem an die Trocknungsfläche angrenzenden unteren Bereich mit Ansaugöffnungen versehen, durch die die abzuführende Luft von der Trocknungsflä che in den Entlüftungsturm eingesaugt wird. Oben ist der Entlüftungsturm offen oder zumindest mit Luftausströmöffnungen versehen.The so executed Drying plant leaves comparatively inexpensive and easy to manufacture. simultaneously allows they effectively dry biomass. To the effective drying contributes in particular the structure of the drying plant, modeled after an updraft power plant, at the covered area drying surface due to solar radiation and / or artificial heating a high Air temperature is achieved through which in the vent tower a chimney effect is effected, in turn, for drafts in the area of the drying surface and thus for an effective drying ensures. The vent tower is this in one to the drying surface adjacent lower area provided with suction through which the dissipated Air from the Trocknungsflä surface in the vent tower is sucked in. At the top, the vent tower is open or at least with air outlets Mistake.
Die Trocknungsfläche ist in besonders einfacher und preisgünstig realisierbarer Ausführung bevorzugt überdacht mit einer flexiblen Plane in Form einer textilen Zeltplane oder einer Folie, insbesondere einer Luftpolsterfolie. In bevorzugten Ausgestaltungen besteht die Überdachung aus einem transparenten Material, um Sonneneinstrahlung stark zu ermöglichen, oder alternativ aus einem dunklen, Sonnenstrahlung absorbierenden Material. Alternativ kann grundsätzlich aber auch eine selbsttragende Dachstruktur, insbesondere aus Glas oder Metall, vorgesehen sein.The drying surface is preferably roofed in a particularly simple and inexpensive realisierbarer execution with a flexible tarpaulin in the form of a textile tarpaulin or a film, in particular a bubble wrap. In preferred Embodiments consists of the roofing Made of a transparent material, strong to solar radiation enable, or alternatively from a dark, solar radiation absorbing Material. Alternatively, basically but also a self-supporting roof structure, in particular of glass or metal, be provided.
Vorteilhafterweise ist der Entlüftungsturm mit einem Biofilter zur Reinigung der ausströmenden Luft, insbesondere von Geruchsstoffen, und/oder mit einem Ventilator zur Verstärkung des Luftzuges versehen. Der Ventilator ist optional – wie bei einem Aufwindkraftwerk – auch generatorisch einsetzbar. Der Entlüftungsturm kann weiterhin mit einer Blechüberdachung mit entsprechenden Luftausströmöffnungen überdacht sein.advantageously, is the breather tower with a biofilter for cleaning the outflowing air, in particular of Odorants, and / or with a fan to reinforce the Draft provided. The fan is optional - as in the case of an updraft power plant - also as generator used. The vent tower Can continue with a sheet metal roofing Covered with appropriate air outlets be.
Die Anlage umfasst weiterhin zweckmäßigerweise eine Wendeeinrichtung, die um den Turm kreisend über die Trocknungsfläche verfahrbar ist. Die Wendeeinrichtung dient zur Umwendung der trocknenden Biomasse und somit – durch Vergrößerung der effektiven Oberfläche der Biomasse – zur weiteren Effektivierung der Trocknung. Eine kreisrunde Geometrie der Trocknungsfläche und die zentrale Position des Entlüftungsturms ermöglichen hierbei eine besonders einfache und effektive Ausführung dieser Wendeeinrichtung. Die Wendeeinrichtung umfasst zum Wenden der Biomasse zweckmäßigerweise Federzinken oder -bleche, wie sie in der Landwirtschaft beispielsweise bei Heuwendern Verwendung finden. Diese Federzinken sind beispielsweise am unteren Rand eines Gerüsts aus Metall, Holz oder dergleichen angebracht. Die Wendeeinrichtung ist vorteilhafterweise rotierbar an dem Entlüftungsturm aufgehängt. Die Wendeeinrichtung wird zweckmäßigerweise angetrieben von einem motorisch betriebenen Laufrad, das auf dem Rand der Trocknungsfläche läuft. Die Wendeeinrichtung kann auch mit Räumschildern, Leitblechen, Schaufeln oder dergleichen versehen sein.The Annex further includes expediently a turning device, which can be moved around the tower in a circle over the drying surface is. The turning device is used to reverse the drying biomass and thus - by Magnification of the effective surface biomass - for further Effectiveness of drying. A circular geometry of the drying surface and the central position of the venting tower enable this is a particularly simple and effective execution of this Turning device. The turning device comprises turning the biomass expediently Spring tines or sheets, as in agriculture, for example to be used by haymakers. These spring tines are for example at the bottom of a scaffold made of metal, wood or the like. The turning device is advantageously rotatably suspended from the vent tower. The Turning device is expediently powered by a powered impeller mounted on the Edge of the drying surface running. The turning device can also with skid plates, baffles, shovels or the like.
Die Trocknungsfläche ist vorteilhafterweise mit einer Fußbodenheizung zur Beschleunigung des Trocknungsprozesses, insbesondere im Winter, versehen. Alternativ oder zusätzlich kann aber auch eine Luftheizung, insbesondere ein Warmluftgebläse, vorgesehen sein. Zweckmäßigerweise ist unter der Trocknungsfläche, die bevorzugt aus Beton besteht, eine Wärmedämmschicht, insbesondere aus Glaswolle, PU-Schaum oder dergleichen eingezogen. Die Trocknungsfläche ist zweckmäßigerweise wannenartig mit einem erhöhten Rand ausgebildet. Im Inneren ist die Trocknungsfläche bevorzugt eben. In alternativer Ausführung ist die Trocknungsfläche trichterartig zum Entlüftungsturm hin oder nach außen hin geneigt.The drying surface is advantageously with a floor heating for acceleration the drying process, especially in winter, provided. alternative or additionally but can also be an air heater, in particular a hot air blower, provided be.

In einfachster Ausführung erfolgt die Beladung und Entladung der Trocknungsanlage diskontinuierlich mit einem mobilen Ladegerät, insbesondere einem Bagger oder Rad- bzw. Frontlader. Die Überdachung wird hierzu temporär und zumindest teilweise entfernt. In alternativen Ausführungen ist die Trocknungsanlage mit einer Beladeeinrichtung und/oder einer Entladeeinrichtung versehen. Als Entladeeinrichtung findet insbesondere eine motorisch betriebene Förderschnecke Anwendung, die am Boden der Trocknungsfläche radial zum Entlüftungsturm verläuft. Die Förderschnecke verläuft insbesondere ganz oder teilweise versenkt in einer Vertiefung des Bodens der Trocknungsfläche. Als Beladeeinrichtung dient insbesondere ein Förderband, das bevorzugt wiederum etwa radial zum Entlüftungsturm und oberhalb der Wendeeinrichtung verläuft. Die Verteilung der eingeladenen feuchten Biomasse auf der Trocknungsfläche, und die Beförderung der getrockneten Biomasse zur Entladeeinrichtung erfolgt hierbei automatisch über die Wendeeinrichtung.In the simplest version, the loading and unloading of the drying plant is discontinuous with a mobile charger, in particular an excavator or wheel or front loader. The roofing is temporarily and at least partially removed. In alternative embodiments, the drying plant is provided with a loading device and / or an unloading device. As unloading finds in particular a motor powered auger application that extends radially to the vent tower at the bottom of the drying surface.
