The drum is rotatably mounted on in each case a tube (3, 3') serving as a hollow axle. Both the loading and unloading of the poultry feathers and the feeding in of hot air for drying and cooling air for cooling the feathers take place via these tubes 3, 3'. The drum jacket and preferably also the end walls of the drum (1) are designed as screens (23, 24). The predominantly radial through-flow of the drum permits efficient drying, cooling and dedusting of the feathers in one and the same machine. <IMAGE>

Description

Die Erfindung betrifft eine Maschine der im Oberbegriff des Anspruches 1 angegebenen Art.The invention relates to a machine of the type specified in the preamble of claim 1.

Eine derartige Maschine ist aus der DE-AS 1 225 596 bekannt. Sie dient zum Kühlen der bereits getrockneten, noch heißen Federn, die mittels eines Gebläses angesaugt und durch eines der als Hohlachse dienenden Rohre in die Trommel geblasen werden. Nach Umschaltung auf der Saugseite wird mittels des gleichen Gebläses Kühlluft in die Trommel gedrückt. Die Kühlluft entweicht durch eine Siebeinrichtung, die in der gleichen Stirnwand der Trommel angeordnet ist, in die auch der Kühllufteinlaß mündet. Die gekühlten Federn werden über das andere als Hohlachse dienende Rohr mit Hilfe eines weiteren Gebläses abgesaugt. Nachteilig ist die ungünstige Kühlluftführung, die eine lange Kühlzeit bedingt, sowie der Umstand, daß die Geflügelfedern sowohl zum Beladen als auch zum Entladen durch jeweils ein Gebläse hindurchgefördert und daher teilweise beschädigt werden.Such a machine is known from DE-AS 1 225 596. It is used to cool the already dried, still hot springs, which are sucked in by means of a blower and blown into the drum through one of the tubes that serve as the hollow axis. After switching on the suction side, cooling air is pressed into the drum using the same fan. The cooling air escapes through a screening device which is arranged in the same end wall of the drum into which the cooling air inlet also opens. The cooled springs are sucked off via the other tube serving as the hollow axis with the aid of a further blower. Disadvantages are the unfavorable cooling air flow, which requires a long cooling time, and the fact that the poultry springs are conveyed through a fan both for loading and unloading and are therefore partially damaged.

Aus der DE-PS 659 482 ist ein Behälter zum Trocknen von Geflügelfedern bekannt, der mittels eines Dampfmantels beheizt wird. Die Federn werden währenddessen durch ein Rührwerk aufgewirbelt, hierdurch aber auch teilweise beschädigt.From DE-PS 659 482 a container for drying poultry feathers is known, which is heated by means of a steam jacket. In the meantime, the springs are whirled up by an agitator, but this also partially damages them.

Aus der EP 0 181 270 A1 ist eine Maschine zum Trocknen von Geflügelfedern bekannt, die aus einer sich in einem luftdichten Gehäuse drehenden Trommel mit einem als Sieb ausgebildeten Trommelmantel besteht, der von unten nach oben von Heißluft durchströmt wird. Die durchgehende Trommelwelle ist hohl ausgebildet und dient als Leitung zum Besprühen der Federn mit bestimmten Wirkstoffen. Hierdurch ist das Be- und Entladen der Trommel erschwert, da mindestens eine der Trommelstirnwände mit einer zusätzlichen, diesem Zweck dienenden Öffnung versehen werden muß. Außerdem ist auch bei dieser Maschine die Luftführung nicht besonders günstig.A machine for drying poultry feathers is known from EP 0 181 270 A1, which consists of a drum rotating in an airtight housing with a drum casing designed as a sieve, through which hot air flows from bottom to top. The continuous drum shaft is hollow and serves as a line for spraying the springs with certain active ingredients. This makes loading and unloading the drum difficult, since at least one of the drum end walls must be provided with an additional opening serving this purpose. In addition, the air flow is not particularly favorable with this machine either.

Alle bekannten Maschinen sind also für nur einen Behandlungsschritt ausgelegt. Die Behandlung von Geflügelfedern oder dergleichen umfaßt indessen das Waschen, das Desinfizieren, das Trocknen, das Kühlen und das Entstauben der Federn. Zum Waschen dient eine spezielle Waschmaschine. Die nachfolgenden Behandlungsschritte erfordern derzeit drei verschiedene Vorrichtungen bzw. Maschinen, nämlich eine Maschine zum Desinfizieren und Trocknen der gewaschenen Federn, ein vorgeschaltetes Silo, da das Fassungsvermögen der Trockenmaschine nur etwa ein Drittel der Waschmaschinenkapazität beträgt, sowie eine Maschine zum Kühlen und Entstauben. Diese drei Einheiten haben naturgemäß einen erheblichen Platzbedarf.All known machines are therefore designed for only one treatment step. Treatment of poultry feathers or the like, however, includes washing, disinfecting, drying, cooling and dusting the feathers. A special washing machine is used for washing. The subsequent treatment steps currently require three different devices or machines, namely a machine for disinfecting and drying the washed feathers, an upstream silo, since the capacity of the drying machine is only about a third of the washing machine capacity, and a machine for cooling and dusting. These three units naturally take up a lot of space.

Der Erfindung liegt die Aufgabe zugrunde, diesen Platzbedarf zu vermindern und hierzu eine Maschine der einleitend angegebenen Gattung so ausbilden, daß sie nicht nur durch eine verbesserte Luftführung die Behandlung einer wesentlich größeren Federmenge gestattet (und damit eine vorgeschaltetes Silo entbehrlich macht) sondern auch die schonende Vornahme aller vorgenannten Behandlungsvorgänge ermöglicht.The invention has for its object to reduce this space requirement and to this end design a machine of the type specified in the introduction such that it not only allows the treatment of a substantially larger amount of spring (and thus makes an upstream silo dispensable) by improved air guidance, but also the gentle one All of the aforementioned treatment processes can be carried out.

Hingegen ist bei der Maschine nach der Erfindung die genannte Aufgabe dadurch gelöst, daß die Trommel von einem luftdichten Gehäuse umgeben ist, das mit der Saugseite eines Gebläses in Verbindung steht und eine verschließbare Lufteintrittsöffnung hat, daß der Trommelmantel als Sieb ausgebildet ist, und daß an eines der Rohre über ein Schaltorgan ein Heizregister zur Erzeugung von Warmluft angeschlossen ist.On the other hand, in the machine according to the invention the above object is achieved in that the drum is surrounded by an airtight housing which is connected to the suction side of a blower and has a closable air inlet opening, that the drum jacket is designed as a sieve, and that one of the pipes is connected to a heating register for generating warm air via a switching element.

Durch diese Ausbildung wird eine sehr hohe Trocknungskapazität und eine ebenso hohe Kühlkapazität erzielt, da die Warmluft bzw. (nach Umschaltung) die Kaltluft praktisch alle Teile des Trommelinneren erreicht und umspült, weil der Luftstrom sich ausgehend von der Trommelachse im wesentlichen radial ausbreitet.This design achieves a very high drying capacity and an equally high cooling capacity, since the warm air or (after switching) the cold air reaches and flushes practically all parts of the inside of the drum, because the air flow spreads radially from the drum axis.

Eine weitere Verbesserung der Luftführung wird durch die Ausbildung gemäß Anspruch 2 erreicht.A further improvement of the air flow is achieved by the training according to claim 2.

Das Merkmal des Anspruches 3 verbessert die Durchmischung der Geflügelfedern und verkürzt damit die Behandlungszeit.The feature of claim 3 improves the mixing of the poultry feathers and thus shortens the treatment time.

Die Ansprüche 4, 5, 8 und 9 beziehen sich aus konstruktiv bevorzugte Ausgestaltungen der Luftführung außerhalb der Trommel bzw. des Gehäuses.The claims 4, 5, 8 and 9 relate to structurally preferred embodiments of the air duct outside the drum or the housing.

Durch die in den Ansprüchen 6 und 7 angegebenen Merkmale wird einerseits der Entladevorgang verbessert, andererseits eine weitgehende Selbstreinigung des den Trommelmantel bildenden Siebes erreicht und schließlich eine große Zugangsöffnung zur Inspektion und gegebenenfalls zum Auswechseln der Siebe geschaffen.On the one hand, the unloading process is improved by the features specified in claims 6 and 7, on the other hand extensive self-cleaning of the sieve forming the drum jacket is achieved and finally a large access opening for inspection and, if necessary, for replacing the sieves is created.

Die Ausführungsform nach Anspruch 10 beschreibt einen Trommelantrieb, der es ermöglicht, die Trommel trotz ihrer im allgmeinen beträchtlichen Größe verhältnismäßig leicht auszubilden, ohne daß die dadurch zwangsläufig entstehende Verwindungsempfindlichkeit sich nachteilig bemerkbar macht.The embodiment according to claim 10 describes a drum drive which makes it possible to make the drum relatively light in spite of its generally considerable size, without this being necessary the resulting twist sensitivity is noticeably noticeable.

Ein Ausführungsbeispiel der Maschine nach der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend näher beschrieben. Es zeigt:

einen Querschnitt.
An embodiment of the machine according to the invention is shown in the drawing and will be described in more detail below. It shows:
Figure 1
a longitudinal section
and
Figure 2
a cross section.

Die Trommel 1 ist über Büchsen 2 auf feststehenden, als Hohlachse dienenden Rohren 3 und 3ʹ drehbar gelagert. Die Rohre 3, 3ʹ ruhen auf Böcken 4. Die Trommel 1 ist über einen Elektromotor 8 antreibbar, der auf dem in Figur 1 rechts befindlichen Bock 4 angeordnet ist und über ein Riemengetriebe eine ebenfalls auf den Böcken 4 gelagerte, gemeinsame Antriebswelle 7 antreibt, die ihrerseits über Treibriemen zwei Riemenscheiben 5 in Drehung versetzt, die drehfest mit den Büchsen 2 und mithin auch mit der Trommel 1 verbunden sind. Diese Antriebskonstruktion vermeidet Verwindungen und unsymmetrische Belastungen der Trommel, die im Regelfall einen erheblichen Durchmesser (beispielsweise bis zu 4 Meter) hat.The drum 1 is rotatably mounted on bushes 2 on fixed tubes 3 and 3 'serving as the hollow axis. The tubes 3, 3ʹ rest on trestles 4. The drum 1 can be driven by an electric motor 8 which is arranged on the trestle 4 on the right in FIG. 1 and drives a common drive shaft 7, which is also mounted on the trestles 4, and which drives in turn, two belt pulleys 5 are set in rotation via drive belts, which are connected in a rotationally fixed manner to the bushes 2 and consequently also to the drum 1. This drive construction avoids torsion and asymmetrical loads on the drum, which usually has a considerable diameter (for example up to 4 meters).

Die Trommel 1 befindet sich in einem im wesentlichen luftdichten Gehäuse 6, das um einen gewissen Winkel schwenkbar um die durch die Rohre 3 und 3ʹ gebildete Achse gelagert ist. Im Ausführungsbeispiel ist das Gehäuse 6 hierzu über Lagerbüchsen zwischen den Trommelstirnwänden und den Riemenscheiben 5 auf den Büchsen 2 gelagert. Das Gehäuse 6 hat einen Gehäuseboden 9, der über Arbeitszylinder 10 absenkbar ist. Die Arbeitszylinder 10 stützen sich gegen die Böcke 4 ab. Beim Verschwenken des Gehäuses 6 bleibt dessen Boden 9 also ortsfest.The drum 1 is located in an essentially airtight housing 6, which is pivotable about a certain angle about the axis formed by the tubes 3 and 3ʹ. In the exemplary embodiment, the housing 6 is mounted on the bushes 2 via bearing bushes between the drum end walls and the pulleys 5. The housing 6 has a housing base 9 which can be lowered via the working cylinder 10. The working cylinders 10 are supported against the trestles 4. When the housing 6 is pivoted, its base 9 thus remains stationary.

Aus dem Gehäuseboden 9 mündet ein Anschluß 11 aus, der über ein Rohr mit der Saugseite eines Gebläses 12 verbunden ist, an dessen Druckseite ein Fortluftrohr 13 mit einer Abzweigung 14 für Umluft angeschlossen ist. Die Umluft strömt über einen Filter 15 und ein Umluftrohr 16 einem Heizregister 17 zu, das zur Zumischung von Frischluft mit einer verstellbaren Klappe 18 ausgerüstet ist.From the housing bottom 9 a connection 11 opens out, which is connected via a tube to the suction side of a blower 12, on the pressure side of which an exhaust air tube 13 is connected to a branch 14 for circulating air. The circulating air flows through a filter 15 and a circulating air pipe 16 to a heating register 17 which is equipped with an adjustable flap 18 for adding fresh air.

Die Rohre 3 bzw . 3ʹ sind an ihren außenseitigen Enden durch Drehschieber 19 bzw. 29 abgeschlossen. Über den Drehschieber 19 kann das Rohr 3 wahlweise mit dem Heizregister 17 oder einem Kühlluftrohr 22 verbunden werden. Über den Drehschieber 29 kann das Rohr 3ʹ wahlweise mit einem Beladerohr 20 oder einem Entladerohr 21 verbunden werden. Beide Rohre 3, bzw. 3ʹ stehen über stirnseitige Mündungen 26 mit dem Inneren der Trommel 1 in Verbindung. Zusätzlich sind durch das Rohr 3 zwei nur schematisch angedeutete Leitungen 30, 31 in das Innere der Trommel 1 geführt und enden in Düsen 27 bzw. 28.The pipes 3 and. 3ʹ are completed at their outer ends by rotary valves 19 and 29. Via the rotary valve 19, the tube 3 can be connected either to the heating register 17 or to a cooling air tube 22. Via the rotary valve 29, the tube 3ʹ can optionally be connected to a loading tube 20 or an unloading tube 21. Both tubes 3 and 3ʹ are connected to the inside of the drum 1 via end openings 26. In addition, two pipes 30, 31, only indicated schematically, are led through the pipe 3 into the interior of the drum 1 and end in nozzles 27 and 28, respectively.

Der Mantel der Trommel 1 wird durch Mantelsiebe 23 gebildet. Die Stirnwände der Trommel 1 werden überwiegend von Stirnwandsieben 24 gebildet. In die Trommel 1 sind sich über ihre volle Breite erstreckende, radial orientierte Mitnehmerflächen 25 eingebaut, die von Trommelumfang bis etwa in Höhe des halben Trommelradius reichen.The jacket of the drum 1 is formed by jacket screens 23. The end walls of the drum 1 are predominantly formed by end wall screens 24. Radially oriented driver surfaces 25, which extend over their full width and extend from the drum circumference to approximately half the drum radius, are installed in the drum 1.

Die Maschine arbeitet wie folgt: Der Elektromotor 8 und das Gebläse 12 werden eingeschaltet und der Drehschieber 29 stellt über dar Rohr 3ʹ die Verbindung zwischen dem Beladerohr 23 und der Trommel 1 her, um die nassen Geflügelfedern anzusaugen. Nach dem Beladen wird der Drehschieber 29 geschlossen und der Drehschieber 19 verbindet nun die Trommel 1 dem Heizregister 17, so daß über das Rohr 3 Warmluft angesaugt und über das Gebläse 12 abgesaugt wird. Währenddessen können über die Düsen 28 ein Desinfektionsmittel und über die Düsen 29 weitere Wirkstoffe eingesprüht werden. Nach dem Trocknen der Federn wird der Drehschieber 19 umgestellt und verbindet nun die Trommel 1 mit dem Kühlluftrohr 22 zum Kühlen der Federn.The machine works as follows: The electric motor 8 and the blower 12 are switched on and the rotary slide valve 29 establishes the connection between the loading tube 23 and the drum 1 via tube 3ʹ in order to suck in the wet poultry springs. After loading, the rotary valve 29 is closed and the rotary valve 19 now connects the drum 1 to the heating register 17, so that warm air is sucked in through the pipe 3 and sucked out through the blower 12. In the meantime, a disinfectant can be sprayed in via the nozzles 28 and further active substances can be sprayed in via the nozzles 29. After the springs have dried, the rotary valve 19 is switched over and now connects the drum 1 to the cooling air pipe 22 for cooling the springs.

Zum Entladen wird der Drehschieber 19 geschlossen, der Drehschieber 29 in die das Rohr 3ʹ mit dem Entladerohr 21 verbindende Stellung gebracht und das Gebläse 12 abgeschaltet. Die Geflügelfedern können nun mittels einer Absackanlage aus dem Inneren der Trommel 1 abgesaugt werden. Hierzu wird der Gehäuseboden 9 durch die Arbeitszylinder 10 abgesenkt. Die Luft strömt dann in umgekehrter Richtung durch die Siebe und befreit diese von anhaftenden Geflügelfedern.For unloading, the rotary valve 19 is closed, the rotary valve 29 is brought into the position connecting the tube 3 'with the unloading tube 21 and the fan 12 is switched off. The poultry feathers can now be sucked out of the inside of the drum 1 by means of a bagging system. For this purpose, the housing base 9 is lowered by the working cylinder 10. The air then flows through the sieves in the opposite direction and frees them from adhering poultry feathers.

Bei abgesenktem Gehäuseboden 9 kann das Gehäuse 6 in eine beliebige Winkelstellung geschwenkt werden. Die damit freiwerdende, große Öffnung in dem Gehäuse erlaubt eine bequeme Inspektion, gegebenenfalls auch eine Reinigung oder einen Austausch der Siebe.When the housing base 9 is lowered, the housing 6 can be pivoted into any angular position. The large opening in the housing that is freed up in this way allows convenient inspection, possibly also cleaning or replacement of the screens.
