A device for the distribution of air from the ceiling zone of a cool storing room having a guide casing suspended rotatingly around an approximately vertical axis, with at least one box-type annex (22) projecting horizontally from the circumference of the casing and being provided with blow profile sections (24), characterized in that the guide casing is linked as a running wheel (19) of a blower (20) with a drive and that it is fixed in the ceilling zone (3) of a maturation chamber for meat and sausages with the blow profile section (24) being provided at least at the side walls (23) of the annex (22).

Description

Die Erfindung betrifft eine Vorrichtung zur Konditionierung der Luft in kühlen Aufbewahruncsräumen für Lebensmittel, insbesondere in Reifungskammern für Fleisch- und Wurstwaren, mit wenigstens einem Gebläse und diesem zugeordneten Blasquerschnitt für Kühlluft.The invention relates to a device for conditioning the air in cool storage rooms for foodstuffs, in particular in ripening chambers for meat and sausage products, with at least one blower and a blower cross section for cooling air associated therewith.

Die sogenannten Reifungskammern für Fleisch- und Wurstwaren müssen nicht nur bezüglich der Temperatur sondern auch hinsichtlich der Luftfeuchte bestimmte Bedingungen erfüllen, da zu hohe Luftfeuchtigkeit den Reifungsprozeß verschlechtert, zu geringe Luftfeuchte ihn sogar unterbindet. Die in Reifungskammern verwendeten Gebläse werdenüblicherweise an der Kammerwandung festgelegt und blasen unter Bildung einer Blaszone parallel zur vertikalen Kammerwandung auf-oder abwärts.The so-called ripening chambers for meat and sausage products have to meet certain conditions not only with regard to the temperature but also with regard to the air humidity, since too high air humidity worsens the ripening process, and too low air humidity even prevents it. The blowers used in ripening chambers are usually attached to the chamber wall and blow up or down to form a blowing zone parallel to the vertical chamber wall.

Hierdurch wird zum einen der nutzbare Kammerquerschnitt vermindert, zum anderen ist der erzeugte Luftstrom nicht besonders wirkungsvoll.On the one hand, this reduces the usable chamber cross-section, on the other hand, the air flow generated is not particularly effective.

Angesichts dieser Gegebenheiten hat sich der Erfinder das Ziel gesetzt, eine Vorrichtung der eingangs erwähnten Art zu schaffen, welche -- unter Meidung der erkannten Nachteile -- bei einfacher Montage und Wartung ein optimales Konditionierverhalten anbietet.In view of these circumstances, the inventor has set himself the goal of creating a device of the type mentioned at the outset which, while avoiding the disadvantages identified, offers optimum conditioning behavior with simple assembly and maintenance.

Zur Lösung dieser Aufgabe führt eine im Aufbewahrungsraum in dessen Deckenbereich angeordnete Konditioniervorrichtung mit drehbar angetriebenem Laufrad und zumindest einem an diesem etwa horizontal angebrachten, mit dem Laufrad drehbaren Blasquerschnitt für die Kühlluft. Bevorzugt ragen vom Umfang des Laufrades mehrere -- im Idealfall drei -- Luftrohre mit jeweils zumindest einer Ausnehmung als Blasquerschnitt ab. Diese Blasquerschnitte drehen sich also unterhalb der Decke und führen an mehreren Stellen gleichzeitig die Kühlluft zu. Eine optimale Konditionierung wird dann erreicht, wenn erfindungsgemäß die Luftgeschwindigkeit an den Blasquerschnitten gesteuert und unterschiedlich eingestellt werden kann.To achieve this object, a conditioning device arranged in the storage area in the ceiling area thereof has a rotatably driven impeller and at least one blow cross section for the cooling air which is attached to it approximately horizontally and rotatable with the impeller. Preferably, from the circumference of the impeller, several - ideally three - air tubes each with at least one recess protrude as a blow cross section. These blow cross sections thus rotate below the ceiling and supply the cooling air at several points at the same time. Optimal conditioning is achieved when, according to the invention, the air speed at the blow cross sections can be controlled and adjusted differently.

Nach weiteren Merkmalen der Erfindung sind die Ausnehmungen in der Front- und/oder Seitenwandung der Luftrohre angebracht, wobei letztere;-etwa radial unter Verjüngung ihres Querschnittes vom Laufradumfang abragen. Dieser Querschnitt ist bevorzugt rechteckig und endet am freien Ende des Luftrohres -- wie beschrieben als Blasquerschnitt -- oder an einer Vorderwand des Luftrohres mit darin eingebrachter Ausnehmung. Außer diesen -- einen radialen Luftstrom begrenzenden -Blasquerschnitten können am Luftrohr auch seitliche Blasquerschnitte oder Ausnehmungen, vorgesehen werden, die dann etwa tangentiale Strömungsblenden darstellen.According to further features of the invention, the recesses are made in the front and / or side wall of the air tubes, the latter projecting approximately radially from the impeller circumference while tapering their cross section. This cross section is preferably rectangular and ends at the free end of the air tube - as described as a blow cross section - or on a front wall of the Air tube with recess made in it. In addition to these blow cross sections, which limit a radial air flow, lateral blow cross sections or recesses can also be provided on the air pipe, which then represent approximately tangential flow orifices.

Eine derartige Anordnung ist vor allem dann von Bedeutung, wenn -- wie ebenfalls von der Erfindung umfaßt -- nur ein radiales Luftrohr vom Umfang des Laufrades absteht, welches sich dann bevorzugt etwas mehr als ein mal in der Minute um die Vorrichtungsachse dreht. Diese Drehbewegung wird von einem Elektroantrieb und bevorzugt über einen Treibriemen gesteuert, welcher sich zwischen Laufradumfang einerseits und einer Riemenscheibe anderseits erstreckt; statt des Riementriebes kann auch ein Kettentrieb oder ein Zahntrieb Verwendung finden - mit diesen Antrieben ist es auf einfache und kostengünstige Weise möglich, die horizontale Drehbewegung des Laufrades zu erzeugen.Such an arrangement is particularly important if - as also encompassed by the invention - only one radial air tube protrudes from the circumference of the impeller, which then preferably rotates a little more than once a minute about the device axis. This rotary movement is controlled by an electric drive and preferably via a drive belt, which extends between the wheel circumference on the one hand and a pulley on the other hand; Instead of the belt drive, a chain drive or a toothed drive can also be used - with these drives it is possible to produce the horizontal rotary movement of the impeller in a simple and inexpensive manner.

Jenes Luftrohr ist an einem siebartig ausgebildeten Krümmungsteil des Laufradumfanges vorgesehen, wobei der Querschnitt jeder Sieböffnung dieses Krümmungsteiles erfindungsgemäß geringer ist als der Blasquerschnitt selbst.That air tube is provided on a sieve-like curved part of the impeller circumference, the cross section of each sieve opening of this curved part being smaller according to the invention than the blowing cross section itself.

Die Lagerung des sich drehenden Laufradumfanges erfolgt erfindungsgemäß durch Laufrollen, beispielsweise Teflonscheiben,an etwa radial gerichteten Wellenstümpfen; letztere sind bevorzugt in einer Tragwand des Laufrades festgelegt - diese Tragwand ist etweder mit Luftdurchtrittsöffnungen versehen oder als Fachwerk ausgebildet und gestattet so eine freie Luftströmung.According to the invention, the rotating circumference of the impeller is supported by rollers, for example Teflon discs, on approximately radially directed shaft ends; the latter are preferably fixed in a supporting wall of the impeller - this supporting wall is either provided with air passage openings or is designed as a framework and thus allows a free air flow.

Die Laufrollen sind bevorzugt mit Umfangsnuten versehen und sitzen dank dieser geführt auf dem Kopf der Führungsschiene. Eine sehr genaue Führung des Laufrades wird dadurch erreicht, daß man übereinander zwei Reihen von Laufrädern vorsieht, deren untere auf einer Führungsschiene ruht und deren obere in einer weiteren, von oben her eingreifenden Führungsschiene läuft; hierdurch ist ein Verkanten des Laufrades nicht mehr möglich. Sein Auswechseln wird dadurch erleichtert, daß eine Laufrollenreihe lösbar an der Tragwand festliegt.The rollers are preferably provided with circumferential grooves and, thanks to these, sit on the head of the guide rail. A very precise guidance of the impeller is achieved by providing two rows of impellers one above the other, the lower of which rests on a guide rail and the upper of which runs in another guide rail which engages from above; tilting of the impeller is no longer possible. Its replacement is made easier by the fact that a row of rollers is releasably attached to the supporting wall.

Um unerwünschte Seitenströme zu vermeiden, ist zwischen dem sich drehenden Laufrad einerseits und dem stehenden Teil des Lüfters, beispielsweise seinem Gehäuse, anderseits zumindest eine Dichtung vorgesehen.In order to avoid undesirable side currents, at least one seal is provided between the rotating impeller on the one hand and the stationary part of the fan, for example its housing, on the other.

Unterhalb des Lüfters sind Kälte- und Wärmeregister angeordnet sowie an diesen bevorzugt Tropfenabscheider, welche eine Regulierung der Feuchtetracht im aufsteigenden-Luftstrom erlauben; dieser durchfährt zuerst das Kälteregister, wird anschließend im Wärmeregister weiter konditioniert und dann -- nach dem Austreiben von Tropfen an den Tropfenabscheidern im Laufrad in horizontale Richtung umgelenkt zu werden. In den Auffangrinnen der Tropfenabscheider gefangenes Kondensat wird durch Ablaufleitungen entfernt.Cold and heat registers are arranged below the fan, and preferably droplet separators are arranged on them, which allow the moisture content in the rising air flow to be regulated; this first passes through the cold register, is then further conditioned in the heat register and then - after dropping droplets on the droplet separators in the impeller - is redirected in the horizontal direction. Condensate caught in the gutters of the droplet separators is removed by drain lines.

Dank der erfindungsgemäßen Vorrichtung wird die reifende Ware nicht mehr -- wie bislang -- direkt angeblasen; das Ausblasen geschieht in einer deckennahen Konditionierzone unter Vergleichmäßigung der Luftzirkulation bei dreiseitiger Luftströmung.Thanks to the device according to the invention, the ripening goods are no longer blown on directly as before; the blowing out takes place in a conditioning zone near the ceiling, with equalization of the air circulation with three-sided air flow.

In der Reifungskammer entfallen dank der Erfindung sogenannte stille Zonen.Thanks to the invention, so-called quiet zones are eliminated in the ripening chamber.

Eine erhebliche Erleichterung ergibt sich bei der Montage dank der Kompaktbauweise der Vorrichtung, da ortsgebundene Luftkanäle nicht mehr benötigt werden. Zudem kann der vertikale Abstand der Vorrichtung zum Kammerboden nach Wahl verändert werden.The compact design of the device makes installation much easier, since localized air ducts are no longer required. In addition, the vertical distance of the device from the chamber floor can be changed as desired.

In einen von einem Boden 1, Seitenwänden 2 und einer Decke 3 begrenzten Kühlraum 4 für zu reifende Fleischwaren 5 ist eine Vorrichtung 10 an der Decke 3 festgelegt.A device 10 is fixed to the ceiling 3 in a cooling space 4 for meat products 5 to be matured, which is delimited by a floor 1, side walls 2 and a ceiling 3.

Diese Vorrichtung 10 weist gemäß Fig. 1 in einem Rahmen 11 ein Kälteregister 12 sowie ein Wärmeregister 13 aus einer Kupfer- Aluminiumlegierung auf. Außerhalb des Rahmens 11 ruht auf einer Konsole 14 ein Elektromotor 15 als Antrieb für eine Riemenscheibe 16.1, in a frame 11, this device 10 has a cold register 12 and a heat register 13 made of a copper-aluminum alloy. An electric motor 15, which drives a pulley 16, rests on a bracket 14 outside the frame 11.

Ein die Riemenscheibe 16 teilweise umfangender Keilriemen 17 ist anderseits um den Umfang 18 des Laufrades 19 eines Lüfters 20 gelegt; dieses Laufrad 19 lagert -- um eine Achse A drehbar -- zwischen dem Wärmeregister 13 und einem an der Decke 3 festliegenden Tragrahmen 21.A V-belt 17 partially encompassing the pulley 16 is on the other hand placed around the circumference 18 of the impeller 19 of a fan 20; this impeller 19 is mounted - rotatable about an axis A - between the heat register 13 and a support frame 21 fixed to the ceiling 3.

Vom Umfang 18 des Laufrades 19 ragt in Fig. 1 radial ein Luftrohr 22 rechteckigen Querschnittes mit in seinen Seitenwänden 23 vorgesehenen Luftöffnungen 24 ab.In FIG. 1, an air tube 22 of rectangular cross section projects radially from the circumference 18 of the impeller 19 with air openings 24 provided in its side walls 23.

Wie Fig. 2 verdeutlicht, verjüngt sich der Querschnitt des Luftrohres 22 zu dessen Vorderwand 25 hin von einer inneren Weite i von beispielsweise 400 mm auf eine äußere Weite b von dann 330 mm bei einer Kraglänge a von 270 mm. Dieses Luftrohr 22 ist vom Umfang 18 des Laufrades 19 an einem Löcher 26 aufweisenden siebartigen Krümmungsbereich 27 festgelegt, dem gegenüber die Vorderwand 25 des Luftrohres 22 ebenfalls mit einer Ausnehmung 28 versehen ist.As illustrated in FIG. 2, the cross section of the air tube 22 tapers towards its front wall 25 from an inner width i of, for example, 400 mm to an outer width b of then 330 mm with a cantilever length a of 270 mm. This air tube 22 is fixed by the circumference 18 of the impeller 19 to a sieve-like curvature region 27 which has holes 26 and to which the front wall 25 of the air tube 22 is likewise provided with a recess 28.

Der Umfang 18 des Laufrades 19 weist einen Durchmesser d von beispielsweise 660 mm auf, eine innerhalb dessen vorgesehene Tragwand 29 einen Durchmesser e von 600 mm.The circumference 18 of the impeller 19 has a diameter d of, for example, 660 mm, a support wall 29 provided within it has a diameter e of 600 mm.

Der Umfang 18 des Laufrades 19 ist durch Winkelstücke 30 mit der Tragwand 29 verbunden und bildet mit dieser das Laufrad 19, dessen horizontale Radkränze 31 unter Zwischenschaltung von Dichtungen 32 dem Rahmen 11 an- bzw. aufliegen.The circumference 18 of the impeller 19 is connected to the support wall 29 by angle pieces 30 and forms the impeller 19 with the latter, the horizontal wheel rims 31 of which rest on or rest on the frame 11 with the interposition of seals 32.

Von der Tragwand 29 ragen zum Vorrichtungsinneren 33 hin Wellenstümpfe 34 für splintgesicherte Teflonrollen 35 ab, in deren Umfangsnuten 36 Führungsschienen 37 des Rahmens 11 eingreifen.From the support wall 29 protrude toward the interior 33 of the device shaft ends 34 for pin-secured Teflon rollers 35, 36 guide rails 37 of the frame 11 engage in the circumferential grooves.

Diese sind kreisförmig um die Achse A gelegt und erlauben ein Drehen des Laufrades 19 in einer aus der Zeichnung ersichtlichen Weise. Sowohl die Anordnung dieser Führungsschienen 37 als auch die Ausbildung jener Tragwand 29 mit Ausnehmungen 38 erlaubt eine Luftströmung quer durch den Lüfter 20.These are placed in a circle around the axis A and allow the impeller 19 to be rotated in a manner shown in the drawing. Both the arrangement of these guide rails 37 and the formation of that support wall 29 with recesses 38 allow air to flow across the fan 20.

Fig. 5 läßt zwei übereinander liegende Reihen von Lauf-oder Teflonrollen 35 erkennen, von denen die untere durch Schrauben 39 lösbar ist.5 shows two rows of running or Teflon rollers 35 lying one above the other, of which the lower one can be released by screws 39.

Die untere Führungsschiene 37 ruht auf einem Wannenboden 40, dem Tropfenabscheiderprofile 41 hakenähnlichen Querschnittes zugeordnet sind. Letztere entziehen einer in Pfeilrichtung x durchziehenden Luft darin enthaltene Flüssigkeitspartikel und erlauben so eine Regulierung der Luftfeuchtigkeit.The lower guide rail 37 rests on a trough base 40 to which the droplet separator profiles 41 are assigned a hook-like cross section. The latter withdraw liquid particles contained therein in the direction of the arrow x and thus allow the air humidity to be regulated.

Bei dem in Fig. 7 wiedergegebenen Ausführungsbeispiel sind am Umfang 18 des Laufrades 19 mehrere Luftrohre 22 in radialer Richtung angeordnet, die eine besonders günstige horizontale Verteilung eines Luftstromes ermöglichen; dies Art der Luftführung verhindert zu hohe Turbulenzen im Kühlraum 4 und damit eine besonders günstige Reifung der dort befindlichen Fleischwaren 5.In the exemplary embodiment shown in FIG. 7, a plurality of air tubes 22 are arranged on the circumference 18 of the impeller 19 in the radial direction, which allow a particularly favorable horizontal distribution of an air flow; This type of airflow prevents excessive turbulence in the cooling space 4 and thus a particularly favorable maturation of the meat products 5 located there.

In der Zeichnung nicht erkennbar ist die vorhandene Höhenverstellbarkeit der Vorrichtung 10 insgesamt oder des Lüfters 20 in Verbindung mit der Konsole 14 - und somit des Elektromotors 15. Der lichte Bodenabstand q für den Lüfter 20 beträgt bevorzugt 250 cm, die Laufradhöhe n etwa 15 cm.The existing height adjustability of the device 10 as a whole or of the fan 20 in connection with the console 14 - and thus of the electric motor 15, cannot be seen in the drawing. The clear ground clearance q for the fan 20 is preferably 250 cm, the impeller height n is approximately 15 cm.
