PCT No. PCT/CH92/00170 Sec. 371 Date May 28, 1993 Sec. 102(e) Date May 28, 1993 PCT Filed Aug. 26, 1992 PCT Pub. No. WO93/06988 PCT Pub. Date Apr. 15, 1993.The rod-shaped flexible core (6) of a drainage element (2) mounted in a pressing space (1) of a fruit press has several longitudinal grooves (8, 13) on its periphery, through which the extracted juice is conveyed to juice collecting spaces (5). The free ends of each drainage element (2) are detachably fastened by drainage locks (3) to juice collecting plates (4) bordering the pressing space (1). In the area of rigid drainage lock (3), through which the juice is guided, the longitudinal grooves (8) are widened, so that in this area, in which the flexibility of core (6) to assist the flow process is absent, the risk of clogging by solid sediment particles in the juice is prevented.

Description

Drainageelement für Pressen. Drainage element for presses.
Die Erfindung betrifft ein Drainageelement für Pressen zum Ausscheiden von Flüssigkeiten aus festen Stoffen, insbeson¬ dere Früchtepressen, bestehend aus einem stabförmigen, flexiblen Kern mit Fließwegen zum Ableiten der ausgepressten Flüssigkeit aus dem Pressraum und einer den Kern umgebenden, flüssigkeitsdurchlässigen Filterhülle, wobei mindestens ein Ende des Drainageelements über ein Dra'inageschloß an einer Saftsammeiplatte oder am Pressmantel befestigt ist.The invention relates to a drainage element for presses for separating liquids from solid substances, in particular fruit presses, consisting of a rod-shaped, flexible core with flow paths for discharging the pressed-out liquid from the press chamber and a liquid-permeable filter sleeve surrounding the core, at least one end of the drainage element via a Dra 'inageschloß at a Saftsammeiplatte or fixed to the press cover.
Eine größere Anzahl derartiger Drainageelemente ist bei¬ spielsweise im Pressraum einer Früchtepresse zwischen der beweglichen und der feststehenden Druckplatte angeordnet. Beim Pressvorgang bzw. beim Zufahren der beweglichen Druck¬ platte verformen sich die flexiblen Drainageelemente. Dabei durchdringt der ausgepresste Saft die Filterhülle des Drai- nageelements und wird entlang den Fließwegen des stabförmi- gen Kerns aus dem Pressraum herausgeführt und in einen Saftsammei aum geleitet. Hierzu sind beide Enden oder bei einseitiger Befestigung nur ein Ende des Drainageelements an den Druck- oder Saftsammelplatten, die einerseits den Press¬ raum und andererseits den Saftsammeiräum begrenzen, lösbar befestigt. Die Fließwege für den Saft werden durch Längsnu¬ ten gebildet, die am Außenumfang des Kerns angeordnet sind und über das Drainageschloß in den Saftsammeiraum münden.A larger number of such drainage elements is arranged, for example, in the press chamber of a fruit press between the movable and the fixed pressure plate. The flexible drainage elements deform during the pressing process or when the movable pressure plate is closed. The squeezed juice penetrates the filter cover of the drain nageelements and is led out of the pressing space along the flow paths of the rod-shaped core and directed into a juice collection. For this purpose, both ends or, in the case of one-sided fastening, only one end of the drainage element are detachably fastened to the pressure or juice collecting plates, which on the one hand delimit the press chamber and on the other hand delimit the juice collecting chamber. The flow paths for the juice are formed by longitudinal grooves, which are arranged on the outer circumference of the core and open into the juice collection space via the drainage lock.
Die ausgepressten Säfte sind je nach Pressgut stark mit feinen Feststoff- bzw. Trubteiien belastet. Beim Fliessvor¬ gang durch die Längsnuten des Drainageelements können sich kleine Trubklumpen bilden, die durch die Biegebewegungen der flexiblen Drainagekerne in ihrer Fliessbewegung unterstützt werden. Im inneren Bereich der starren Drainageschlösser fehlt jedoch diese Bewegungs-Unterstützung und es bilden sich teilweise feste Trubpfropfen, welche die Längsnuten des Drainagekerns verstopfen. Der Saftablauf kann dadurch stark behindert werden, mit der Folge erhöhter Ausbeute- und Leistungsverluste. Die Beseitigung der Verstopfungen ist oftmals sehr mühsam und zeitraubend, da die Drainageelemente ausgebaut werden müssen und der Arbeitsablauf der Presse unterbrochen wird. Ausserdem ist eine vermehrte chemische Reinigung erforderlich.Depending on the material to be pressed, the pressed juices are heavily contaminated with fine solids or trub particles. During the flow process through the longitudinal grooves of the drainage element, small lumps of trub can form, which are supported in their flow movement by the bending movements of the flexible drainage cores. In the inner area of the rigid drainage locks, however, this movement support is missing and solid trub plugs are formed, which clog the longitudinal grooves of the drainage core. Juice drainage can be severely hampered, resulting in increased yield and performance losses. The removal of the blockages is often very tedious and time-consuming because the drainage elements have to be removed and the workflow of the press is interrupted. In addition, increased chemical cleaning is required.
Der Erfindung liegt die Aufgabe zugrunde die genannten Nachteile zu vermeiden und Verstopfungen im Bereich der Drainageschlösser zu verhindern, um dadurch die Funktion und die Leistung der Presse zu verbessern.The invention has for its object to avoid the disadvantages mentioned and blockages in the area Prevent drainage locks to improve the function and performance of the press.
Diese Aufgabe wird gemäss der Erfindung dadurch gelöst, dass die Fliesswege des Drainageelements im Bereich des Draina¬ geschlosses vergrössert sind.According to the invention, this object is achieved in that the flow paths of the drainage element are enlarged in the region of the drain lock.
Vorteilhafterweise werden die Fliesswege des Drainageele¬ ments durch am Aussenumfang des Kerns angeordneten Längsnu¬ ten gebildet, die im Bereich des Drainageschlosses vergrös¬ sert sind.The flow paths of the drainage element are advantageously formed by longitudinal grooves which are arranged on the outer circumference of the core and which are enlarged in the region of the drainage lock.
Eine besonders einfache, auch bei bereits ausgelieferten Saftpressen anwendbare Massnahme zur Vergrösserung der Längsnuten besteht darin, dass jeder zweite, zwischen den Längsnuten gebildete Steg des Drainagekerns im Bereich des Drainageschlosses entfernt wird.A particularly simple measure for enlarging the longitudinal grooves, which can also be applied to juice presses already delivered, consists in removing every second web of the drainage core formed between the longitudinal grooves in the region of the drainage lock.
In einer anderen Ausführungsform der Erfindung sind die Längsnuten im Bereich des Drainageschlosses konisch erwei¬ tert.In another embodiment of the invention, the longitudinal grooves in the region of the drainage lock are flared.
Eine weitere Möglichkeit zur Vergrösserung der Fliesswege besteht darin, dass die Tiefe der Längsnuten im Bereich des Drainageschlosses vergrössert ist.Another way of increasing the flow paths is to increase the depth of the longitudinal grooves in the area of the drainage lock.
Die mit der Erfindung erzielten Vorteile bestehen insbeson¬ dere darin, dass infolge der Erweiterung der Fliesskanäle im Bereich des starren Drainageschlosses die einfliessenden Trubteile in ihrer Fliessbewegung nicht mehr gehemmt werden und sogleich nach aussen in den Saftsa melrau gespült werden. Die Verweilzeit in den erweiterten Fliesskanälen ist für ein schnelles Anwachsen der Trubteilchen zu kurz. Eine Verstopfung der Fliesskanäle wird somit erfolgreich verhin¬ dert und die Leistung der Presse erhöht. Der Zeitabstand zwischen den periodisch durchzuführenden Reinigungsarbeiten der Presse kann dadurch ebenfalls vergrössert werdenThe advantages achieved with the invention are in particular that, due to the expansion of the flow channels in the area of the rigid drainage lock, the inflowing ones Turbid parts are no longer inhibited in their flow movement and are immediately washed out into the juice chamber. The dwell time in the extended flow channels is too short for a fast growth of the sediment particles. Clogging of the flow channels is thus successfully prevented and the performance of the press is increased. The interval between the periodic cleaning work of the press can also be increased

Fig. 3 einen Schnitt durch das Drainageelement gemäss der Linie III - III in Fig. 23 shows a section through the drainage element along the line III-III in FIG. 2
In einem Pressraum 1 einer nicht näher dargestellten Früch¬ tepresse sind mehrere Drainageelemente 2 angeordnet. Die freien Enden des Drainageelements 2 sind jeweils über ein Drainageschloss 3 an Saftsammelplatten 4, die einerseits den Pressraum 1 und andererseits Saftsammeiräume 5 begrenzen, lösbar befestigt. Der Einfachheit halber ist nur eine der beiden Saftsammelplatte 4, von denen die andere als bewegliche Druckplatte ausgeführt ist, dargestellt. Jedes Drainageelement 2 besteht aus einem stabförmigen, flexiblen Kern 6, der von einer Strumpfartigen Filterhülle 7 umgeben ist. Der Kern 6 weist mehrere, am Umfang verteilte Längsnu¬ ten 8 auf, die als Fliesswege für den ausgepressten Saft dienen. Die Befestigung der Filterhülle 7 auf dem Kern 6 erfolgt durch ein Steckteil 9, das mit einer Hülse 10 die Saftsammelplatte 4 durchsetzt. Das Steckteil 9, die Hülse 10 und die Saftsammelplatte 4 bilden zusammen das Drainage¬ schloss 3, das eine lösbare Befestigung des Drainageelements 2 an der Saftsammelplatte 4 ermöglicht. Die Hülse 10, die in den Saftsammeiräum 5 hineinragt, weist Bohrungen 11 für den Austritt des Saftes auf, der über die Längsnuten 3 des Drainageelements 3 durch das. Drainageschloss 3 hindurchgefüh wird.A plurality of drainage elements 2 are arranged in a press space 1 of a fruit press, not shown in detail. The free ends of the drainage element 2 are each releasably attached via a drainage lock 3 to juice collecting plates 4, which on the one hand delimit the pressing chamber 1 and on the other hand juice collecting chambers 5. For the sake of simplicity, only one of the two juice collecting plates 4, the other of which is movable pressure plate is shown. Each drainage element 2 consists of a rod-shaped, flexible core 6, which is surrounded by a stocking-like filter cover 7. The core 6 has a plurality of longitudinal grooves 8 distributed around the circumference, which serve as flow paths for the pressed juice. The filter sleeve 7 is fastened to the core 6 by a plug-in part 9 which penetrates the juice collecting plate 4 with a sleeve 10. The plug-in part 9, the sleeve 10 and the juice collecting plate 4 together form the drainage lock 3, which enables the drainage element 2 to be detachably fastened to the juice collecting plate 4. The sleeve 10, which projects into the juice collecting space 5, has bores 11 for the exit of the juice, which is guided through the drainage lock 3 via the longitudinal grooves 3 of the drainage element 3.
Zwischen den Längsnuten 8 des Kerns 6 sind Stege 12 gebildet, durch die die Längsnuten 8 voneinander getrennt werden. An den Enden des Kerns 6 ist jeweils jeder zweite Steg 12 entfernt. Dadurch entstehen neue Längsnuten 13, die gegenüber den Längsnuten 8 um etwa das Zwei- bis Dreifache verbreitert sind. Die Länge der Längsnuten 13 entspricht etwa der Länge des Bereiches, in dem das Drainageelement 2 infolge seiner Halterung im starren Drainageschloss 3 unbeweglich ist.Crosspieces 12 are formed between the longitudinal grooves 8 of the core 6, by means of which the longitudinal grooves 8 are separated from one another. Every second web 12 is removed at the ends of the core 6. This creates new longitudinal grooves 13 which are widened by approximately two to three times compared to the longitudinal grooves 8. The length of the longitudinal grooves 13 corresponds approximately to the length of the area in which the drainage element 2 is immobile due to its mounting in the rigid drainage lock 3.
Die Wirkungsweise der Erfindung ist wie folgt.The operation of the invention is as follows.
Beim Pressvorgang wird die als bewegliche Druckplatte ausgebildete Saftsammelplatte in axialer Richtung gegen die feststehende Saftsammelplatte 4 zugefahren, wobei die flexiblen Drainageelemente 2 Biegebewegungen ausführen und seitlich ausknicken. Dabei gelangt der ausgepresste Saft durch die flüssigkeitsdurchlässige Filterhülle 7 hindurch zum Kern 6 und wird durch die Längsnuten 8 und 13 in den Saftsammeiräum 5 geleitet.During the pressing process it is used as a movable pressure plate trained juice collecting plate in the axial direction against the fixed juice collecting plate 4, wherein the flexible drainage elements perform 2 bending movements and buckle laterally. The squeezed juice reaches the core 6 through the liquid-permeable filter casing 7 and is guided through the longitudinal grooves 8 and 13 into the juice collecting space 5.
Die sich beim Fliessvorgang bildenden, festen Trubteile 14 werden, unterstützt durch die Biegebewegungen des Drainage¬ elements 2, über die Längsnuten 8 abgeführt und gelangen im Bereich des starren Drainageschlosses 3, wo die Bewegungs- Unterstützung durch die Flexibilität des Drainageelements 2 fehlt, in die erweiterten Längsnuten 13. Aufgrund der vergrösserten Fliessquerschnitte der Längsnuten 13 werden die festen Trubteile 14 ohne Verstopfung zusammen mit dem Saft in den Saftsammeir um δ geleitet.The solid trub parts 14 formed during the flow process, supported by the bending movements of the drainage element 2, are discharged via the longitudinal grooves 8 and reach the area of the rigid drainage lock 3, where there is no movement support due to the flexibility of the drainage element 2 widened longitudinal grooves 13. Due to the enlarged flow cross-sections of the longitudinal grooves 13, the solid sediment parts 14 are led together with the juice into the juice collector by δ without clogging.
Anstelle des Entfernens der Stege 12 können als weitere Massnahme zur Vorgrδsserung der Fliesswege die Längsnuten 10 im Bereich des Drainageschlosses konisch erweitert oder die Nutentiefe vergrössert werden. Instead of removing the webs 12, the longitudinal grooves 10 in the region of the drainage lock can be flared or the groove depth increased as a further measure for pre-enlarging the flow paths.
