Abstract

In a juice belt press for removing juice from fruit mash, an endless screening press belt (22) runs in serpentine fashion between pressing rolls (3) and reversing rolls (4) arranged between the pressing rolls (3). The reversing rolls (4) are mounted to be pivotable in the frame (1) of the device about pivoting axes (32) via supports (30) and bearing supports (33). The bearing supports (33) of the supports (30) for the reversing rolls (4) are adjustable so that the distance of the resultant from the forces exerted by the screening press belt (22) on the reversing roll (4) from the pivoting axis (32) of the supports (30) can be varied. In this way, the magnitude of the moment, by means of which the reversing roll (4) is pressed onto one or the other of the adjacent press rolls (3), can be adjusted to the most advantageous value at the time, in order to increase the contact pressure between the screening press belt (22) and the press roll (3) at the end of a looping zone between the screening press belt (22) and the press roll (3). <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Auspressen von Flüssigkeit aus die Flüssigkeit enthaltenden Stoffen, insbesondere zum Entsaften von Obstmaische, mit einem endlosen Siebpreßband, das in der Vorrichtung serpentinenartig geführt ist, wobei der Stoff auf der Preßwalzen zugekehrten Seite des Siebpreßbandes aufgebracht ist, und wobei zwischen den in einem Rahmen der Vorrichtung gelagerten Preßwalzen im Rahmen der Vorrichtung gelagerte Umlenkwalzen für das Siebpreßband vorgesehen sind.The invention relates to a device for squeezing liquid from the liquid-containing substances, in particular for juicing fruit mash, with an endless screen press belt, which is guided in the device like a serpentine, the substance being applied to the side of the screen press belt facing the press rollers, and between the deflecting rollers mounted in a frame of the device are provided for the screen press belt in the frame of the device.

Zum Auspressen von Flüssigkeiten aus Stoffen sind Vorrichtungen bekannt, bei welchen der Stoff, z.B. Obstmaische, zwischen Siebpreßbändern über Entwässerungstrommeln geführt wird, wobei die Siebpreßbänder die Entwässerungstrommeln über einen Teil ihres Umfanges umschlingen. Derartige Vorrichtungen sind beispielsweise aus der AT-PS 363 872 oder der EP-B-13 549 bekannt.Devices for squeezing liquids out of substances are known in which the substance, e.g. Fruit mash is passed between sieve press belts over drainage drums, the sieve press belts wrapping around the drainage drums over part of their circumference. Such devices are known for example from AT-PS 363 872 or EP-B-13 549.

Aus dem Aufsatz "Im Westen nichts Neues?" in "Flüssiges Obst, Fachzeitschrift der Fruchtsaft-, Gemüsesaft- und Fruchtweinindustrie", Heft 8/91, Seite 448 ist eine Vorrichtung der eingangs genannten Gattung bekannt, die als Obstbandpresse ausgelegt ist. Bei dieser bekannten Obstbandpresse wird das Siebpreßband serpentinenartig zwischen Preßwalzen und Umlenkwalzen geführt. Nicht gelöst bei dieser bekannten Obstbandpresse ist das Problem des richtigen und ggf. einstellbaren Anpreßdruckes zwischen dem Siebpreßband und den Preßwalzen, da sowohl die Preßwalzen als auch die Umlenkwalzen im Rahmen der bekannten Obstbandpresse starr gelagert sind.From the essay "Nothing new in the West?" in "Liquid Fruit, Trade Journal of the Fruit Juice, Vegetable Juice and Fruit Wine Industry", Issue 8/91, page 448, a device of the type mentioned at the outset is known, which is designed as a fruit belt press. In this known fruit belt press, the screen press belt is guided in a serpentine manner between press rolls and deflection rolls. The problem of the correct and possibly adjustable contact pressure between the screen press belt and the press rolls is not solved in this known fruit band press, since both the press rolls and the deflecting rolls are rigidly mounted within the known fruit band press.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Gattung, insbesondere eine Siebbandpresse zum Entsaften von Obstmaische zu schaffen, mit welcher auch bei Verwendung eines einzigen, endlos umlaufenden Siebpreßbandes ein leistungsfähiges Entsaften von Obstmaische bzw. allgemein ein leistungsfähiges Auspressen von Flüssigkeit aus Flüssigkeit enthaltenden Stoffen möglich ist.The invention has for its object to provide a device of the type mentioned, in particular a belt press for juicing fruit mash, with which even when using a single, endlessly rotating screen press belt an efficient juicing of fruit mash or, in general, an efficient squeezing out of liquid from substances containing liquid is possible.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß wenigstens eine der zwischen den Preßwalzen vorgesehenen Umlenkwalzen an im Rahmen der Vorrichtung verschwenkbar gelagerten Trägern gelagert ist.According to the invention, this object is achieved in that at least one of the deflection rolls provided between the press rolls is mounted on supports which are pivotably mounted in the device.

Aufgrund der erfindungsgemäß vorgeschlagenen Lagerung einer, mehrerer oder aller Umlenkwalzen für das Siebpreßband kann die unter der Wirkung der Spannung des Siebpreßbandes entstehende Andrückkraft der Umlenkwalze(n) auf eine der benachbarten Preßwalzen, insbesondere im Bereich am Ende der Umschlingung der Preßwalze durch das Siebpreßband auf den jeweils gewünschten zusätzlichen Druck auf den zu pressenden Stoff (Obstmaische) eingestellt werden. Je nach der Ausrichtung der Schwenkachse der Träger, welche die Umlenkwalze tragen, geht nämlich die Resultierende aus den vom Siebpreßband auf die Umlenkwalze ausgeübten Kräften entweder durch die Schwenkachse der Träger (neutrale Stellung) oder die Resultierende hat von der Schwenkachse einen Abstand, so daß sich ein die Umlenkwalze gegen die benachbarte Preßwalze drückendes Moment ergibt.Due to the storage of one, several or all deflection rollers for the screen press belt proposed according to the invention, the pressing force of the deflection roller (s) under the action of the tension of the screen press belt can be exerted on one of the adjacent press rolls, in particular in the area at the end of the wrapping of the press roll by the screen press belt on the the desired additional pressure on the material to be pressed (fruit mash). Depending on the orientation of the pivot axis of the carriers that carry the deflection roller, the resultant goes from the forces exerted by the screen press belt on the deflection roller either through the pivot axis of the carriers (neutral position) or the resultant has a distance from the pivot axis, so that a moment pressing the deflection roller against the adjacent press roller.

In einer praktischen Ausführungsform der erfindungsgemäßen Vorrichtung kann vorgesehen sein, daß die Achsen der Preßwalzen und der Umlenkwalzen horizontal ausgerichtet und im wesentlichen in einer Ebene angeordnet sind.In a practical embodiment of the device according to the invention it can be provided that the axes of the press rolls and the deflecting rolls are aligned horizontally and arranged essentially in one plane.

In der Praxis bewährt sich eine Vorrichtung gemäß der Erfindung, bei welcher vorgesehen ist, daß Preßwalzen in Richtung der Bewegung des Siebpreßbandes einen abnehmenden Durchmesser besitzen.A device according to the invention has proven itself in practice, in which it is provided that the press rolls have a decreasing diameter in the direction of the movement of the screen press belt.

Eine bevorzugte Ausführungsform der erfindungsgemäßen Vorrichtung besteht darin, daß die Träger der Umlenkwalze an im Rahmen verstellbaren Lagern gelagert ist. Bei dieser Ausführungsform kann der Anpreßdruck, d.h. der Druck, mit welchem die wenigstens eine Umlenkwalze unter der Wirkung der Spannung des Siebpreßbandes über das Siebpreßband an der ihr zugeordneten Preßwalze anliegt, auf den jeweils gewünschten Wert dadurch eingestellt werden, daß die Stellung der Lager geändert und dadurch die Lage der oben erwähnten Resultierenden zur Schwenkachse der Träger der Umlenkwalze entsprechend gewählt wird. Dadurch ist es möglich, den zusätzlichen Druck, der vom Siebpreßband unter der Wirkung der Umlenkwalze auf den Stoff ausgeübt wird, an die Eigenschaften bzw. den Entwässerungs-(Entsaftungs)grad des Stoffes (Obstmaische) anzupassen.A preferred embodiment of the device according to the invention is that the carrier of the deflecting roller is mounted on bearings which are adjustable in the frame. In this embodiment, the contact pressure, ie the pressure with which the at least one deflecting roller under the action of the tension of the screen press belt on the screen press belt on the associated with it Press roller is present, can be adjusted to the desired value by changing the position of the bearings and thereby the position of the above-mentioned resultant to the pivot axis of the carrier of the deflection roller is selected accordingly. This makes it possible to adapt the additional pressure exerted on the fabric by the screen press belt under the action of the deflecting roller to the properties or the degree of dewatering (juicing) of the fabric (fruit mash).

In einer praktischen Ausführungsform der erfindungsgemäßen Vorrichtung kann vorgesehen sein, daß die Umlenkwalze an ihren Trägern im Abstand von einer durch die Schwenkachse der Träger gehenden Ebene gelagert ist. Die Träger haben bei dieser Ausführungsform beispielsweise einen von ihnen senkrecht abstehenden Schenkel, an dem die Umlenkwalze gelagert ist.In a practical embodiment of the device according to the invention it can be provided that the deflection roller is mounted on its supports at a distance from a plane passing through the pivot axis of the supports. In this embodiment, the carriers have, for example, one leg which projects vertically from them and on which the deflecting roller is mounted.

Bei dieser Ausführungsform wird die Umlenkwalze unter der Wirkung der Spannung des Siebpreßbandes zusätzlich auf die Preßwalze zu belastet und damit der Anpreßdruck des Siebpreßbandes an die Preßwalze erhöht, die auf der Seite angeordnet ist, welcher die Achse des Trägers von der durch die Schwenkachse des Trägers gehenden Ebene benachbart ist.In this embodiment, the deflecting roller is additionally loaded under the action of the tension of the screen press belt on the press roll and thus increases the contact pressure of the screen press belt on the press roll, which is arranged on the side which the axis of the carrier from the going through the pivot axis of the carrier Level is adjacent.

Das Verstellen der Träger für die Umlenkwalze und damit das Wählen des Anpreßdruckes derselben an die ihr zugeordnete Preßwalze gestaltet sich besonders einfach, wenn gemäß einem Vorschlag der Erfindung vorgesehen ist, daß die Träger der Umlenkwalze an Lagerträgern gelagert sind, die an im wesentlichen senkrecht zu den Achsen der Preßwalzen verlaufenden Teilen des Rahmens der Vorrichtung festklemmbar sind.The adjustment of the carrier for the deflecting roller and thus the selection of the contact pressure of the same to the press roller assigned to it is particularly simple if, according to a proposal of the invention, it is provided that the carriers of the deflecting roller are mounted on bearing supports which are essentially perpendicular to the Axes of the press rolls extending parts of the frame of the device can be clamped.

Weitere Einzelheiten, Merkmale und Vorteile der Erfindung ergeben sich aus der nachstehenden Beschreibung des in den Zeichnungen dargestellten bevorzugten Ausführungsbeispieles der Erfindung. Es zeigt:

  • Fig. 1 eine Siebbandpresse in Seitenansicht und
  • Fig. 2 eine Einzelheit der Siebbandpresse im Bereich einer verschwenkbar gelagerten Umlenkwalze.
Further details, features and advantages of the invention result from the following description of the preferred exemplary embodiment of the invention illustrated in the drawings. It shows:
  • Fig. 1 is a belt press in side view
  • Fig. 2 shows a detail of the belt press in the region of a pivotally mounted deflection roller.

Die erfindungsgemäße Siebbandpresse besitzt einen Rahmen 1, in dem oben ein Maischebehälter 2 mit Maischeaufgabe montiert ist. Im Rahmen 1 sind um horizontal ausgerichtete und im gezeigten Ausführungsbeispiel im wesentlichen in einer horizontalen Ebene liegenden Drehachsen gelagerte Preßwalzen 3, 3', 3'' und 3''' gelagert. Die Preßwalzen 3, 3', 3'' und 3''' sind in Lagerträgern 20 gelagert, die an einem sich im wesentlichen horizontal erstreckenden Hauptträger 21 des Rahmens 1 befestigt sind. Zwischen den Preßwalzen 3 sind Umlenkwalzen 4, 4' und 4'' vorgesehen. Im Rahmen 1 ist in Fig. 1 ganz links eine Antriebswalze 5 für ein Siebpreßband 22 vorgesehen. Diese Antriebswalze 5 wird durch einen nicht gezeigten Motor angetrieben.The belt filter press according to the invention has a frame 1, in which a mash container 2 with mash feed is mounted at the top. In the frame 1, press rolls 3, 3 ', 3' 'and 3' '' are mounted around horizontally aligned axes of rotation, which in the exemplary embodiment shown are essentially in a horizontal plane. The press rolls 3, 3 ', 3' 'and 3' '' are mounted in bearing brackets 20 which are fastened to a main support 21 of the frame 1 which extends essentially horizontally. Deflection rolls 4, 4 'and 4' 'are provided between the press rolls 3. In the frame 1, a drive roller 5 for a screen press belt 22 is provided on the far left in FIG. 1. This drive roller 5 is driven by a motor, not shown.

Wie aus Fig. 1 ersichtlich, ist das Siebpreßband 22 zwischen den Preßwalzen 3 und den Umlenkwalzen 4 serpertinenartig geführt.As can be seen from FIG. 1, the screen press belt 22 is guided in a serpentine manner between the press rolls 3 and the deflection rolls 4.

Dem unterhalb der Preßwalzen 3 und Umlenkwalzen 4 zurücklaufenden Trum des Siebpreßbandes 22 ist ein die seitliche Ausrichtung des Siebpreßbandes 22 erfassender Bandfühler 6 zugeordnet. Weiters ist diesem Trum des Siebpreßbandes 22 eine Bandrichtwalze 7 zugeordnet, die im Rahmen 1 senkrecht zur Zeichnungsebene von Fig. 1 verstellbar gelagert ist. Zur Verstellung der Bandrichtwalze sind im gezeigten Ausführungsbeispiel als pneumatisch beaufschlagbare Stellglieder ausgeführte Verstellvorrichtungen vorgesehen.A band sensor 6, which detects the lateral alignment of the screen press belt 22, is assigned to the run back of the screen press belt 22 below the press rolls 3 and deflection rolls 4. Furthermore, this strand of the screen press belt 22 is assigned a belt straightening roller 7, which is adjustably mounted in the frame 1 perpendicular to the plane of the drawing in FIG. 1. In the exemplary embodiment shown, adjustment devices designed as pneumatically actuatable actuators are provided for adjusting the strip straightening roller.

Schließlich läuft das Siebpreßband 22 um eine ebenfalls durch pneumatische Federbälge 8 betätigte Bandspannvorrichtung wieder zurück zu der Maischeaufgabe 2.Finally, the screen press belt 22 runs back to the mashing task 2 around a belt tensioning device, which is also actuated by pneumatic bellows 8.

Jeder Preßwalze 3 ist noch eine Abstreifvorrichtung 9 zugeordnet, die dem sich nach oben bewegenden Abschnitt - das Siebpreßband 22 läuft in Fig. 1 im Gegenuhrzeigersinn (Pfeil 34) um - zugeordnet ist. Die Abstreifvorrichtung 9 streift an den Preßwalzen 3 allenfalls anhaftenden, zu entwässernden oder entsaftenden Stoff, z.B. Obstmaische, von den Preßwalzen 3 ab und bringt den Stoff auf das umlaufende Siebpreßband 22 zurück.Each press roll 3 is also assigned a stripping device 9, which is assigned to the section moving upward - the screen press belt 22 runs counterclockwise in FIG. 1 (arrow 34). The stripping device 9 strips off the press rolls 3 from the press rolls 3, if necessary, of any adhering, dewatered or juiced substance, and returns the material to the rotating screen press belt 22.

Die aus dem zu entwässernden Stoff ausgepreßte Flüssigkeit, im Falle von Obstmaische der Obstsaft, wird von Leiteinrichtungen gesammelt und Saftsammelwannen 11 zugeführt.The liquid squeezed out of the substance to be dewatered, in the case of fruit mash, the fruit juice, is collected by guide devices and supplied to juice collecting trays 11.

Wie in Fig. 1 angedeutet und in Fig. 2 in mehr Einzelheiten dargestellt, sind die Umlenkwalzen 4 an Trägern 30 um Achsen 31 drehbar gelagert. Die Träger 30 sind an horizontal verlaufenden, zu den Achsen 31 senkrechten Hauptträgern 21 des Rahmens 1 der Preßvorrichtung um horizontale, d.h. zu den Achsen 31 der Umlenkwalze 4 parallele Achsen 32 verschwenkbar in Lagerträgern 33 gelagert. Dabei ist die Achse 31 der Umlenkwalze 4 gegenüber der durch die Achse 32 des Trägers 30 gehenden Ebene 35 versetzt und zwar so versetzt angeordnet, daß die Achse 31 gegenüber der Ebene 35, die durch die Schwenkachse 32 der Träger 30 geht, auf der Seite angeordnet ist, die bezogen auf die Laufrichtung des Siebpreßbandes 22 (Pfeil 34 in Fig. 2) der vor der Umlenkwalze 4 angeordneten Preßwalze 3 zugekehrt ist.As indicated in FIG. 1 and shown in more detail in FIG. 2, the deflection rollers 4 are mounted on supports 30 so as to be rotatable about axes 31. The supports 30 are on horizontal main supports 21 of the frame 1 of the pressing device, which are perpendicular to the axes 31, around horizontal, i.e. to the axes 31 of the guide roller 4 parallel axes 32 pivotally mounted in bearing supports 33. The axis 31 of the deflecting roller 4 is offset from the plane 35 going through the axis 32 of the carrier 30 and is arranged so offset that the axis 31 is arranged on the side opposite to the plane 35 which goes through the pivot axis 32 of the carrier 30 which, based on the running direction of the screen press belt 22 (arrow 34 in FIG. 2), faces the press roll 3 arranged in front of the deflecting roll 4.

Dadurch ergibt sich unter der Wirkung der Spannung im Siebpreßband 22, die durch die Bandspannvorrichtung 8 erzeugt wird, ein auf die Umlenkwalze 4 einwirkendes Moment, das diese an die bezogen auf die Laufrichtung (Pfeil 34) des Siebpreßbandes 22 vor ihr angeordnete Preßwalze 3 andrückt. Das Moment entsteht dadurch, daß die Resultierende aus den vom Siebpreßband 22 auf die Umlenkwalze 4 ausgeübten Kräften auf der Seite der Schwenkachse 32 der Träger 30 liegt, die der bezogen auf die Laufrichtung des Siebpreßbandes 22 vor der Umlenkwalze 4 liegenden Preßwalze 3 benachbart ist. Durch dieses Moment wird von der Umlenkwalze 4 auf die vor ihr angeordnete Preßwalze 3 und damit auf den zu pressenden Stoff (Obstmaische) zusätzlicher Druck ausgeübt.As a result, under the effect of the tension in the screen press belt 22, which is generated by the belt tensioning device 8, a moment acting on the deflecting roller 4 presses it against the press roller 3 arranged in front of it in relation to the running direction (arrow 34) of the screen press belt 22. The moment arises from the fact that the resultant from the forces exerted by the screen press belt 22 on the deflection roller 4 lies on the side of the pivot axis 32 of the carrier 30, which is adjacent to the press roller 3 lying in front of the deflection roller 4 in relation to the running direction of the screen press belt 22. As a result of this moment, additional pressure is exerted by the deflecting roller 4 on the press roller 3 arranged in front of it and thus on the material to be pressed (fruit mash).

Wie in Fig. 1 angedeutet und in Fig. 2 in Einzelheiten dargestellt, sind die Lagerträger 33 der die Umlenkwalze 4 tragenden Träger 30 mit Hilfe von Spannschrauben 36 an den horizontal verlaufenden Hauptträgern 21 des Rahmens 1 der Vorrichtung festgeklemmt. So ist es möglich, die Stellung der Träger 30, welche die Umlenkwalze 4 tragen, zwischen benachbarten Preßwalzen 3 zu verändern und damit auch die Größe des Momentes und damit des Anpreßdruckes, mit dem die Umlenkwalze 4 über das Siebpreßband 22 auf die vor ihr angeordnete Preßwalze 3 gedrückt werden soll, auf das jeweils gewünschte Maß einzustellen. Dabei ist auch eine Stellung möglich, in der die Umlenkwalze 4 auf keine der beiden ihr benachbarten Preßwalzen 3 drückt.As indicated in FIG. 1 and shown in detail in FIG. 2, the bearing brackets 33 of the brackets 30 carrying the deflection roller 4 are clamped to the horizontally running main brackets 21 of the frame 1 of the device by means of tensioning screws 36. It is thus possible to change the position of the carriers 30, which carry the deflecting roller 4, between adjacent press rollers 3 and thus also the size of the moment and thus the contact pressure with which the deflecting roller 4 is to be pressed via the screen press belt 22 onto the press roller 3 arranged in front of it, to the respectively desired level. A position is also possible in which the deflecting roller 4 does not press on either of the two pressing rollers 3 adjacent to it.

So ist bei der in Fig. 1 gezeigten Ausführungsform beispielsweise die Umlenkwalze 4 zwischen den Preßwalzen 3 und 3' bzw. sind ihre Träger 30, genauer deren Lagerträger 33, am Teil 21 des Rahmens 1 so eingestellt, daß die Umlenkwalze 4 auf die bezogen auf die Bandlaufrichtung (Pfeil 34 in Fig. 2) - vor ihr liegende Preßwalze - weniger Druck ausübt als die Umlenkwalze 4' zwischen den Preßwalzen 3' und 3''.For example, in the embodiment shown in FIG. 1, the deflecting roller 4 is between the press rollers 3 and 3 'or its supports 30, more precisely their bearing supports 33, are set on part 21 of the frame 1 in such a way that the deflecting roller 4 is based on the tape running direction (arrow 34 in Fig. 2) - press roller lying in front of it - exerts less pressure than the deflection roller 4 'between the press rollers 3' and 3 ''.

Es ist ersichtlich, daß durch die besondere Art der Lagerung der Umlenkwalzen 4 und die Verstellbarkeit der Lagerträger 33 der Träger 30 für die Umlenkwalzen 4 der Druck, mit dem das endlose Siebpreßband 22 an die Preßwalzen 3 im Bereich des Endes der Umschlingung der Preßwalzen 3 durch das Siebpreßband 22 auf den jeweils gewünschten Wert, beispielsweise in Abhängigkeit von den Eigenschaften des Stoffes, aus dem Flüssigkeit auszupressen ist, eingestellt werden kann.It can be seen that due to the special type of storage of the deflecting rollers 4 and the adjustability of the bearing bracket 33, the carrier 30 for the deflecting rollers 4 the pressure with which the endless screen press belt 22 passes through to the press rollers 3 in the region of the end of the wrapping of the press rollers 3 the screen press belt 22 can be adjusted to the desired value, for example depending on the properties of the substance from which liquid is to be squeezed.

Auf diese Art und Weise kann durch entsprechende Einstellung der Umlenkwalzen 4 bzw. ihrer Träger 30 die Verstärkung des Anpreßdruckes des Siebpreßbandes 22 an die Preßwalzen 3 zunehmend erhöht werden, so daß auch am Beginn des Entsaftungsvorganges keine Gefahr besteht, daß noch saftreiche Obstmaische seitlich zwischen dem Siebpreßband 22 und den Preßwalzen 3 herausgedrückt wird, und dennoch ein hoher Entsaftungsgrad erreicht wird.In this way, by appropriate adjustment of the deflecting rollers 4 or their carrier 30, the increase in the contact pressure of the screen press belt 22 to the press rollers 3 can be increased increasingly, so that even at the beginning of the juicing process there is no danger that juicy fruit mash will laterally between the Screen press belt 22 and the press rollers 3 is pressed out, and yet a high degree of juicing is achieved.

Zusammenfassend kann die Erfindung beispielsweise wie folgt dargestellt werden:
Bei einer Saftbandpresse zum Entsaften von Obstmaische wird ein endloses Siebpreßband 22 serpentinenartig zwischen Preßwalzen 3 und zwischen den Preßwalzen 3 angeordneten Umlenkwalzen 4 geführt. Die Umlenkwalzen 4 sind über Träger 30 und Lagerträger 33 im Rahmen 1 der Vorrichtung um Schwenkachsen 32 verschwenkbar gelagert. Die Lagerträger 33 der Träger 30 für die Umlenkwalzen 4 sind verstellbar, so daß der Abstand der Resultierenden aus den vom Siebpreßband 22 auf die Umlenkwalze 4 ausgeübten Kräfte zur Schwenkachse 32 der Träger 30 geändert werden kann. Auf diese Art und Weise kann die Größe des Momentes, durch das die Umlenkwalze 4 auf die eine oder andere der benachbarten Preßwalzen 3 gedrückt wird, auf den jeweils günstigsten Wert eingestellt werden, um den Anpreßdruck zwischen Siebpreßband 22 und Preßwalze 3 am Ende eines Umschlingungsbereiches zwischen Siebpreßband 22 und Preßwalze 3 zu erhöhen.In summary, the invention can be represented as follows, for example:
In a juicer press for juicing fruit mash, an endless screen press belt 22 is guided in a serpentine manner between press rolls 3 and deflection rolls 4 arranged between press rolls 3. The deflection rollers 4 are on carrier 30 and Bearing bracket 33 is pivotally mounted in frame 1 of the device about pivot axes 32. The bearing supports 33 of the supports 30 for the deflecting rollers 4 are adjustable so that the distance of the resultant from the forces exerted by the screen press belt 22 on the deflecting roller 4 to the pivot axis 32 of the supports 30 can be changed. In this way, the magnitude of the moment by which the deflecting roller 4 is pressed onto one or the other of the adjacent press rollers 3 can be adjusted to the most favorable value in order to adjust the contact pressure between the screen press belt 22 and the press roller 3 at the end of a wrap area Screen press belt 22 and press roll 3 to increase.

Bei der erfindungsgemäßen Vorrichtung ergibt sich noch der Vorteil, daß an der den Preßwalzen 3 gegenüberliegenden Seite des Siebpreßbandes 22 an diesem anhaftende Flüssigkeit durch die Umlenkwalzen 4 abgestreift wird, bevor noch der Stoff (z.B. die Obstmaische) entlastet wird. So wird verhindert, daß Flüssigkeit vom Stoff, wenn er am Ende des Bereiches, in dem die Preßwalzen 3 vom Siebpreßband 22 umschlungen sind, wieder aufgesaugt wird.In the device according to the invention, there is also the advantage that on the side of the screen press belt 22 opposite the press rolls 3, liquid adhering to it is stripped off by the deflection rolls 4 before the material (e.g. the fruit mash) is relieved. This prevents liquid from being sucked up from the material when it is sucked up again at the end of the area in which the press rolls 3 are wrapped by the screen press belt 22.
