Description

Die Erfindung betrifft eine Wein- und Fruchtpresse zum Abpressen von Trauben, Obstmaische und anderen mit Flüssigkeit durchsetzten Stoffen.The invention relates to a wine and fruit press for pressing grapes, fruit mash and other substances interspersed with liquid.

Die Erfindung geht aus von einem Stand der Technik, wie er in der NL-C-101 977 gegeben ist. Dort ist eine Presse der oben angegebenen Art beschrieben, bei der innerhalb eines gelochten Siebmantels koaxial eine Presseinrichtung angeordnet ist, die aus einem im Querschnitt dreistrahligen Stern besteht, der mit einem elastischen Schlauch überzogen ist. In das Innere des Schlauches ist ein Druckmittel einbringbar, das den elastischen Schlauch, d.h. die Membrane, nach außen aufweitet und dabei das Pressgut gegen den Siebmantel drückt.The invention is based on a prior art, as given in NL-C-101 977. There, a press of the type specified above is described, in which a pressing device is arranged coaxially within a perforated screen jacket, which consists of a star with three rays in cross section, which is covered with an elastic tube. A pressure medium can be introduced into the interior of the hose, which pressurizes the elastic hose, i.e. the membrane, expands outwards and presses the material to be pressed against the screen jacket.

Zur Verwendung in der Praxis ist eine Presse, z.B. für Weintrauben, nach diesem Stand der Technik jedoch weitgehend ungeeignet. Die Presse ist mit ihrer Mittelachse vertikal angeordnet, was ein Beschicken und Entleeren der zwischen den drei Flügeln ausgebildeten Presskammern über Gebühr erschwert und außerdem das jeweils nötige Auflockern und Krümeln der Maische unmöglich macht.A press, e.g. for grapes, but largely unsuitable according to this state of the art. The press is arranged vertically with its central axis, which makes loading and emptying the press chambers formed between the three wings unduly difficult and also makes the loosening and crumbling of the mash necessary in each case impossible.

Der Siebmantel besitzt auch keinerlei Öffnungen, durch welche hindurch ein Zugang zu den Presskammern gegeben wäre Ferner sind Presseinrichtung und Siebmantel nicht relativ zueinander verdrehbar, und es ist auch keinerlei Abstreifvorrichtung vorgesehen, um etwa innen am Siebmantel haftendes, ausgepresstes Gut abstreifen zu können.The screen jacket also has no openings through which access to the press chambers would be provided. Furthermore, the pressing device and screen jacket cannot be rotated relative to one another, and no stripping device is provided in order to be able to strip pressed material that is adhering to the inside of the screen jacket.

Dies ist ein besonders wesentlicher Nachteil, da man Obst und vor allem Weintrauben, nicht einfach einmal gegen die Wand pressen kann. Es muß vielmehr das Preßgut immer wieder aufgelockert und zerkrümelt werden, um dann wieder neu gepreßt zu werden. Dieser Vorgang muß innerhalb einer Charge bis zu 30mal wiederholt werden.This is a particularly important disadvantage, since you cannot simply press fruit and especially grapes against the wall. Rather, the material to be pressed has to be loosened and crumbled again and again in order to then be pressed again. This process must be repeated up to 30 times within a batch.

Der Erfindung liegt die Aufgabe zugrunde, alle diese Nachteile zu überwinden und eine Presse anzugeben, die in der Praxis wesentlich besser verwendbar ist.The invention has for its object to overcome all these disadvantages and to provide a press that can be used much better in practice.

Diese Aufgabe ist durch eine Presse gelöst, welche die in Anspruche 1 angegebenen Merkmale aufweist.This object is achieved by a press which has the features specified in claim 1.

Wesentliche Merkmale der erfundenen Presse sind, daß die gesamte Presse mit ihrer Achse horizontal angeordnet ist, daß ferner die Presseinrichtung und der Siebmantel relativ zueinander drehbar sind, und daß der Siebmantel mit einer Einfüllöffnung versehen ist. Außerdem ist an mindestens einem der Flügel eine Abstreifvorrichtung angebracht.Essential features of the invented press are that the entire press is arranged horizontally with its axis, that the pressing device and the screen jacket are rotatable relative to one another, and that the screen jacket is provided with a filling opening. In addition, a stripping device is attached to at least one of the wings.

Der besondere Vorteil der erfundenen Presse gegenüber der Presse nach dem Stand der Technik ist die leichte Zugänglichkeit der einzelnen Kammern durch die Einfüllöffnung hindurch. Diese ist zu Reinigungszwecken unbedingt erforderlich. Es wird damit erreicht, daß sämtliche Innenräume und Flächen zugänglich, d.h. durch Personal begehbar sind. Da es sich um lebensmittelverarbeitende Maschinen handelt und die Verhinderung von Mikrobakterien eine grundsätzliche Voraussetzung darstellt, ist diese unbedingt erforderlich. Diese Zugänglichkeit ist nur gewährleistet, wenn - gemäß dem einen Erfindungsmerkmal - die Presseinrichtung und der Siebmantel relativ zueinander drehbar sind.The particular advantage of the invented press compared to the press according to the prior art is the easy accessibility of the individual chambers through the filling opening. This is absolutely necessary for cleaning purposes. This ensures that all interiors and surfaces are accessible, i.e. are accessible by personnel. Since it is a food processing machine and the prevention of microbacteria is a basic requirement, this is essential. This accessibility is only guaranteed if - according to one feature of the invention - the pressing device and the screen casing can be rotated relative to one another.

Durch die an mindestens einem Flügel angebrachte Abstreifvorrichtung wird durch die sich drehenden Flügel der Presseinrichtung eine sehr gute Krümelung erreicht. Diese Krümelung erfordert auch keinerlei Aufwand im Sinne der Unfallverhügungsvorschriften der Berufsgenossenschaft, da die Krümelung nicht durch die rotierende Trommel erfolgen muß, sondern durch Drehung des Flügels im geschlossenen und stehenden System geschieht.Due to the stripping device attached to at least one wing, very good crumbling is achieved by the rotating wings of the pressing device. This crumbling does not require any effort in the sense of the accident prevention regulations of the professional association, since the crumbling does not have to be done by the rotating drum, but by rotating the wing in the closed and standing system.

Ferner kann die erfundene Presse mit einfachen Mitteln für vollautomatische Arbeitsweise ausgerüstet werden.Furthermore, the invented press can be equipped with simple means for fully automatic operation.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown in one embodiment.

Die Figur zeigt den Querschnitt des Behälters mit der 3-Flügel-Pressmembrane. Der Behälter ist als zylinderförmiger Siebmantel 1 auf der Achse 4 eines Maschinengestelles gelagert. Auf dieser Achse ist auch der 3-Flügler bzw. das Sternkreuz 2 gelagert. Die Lagerung erfolgt in der Weise, daß eine Drehung von Siebmantel und 3-Flügler unabhängig voneinander möglich ist. Hierbei kann die Drehung von Siebmantel und 3-Flügler sowohol synchron wie auch asynchron erfolgen; auch ist Gegenlauf möglich.The figure shows the cross section of the container with the 3-wing press membrane. The container is mounted as a cylindrical screen jacket 1 on the axis 4 of a machine frame. The 3-wing aircraft or the star cross 2 is also mounted on this axis. The storage takes place in such a way that rotation of the screen jacket and 3-wing is possible independently of one another. Here, the rotation of the screen jacket and 3-wing can be done both synchronously and asynchronously; counter-rotation is also possible.

Die freien Enden des 3-Flüglers bzw. Sternkreuzes 2 sind mit einer elastischen Pressmembrane 3 verbunden. Beispielsweise kann diese Pressmembrane aus einem Gummischlauch bestehen, der über den 3-Flügler gezogen ist, und der jeweils auf der Stirnseite der Flügel festgemacht ist. Es wäre allerdings auch vorstellbar, daß der Gummischlauch auf den Flügelstirnseiten nur lose aufliegt.The free ends of the 3-wing or star cross 2 are connected to an elastic press membrane 3. For example, this press membrane can consist of a rubber hose, which is pulled over the 3-wing, and which is attached to the front of the wing. However, it would also be conceivable that the rubber tube only lies loosely on the wing end faces.

Die Befüllung des Behälters erfolgt über eine Einfüllöffnung 8, die als Mannloch oder Tür ausgebildet ist.The container is filled via a filling opening 8, which is designed as a manhole or door.

Hierbei ist über ein Vakuumgebläse die elastische Pressmembrane 3 auf den 3-Flügler aufgezogen. Über einen Drucklufterzeuger wird Druckluft 6 in genügender Menge zwischen 3-Flügler 2 und elastische Pressmembrane 3 gebracht. Hierbei zeigt die strichliniierte Linie 3a die aufgeblähte elastische Pressmembrane. Diese Pressmembrane 3a drückt die Maische 5 oder einen anderen mit Flüssigkeit durchsetzten Stoff an die durchlässige Wand des Siebmantels 1.In this case, the elastic press membrane 3 is drawn onto the 3-wing unit by means of a vacuum blower. A sufficient amount of compressed air 6 is brought between 3-wing 2 and elastic press membrane 3 via a compressed air generator. The dashed line 3a shows the inflated elastic press membrane. This press membrane 3 a presses the mash 5 or another liquid-permeated substance against the permeable wall of the screen casing 1.

Dabei sind zwei Ausführungsvarianten der Presse möglich. Erstens kann, wie in der Zeichnung dargestellt, mittels Siebbehälter mit freiem Auslauf in eine entsprechende Saftwanne 9 gesiebt werden. Es kann aber auch ein Behälter mit Doppelwandung verwendet werden, d.h. innen der Siebmantel und außen ein geschlossener Zylinder, in den gesiebt wird, um eine geringere Oxydation des Saftes zu erreichen.Two versions of the press are possible. First, as shown in the drawing, can be sieved into a corresponding juice pan 9 by means of a sieve container with a free outlet. A double-walled container can also be used, i.e. inside the sieve jacket and outside a closed cylinder into which sieving is carried out in order to achieve less oxidation of the juice.

Durch die Schnelligkeit der Pressung und Saftgewinnung gegenüber den bekannten Pressen, tritt eine Oxydation aber beim eigentlichen Pressvorgang kaum auf. Eine Presse mit Doppelmantel ist somit nur als Sonderausführung anzusehen. Da der Presskuchen dünner ist und schon bei der ersten Pressung mehr Saft abläuft, ist eine so häufige Krümelung wie bei Tankpressen, nicht erforderlich. Die Krümelvorrichtung 7 ist ein auf dem 3-Flügler montierter Abstreifer. Die Krümelung erfolgt über den 3-Flügler 2. Hierbei dreht sich dieser um seine Achse 4, während der Siebmantel 1 arretiert ist. Lediglich zum Entleeren der Maschine, d.h. zum Tresteraustrag wird der Siebmantel 1 um 180° gedreht, so daß die Einfüllöffnung 8 nach unten zeigt. Bei einer anderen Ausführungsform könnte der Siebmantel 1 mit einer zweiten Tür versehen sein.Due to the speed of pressing and juice extraction compared to the known presses, oxidation hardly occurs during the actual pressing process. A press with a double jacket is therefore only to be regarded as a special version. Since the press cake is thinner and more juice runs off the first time it is pressed, it is not necessary to crumble as frequently as with tank presses. The crumbling device 7 is a scraper mounted on the 3-wing. The crumbling takes place via the 3-wing 2. This rotates about its axis 4, while the screen jacket 1 is locked. Only for emptying the machine, i.e. to remove the pomace, the screen jacket 1 is rotated by 180 °, so that the filling opening 8 points downward. In another embodiment, the screen jacket 1 could be provided with a second door.
