Definitions
- the invention relates to a device for processing tissue parts, in particular animal and / or vegetable nature, to sausage meat, granules, etc. by crushing and / or mixing by means of a cutter using a cryogenic liquefied gas with a rotating around a substantially vertical rotary shaft Bowl for receiving the tissue parts, into which rotating knives seated on a horizontal rotating shaft are immersed, whereby the bowl can be covered by a movable cover which is connected to a rotating shaft attached to the cutter via a lifting device and has an opening for escaping gas.
- a cutting machine which is called “cutting mixer” or “cutter” is usually used to process fabric parts into sausage meat, granules, etc.
- a cutter for example, meat parts are crushed into sausage meat or cocoa pods into a base for chocolate production and mixed.
- the tissue parts to be processed in particular of animal and / or vegetable nature, are placed in a bowl rotating in a machine frame.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Verarbeitung von Gewebeteilen, insbesondere tierischer und/oder pflanzlicher Natur, zu Brät, Granulat, etc. durch Zerkleinern und/oder Mischen mittels eines Kutters unter Anwendung eines tiefkalten verflüssigten Gases mit einer sich um eine im wesentlichen vertikale Drehwelle drehenden Schüssel zur Aufnahme der Gewebeteile, in welche auf einer horizontalen Drehwelle sitzende rotierende Messer eintauchen, wobei die Schüssel durch einen beweglichen Deckel abdeckbar ist, der über eine Hebevorrichtung mit einer am Kutter angebrachten Drehwelle in Verbindung steht und eine Öffnung für austretendes Gas aufweist.The invention relates to a device for processing tissue parts, in particular animal and / or vegetable nature, to sausage meat, granules, etc. by crushing and / or mixing by means of a cutter using a cryogenic liquefied gas with a rotating around a substantially vertical rotary shaft Bowl for receiving the tissue parts, into which rotating knives seated on a horizontal rotating shaft are immersed, whereby the bowl can be covered by a movable cover which is connected to a rotating shaft attached to the cutter via a lifting device and has an opening for escaping gas.
Zur Verarbeitung von Gewebeteilen zu Brät, Granulat, etc. benutzt man üblicherweise eine Schneidmaschine, die "Schneidmischer" oder "Kutter" genannt wird. In einem Kutter werden beispielsweise Fleischteile zu Wurstbrät oder Kakaofrüchte zu einer Grundmasse für die Schokoladenherstellung zerkleinert und gemischt. Die zu verarbeitenden Gewebeteile, insbesondere tierischer und/oder pflanzlicher Natur, werden hierzu bekanntermaßen in eine in einem Maschinengestell rotierende Schüssel gegeben. Die Schüssel steckt auf einer vertikalen Drehwelle, die z.B. von einem Elektromotor angetrieben wird.A cutting machine, which is called "cutting mixer" or "cutter", is usually used to process fabric parts into sausage meat, granules, etc. In a cutter, for example, meat parts are crushed into sausage meat or cocoa pods into a base for chocolate production and mixed. As is known, the tissue parts to be processed, in particular of animal and / or vegetable nature, are placed in a bowl rotating in a machine frame. The bowl is placed on a vertical rotary shaft, which is driven by an electric motor, for example.
Durch diese rotierende Schüssel werden die Gewebeteile in einem Schneidraum, in welchem ein schnellrotierender Messerkopf läuft, transportiert. Durch mehrmaliges Durchführen der Gewebeteile durch den Schneidraum werden diese zerkleinert und durchmischt.Through this rotating bowl, the tissue parts are transported in a cutting room in which a rapidly rotating cutter head runs. By repeatedly passing the tissue parts through the cutting space, they are crushed and mixed.
Üblicherweise ist die Kutterschüssel mit einem Schallschutzdeckel abdeckbar, der von Zeit zu Zeit geöffnet werden muß, um z.B. Rohstoffe zuzugeben oder fertiges Produkt zu entnehmen.Usually the cutter bowl can be covered with a soundproof cover, which has to be opened from time to time, e.g. Add raw materials or take finished product.
Die Einbringung mechanischer Energie durch die rotierenden Messer ist zwangsläufig mit einem Temperaturanstieg der zu zerkleinernden Gewebeteile verbunden. Dies ist jedoch gerade bei der Verarbeitung tierischer oder pflanzlicher Gewebeteile unerwünscht, da z.B. Fette bei den hierbei erreichbaren Temperaturen schmelzen und Denaturierungen an Eiweißteilen auftreten können. Außerdem sollen die Gewebeteile oft auch bereits während des Zerkleinerungsvorgangs tiefgekühlt und konserviert werden.The introduction of mechanical energy by the rotating knives is inevitably associated with an increase in temperature of the tissue parts to be shredded. However, this is undesirable especially when processing animal or vegetable tissue parts, since e.g. Melt fats at the temperatures that can be reached and denaturations on protein parts can occur. In addition, the tissue parts should often be deep-frozen and preserved during the shredding process.
Daher wird üblicherweise ein Kältemittel in die Kutterschüssel eingeleitet. So beschreibt die DE-A-33 44 521 einen Kutter, bei dem zur Ableitung der von den rotierenden Messer erzeugten Reibungswärme flüssiger Stickstoff mittels einer Sprühdüse direkt auf die Messer gesprüht wird.Therefore, a refrigerant is usually introduced into the cutter bowl. For example, DE-A-33 44 521 describes a cutter in which liquid nitrogen is sprayed directly onto the knives by means of a spray nozzle in order to remove the frictional heat generated by the rotating knives.
Beim Einsatz flüssiger Gase, wie z.B. flüssigen Stickstoffs, Kohlendioxid etc., zum Kühlen von im Kutter zu behandelnden Produkten bzw. zum Abführen von durch die Messer erzeugter Reibungswärme entsteht ein kaltes Abgas, das schon aus Sicherheitsgründen entfernt werden muß, da sonst z.B. Erstickungsgefahr für Betriebspersonal besteht oder Sichtbehinderungen durch Nebelbildung (kondensierter H20-Dampf) auftreten.When using liquid gases, such as liquid nitrogen, carbon dioxide etc., to cool products to be treated in the cutter or to remove frictional heat generated by the knives, a cold exhaust gas is generated, which must be removed for safety reasons, otherwise there is a risk of suffocation, for example Operating personnel exist or visibility is impaired due to the formation of fog (condensed H20 vapor).
Es ist bekannt, das durch eine Öffnung im Schallschutzdeckel des Kutters austretende kalte Abgas über einen Ventilator abzusaugen. Die Öffnung im Schallschutzdeckel und der Ventilator sind über eine flexible Absaugleitung, z.B. einen Kunststoffschlauch, verbunden. Bei Öffnung des Schallschutzdeckels muß sich die Absaugleitung zwangsläufig mitbewegen, bzw. wird diese von dem Deckel abgekoppelt. Die flexible Absaugleitung wird während des Absaugens des kalten Abgases jedoch soweit abgekühlt, daß diese ihre Flexibilität verliert und damit bei Bewegungen bricht, deren Durchführung Flexibilität voraussetzen.It is known to suck off the cold exhaust gas emerging through an opening in the soundproof cover of the cutter via a fan. The opening in the soundproof cover and the fan are connected via a flexible suction line, e.g. a plastic tube connected. When the soundproof cover is opened, the suction line must inevitably move with it, or it is uncoupled from the cover. However, the flexible suction line is cooled to such an extent during the suction of the cold exhaust gas that it loses its flexibility and thus breaks during movements which require flexibility to be carried out.
Die flexible Absaugleitung kann also beim Öffnen des Schallschutzdeckels leicht brechen, wenn sie sich beim Öffnen mit dem Deckel mitbewegt. Andererseits ist das Abkoppeln der Absaugleitung bei jedem Öffnen des Deckels umständlich, zeitaufwendig und ebenfalls mit Brandgefahr verbunden.The flexible suction line can break easily when opening the soundproof cover if it moves with the cover when opening. On the other hand, uncoupling the suction line each time the lid is opened is cumbersome, time-consuming and also involves a risk of fire.
Es ist auch bekannt, über dem Kutter eine Absaughaube zu installieren, über die austretendes Abgas durch einen Ventilator abgesaugt wird. Dies ist jedoch oft aus Platzgründen nicht möglich. Außerdem bildet sich an der Absaughaube Kondensat, das in die Kutterschüssel tropft und die Behandlung der Gewebeteile nachteilig beeinflußt.It is also known to install a suction hood over the cutter, through which exhaust gas is sucked off by a fan. However, this is often not possible due to space constraints. In addition, condensate forms on the suction hood, which drips into the cutter bowl and adversely affects the treatment of the tissue parts.
Die bekannten Methoden zum Absaugen von kaltem Abgas weisen also verschiedene Nachteile auf, wie hohen Verschleiß durch Brechen von Absaugleitungen, Kondensatbildung oder Umständlichkeit und hohen Zeitaufwand.The known methods for extracting cold exhaust gas therefore have various disadvantages, such as high wear and tear due to the breakage of extraction lines, the formation of condensate or laboriousness and a great deal of time.
Aufgabe der vorliegenden Erfindung ist es daher, eine Vorrichtung der eingangs genannten Art so auszugestalten, daß die genannten Nachteile nicht auftreten.The object of the present invention is therefore to design a device of the type mentioned at the outset so that the disadvantages mentioned do not occur.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an der mit dem Deckel in Verbindung stehenden Drehwelle in axialer Richtung der Drehwelle eine Rohr fest angebracht ist, daß das Rohr an seinem der Drehwelle gegenüberliegenden Ende in einer Öffnung eines feststehenden Kastens drehbar gelagert ist, daß die Öffnung im Deckel mit einer Öffnung im Rohr über eine Verbindungsleitung verbunden ist und daß eine weitere Öffnung im feststehenden Kasten mit einer Absaugvorrichtung verbunden ist.This object is achieved in that a tube is fixedly attached to the rotary shaft connected to the cover in the axial direction of the rotary shaft, that the tube is rotatably supported at its end opposite the rotary shaft in an opening of a fixed box, that the opening is connected in the lid to an opening in the tube via a connecting line and that another opening in the fixed box is connected to a suction device.
Üblicherweise ist die Kutterschüssel mit einem Schallschutzdeckel abdeckbar. Dieser Schallschutzdeckel steht über eine Hebevorrichtung mit einer am Maschinengestell des Kutters angebrachten Drehwelle in Verbindung. Als Hebevorrichtung kann z.B. eine starre Verbindung dienen, die den Deckel beim Drehen der Drehwelle anhebt und somit die Kutterschüssel öffnet.The cutter bowl can usually be covered with a soundproof cover. This soundproof cover is connected to a rotary shaft attached to the machine frame of the cutter via a lifting device. As a lifting device e.g. serve a rigid connection that lifts the lid when turning the rotating shaft and thus opens the cutter bowl.
Erfindungsgemäß ist an der mit dem Deckel in Verbindung stehenden Drehwelle ein Rohr in axialer Richtung der Drehwelle fest angebracht. Das Rohr endet auf der der Drehwelle abgewandten Seite in einer Öffnung eines feststehenden Kastens und kann sich frei im feststehenden Kasten drehen. Die im Schallschutzdeckel angebrachte Öffnung für das Abgas ist über eine Verbindungsleitung mit einer im Rohr befindlichen seitlichen Öffnung verbunden. Über diese Verbindungsleitung kann also Abgas aus der Kutterschüssel in das Rohr übertreten.According to the invention, a tube is fixedly attached to the rotary shaft connected to the cover in the axial direction of the rotary shaft. The tube ends on the side facing away from the rotating shaft in an opening of a fixed box and can rotate freely in the fixed box. The opening for the exhaust gas in the soundproof cover is connected via a connecting line to a side opening in the pipe. Exhaust gas from the cutter bowl can therefore pass into the pipe via this connecting line.
Der feststehende Kasten weist eine zweite Öffnung auf, die mit einer Absaugvorrichtung in Verbindung steht. Das Abgas wird also beim Betrieb der Absaugvorrichtung durch die im Schallschutzdeckel befindliche Öffnung über die Verbindungsleitung in das Rohr geleitet. Im Rohr wird das Abgas zum feststehenden Kasten und von dort zur Absaugvorrichtung geführt.The fixed box has a second opening which is connected to a suction device. When the suction device is in operation, the exhaust gas is thus conducted into the pipe through the opening in the soundproofing cover and via the connecting line. In the pipe, the exhaust gas is led to the fixed box and from there to the suction device.
Wird der Deckel durch Drehen der mit dem Deckel über die Hebevorrichtung in Verbindung stehenden Drehwelle geöffnet, so dreht sich das auf der Drehwelle sitzende Rohr mit. Ebenso dreht sich die Verbindungsleitung zwischen der Öffnung im Deckel und der seitlichen Öffnung im Rohr mit, so daß sich die Verbindungsleitung beim Öffnen des Deckels nicht verbiegt. Das Rohr dreht sich in der einen Öffnung des feststehenden Kastens, während die andere Öffnung des Kastens fest mit der Absaugvorrichtung verbunden ist. Durch die erfindungsgemäße Vorrichtung wird also ein Brechen der durch das kalte Abgas weit abgekühlten und unflexibel gewordenen Verbindungsleitung vermieden.If the cover is opened by rotating the rotary shaft connected to the cover via the lifting device, the tube sitting on the rotary shaft also rotates. The connecting line between the opening in the lid and the lateral opening in the tube also rotates, so that the connecting line does not bend when the lid is opened. The tube rotates in one opening of the fixed box, while the other opening of the box is firmly connected to the suction device. The device according to the invention thus prevents the connecting line, which has been cooled down by the cold exhaust gas and has become inflexible, from breaking.
Zweckmäßigerweise ist die Absaugvorrichtung als Ventilator ausgebildet. Der Ventilator saugt das kalte Abgas aus der Kutterschüssel durch die im Deckel befindliche Öffnung über die mit der seitlichen Öffnung des Rohres verbundene Verbindungsleitung in das Rohr, von dort in den feststehenden Kasten und schließlich zum Ventilator.The suction device is expediently designed as a fan. The fan sucks the cold exhaust gas out of the cutter bowl through the opening in the lid, through the connecting line connected to the side opening of the pipe, into the pipe, from there into the fixed box and finally to the fan.
Die erfindungsgemäße Vorrichtung ist einfach und preiswert. Ein üblicher Kutter kann durch Montage weniger Teile, nämlich Verbindungsleitung, Rohr, feststehender Kasten und Absaugvorrichtung, zur erfindungsgemäßen Vorrichtung umgebaut werden.The device according to the invention is simple and inexpensive. A conventional cutter can be converted to the device according to the invention by installing fewer parts, namely connecting line, pipe, fixed box and suction device.
Die erfindungsgemäße Vorrichtung weist ferner den Vorteil auf, daß die Verbindungsleitung nicht bei jedem Öffnen des Kutterdeckels abgenommen werden muß. Umständliche und zeitaufwendige Nebenarbeiten beim Betrieb des Kutters werden dadurch vermieden.The device according to the invention also has the advantage that the connecting line does not have to be removed each time the cutter cover is opened. Cumbersome and time-consuming additional work during the operation of the cutter is avoided.
Außerdem tritt bei der erfindungsgemäßen Vorrichtung nicht der mit üblichen Methoden zum Absaugen von kaltem Abgas aus einem Kutter verbundene hohe Verschleiß durch Brechen von abgekühlten und unflexibel gewordenen Absaugleitungen auf. Die erfindungsgemäße Vorrichtung ist nämlich gar nicht auf die Flexibilität der Verbundungsleitung zwischen der Öffnung im Deckel und der seitlichen Öffnung im drehbaren Rohr angewiesen. Es kann auch eine starre Verbindungsleitung verwendet werden.In addition, the high wear associated with conventional methods of extracting cold exhaust gas from a cutter does not occur in the device according to the invention due to the breaking of cooled and inflexible extraction lines. The device according to the invention is not dependent on the flexibility of the connecting line between the opening in the lid and the lateral opening in the rotatable tube. A rigid connecting line can also be used.
Ferner tritt bei der erfindungsgemäßen Vorrichtung keine Kondensatbildung auf, die den ordnungsgemäßen Betrieb des Kutters stören würde.Furthermore, no condensate formation occurs in the device according to the invention, which would interfere with the proper operation of the cutter.
Die erfindungsgemäße Vorrichtung kann zur Verarbeitung von Gewebeteilen, insbesondere von tierischen und/oder pflanzlichen Gewebeteilen, unter Zufuhr eines tiefkalten verflüssigten Gases zu Brät, Granulat etc. angewendet werden. Beispiele hierfür sind die Herstellung von Brühwurstbrät und Rohwurstbrät durch Zerkleinern von Fleischteilen in der erfindungsgemäßen Vorrichtung und das Zerkleinern und Mischen von frischem Speck ("Körnen"). Allgemein eignet sich die erfindungsgemäße Vorrichtung zum Mengen, Mischen und Zerkleinern von geeigneten Stoffen aller Art, wie z.B. Nüssen, Geflügelfedern in Tierverwertungsanstalten, Plastik- und Gummiteilen unter Verwendung eines tiefkalten verflüssigten Gases.The device according to the invention can be used for processing tissue parts, in particular animal and / or vegetable tissue parts, with supply of a cryogenic liquefied gas to sausage meat, granules, etc. Examples of this are the production of scalded sausage meat and raw sausage meat by chopping meat parts in the device according to the invention and the chopping and mixing of fresh bacon ("grains"). In general, the device according to the invention is suitable for the quantity, mixing and comminution of suitable substances of all kinds, such as e.g. Nuts, poultry feathers in animal processing plants, plastic and rubber parts using a cryogenic liquefied gas.
Im folgenden sei die Erfindung anhand eines in einer schematischen Zeichnung dargestellten Ausführungsbeispiels näher erläutert:The invention is explained in more detail below with reference to an exemplary embodiment shown in a schematic drawing:
Die Figur zeigt einen erfindungsgemäßen Kutter in der Draufsicht.The figure shows a cutter according to the invention in plan view.
Der in der Figur dargestellte Kutter besitzt eine Kutterschüssel 1, die um eine senkrechte Achse 2 drehbar ist und von einem nicht dargestellten Elektromotor angetrieben werden kann. Vertikal zur Kutterschüsselebene ist ein drehbarer Messersatz 3 angeordnet, dessen horizontale Achse 4 oberhalb des Randes der Schüssel 1 liegt. Der Messersatz 3 kann über die Achse 4 von einem nicht dargestellten Elektromotor angetrieben werden. Über eine nicht dargestellte Düse wird flüssiger Stickstoff auf die in der Schüssel 1 befindlichen Gewebeteile aufgesprüht. Die Kutterschüssel 1 ist in einem Maschinengestell 6 drehbar aufgehängt.The cutter shown in the figure has a cutter bowl 1, which is rotatable about a vertical axis 2 and can be driven by an electric motor, not shown. A rotatable knife set 3 is arranged vertically to the cutter bowl level, the horizontal axis 4 of which lies above the edge of the bowl 1. The knife set 3 can be driven via the axis 4 by an electric motor, not shown. Liquid nitrogen is sprayed onto the tissue parts located in the bowl 1 via a nozzle (not shown). The cutter bowl 1 is rotatably suspended in a
Der Kutter ist durch einen beweglichen Schallschutzdeckel 7 abdeckbar, der eine Öffnung 8 für austrendes kaltes Abgas aufweist. Der Deckel 7 ist über eine Hebevorrichtung 9, die beim Ausführungsbeispiel als starre Verbindung ausgebildet ist, mit einer am Maschinengestell 6 angebrachten horizontalen Drehwelle 10 verbunden. Auf der Drehwelle 10 sitzt ein Rohr 11, das in einer Öffnung 12 eines feststehenden Kastens 13 endet. Die Öffnung 8 im Deckel 7 ist über eine Verbindungsleitung 14 mit einer seitlichen Öffnung 15 des Rohres 11 verbunden. Der feststehende Kasten 13 weist eine zweite Öffnung 16 auf, die mit einem nicht dargestellten Ventilator in Verbindung steht.The cutter can be covered by a movable soundproof cover 7, which has an opening 8 for escaping cold exhaust gas. The cover 7 is connected via a lifting device 9, which in the exemplary embodiment is designed as a rigid connection, to a horizontal
Beim Betrieb des Ventilators wird Abgas aus dem Kutter durch die Öffnung 8 im Deckel 7 über die Verbindungsleitung 14 durch die Öffnung 15 in das Rohr 11, weiter durch die Öffnung 12 in den feststehenden Kasten 13 und schließlich durch die Öffnung 16 zum Ventilator gesaugt.When the fan is operating, exhaust gas is sucked from the cutter through the
Zum Öffnen des Deckels 7 wird durch Drehen der Drehwelle 10 der Deckel 7 durch die Hebevorrichtung 9 angehoben. Dabei drehen sich das auf der Drehwelle 10 sitzende Rohr 11 und die Verbindungsleitung 14 zwischen der Öffnung 8 des Deckels 7 und der Öffnung 15 des Rohres 11 mit. Ein Verbiegen der Verbindungsleitung 14 wird dadurch vermieden, so daß auch eine starre Verbindungsleitung verwendet werden kann.To open the cover 7, the cover 7 is raised by the lifting device 9 by rotating the
Bei der herkömmlichen Methode der Abgasabsaugung aus dem Kutter wird eine an der Öffnung 8 des Deckels 7 angebrachte flexible Abgasleitung verwendet, die sich beim Öffnen des Deckels 7 verbiegt. Die Abgasleitung kühlt sich durch das durch sie hindurchtretende kalte Abgas stark ab, so daß sie ihre Flexibilität verliert und bei Verbiegungen leicht bricht. Dagegen wird ein Verbiegen der Verbindungsleitung 14, durch die das kalte Abgas aus dem Kutter abgezogen wird, bei der erfindungsgemäßen Vorrichtung vermieden, so daß ein Brechen der Verbindungsleitung 14 verhindert wird.In the conventional method of exhaust gas extraction from the cutter, a flexible exhaust gas line which is attached to the
Bei der erfindungsgemäßen Vorrichtung kann jederzeit der Kutterdeckel 7 bei Bedarf geöffnet werden, ohne daß umständliche Nebenarbeiten zum Abkoppeln der Absaugleitung für das Abgas erforderlich wären..In the device according to the invention, the cutter cover 7 can be opened at any time if necessary, without any cumbersome additional work for uncoupling the suction line for the exhaust gas.
