Definitions
- the invention relates to a device for processing tissue parts, in particular animal and / or vegetable nature, into sausage meat, granules, etc. by comminuting and / or mixing by means of a cutting mixer using cryogenic liquefied gas, with a rotating around a substantially vertical rotary shaft Bowl for holding the tissue parts, into which rotating knives seated on a horizontal rotary shaft are immersed, at least the knives being coverable by a lid, with a storage tank for cryogenic liquefied gas, a supply line for liquefied gas connected to this and one at the other end spray nozzle attached to the supply line.
- 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 cut into sausage meat or cocoa fruits into a base for chocolate production and mixed.
- the tissue parts to be processed in particular 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.
- 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.
- tissue parts to be shredded.
- 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.
- the tissue parts should often be deep-frozen and preserved during the shredding process.
- DE-OS 33 44 521 it is proposed to spray liquid nitrogen directly onto the knife by means of a spray nozzle in order to derive the frictional heat generated by the rotating knife.
- a cutter is proposed in which a spray nozzle is arranged at a short distance from the knife and is directed towards the knife.
- the spray nozzle for the liquid nitrogen is arranged in the knife chamber and comes into contact with the tissue parts whirled up by the knife.
- 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.
- This object is achieved in that the spray nozzle in the direction of rotation of the bowl in front of the knife immersed in the tissue parts above the tissue parts and is directed to a position in the direction of rotation of the bowl immediately before the knife exhaustion in the tissue parts of the tissue parts located in the bowl .
- the spray nozzle is attached to the cutter so that the cryogenic liquefied gas appears briefly in the direction of rotation of the cutter bowl from the knife immersed in the fabric parts onto the fabric parts. As a result, the liquefied gas is immediately mixed into the fabric parts without loss of cooling effect. Since the spray nozzle itself has no contact with the tissue parts, there is no freezing of tissue parts on the nozzle or clogging thereof.
- the spray nozzle is advantageously attached to the cutter in a stationary manner. It is not necessary to e.g. to be designed to be pivotable, since a good distribution of the liquefied gas in the fabric parts is ensured in any case by entry by means of the knives.
- cryogenic liquefied gas introduced into the cutter produces cold exhaust gas that escapes from the fabric parts and inevitably comes into contact with the cutter cover and extracts heat from the cutter cover.
- heat removal from the cutter cover is compensated for by supplying water through an opening made in the cutter cover in the vicinity of the knife. When processing most fabric parts, it is necessary to add water to the fill anyway.
- the device according to the invention has the advantage that, compared to conventional devices of the type mentioned at the outset, a better cooling efficiency is achieved when processing the fabric parts in the cutter.
- the inventive arrangement of the spray nozzle prevents the product from freezing to the spray nozzle, so that there is no undirected introduction of liquefied gas into the knife chamber as in conventional devices. This avoids cooling losses.
- Another advantage of the device according to the invention is that there is no freezing of tissue parts on the cutter cover. This is achieved on the one hand in that the arrangement of the spray nozzle according to the invention immediately mixes the liquefied gas through the knives into the fabric parts, so that the cutter cover does not come into direct contact with cryogenic liquefied gas and therefore does not cool so much that swirled fabric parts on it can freeze. On the other hand, an additional supply of water via at least one opening arranged in the cutter cover near the knives compensates for heat removal from the cutter cover by cold exhaust gas.
- the device according to the invention can be used for processing tissue parts, in particular animal and / or vegetable tissue parts, into 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").
- 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, bird feathers in animal processing plants etc., but also of plastic and rubber parts etc.
- the cutter shown in Figure 1 has a cutter bowl 1, which is rotatable about a vertical axis 2 and by an electric motor, not shown in Arrow direction 5 can be driven.
- a rotatable knife set 3 is arranged vertically to the cutter bowl level 1, 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.
- a spray nozzle 6 is arranged in front of the knife set 3 so that it does not touch the tissue parts 7 located in the bowl.
- the spray nozzle 6 is directed in a direction of rotation 5 immediately before that into the fabric parts.
- the spray nozzle 6 is connected via a line 11 to a storage tank (not shown) for cryogenic liquefied gas.
- the spray nozzle 6 is advantageously attached to the cutter in a stationary manner.
- fresh tissue parts 7, for example meat parts are filled into the cutter bowl 1 up to the fill level 8, the bowl 1 around the axis 2 at 15 to 20 rpm and the knife set 3 around the axis 4 at 2,000 set in rotation at up to 3,000 rpm.
- the tissue parts 7 are transported to the rotating knife set 3, which partly projects into the tissue parts 7. If the knife set 3 is passed several times, the tissue parts 7 are inevitably crushed and mixed.
- cryogenic liquefied gas advantageously liquid nitrogen, is sprayed onto the fabric parts in the direction of rotation 5 of the bowl 1 directly in front of the knife set 3 via the spray nozzle 6.
- the knives of the rotating knife set 3 immersed in the tissue parts immediately mix the liquefied gas into the tissue parts. This ensures good cooling of the entire fabric parts 7 located in the bowl 1. Since the spray nozzle 6 does not come into contact with the tissue parts 7, it cannot become blocked. This also prevents tissue parts from freezing to the spray nozzle, so that there is no undirected delivery of liquefied gas via the nozzle and a loss of cooling associated therewith.
- FIG. 2 shows a plan view of a cutter according to the invention.
- the same components are provided with the same reference numerals as in FIG. 1.
- the knife set 3 is covered with a cover 10 in order to prevent any fabric parts whirled up by the knife set 3 from splashing around.
- This lid 10 is provided with openings 9 in the vicinity of the knife set, which are connected to a line (not shown) for the supply of water.
- 3 water is fed into the cutter bowl through the openings 9 in the lid 10 in the immediate vicinity of the knife set.

Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Verarbeitung von Gebewebteilen, insbesondere tierischer und/oder pflanzlicher Natur, zu Brät, Granulat, etc. durch Zerkleinern und/oder Mischen mittels eines Schneidmischers unter Anwendung 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 zumindest die Messer durch einen Deckel abdeckbar sind, mit einem Vorratstank für tiefkaltes verflüssigtes Gas, einer mit diesem in Verbindung stehenden Zufuhrleitung für verflüssigtes Gas und einer am anderen Ende der Zufuhrleitung angebrachten Sprühdüse.The invention relates to a device for processing tissue parts, in particular animal and / or vegetable nature, into sausage meat, granules, etc. by comminuting and / or mixing by means of a cutting mixer using cryogenic liquefied gas, with a rotating around a substantially vertical rotary shaft Bowl for holding the tissue parts, into which rotating knives seated on a horizontal rotary shaft are immersed, at least the knives being coverable by a lid, with a storage tank for cryogenic liquefied gas, a supply line for liquefied gas connected to this and one at the other end spray nozzle attached to the supply line.
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 Wurtbrät oder Kakaofrüchte zu einer Grundmasse für die Schokoladenherstellung zerkleinert und gemischt. Die zu verarbeitenden Gewebteile, 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 cut into sausage meat or cocoa fruits into a base for chocolate production and mixed. As is known, the tissue parts to be processed, in particular 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.
Die Einbringung mechanischer Energie ist aber 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 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.
In der DE-OS 33 44 521 wird vorgeschlagen, zur Ableitung der vom rotierenden Messer erzeugten Reibungswärme flüssigen Stickstoff mittels einer Sprühdüse direkt auf das Messer zu sprühen. Hierzu wird ein Kutter vorgeschlagen, bei dem in geringem Abstand vom Messer eine Sprühdüse angeordnet und auf das Messer gerichtet ist.In DE-OS 33 44 521 it is proposed to spray liquid nitrogen directly onto the knife by means of a spray nozzle in order to derive the frictional heat generated by the rotating knife. For this purpose, a cutter is proposed in which a spray nozzle is arranged at a short distance from the knife and is directed towards the knife.
Bei der bekannten Vorrichtung ist die Sprühdüse für den flüssigen Stickstoff im Messerraum angeordnet und kommt mit den vom Messer aufgewirbelten Gewebeteilen in Kontakt.In the known device, the spray nozzle for the liquid nitrogen is arranged in the knife chamber and comes into contact with the tissue parts whirled up by the knife.
Bekannte Vorrichtungen der eingangs genannten Art besitzen den Nachteil, daß durch den Kontakt von Gewebeteilen mit der Sprühdüse diese verstopfen kann und Gewebeteile an und in der Umgebung der Sprühdüse festfrieren. Das Festfrieren von Gewebeteilen an der Sprühdüse hat ein ungerichtetes Einführen des tiefkalten verflüssigten Gases in den Messerraum zur Folge, was durch die rotierenden Messer noch verstärkt wird. Dies führt letztlich zu nicht unerheblichen Kühlverlusten.Known devices of the type mentioned have the disadvantage that the contact of tissue parts with the spray nozzle can clog the latter and freeze tissue parts on and in the vicinity of the spray nozzle. The freezing of tissue parts on the spray nozzle results in an undirected introduction of the cryogenic liquefied gas into the knife chamber, which is further reinforced by the rotating knives. Ultimately, this leads to not inconsiderable cooling losses.
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 die Sprühdüse in Drehrichtung der Schüssel vor den in die Gewebeteile eintauchenden Messer über den Gewebeteilen angebracht und auf eine in Drehrichtung der Schüssel unmittelbar vor den in die Gewebeteile entauchenden Messer befindliche Stelle der in der Schüssel befindlichen Gewebeteile gerichtet ist.This object is achieved in that the spray nozzle in the direction of rotation of the bowl in front of the knife immersed in the tissue parts above the tissue parts and is directed to a position in the direction of rotation of the bowl immediately before the knife exhaustion in the tissue parts of the tissue parts located in the bowl .
Die Sprühdüse wird so am Kutter angebracht, daß das tiefkalte verflüssigte Gas in Drehrichtung der Kutterschüssel kurz von den in die Gewebeteile eintauchenden Messer auf die Gewebeteile auftritt. Das verflüssigte Gas wird dadurch sofort in die Gewebeteile eingemischt, ohne Verlust an Kühlwirkung. Da die Sprühdüse selbst keinen Kontakt mit den Gewebeteilen hat, tritt kein Festfrieren von Gewebeteilen an der Düse oder ein Verstopfen derselben auf.The spray nozzle is attached to the cutter so that the cryogenic liquefied gas appears briefly in the direction of rotation of the cutter bowl from the knife immersed in the fabric parts onto the fabric parts. As a result, the liquefied gas is immediately mixed into the fabric parts without loss of cooling effect. Since the spray nozzle itself has no contact with the tissue parts, there is no freezing of tissue parts on the nozzle or clogging thereof.
Vorteilhafterweise ist die Sprühdüse stationär am Kutter angebracht. Es ist nicht nötig, die Sprühdüse z.B. schwenkbar auszubilden, da eine gute Verteilung des verflüssigten Gases in den Gewebeteilen durch Eintrag mittels der Messer ohnehin gewährleistet ist.The spray nozzle is advantageously attached to the cutter in a stationary manner. It is not necessary to e.g. to be designed to be pivotable, since a good distribution of the liquefied gas in the fabric parts is ensured in any case by entry by means of the knives.
In einer bevorzugten Ausführungsform der erfindungsgemäßen Vorrichtung wird vorgeschlagen, im Deckel des Kutters in der Nähe der Messer mindestens eine Öffnung anzubringen, die mit einer Zufuhrleitung für Wasser in Verbindung steht.In a preferred embodiment of the device according to the invention it is proposed to make at least one opening in the cover of the cutter near the knives, which opening is connected to a supply line for water.
Durch das in den Kutter eingebrachte tiefkalte verflüssigte Gas entsteht aus den Gewebeteilen austretendes kaltes Abgas, das zwangsläufig mit dem Kutterdeckel in Kontakt tritt und den Kutterdeckel Wärme entzieht. Um ein Festfrieren von durch das Messer aufgewirbelten Gewebeteilen am kalten Kutterdeckel zu verhindern, wird in der bevorzugten Ausführungsform der Erfindung ein Wärmeentzug aus dem Kutterdeckel durch Zufuhr von Wasser über im Kutterdeckel in der Nähe des Messers angebrachte Öffnung ausgeglichen. Bei der Verarbeitung der meisten Gewebeteile ist eine Zufuhr von Wasser zur Schüttung ohnehin nötig.The cryogenic liquefied gas introduced into the cutter produces cold exhaust gas that escapes from the fabric parts and inevitably comes into contact with the cutter cover and extracts heat from the cutter cover. In order to prevent freezing of tissue parts whirled up by the knife on the cold cutter cover, in the preferred embodiment of the invention heat removal from the cutter cover is compensated for by supplying water through an opening made in the cutter cover in the vicinity of the knife. When processing most fabric parts, it is necessary to add water to the fill anyway.
Die erfindungsgemäße Vorrichtung besitzt den Vorteil, daß im Vergleich zu herkömmlichen Vorrichtungen der eingangs genannten Art ein besserer Kühlwirkungsgrad bei der Verarbeitung der Gewebeteile im Kutter erreicht wird. Durch die erfindungsgemäße Anordnung der Sprühdüse wird nämlich ein Festfrieren von Produkt an der Sprühdüse verhindert, so daß kein ungerichtetes Einführen von verflüssigtem Gas im Messerraum wie bei herkömmlichen Vorrichtungen auftritt. Kühlverluste werden dadurch vermieden.The device according to the invention has the advantage that, compared to conventional devices of the type mentioned at the outset, a better cooling efficiency is achieved when processing the fabric parts in the cutter. The inventive arrangement of the spray nozzle prevents the product from freezing to the spray nozzle, so that there is no undirected introduction of liquefied gas into the knife chamber as in conventional devices. This avoids cooling losses.
Von Vorteil ist bei der erfindungsgemäßen Vorrichtung außerdem, daß kein Festfrieren von Gewebeteilen am Kutterdeckel auftritt. Dies wird einerseits dadurch erreicht, daß durch die erfindungsgemäße Anordnung der Sprühdüse das verflüssigte Gas sofort durch die Messer in die Gewebeteile eingemischt wird, so daß der Kutterdeckel nicht in direktem Kontakt mit tiefkaltem verflüssigtem Gas tritt und daher nicht so stark abkühlt, daß aufgewirbelte Gewebeteile daran festfrieren können. Andererseits wird durch zusätzliche Zufuhr von Wasser über zuminest einer im Kutterdeckel in der Nähe der Messer angeordneten Öffnung ein Wärmeentzug aus dem Kutterdeckel durch kaltes Abgas ausgeglichen.Another advantage of the device according to the invention is that there is no freezing of tissue parts on the cutter cover. This is achieved on the one hand in that the arrangement of the spray nozzle according to the invention immediately mixes the liquefied gas through the knives into the fabric parts, so that the cutter cover does not come into direct contact with cryogenic liquefied gas and therefore does not cool so much that swirled fabric parts on it can freeze. On the other hand, an additional supply of water via at least one opening arranged in the cutter cover near the knives compensates for heat removal from the cutter cover by cold exhaust gas.
Da die Sprühdüse erfindungsgemäß stationär am Kutter angebracht ist, ist keine flexible Leitung für verflüssigtes Gas erforderlich, wie es beispielsweise bei schwenkbaren Düsen der Fall wäre.Since the spray nozzle is attached to the cutter in a stationary manner according to the invention, no flexible conduit for liquefied gas is required, as would be the case, for example, with pivotable nozzles.
Die erfindungsgemäße Vorrichtung kann zur Verarbeitung von Gewebeteilen, insbesondere von tierischen und/oder pflanzlichen Gewebeteilen, 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, Vogelfedern in Tierverwertungsanstalten usw., aber auch von Plastik- und Gummiteilen etc.The device according to the invention can be used for processing tissue parts, in particular animal and / or vegetable tissue parts, into 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, bird feathers in animal processing plants etc., but also of plastic and rubber parts etc.

Here show:
- Figure 1 is a perspective view of a cutter according to the invention with the cutter cover removed;
- Figure 2 is a plan view of a cutter according to the invention with a knife cover.
Der in Figur 1 dargestellte Kutter besitzt eine Kutterschüssel 1, die um eine senkrechte Achse 2 drehbar ist und von einem nichtdargestellten Elektromotor in Pfeilrichtung 5 angetrieben werden kann. Vertikal zur Kutterschüsselebene 1 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 nichtdargestellten Elektromotor angetrieben werden. In Drehrichtung 5 der Kutterschüssel 1 ist vor dem Messersatz 3 eine Sprühdüse 6 so angeordnet, daß sie die in der Schüssel befindlichen Gewebeteile 7 nicht berührt. Die Sprühdüse 6 ist auf eine in Drehrichtung 5 unmittelbar vor dem in die Gewebeteile gerichtete. Die Sprühdüse 6 ist über eine Leitung 11 mit einem nichtdargestellten Vorratstank für tiefkaltes verflüssigtes Gas verbunden.The cutter shown in Figure 1 has a

Beim Betrieb des in Figur 1 dargestellten Kutters werden frische Gewebeteile 7, z.B. Fleischteile, bis zur Füllhöhe 8 in die Kutterschüssel 1 eingefüllt, die Schüssel 1 um die Achse 2 mit 15 bis 20 U/min und der Messersatz 3 um die Achse 4 mit 2.000 bis 3.000 U/min in Rotation versetzt. Durch die rotierende Schüssel 1 werden die Gewebeteile 7 zum rotierenden Messersatz 3 transportiert, der zum Teil in die Gewebeteile 7 hineinragt. Bei mehrmaligem Passieren des Messersatzes 3 werden die Gewebeteile 7 zwangsläufig zerkleinert und durchmischt. Zum Abführen der durch den rotierenden Messersatz 3 verursachten Reibungswärme wird über die Sprühdüse 6 auf die Gewebeteile in Drehrichtung 5 der Schüssel 1 unmittelbar vor dem Messersatz 3 tiefkaltes verflüssigtes Gas, vorteilhafterweise flüssiger Sticksstoff, aufgesprüht.When operating the cutter shown in FIG. 1,
Die in die Gewebeteile eintauchenden Messer des rotierenden Messersatzes 3 mischen das verflüssigte Gas sofort in die Gewebeteile ein. Dadurch ist eine gute Kühlung der gesamten in der Schüssel 1 befindlichen Gewebeteile 7 gewährleistet. Da die Sprühdüse 6 nicht mit den Gewebeteilen 7 in Kontakt kommt, kann diese nicht verstopfen. Auch ein Festfrieren von Gewebeteilen an der Sprühdüse wird dadurch verhindert, so daß keine ungerichtete Abgabe von verflüssigtem Gas über die Düse und ein damit verbundener Kühlverlust auftritt.The knives of the rotating knife set 3 immersed in the tissue parts immediately mix the liquefied gas into the tissue parts. This ensures good cooling of the

Der Messersatz 3 ist mit einem Deckel 10 abgedeckt, um eventuell auftretendes Umherspritzen von durch den Messersatz 3 aufgewirbelten Gewebeteilen zu verhindern. Dieser Deckel 10 ist mit in der Nähe des Messersatzes angebrachten Öffnungen 9 versehen, die mit einer nichtdargestellten Leitung für die Zufuhr von Wasser in Verbindung stehen. Um einen Wärmeentzug aus dem Deckel 10 durch das aus den Gewebeteilen austretende Abgas zu verhindern, wird über die Öffnungen 9 in Deckel 10 in unmittelbarer Nähe des Messersatzes 3 Wasser in die Kutterschüssel zugeführt.Figure 2 shows a plan view of a cutter according to the invention.
