Description

Die Erfindung betrifft eine Vorrichtung zum Schneiden von stückigen verzehrbaren Produkten, insbesondere von auf etwa -9 °C gefrorenen Fleischstücken.The invention relates to a device for cutting lumpy edible products, in particular pieces of meat frozen to about -9 ° C.

Zu den bekannten Zerkleinerungsmaschinen zählen Schüssel- bzw. Bowl-Kutter, Fleischwölfe, Prallmühlen, Feinzerkleinerungsmaschinen sowie Würfelschneider.Known shredding machines include bowl or bowl cutters, meat grinders, impact mills, fine shredding machines and dicing machines.

Bei dem vorstehend genannten Kutter arbeitet in einer sich drehenden, kreisrunden, muldenartigen Schüssel ein Messersatz mit unterschiedlichen, jedoch hohen Drehzahlen. Das in der Mulde befindliche Material wird durch die Schüsseldrehung immer wieder dem Messersatz zugeführt. Nachteilig bei dieser Vorrichtung ist in erster Linie, daß sie nur diskontinuierlich betrieben werden kann.In the above-mentioned cutter, a knife set with different, but high speeds works in a rotating, circular, trough-like bowl. The material in the trough is repeatedly fed into the knife set by rotating the bowl. The main disadvantage of this device is that it can only be operated batchwise.

Demgegenüber arbeiten Fleischwölfe kontiuierlich und werden auf dem Markt für große Tonnagen und auch zur Zerkleinerung von gefrorenem Fleisch angeboten. Das aus Förderschnecke, Schneidmesser und Lochscheibe bestehende Schneidsystem weist eine relativ hohe Reibung auf, so daß der Zerkleinerungsvorgang zu einer höheren Energieeinbringung und somit zu einer Erwärmung des Produktes führt, die eine beginnende Emulgierung, also eine Produktbindung zur Folge hat.In contrast, meat mincers work continuously and are offered on the market for large tonnages and also for shredding frozen meat. That from screw conveyor, The cutting system and perforated disc existing cutting system has a relatively high friction, so that the size reduction process leads to a higher energy input and thus to a heating of the product, which results in the beginning of emulsification, that is, product binding.

Prallmühlen werden insbesondere in der Chemie und Pharmazie aber auch zur Verarbeitung von Kerngut wie z. B. Kakaobohnen eingesetzt. Das zu zerkleinernde Produkt wird mit hoher Geschwindigkeit auf feststehende oder rotierende harte Mahlwerkzeuge geschleudert. Fleischstücke würden in derartigen Prallmühlen eher zerrissen und zerquetscht, nicht aber geschnitten werden.Impact mills are used in particular in chemistry and pharmacy, but also for processing core goods such as. B. cocoa beans. The product to be shredded is hurled at high speed onto fixed or rotating hard grinding tools. Pieces of meat would be torn and crushed in such impact mills, but not cut.

Es sind kontinuierlich arbeitende Feinzerkleinerungsmaschinen bekannt geworden (siehe z. B. DE-PS 28 23 245), die mit einem berührungsfrei arbeitenden, hochtourig umlaufenden Rotor-Stator-System versehen sind. Diese hochtourig umlaufenden Schneidsysteme sind sowohl für das Schneiden als auch für das Emulgieren konzipiert. Der bei dem Einsatz dieser Maschinen üblicherweise gewünschte Emulgieranteil an dem erstellten Produkt läßt sich nicht vermeiden. Diese Feinzerkleinerungsmaschinen werden insbesondere für Produkte mit einer Partikelgröße unterhalb 2 mm eingesetzt.Continuous fine grinding machines have become known (see, for example, DE-PS 28 23 245), which are provided with a non-contact, high-speed rotating rotor-stator system. These high-speed all-round cutting systems are designed for both cutting and emulsifying. The amount of emulsification in the product that is usually required when using these machines cannot be avoided. These fine grinding machines are used in particular for products with a particle size below 2 mm.

Mit Würfelschneidern lassen sich nur Produktstücke mit einer Kantenlänge ≧ 10 mm herstellen; sie sind auch konzeptionell nicht für Fleischzerkleinerungsprozesse geeignet.Only product pieces with an edge length of ≧ 10 mm can be produced with cube cutters; They are also not conceptually suitable for meat cutting processes.

Allen vorbekannten Maschinen gemeinsam ist hinsichtlich der kontinuierlichen Fleischschneideprozesse ein ungünstiges Preis-/Leistungsverhältnis.Common to all previously known machines is an unfavorable price / performance ratio with regard to the continuous meat cutting processes.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu entwickeln, mit der sich in einem kontinuierlichen Durchlauf insbesondere gefrorene Fleischstücke weiter zerkleinern lassen.The invention has for its object to develop a device with which in particular frozen pieces of meat can be minced further in a continuous pass.

Diese Aufgabe wird erfindungsgemäß durch folgende Merkmale gelöst:

  • a) in einem Schneidgehäuse rotieren Messersätze, die mit lichtem axialen Abstand voneinander drehfest aber leicht austauschbar auf dem horizontalen oder gegenüber der Horizontalen geneigten Wellenstumpf eines Drehstrom-Motors befestigt sind,
  • b) jeder Messersatz weist eine axiale Förderkomponente auf;
  • c) die Messersätze rotieren mit Drehzahlen zwischen 500 und 3000 U/min;
  • d) die Messersätze sind in ihrer Konfiguration sowie in ihrem axialen Abstand voneinander so ausgebildet, daß gefrorene Fleischstücke mit einer Kantenlänge von 250 x 250 x 250 mm unter geringstmöglicher Wärmeaufnahme mit einem geringstmöglichen Emulgieranteil auf eine Körnung von 2 bis 8 mm geschnitten werden (Fleischkörnung);
  • e) das Schneidgehäuse weist in seinem tiefsten Bereich eine nach unten offene Austragöffnung für einen kontinuierlichen Fleischkörnung-Austrag unter Schwerkrafteinwirkung auf;
  • f) dem Schneidgehäuse ist in axialer Richtung gesehen eine kontinuierlich arbeitende Zufuhreinrichtung für die Fleischstücke vorgeschaltet, die den Fleischstücken eine gegen die Umlaufebene des ersten Messersatzes gerichtete Förderkomponente verleiht.
This object is achieved according to the invention by the following features:
  • a) rotating knife sets in a cutting housing, which are fixed with a clear axial distance from one another in a rotationally fixed but easily replaceable manner on the horizontal or inclined stub shaft of a three-phase motor,
  • b) each knife set has an axial conveying component;
  • c) the knife sets rotate at speeds between 500 and 3000 rpm;
  • d) The knife sets are configured in their configuration and in their axial spacing from one another in such a way that frozen pieces of meat with an edge length of 250 x 250 x 250 mm are cut to a grain size of 2 to 8 mm with the lowest possible heat absorption with the lowest possible amount of emulsifying agent (meat grain) ;
  • e) the cutting housing has in its deepest area a discharge opening which is open at the bottom for a continuous meat grain discharge under the action of gravity;
  • f) seen in the axial direction, the cutting housing is preceded by a continuously operating feed device for the pieces of meat, which gives the pieces of meat a conveying component directed against the plane of rotation of the first set of knives.

Soweit in den Patentansprüchen Bezug genommen wird auf Fleisch, so handelt es sich hierbei nur um eine beispielsweise Produktangabe, die auch Innereien umfaßt. Andere Produktarten wie z. B. Kerngut, Obst, Gemüse oder dergleichen sind denkbar. Unter "verzehrbaren Produkten" soll auch Tierfutter, wie z. B. petfood, verstanden werden.As far as the patent claims refer to meat, this is only an example of a product specification, which also includes offal. Other types of products such as B. core material, fruit, vegetables or the like are conceivable. Under "edible products" animal feed, such as. B. petfood can be understood.

Ein wesentliches Erfindungsmerkmal liegt in der kontinuierlichen Arbeitsweise. Die erfindungsgemäße Schneidmaschine läßt sich somit in vorhandene, kontinuierlich arbeitende Linien einfach integrieren. Erfindungswesentlich ist ferner die Körnung der zugeführten gefrorenen Fleischstücke auf eine verhältnismäßig kleine Korngröße, wobei dieser Schnittvorgang unter möglichst geringer Energieeinbringung durchgeführt wird, damit das Endprodukt körnig bis rieselfähig ist und eine nahezu definierte Korngröße aufweist. Abweichend von den bekannten Verfahren und Vorrichtungen wird also ein Produkt mit einem geringstmöglichen Emulgieranteil hergestellt.An essential feature of the invention is the continuous way of working. The cutting machine according to the invention can thus be easily integrated into existing, continuously operating lines. Essential to the invention is also the granulation of the supplied frozen meat pieces to a relatively small grain size, this cutting process being carried out with as little energy input as possible so that the end product is granular to free-flowing and has an almost defined grain size. In a departure from the known methods and devices, a product with the lowest possible emulsifying content is therefore produced.

Die das Ausgangsprodukt bildenden Fleischstücke weisen meist eine kleinere Kantenlänge auf als die vorstehend zitierte Maximalangabe; es kann auch ein sogenannter Staubanteil vorliegen. Das Ausgangsprodukt kann auch Temperaturen bis in die Nähe des Gefrierpunktes aufweisen, so daß das Material als angetaut bezeichnet werden kann.The pieces of meat forming the starting product usually have a shorter edge length than the maximum specification cited above; there may also be a so-called dust component. The starting product can also have temperatures close to freezing, so that the material can be described as thawed.

Zur Veränderung des Produktdurchsatzes und/oder der Feinheit der Produktkörnung können die Schneidwerkzeuge erfindungsgemäß hinsichtlich Drehzahl, Durchmesser, Geometrie, Anzahl und/oder axialem Abstand voneinander modifiziert werden. Hierdurch läßt sich auch die Exaktheit des Schnittes bzw. des Schneidvorganges beeinflussen. Deshalb ist es vorteilhaft, wenn sich die Schneidwerkzeuge leicht auswechseln lassen.To change the product throughput and / or the fineness of the product granulation, the cutting tools can be modified according to the invention in terms of speed, diameter, geometry, number and / or axial distance from one another. This can also influence the exactness of the cut or the cutting process. It is therefore advantageous if the cutting tools can be easily replaced.

Die Zufuhr der Produktstücke in den Bereich der rotierenden Messersätze erfolgt kontinuierlich über eine Förderschnecke, ein Förderband oder aber einen Schwerkraftförderer. Dabei läßt sich durch Verstellung der Förderleistung ebenfalls die Feinheit des Endproduktes beeinflussen.The product pieces are continuously fed into the area of the rotating knife sets via a screw conveyor, a conveyor belt or a gravity conveyor. The fineness of the end product can also be influenced by adjusting the delivery rate.

Als Antrieb für die Förderschnecke bzw. das Förderband kann ebenfalls ein Drehstrom-Motor vorgesehen werden, der ebenso wie der Drehstrom-Motor für die Messersätze mit einem vorgeschalteten Umrichter zur Drehzahl-Regelung bestückt sein kann. Unter Berücksichtigung der Pohlzahlen lassen sich jedoch zwei oder drei verschiedene Drehzahlen auch ohne Umrichter realisieren.A three-phase motor can also be provided as the drive for the screw conveyor or the conveyor belt and, like the three-phase motor for the knife sets, can be equipped with an upstream converter for speed control. However, taking into account the Pohl numbers Realize two or three different speeds even without a converter.

Bei Verwendung einer Förderschnecke lassen sich Produktdurchsatz und -qualität, also Feinheit und Körnigkeit des erzeugten Endproduktes, durch Veränderung der Drehzahl, des Schneckendurchmessers und/oder der Schneckensteigung beeinflussen.When using a screw conveyor, product throughput and quality, i.e. fineness and granularity of the end product produced, can be influenced by changing the speed, the screw diameter and / or the screw pitch.

Die erfindungsgemäße Vorrichtung läßt sich aufgrund ihrer einfachen Konzeption sehr schnell durch Messertausch und Drehzahländerung an die Endprodukt-Wünsche des Kunden anpassen. Die Maschine ist einfach im Aufbau und daher nur wenig anfällig. Sie entspricht den Hygieneanforderungen in der Nahrungsmittelverarbeitung, läßt sich in vorhandene Linien gut integrieren, ist kompakt in ihren Abmessungen und kann auch parallel oder - wenn sehr hohe Zerkleinerungsgrade gefordert sind - in Tandem angeordnet werden. Die Konzeption ist besonders für hohe Durchsatzleistungen von z. B. 40.000 kg pro Stunde geeignet, läßt aber auch sehr viel geringere Leistungen von z. B. nur 1000 kg/h zu. Das Preis-/Leistungsverhältnis zu den auf dem Markt befindlichen Maschinen ist konzeptionell bedingt sehr günstig.Due to its simple design, the device according to the invention can be adapted very quickly to the end product requirements of the customer by changing the knife and changing the speed. The machine is simple in construction and therefore only slightly susceptible. It meets the hygiene requirements in food processing, can be easily integrated into existing lines, is compact in size and can also be arranged in parallel or - if very high levels of comminution are required - in tandem. The conception is especially for high throughputs of e.g. B. 40,000 kg per hour, but can also be much lower performance of z. B. only 1000 kg / h. The price / performance ratio of the machines on the market is conceptually very favorable.

Im Boden des Schneidgehäuses 4 ist unmittelbar vor dem Motorschild 5 eine nach unten offene Austragöffnung 6 vorgesehen.The cutting machine shown in FIGS. 1 to 4 comprises a three-phase motor 1 with a horizontally oriented stub shaft 2, on which knives 3. In the bottom of the cutting housing 4, a downwardly open discharge opening 6 is provided directly in front of the motor shield 5.

Dem Schneidgehäuse 4 ist ein Schneckengehäuse 7 vorgeschaltet, in dem eine Förderschnecke 8 umläuft, die mit dem den Messersatz tragenden Wellenstumpf 2 fluchtet und als Antrieb ebenfalls einen Drehstrom-Motor 9 aufweist. Das Schneckengehäuse 7 fluchtet mit seiner Unterkante mit der Unterkante des Schneidgehäuses 4 und weist in seiner vorderen Oberseite einen Einlauftrichter 10 für das zu zerschneidende Produkt auf. Dessen dem Schneidgehäuse 4 zugewandte Wandung bildet mit der oberen Wandung des Förderschneckengehäuses 7 eine Schneidkante 10a für eine grobe Vorzerkleinerung großer Fleischstücke.The cutting housing 4 is preceded by a worm housing 7, in which a screw conveyor 8 rotates, which is aligned with the stub shaft 2 carrying the knife set and also has a three-phase motor 9 as a drive. The lower edge of the worm housing 7 is aligned with the lower edge of the cutting housing 4 and has an inlet funnel 10 in its front upper side for the product to be cut. Whose wall facing the cutting housing 4 forms with the upper wall of the screw conveyor housing 7 a cutting edge 10a for a rough pre-comminution of large pieces of meat.

Insbesondere Figur 1 läßt erkennen, daß bei diesem Ausführungsbeispiel der Durchmesser der Förderschnecke 8 etwa dem Durchmesser der Messer 3,3a entspricht.In particular, Figure 1 shows that in this embodiment, the diameter of the screw conveyor 8 corresponds approximately to the diameter of the knives 3,3a.

Jeder der beiden Drehstrom-Motoren 1, 9 kann mit einem vorgeschalteten Umrichter zur Drehzahl-Regelung bestückt sein.Each of the two three-phase motors 1, 9 can be equipped with an upstream converter for speed control.

Das zu zerkleinernde stückige Produkt, z. B. gefrorene Fleischstücke mit einer Kantenlänge von maximal 250 x 250 x 250 mm, wird in einem kontinuierlichen Produktstrom in den Einlauftrichter 10 und dadurch in den Förderbereich der Förderschnecke 8 geleitet. Übergroße Produktstücke werden von der Förderschnecke 8 vorzerkleinert. Im übrigen werden die Produktstücke in Form eines Produktstranges unmittelbar den rotierenden Messern 3,3a zugeführt, die mit jeweils axialem lichtem Abstand voneinander auf dem Wellenstumpf 2 sitzen, den Ausfallquerschnitt der Austragöffnung 6 jedoch weitgehend freihalten. Im Bereich der Austragöffnung 6 ist nur ein einziges Messer 3a vorgesehen. Die Förderschnecke 8 läuft mit 20 bis 200 U/min um, während die Messer 3,3a in entgegengesetzter Richtung mit Drehzahlen zwischen 500 und 3000 U/min rotieren. Die von der Förderschnecke 8 den Messern 3,3a zugeführten Produktstücke werden im Schneidgehäuse 4 unter geringsmöglicher Emulgierung klumpenfrei auf eine Körnung von 2 bis 8 mm geschnitten.The lumpy product to be shredded, e.g. B. frozen pieces of meat with an edge length of maximum 250 x 250 x 250 mm, is passed in a continuous product stream into the inlet funnel 10 and thereby into the conveying area of the screw conveyor 8. Oversized product pieces are pre-shredded by the screw conveyor 8. Otherwise, the product pieces in the form of a product strand are fed directly to the rotating knives 3, 3a, each with an axial sit a short distance from each other on the stub shaft 2, but keep the discharge cross-section of the discharge opening 6 largely free. Only a single knife 3a is provided in the region of the discharge opening 6. The screw conveyor 8 rotates at 20 to 200 rpm, while the knives 3, 3a rotate in the opposite direction at speeds between 500 and 3000 rpm. The product pieces fed by the screw conveyor 8 to the knives 3, 3a are cut in the cutting housing 4 with the least possible emulsification to a lump size of 2 to 8 mm.

Die in Figur 5 dargestellte Ausführungsform unterscheidet sich von der der Figur 1 lediglich dadurch, daß der Schnekkengehäuse-Durchmesser d nur etwa dem halben Schneidgehäuse-Durchmesser D entspricht. Der Durchmesser der Förderschnecke 8 entspricht somit etwa dem Radius der Messersätze 3,3a.The embodiment shown in FIG. 5 differs from that of FIG. 1 only in that the screw housing diameter d corresponds only to approximately half the cutting housing diameter D. The diameter of the screw conveyor 8 thus corresponds approximately to the radius of the knife sets 3, 3a.

Die in den Figuren 6 bis 9 dargestellte abgewandelte Ausführungsform unterscheidet sich von der der Figuren 1 bis 4 im wesentlichen in zwei Merkmalen:The modified embodiment shown in FIGS. 6 to 9 essentially differs from that of FIGS. 1 to 4 in two features:

Der Drehstrom-Motor 1 ist mit seinem Wellenstumpf 2 gegenüber der Horizontalen um etwa 45° geneigt angeordnet; und anstelle einer Förderschnecke erfolgt die Zufuhr der zu zerkleinernden Produktstücke unter Ausnutzung ihrer Schwerkraft über einen Einlauftrichter 11 unmittelbar in den Arbeitsbereich der Messersätze 3.The three-phase motor 1 is arranged with its stub shaft 2 inclined by approximately 45 ° with respect to the horizontal; and instead of a screw conveyor, the product pieces to be shredded are fed directly into the working area of the knife sets 3 via an inlet funnel 11 using their gravity.

Figur 10 läßt erkennen, daß die Messer 3 als Doppelmesser ausgebildet sind, deren beiden Flügel an ihrer vorlaufenden Schneide 14 mit einem Schrägschliff 15 mit einem Schliffwinkel α von etwa 25° - 30° versehen sind (siehe auch Figur 11). Dieser Anschliffwinkel α wird entsprechend dem zu schneidenden Produkt gewählt. Stumpfe Messer werden unter diesem Winkel α nachgeschliffen. Figur 11 läßt erkennen, daß der eigentliche Schrägschliff 15 nur verhältnismäßig kurz ausgebildet ist und dann in eine ballige Förderfläche 16 übergeht, die einen Radius R aufweist und sich über die Breite x erstreckt. Diese Förderfläche 16 verleiht dem Produkt die vorstehend bereits erwähnte Förderkomponente 13. Die Länge des Schrägschliffs 15 kann etwa 2 mm betragen; die Breite x liegt im Bereich von 25 - 40 mm; die Dicke S eines Messers 3 kann zwischen 6 und 10 mm liegen.FIG. 10 shows that the knives 3 are designed as double knives, the two blades of which are provided on their leading cutting edge 14 with a bevel 15 with a grinding angle α of approximately 25 ° -30 ° (see also FIG. 11). This grinding angle α is chosen according to the product to be cut. Blunt knives are reground α at this angle. Figure 11 shows that the actual bevel 15 is only relatively short and then merges into a spherical conveying surface 16 which has a radius R and extends across the width x. This conveying surface 16 gives the product the conveying component 13 already mentioned above. The length of the bevel 15 can be approximately 2 mm; the width x is in the range of 25-40 mm; the thickness S of a knife 3 can be between 6 and 10 mm.

Ein Messersatz besteht vorzugsweise aus 3 bis 5 Doppelmessern, die - wie es Figur 12 erkennen läßt - gegeneinander umfangsversetzt angeordnet sind.A set of knives preferably consists of 3 to 5 double knives which, as can be seen in FIG. 12, are arranged circumferentially offset from one another.

Bei der in Figur 13 dargestellten abgewandelten Ausführungsform verjüngt sich der erste Abschnitt 4a des Schneidgehäuses 4 in Förderrichtung 12 gesehen im Durchmesser etwas, um so eine Stauwirkung hervorzurufen. Bei diesem Lösungsvorschlag weist das erste Messer des Messersatzes somit einen größeren Durchmesser auf als die folgenden Messer, um einen gleichbleibend großen radialen Abstand a zum Schneidgehäuse 4 aufrechtzuerhalten.In the modified embodiment shown in FIG. 13, the first section 4a of the cutting housing 4 tapers somewhat in diameter, as seen in the conveying direction 12, so as to produce a backlog effect. In this proposed solution, the first knife of the knife set thus has a larger diameter than the following knives in order to maintain a constant large radial distance a from the cutting housing 4.
