Definitions
- the invention relates to a transverse cutting blade for a device for processing food to produce plucked or pulled food products, with a blade body which has a large number of projecting elements on a planar surface. Furthermore, the invention relates to a device for processing food, with a feed chute for the food.
- a generic transverse cutting knife is in DE 10 2019 130 221 B3 described. Such transverse cutting knives are used to produce plucked or pulled food products, such as pulled pork, ie plucked pork.
- the problem with the known device and the transverse cutting blade used therein is that the transverse cutting blade becomes clogged with the plucked product during operation, which requires frequent cleaning of the transverse cutting blade and can lead to machine downtimes.
- the spokes running outwards from a central area of the transverse cutting blade result in a blade body which, at least in the region that moves over an opening in a cutting gate when the transverse cutting blade is in use, has a large number of recesses through which the cut outs from the foodstuffs during use of the transverse cutting blade plucked fibers can pass through, so that clogging of the cross cutting blade is prevented during operation.
- the transverse cutting knife according to the invention can be used over a significantly longer period of time than is the case with the previously known designs.
- a further advantage of the transverse cutting blade according to the invention is its reduced mass, which has an advantageous effect on the drive components involved, such as shafts, bearings and motors.
- the spokes are connected to one another by means of at least one cross brace.
- the strength of the blade body is significantly increased and a sufficiently large area remains for the recesses.
- a proportion of the area occupied by all the recesses of the entire area of the blade body moving over an opening of the cutting frame when the transverse cutting blade is in use is 30-90%, preferably 60-85%, particularly preferably 70-80%.
- Such a proportion of the recesses over the entire surface has proven to be particularly suitable with regard to good passage or passage of the plucked product through the blade body on the one hand and sufficient strength of the blade body on the other.
- a simplified manufacture of the transverse cutting blade according to the invention results if the recesses are formed from a closed blade body by means of laser beam cutting.
- the protruding elements are arranged at least on some of the spokes running outwards from the central area of the transverse cutting blade. This results in a very uniform distribution over the surface of the knife body of the elements that act on the food and protrude from the planar surface.
- a further advantageous embodiment can consist in the protruding elements being arranged on the at least one cross brace connecting the spokes to one another. This improves the effect of the above elements in creating plucked or pulled food products.
- the recesses in the blade body which account for 30 - 90% of the total area of the blade body moving over the opening of the cutting gate when the transverse cutting blade is in use, ensure that the plucked food product can pass through the recesses and thus not through the blade body upset.
- the transverse cutting knife according to the invention can be used over a significantly longer period of time than is the case with the previous versions.
- This embodiment of the transverse cutting blade also has the advantage of a reduced mass, which has an advantageous effect on the drive components involved.
- a particularly advantageous development of this embodiment can consist in the fact that the proportion of the area occupied by all the recesses of the entire area of the blade body moving over the opening of the cutting frame when the transverse cutting blade is in use is 60-85%, preferably 70-80%. Such a proportion of the recesses on the surface of the transverse cutting blade has proven to be particularly advantageous with regard to reduced contamination of the same.
- This embodiment can also result in a simplified manufacture of the transverse cutting blade if the recesses are formed from a closed blade body by means of laser beam cutting.
- Claim 10 specifies a device for processing foodstuffs with a transverse cutting blade according to the invention.
- This device can be used particularly advantageously for producing plucked or pulled food products, with all of the above-mentioned advantages of the transverse cutting blade taking effect.
- the Figures 1 to 4 show a transverse cutting blade 1 for a device, not shown in its entirety, for processing foodstuffs, also not shown, in order to produce plucked or pulled food products, such as pulled pork, i.e. plucked pork, from a starting product.
- a so-called cutting gate 2 is shown, which is shown in 4 "x" designated feed direction of the food is arranged in front of the cross cutting knife 1.
- the cutting gate 2 has an opening 2a from which the food emerges in a pre-cut state and is conveyed to the cross-cutting blade 1 .
- the transverse cutting blade 1 has a blade body 3 which has a plurality of projecting elements 4 on a planar surface 3a thereof.
- the protruding elements 4 are used in a manner known per se to pluck or pull individual fibers out of the food.
- the blade body 3 itself has no cutting properties; Rather, the plucking or pulling achieved by the protruding elements 4 is the essential property of the transverse cutting blade 1 or of the blade body 3 of the same.
- the blade body 3 consists of a plurality of spokes 6 running outwards from a central region 5 of the transverse cutting blade 1 and a plurality of spokes 6 together connecting cross braces 7 formed.
- the spokes 6 accordingly run in the radial direction of the blade body 3 of the transverse cutting blade 1
- the transverse struts 7 run in the circumferential direction of the blade body 3 .
- the cross braces 7 could also be dispensed with, which would further reduce the mass of the blade body 3 .
- the cross braces 7 provide higher strength of the knife body 3.
- spokes 6 preferably six or more spokes 6, more preferably eight or more spokes 6 should be provided.
- twelve spokes 6 are provided, and the number of spokes 6 also depends in particular on the diameter of the transverse cutting blade 1 . A larger number of spokes 6 reduces the risk of larger pieces of food passing between them and possibly not being processed as desired.
- a portion of the surface occupied by all the recesses 8 formed between the spokes 6 and the cross braces 7 of the entire surface of the blade body 3 moving over the opening 2a of the cutting frame 2 when the transverse cutting blade 1 is in use is 30 to 90%, preferably 60% to 85% and more preferably 70 to 80%.
- the area of the knife body 3 moving over the cutting gate 2 or over the opening 2a of the cutting gate 2 can be seen.
- the recesses 8 can, as in 3 recognizable, extend in the radial direction on both sides over the area of the blade body 3 moving over the cutting gate 2 or over the opening 2a of the cutting gate 2. However, this is not absolutely necessary.
- the area of the blade body 3 moving over the opening 2a of the cutting frame 2 is therefore the effective area of the Cross cutting knife 1.
- the central area 5 of the knife body 3 is, however, completely closed in the present case, since only a very small amount of impact by the food is to be expected in this area. Furthermore, by dispensing with the recesses 8 in the central area 5, the rigidity and strength of the transverse cutting blade 1 is increased.
- the protruding elements 4 are arranged at least on some of the spokes 6 extending outwards from the central area 5 of the transverse cutting blade 1 and/or on the transverse struts 7 .
- the protruding elements 4 are arranged on all spokes 6 and only on the outermost cross brace 7 connecting the spokes 6 to one another. Due to the fact that none of the protruding elements 4 are located on the further transverse struts 7, these can be designed with a smaller width, which contributes to increasing the surface area of the recesses 8.
- other arrangements of the protruding elements 4 on the blade body 3 are also conceivable.
- the transverse cutting blade 1 is preferably made of a suitable metal. In order to increase the area taken up by the recesses 8, higher-strength materials can also be used.
- the recesses 8 can be formed from a closed blade body 3, for example a flat, round circular disk, by means of laser beam cutting.
- the spokes 6 and, if present, the transverse struts 7 are produced by producing the recesses 8 by means of laser beam cutting.
- other ways of producing the recesses 8 or the spokes 6 and the transverse struts 7 are also conceivable.
- the recesses 8 are indeed provided in the Figures 1 to 4
- the spokes 6 that are present and the cross braces 7 that connect them are not present.
- the recesses 8 can have any desired shape, ie they can be round, triangular or polygonal, slot-shaped or designed in any other way. It is not necessary for the recesses 8 to have the same shape and/or have size.
- the distribution of the recesses 8 over the flat surface 3a of the blade body 3 is in principle arbitrary.
- a proportion of the area occupied by all the recesses 8 of the entire area of the blade body 3 moving over the opening 2a of the cutting frame 2 when the transverse cutting blade 1 is in use is 30 to 90%, preferably 60 to 85% and particularly preferably 70 to 80% %.
- the recesses 8 of this embodiment can also be formed by means of laser beam cutting from a closed blade body 3, for example a flat, round circular disk.

Description
Die Erfindung betrifft ein Querschneidemesser für eine Vorrichtung zum Bearbeiten von Lebensmitteln zum Erzeugen von gezupften oder gepullten Lebensmittelprodukten, mit einem Messerkörper, der auf einer Planfläche eine Vielzahl von vorstehenden Elementen aufweist. Des Weiteren betrifft die Erfindung eine Vorrichtung zum Bearbeiten von Lebensmitteln, mit einem Zuführschacht für die Lebensmittel.The invention relates to a transverse cutting blade for a device for processing food to produce plucked or pulled food products, with a blade body which has a large number of projecting elements on a planar surface. Furthermore, the invention relates to a device for processing food, with a feed chute for the food.
Ein gattungsgemäßes Querschneidemesser ist in der
Es ist daher Aufgabe der vorliegenden Erfindung, ein Querschneidemesser für eine Vorrichtung zum Verarbeiten von Lebensmitteln sowie eine derartige Vorrichtung zu schaffen, die einen geringeren Reinigungsaufwand erfordern.It is therefore the object of the present invention to create a transverse cutting blade for a device for processing foodstuffs and a device of this type which require less cleaning effort.
Erfindungsgemäß wird diese Aufgabe durch die in Anspruch 1 genannten Merkmale gelöst.According to the invention, this object is achieved by the features mentioned in
Durch die von einem zentralen Bereich des Querschneidemessers nach außen verlaufenden Speichen ergibt sich ein Messerkörper, der zumindest in dem sich im Einsatz des Querschneidemessers über eine Öffnung eines Schneidgatters bewegenden Bereich eine Vielzahl von Ausnehmungen aufweist, durch welche während des Einsatzes des Querschneidemessers die aus dem Lebensmittel gezupften Fasern hindurchgehen können, so dass ein Zusetzen des Querschneidemessers während des Betriebs verhindert wird. Dadurch kann das erfindungsgemäße Querschneidemesser über einen deutlich längeren Zeitraum eingesetzt werden als dies bei den bisherig bekannten Ausführungen der Fall ist.The spokes running outwards from a central area of the transverse cutting blade result in a blade body which, at least in the region that moves over an opening in a cutting gate when the transverse cutting blade is in use, has a large number of recesses through which the cut outs from the foodstuffs during use of the transverse cutting blade plucked fibers can pass through, so that clogging of the cross cutting blade is prevented during operation. As a result, the transverse cutting knife according to the invention can be used over a significantly longer period of time than is the case with the previously known designs.
Ein weiterer Vorteil des erfindungsgemäßen Querschneidemessers ist dessen reduzierte Masse, die sich vorteilhaft auf die beteiligten Antriebskomponenten, wie Wellen, Lager und Motoren, auswirkt.A further advantage of the transverse cutting blade according to the invention is its reduced mass, which has an advantageous effect on the drive components involved, such as shafts, bearings and motors.
In einer sehr vorteilhaften Weiterbildung der Erfindung kann vorgesehen sein, dass die Speichen mittels wenigstens einer Querstrebe miteinander verbunden sind. Dadurch wird die Festigkeit des Messerkörpers deutlich erhöht und es verbleibt dennoch eine ausreichend große Fläche für die Ausnehmungen.In a very advantageous development of the invention, it can be provided that the spokes are connected to one another by means of at least one cross brace. As a result, the strength of the blade body is significantly increased and a sufficiently large area remains for the recesses.
In einer weiteren vorteilhaften Weiterbildung der Erfindung kann vorgesehen sein, dass ein Anteil der von sämtlichen Ausnehmungen eingenommenen Fläche an der gesamten, sich im Einsatz des Querschneidemessers über eine Öffnung des Schneidgatters bewegenden Fläche des Messerkörpers 30 - 90 %, vorzugsweise 60 - 85 %, besonders bevorzugt 70 - 80 %, beträgt. Ein derartiger Anteil der Ausnehmungen an der gesamten Fläche hat sich im Hinblick auf ein gutes Durchlassen bzw. Durchlaufen des gezupften Produkts durch den Messerkörper einerseits und einer ausreichenden Festigkeit des Messerkörpers andererseits als besonders geeignet erwiesen.In a further advantageous development of the invention, it can be provided that a proportion of the area occupied by all the recesses of the entire area of the blade body moving over an opening of the cutting frame when the transverse cutting blade is in use is 30-90%, preferably 60-85%, particularly preferably 70-80%. Such a proportion of the recesses over the entire surface has proven to be particularly suitable with regard to good passage or passage of the plucked product through the blade body on the one hand and sufficient strength of the blade body on the other.
Eine vereinfachte Fertigung des erfindungsgemäßen Querschneidemessers ergibt sich, wenn die Ausnehmungen mittels Laserstrahlschneiden aus einem geschlossenen Messerkörper gebildet sind.A simplified manufacture of the transverse cutting blade according to the invention results if the recesses are formed from a closed blade body by means of laser beam cutting.
In einer weiteren sehr vorteilhaften Ausgestaltung der Erfindung kann vorgesehen sein, dass die vorstehenden Elemente zumindest auf einigen der von dem zentralen Bereich des Querschneidemessers nach außen verlaufenden Speichen angeordnet sind. Dadurch ist eine sehr gleichmäßige Verteilung der auf das Lebensmittel einwirkenden, von der Planfläche vorstehenden Elemente über die Fläche des Messerkörpers gegeben.In a further very advantageous embodiment of the invention, it can be provided that the protruding elements are arranged at least on some of the spokes running outwards from the central area of the transverse cutting blade. This results in a very uniform distribution over the surface of the knife body of the elements that act on the food and protrude from the planar surface.
Eine weitere vorteilhafte Ausgestaltung kann darin bestehen, dass die vorstehenden Elemente auf der wenigstens einen die Speichen miteinander verbindenden Querstrebe angeordnet sind. Dies verbessert die Wirkung der vorstehenden Elemente bezüglich des Erzeugens von gezupften oder gepullten Lebensmittelprodukten.A further advantageous embodiment can consist in the protruding elements being arranged on the at least one cross brace connecting the spokes to one another. This improves the effect of the above elements in creating plucked or pulled food products.
Eine alternative Lösung der Aufgabe ist in Anspruch 7 angegeben.An alternative solution to the problem is specified in
Durch die Ausnehmungen in dem Messerkörper, deren Anteil an der gesamten, sich im Einsatz des Querschneidemessers über die Öffnung des Schneidgatters bewegenden Fläche des Messerkörpers 30 - 90 % beträgt, wird gewährleistet, dass das gezupfte Lebensmittelprodukt durch die Ausnehmungen hindurchgelangen kann und damit den Messerkörper nicht zusetzt. Dadurch kann das erfindungsgemäße Querschneidemesser über einen deutlich längeren Zeitraum eingesetzt werden als dies bei den bisherigen Ausführungen der Fall ist.The recesses in the blade body, which account for 30 - 90% of the total area of the blade body moving over the opening of the cutting gate when the transverse cutting blade is in use, ensure that the plucked food product can pass through the recesses and thus not through the blade body upset. As a result, the transverse cutting knife according to the invention can be used over a significantly longer period of time than is the case with the previous versions.
Auch diese Ausführungsform des Querschneidemessers hat den Vorteil einer reduzierten Masse, die sich vorteilhaft auf die beteiligten Antriebskomponenten auswirkt.This embodiment of the transverse cutting blade also has the advantage of a reduced mass, which has an advantageous effect on the drive components involved.
Eine besonders vorteilhafte Weiterbildung dieser Ausführungsform kann darin bestehen, dass der Anteil der von sämtlichen Ausnehmungen eingenommenen Fläche an der gesamten, sich im Einsatz des Querschneidemessers über die Öffnung des Schneidgatters bewegenden Fläche des Messerkörpers 60 - 85 %, vorzugsweise 70 - 80 %, beträgt. Ein derartiger Anteil der Ausnehmungen an der Fläche des Querschneidemessers hat sich als besonders vorteilhaft im Hinblick auf eine verringerte Verschmutzung desselben erwiesen.A particularly advantageous development of this embodiment can consist in the fact that the proportion of the area occupied by all the recesses of the entire area of the blade body moving over the opening of the cutting frame when the transverse cutting blade is in use is 60-85%, preferably 70-80%. Such a proportion of the recesses on the surface of the transverse cutting blade has proven to be particularly advantageous with regard to reduced contamination of the same.
Auch bei dieser Ausführungsform kann sich eine vereinfachte Fertigung des Querschneidemessers ergeben, wenn die Ausnehmungen mittels Laserstrahlschneiden aus einem geschlossenen Messerkörper gebildet sind.This embodiment can also result in a simplified manufacture of the transverse cutting blade if the recesses are formed from a closed blade body by means of laser beam cutting.
In Anspruch 10 ist eine Vorrichtung zum Bearbeiten von Lebensmitteln mit einem erfindungsgemäßen Querschneidemesser angegeben.Claim 10 specifies a device for processing foodstuffs with a transverse cutting blade according to the invention.
Diese Vorrichtung lässt sich besonders vorteilhaft zum Erzeugen von gezupften oder gepullten Lebensmittelprodukten einsetzen, wobei sämtliche der oben genannten Vorteile des Querschneidemessers zum Tragen kommen.This device can be used particularly advantageously for producing plucked or pulled food products, with all of the above-mentioned advantages of the transverse cutting blade taking effect.

Die
Das Querschneidemesser 1 weist einen Messerkörper 3 auf, der auf einer Planfläche 3a desselben eine Vielzahl von vorstehenden Elementen 4 aufweist. Die vorstehenden Elemente 4 dienen in an sich bekannter Weise dazu, einzelne Fasern aus dem Lebensmittel zu zupfen bzw. zu pullen. Der Messerkörper 3 selbst weist dabei keine schneidenden Eigenschaften auf; vielmehr ist das durch die vorstehenden Elemente 4 erreichte Zupfen oder Pullen die wesentliche Eigenschaft des Querschneidemessers 1 bzw. des Messerkörpers 3 desselben.The
Zumindest in einem sich im Einsatz des Querschneidemessers 1 über die Öffnung 2a des Schneidgatters 2 bewegenden Bereich ist bei dem in den Figuren dargestellten Ausführungsbeispiel der Messerkörper 3 aus mehreren von einem zentralen Bereich 5 des Querschneidemessers 1 nach außen verlaufenden Speichen 6 und mehreren die Speichen 6 miteinander verbindenden Querstreben 7 gebildet. Die Speichen 6 verlaufen demnach in radialer Richtung des Messerkörpers 3 des Querschneidemessers 1, wohingegen die Querstreben 7 in Umfangsrichtung des Messerkörpers 3 verlaufen. Entgegen der Darstellung könnte auch auf die Querstreben 7 verzichtet werden, was die Masse des Messerkörpers 3 weiter verringern würde. Andererseits sorgen die Querstreben 7 für eine höhere Festigkeit des Messerkörpers 3. In einem solchen Fall, in dem keine Querstreben 7 vorhanden sind, sollten zwei oder mehr Speichen 6, vorzugsweise sechs oder mehr Speichen 6, noch bevorzugter acht oder mehr Speichen 6 vorgesehen sein. Im vorliegenden Fall sind zwölf Speichen 6 vorgesehen, die Anzahl der Speichen 6 hängt insbesondere auch vom Durchmesser des Querschneidemessers 1 ab. Eine größere Anzahl an Speichen 6 verringert die Gefahr, dass größere Stücke des Lebensmittels zwischen denselben hindurchtreten und gegebenenfalls nicht wie gewünscht bearbeitet werden.At least in a region that moves over the opening 2a of the
Auf diese Art und Weise ergeben sich zwischen den Speichen 6 und den Querstreben 7 eine Vielzahl von Ausnehmungen 8, durch welche das Lebensmittel durch den Messerkörper 3 des Querschneidemessers 1 hindurchgelangen kann. Dies führt zu einer deutlich verringerten Verschmutzung des Querschneidemessers 1, wodurch dieses über einen längeren Zeitraum als bislang ohne intensivere Reinigung benutzt werden kann. Die Ausnehmungen 8 sind selbstverständlich auch dann vorhanden, wenn auf die Querstreben 7 verzichtet wird.In this way, a large number of

Im dargestellten Ausführungsbeispiel sind die vorstehenden Elemente 4 auf sämtlichen Speichen 6 und lediglich auf der äußersten, die Speichen 6 miteinander verbindenden Querstrebe 7 angeordnet. Dadurch, dass sich auf den weiteren Querstreben 7 keine der vorstehenden Elemente 4 befinden, können diese mit einer geringeren Breite ausgeführt werden, was zur Vergrößerung der Fläche der Ausnehmungen 8 beiträgt. Selbstverständlich ist es jedoch auch möglich, die vorstehenden Elemente 4 auch auf weiteren Speichen 6 und/oder Querstreben 7 anzubringen. Des Weiteren sind auch andere Anordnungen der vorstehenden Elemente 4 auf dem Messerkörper 3 denkbar.The protruding
