Description

Die Erfindung betrifft eine Vorrichtung zum Zerkleinern eines Zerkleinerungsgutes, insbesondere für die Fleischverarbeitung, mittels zumindest einer in einem Gehäuse angeordneten Lochplatte und dieser an einer Drehwelle zugeordneten Schneidklinge, wobei die Drehwelle die Lochplatte durchsetzt und in diesem Bereich zwischen Lochplatte und Drehwelle durch Einhaltung eines Abstands ein Spalt ausgebildet ist.The invention relates to a device for crushing a comminuted material, in particular for meat processing, by means of at least one arranged in a housing perforated plate and this associated with a rotary shaft cutting blade, the rotary shaft passes through the perforated plate and in this area between the perforated plate and rotating shaft by maintaining a distance Gap is formed.

Stand der TechnikState of the art

Derartige Vorrichtungen sind in vielfältiger Form und Ausgestaltung bekannt und gebräuchlich. So beschreiben die DE 39 15 409 C2 und auch die DE 199 60 409 A1 eine solche Vorrichtung, bei welcher mehrere Schneidsätze vorgesehen sind, die jeweils aus einer Lochplatte und einem Schneidkopf bestehen. Der Schneldkopf wiederum ist mit Schneidklingen versehen. Schneidgut wird während dem Eindrücken in Bohrungen der jeweiligen Lochplatten durch die Schneidklingen zerkleinert, wobei die Lochplatten still stehen, während die Schneidköpfe mit einer Antriebswelle drehen. Da die Lochplatten in Bearbeltungsrichtung des Schneidgutes mit immer geringer werdenden Bohrungsdurchmessern versehen sind, wird das Schneidgut immer weiter zerkleinert, bis es schliesslich zu einem Auswerfer gelangt. Dieser führt das zerkleinerte Gut einer nicht näher gezeigten Auswurföffnung zu.Such devices are known in many forms and configurations and in use. So describe the DE 39 15 409 C2 and also the DE 199 60 409 A1 Such a device in which a plurality of cutting sets are provided, each of a perforated plate and a cutting head consist. The Schneldkopf in turn is provided with cutting blades. Cutting material is crushed during the impressions in holes of the respective perforated plates by the cutting blades, the perforated plates stand still, while the cutting heads rotate with a drive shaft. Since the perforated plates are provided in the machining direction of the material to be cut with ever-decreasing bore diameters, the material to be cut is further and further crushed until finally it reaches an ejector. This leads to the shredded material to an ejection opening not shown in detail.

Nachteilig hierbei Ist Jedoch, dass aufgrund der Schwingung der Antriebswelle mit den Schneldköpfen insbesondere zwischen einem Innendurchmesser der Lochplatte/n und einem Aussendurchmesser der Drehwelle oder des Auswerfers ein Spalt vorgesehen sein muss. Dieser muss ausreichend gross sein, damit gewährleistet werden kann, dass ein Materialabrieb an dem Innendurchmesser der Lochplatte und damit auch eine Verunreinigung des Schneidgutes möglichst gering gehalten wird, welcher durch die Schwingung der Antriebswelle mit den Schneidköpfen zwangläufig gegeben ist. Allerdings wird somit durch diesen Spalt noch unzerkleinertes Schneidgut gedrückt, so dass sich In dem vollständig zerkleinerten Schneidgut auch Grobpartikel befinden. Dies ist höchst unerwünscht.The disadvantage here is, however, that due to the vibration of the drive shaft with the Schneldköpfen in particular between an inner diameter of the perforated plate / n and an outer diameter of the rotary shaft or the ejector, a gap must be provided. This must be sufficiently large, so that it can be ensured that a material abrasion on the inner diameter of the perforated plate and thus contamination of the material to be cut is minimized, which is inevitably given by the vibration of the drive shaft with the cutting heads. However, uncut material to be cut is thus pressed through this gap, so that coarse particles are also present in the completely comminuted material to be cut. This is highly undesirable.

Versuche, diesen Spalt zu verringern, indem auf eine Stahlnabe des Auswerfers ein Kunststoffring gepresst wurde, führten zu dem Nachteil, dass der Kunststoffring durch die Schwingung der Antriebswelle mit den Schneidköpfen einem hohen Verschlelss unterlag, was unter anderem aus Kostengründen ebenfalls unerwünscht ist.Attempts to reduce this gap by pressing on a steel hub of the ejector a plastic ring, to the disadvantage that the plastic ring was subject by the oscillation of the drive shaft with the cutting heads a high Verschlelss, which is also undesirable for cost reasons.

Eine entsprechende Vorrichtung wird in der DE 10 49 729 offenbart. In dieser wird der Ringspalt zwischen Lochplatte und der Ausnehmung in der Antriebswelle mit einer Dichtung, die vom Zerkleinerungsgut selbst geschmiert wird, verschlossen. Um Verklemmungen zu vermeiden, ist die Dichtung elastisch ausgebildet. Um diese Elastizität zu erhöhen, sind im Innenraum der Dichtung Federn angeordnet. Dadurch passt sich die Dichtung in einem gewissen Rahmen den axialen Bewegungen der Drehachse selbsttätig an.A corresponding device is in the DE 10 49 729 disclosed. In this, the annular gap between the perforated plate and the recess in the drive shaft with a seal, which is lubricated by the crushing material itself, closed. To avoid jamming, the seal is elastic. To increase this elasticity, are in the interior of the Seal springs arranged. As a result, the seal adapts itself to the axial movements of the axis of rotation to a certain extent.

Aufgabe der ErfindungObject of the invention

Aufgabe der vorliegenden Erfindung ist es, die oben genannten Nachteile zu beseitigen und eine Vorrichtung der o.g. Art zu schaffen, bei welcher die Qualität des erhalten Produktes wesentlich verbessert wird.The object of the present invention is to eliminate the abovementioned disadvantages and to provide a device of the above-mentioned type. To create a way in which the quality of the product obtained is significantly improved.

Lösung der AufgabeSolution of the task

Zur Lösung dieser Aufgabe führen die Merkmale des kennzeichnenden Teils des Anspruchs 1.To achieve this object, the features of the characterizing part of claim 1.

Inbesondere ist der Spalt zwischen Lochplatte und Drehwelle durch eine Dichtung verschlossen, wobei die Dichtung radial beweglich angeordnet ist.In particular, the gap between the perforated plate and the rotary shaft is closed by a seal, wherein the seal is arranged radially movable.

Diese Dichtung kann unterschiedliche Ausgestaltungen aufweisen. So ist bei einem Ausführungsbeispiel daran gedacht, die Dichtung als Dichtring auszubilden, welcher In einem Innendurchmesser der Lochplatte festgelegt ist und in eine Nut der Drehwelle- bzw, eines Auswerferes eingreift. Zwischen einem Boden der Nut und dem Dichtring besteht jedoch ausreichend Spiel, so dass sich der Dichtring bei einer Schwingung der Drehwelle radial bewegen kann. Der Spalt kann auf diese Welse bestehen bleiben, ohne dass Grobanteile in das bereits zerkleinerte Brät geraten können.This seal may have different configurations. Thus, in one embodiment, it is thought to form the seal as a sealing ring, which is fixed in an inner diameter of the perforated plate and engages in a groove of the Drehwelle- or, an ejector. Between a bottom of the groove and the sealing ring, however, there is sufficient clearance, so that the sealing ring can move radially at a vibration of the rotary shaft. The gap can remain on this catfish, without coarse particles can get into the already comminuted meat.

Bei einem weiteren Ausführungsbeispiel der Dichtung ist die Dichtung ebenfalls als Dichtring ausgestaltet. Lediglich die Anordnung des Dichtringes hat sich verändert. Hier ist der Dichtring nun fest mit der Drehwelle bzw. dem Auswerfer verbunden und greift In eine Nut der Lochplatte ein. Erneut hat der Dichtring in der Nut ausreichend Spiel , so dass sich der Dichtring bei der Schwingung der Drehwelle radial bewegen kann.In a further embodiment of the seal, the seal is also designed as a sealing ring. Only the arrangement of the sealing ring has changed. Here, the sealing ring is now firmly connected to the rotary shaft or the ejector and engages in a groove of the perforated plate. Again, the sealing ring in the groove has enough clearance, so that the sealing ring can move radially in the oscillation of the rotary shaft.

Anstelle einer Nut in der Lochplatte oder der Drehwelle bzw, dem Auswerfer kann selbstverständlich auch eine Ecksicke od. dgl. vorgesehen werden, In welche der Dichtring eingreift, Im Falle einer Ecksicke sollte allerdings beispielsweise ein Haltering vorgesehen sein, um zu verhindern, dass der Dichtring aus der Ecksicke rutscht. Weitere Ausgestaltungen sind denkbar und sollen von der vorliegenden Erfindung umfasst sein.Instead of a groove in the perforated plate or the rotary shaft or the ejector, of course, a corner bead od. Like. Be provided, in which the sealing ring engages, In the case of a corner bead, however, for example, a retaining ring should be provided to prevent the sealing ring slips out of the corner bead. Further embodiments are conceivable and should be encompassed by the present invention.

Weiterhin ist denkbar, die Dichtung weder in dem Innendurchmesser der Lochplatte noch auf dem Aussendurchmesser der Drehwelle bzw. des Auswerferes festzulegen, Stattdessen kann die Dichtung sozusagen in Ausnehmungen bzw. Nuten schwimmen, welche in dem Innendurchmesser der Lochplatte undloder dem Aussendurchmesser der Drehwelle bzw. des Auswerferes angeordnet sind. Hierbei wird ebenfalls eine axiale Abdichtung gewährleistet, der notwendige Spalt kann bestehen bleiben und trotzdem ist ausreichend Spiel vorhanden, so dass sich die Dichtung bei der Schwingung der Drehwelle radial bewegen kann. Auch diese Möglichkeit soll von der vorliegenden Erfindung umfasst sein.Furthermore, it is conceivable to set the seal neither in the inner diameter of the perforated plate nor on the outer diameter of the rotary shaft or the ejector, instead, the seal can speak in Recesses or grooves float, which are arranged in the inner diameter of the perforated plate andlor the outer diameter of the rotary shaft and the ejector. Here, an axial seal is also ensured, the necessary gap can remain and still sufficient clearance is present, so that the seal can move radially in the vibration of the rotary shaft. This possibility should also be encompassed by the present invention.

Ein weiteres Ausführungsbeispiel der Dichtung sieht eine Gleitringdichtung vor, welche zwischen der Lochplatte und dem Auswerfer angeordnet ist.
Weiter Ausgestaltungen und Anordnungen der Dichtung sind denkbar und sollen von der vorliegenden Erfindung umfasst sein. So ist beispielsweise daran gedacht, eine derartige Dichtung nicht nur bei der letzten Lochplatte in Verbindung mit dem Auswerfer vorzusehen, sondern bereits bei den vorherigen Lochplatten in Verbindung mit der Drehwelle. Denn auch hier soll verhindert werden, dass Grobpartikel, welche dem Zerkleinerungsgrad der jeweils folgenden Lochplatte nicht entsprechen, dennoch durchgepresst werden.Another embodiment of the seal provides a mechanical seal, which is arranged between the perforated plate and the ejector.
Further refinements and arrangements of the seal are conceivable and are intended to be encompassed by the present invention. For example, it is thought to provide such a seal not only in the last perforated plate in conjunction with the ejector, but already in the previous perforated plates in conjunction with the rotary shaft. For here too it is to be prevented that coarse particles which do not correspond to the degree of comminution of the respective following perforated plate are nevertheless pressed through.

Wichtig bei den unterschiedlichen Möglichkeiten der Ausgestaltung und Anordnung der Dichtung ist, dass eine axiale Abdichtung des Spaltes in beide Richtungen gewährleistet wird, so dass zum einen verhindert wird, dass Grobantelle in das bereits zerkleinerte Brät geraten. Zum anderen muss sich der Dichtring bei der Schwingung der Drehwelle radial anpassen können, ohne dass ein Materialabrieb der Lochplatte oder ein Verschleiss der Dichtung gegeben ist.Important in the different possibilities of the design and arrangement of the seal is that an axial seal of the gap is ensured in both directions, so that on the one hand prevents Grobantelle get into the already comminuted meat. On the other hand, the sealing ring must be able to radially adapt to the vibration of the rotary shaft, without that a material abrasion of the perforated plate or a wear of the seal is given.

Die einzelnen Dichtungen bestehen bevorzugt aus Kunststoff, Keramik oder Metall. Im Falle der Herstellung aus Kunststoff wird insbesondere glasfaserverstärktes Teflon bevorzugt. Als Metall ist Bronze denkbar, da dieses in der Lebensmittelindustrie zugelassen ist. Weiter Materialien sind denkbar und sollen von der vorliegenden Erfindung umfasst sein.The individual seals are preferably made of plastic, ceramic or metal. In the case of production from plastic, in particular glass fiber reinforced Teflon is preferred. As a metal, bronze is conceivable, since this is approved in the food industry. Further materials are conceivable and are intended to be encompassed by the present invention.

  • FIG. 3 enlarged shown sections of the device according to FIG. 1 with a further embodiment of a seal according to the invention.

Gemäss Figur 1 ist von einer Vorrichtung zum Zerkleinern eines Zerkleinerungsgutes, etwa entsprechend der DE 39 15 409 C2 , Im wesentlichen nur ein Zerkleinerungsbereich 1 gezeigt. Dieser Zerkleinerungsbereich 1 weist eine Eintrittsöffnung 2 für das Zerkleinerungsgut sowie einen Auswurfbereich 3 auf, der im vorliegenden Ausführungsbeispiel von einer Haube 4 abgedeckt ist.According to FIG. 1 is of a device for crushing a crushed material, approximately corresponding to DE 39 15 409 C2 , Essentially only one crushing area 1 shown. This comminuting area 1 has an inlet opening 2 for the comminuted material and an ejection area 3, which in the present exemplary embodiment is covered by a hood 4.

Das Zerkleinerungsgut wird von der Eintrittsöffnung 2 zum Auswurfbereich 3 parallel zu einer Längsachse 5 einer Drehwelle 6 gefördert, wobei die Drehwelle 6 durch die Eintrittsöffnung 2 In ein etwa zylindrisches Gehäuse 7 einragt, welches einerseits mit einem Einlauftrichter 8 In Verbindung steht und andererseits von der Haube 4 abgedeckt ist.The comminuted material is conveyed from the inlet opening 2 to the ejection area 3 parallel to a longitudinal axis 5 of a rotary shaft 6, wherein the rotary shaft 6 protrudes through the inlet opening 2 into an approximately cylindrical housing 7, which is connected on the one hand with an inlet funnel 8 and on the other hand from the hood 4 is covered.

In dem Gehäuse 7 sind drei Schneidsätze A, B und C vorgesehen. Jeder Schneldsatz A, B und C besteht aus einer Lochplatte 9.1, 9.2 und 9.3 sowie einem Schneidkopf 10.1, 10.2 und 10.3, welcher Schneldklingen 11.1, 11.2 und 11.3 aufweist. Die Schneidklingen 11.1, 11.2 und 11.3 streifen an den Lochplatten 9.1, 9.2 und 9.3 entlang bzw. sind in einem Abstand etwa gleich Null entlang den Lochplatten 9.1, 9.2 bzw. 9.3 geführt. Bohrungen 12.3 in der Lochplatte 9.3 sind grösser als Bohrungen 12.2 in der Lochplatte 9.2. Diese sind wiederum grösser als Bohrungen 12.1 in der Lochplatte 9.1.In the housing 7, three cutting sets A, B and C are provided. Each quick set A, B and C consists of a perforated plate 9.1, 9.2 and 9.3 and a cutting head 10.1, 10.2 and 10.3, which Schneldklingen 11.1, 11.2 and 11.3. The cutting blades 11.1, 11.2 and 11.3 strip on the perforated plates 9.1, 9.2 and 9.3 along or are guided at a distance approximately equal to zero along the perforated plates 9.1, 9.2 and 9.3. Holes 12.3 in the perforated plate 9.3 are larger than holes 12.2 in the perforated plate 9.2. These are in turn larger than holes 12.1 in the perforated plate 9.1.

Die Schneidköpfe 10.1 bis 10.3 sitzen drehfest auf der Drehwelle 6 und drehen mit der Drehwelle 6 um die Längsachse 5. Die Lochplatten 9.1 bis 9.3 sind dagegen ortsfest in einem hülsenförmigen Stellkörper 13 angeordnet. Dieser sitzt wiederum in dem Gehäuse 7, wobei ein Aussengewindeabschnitt 14 an dem Stellkörper 13 in ein Innengewindeabschnitt 15 an dem Gehäuse 7 eingreift. Beim Drehen des Stellkörpers 13 kann dadurch dieser Stellkörper 13 in Richtung der Längsachse 5 bewegt werden, wobei die Lochplatten 9.1 bis 9.3 mitgenommen und hierdurch der Abstand jeder Lochplatte 9.1 bis 9.3 zu der entsprechenden Schneidklinge 11.1 bis 11.3 verändert wird.The cutting heads 10.1 to 10.3 are non-rotatably mounted on the rotary shaft 6 and rotate with the rotary shaft 6 about the longitudinal axis 5. The perforated plates 9.1 to 9.3, however, are stationary in a sleeve-shaped actuating body 13 is arranged. This in turn is seated in the housing 7, wherein an externally threaded portion 14 engages the adjusting body 13 in an internally threaded portion 15 on the housing 7. When rotating the adjusting body 13, this adjusting body 13 can thereby be moved in the direction of the longitudinal axis 5, wherein the perforated plates 9.1 to 9.3 taken and thereby the distance between each perforated plate 9.1 to 9.3 to the corresponding cutting blade 11.1 to 11.3 is changed.

Das Drehen des Stellkörpers 13 geschieht bevorzugt über ein nicht näher gezeigtes Schneckengetriebe oder auch einen Schrittmotor, auf dessen Abtriebswelle ein entsprechendes Ritzel sitzt, welches mit einer Verzahnung 16 eines Stirnrades 17 in Eingriff steht. Dieses Stirnrad 17 ist durch entsprechende Schrauben 18 mit dem Stellkörper 13 verbunden.The rotation of the actuator 13 is preferably done via a worm gear not shown in detail or a stepper motor, on the output shaft, a corresponding pinion is seated, which is in engagement with a toothing 16 of a spur gear 17. This spur gear 17 is connected by appropriate screws 18 with the actuating body 13.

Im vorliegenden Ausführungsbeispiel ragt vom Stirnrad 17 ein Innenflansch 19 in den Stellkörper 13 und bildet einen Ringanschlag 20.3 für die Lochplatte 9.3 aus. Andererseits trifft auf die Lochplatte 9.3 ein Distanzring 21.3 mit federgelagerten Druckbolzen 22.3. Diese Druckbolzen 22.3 drücken die Lochplatte 9.3 gegen den Ringanschlag 20.3, um eine sich ändernde Lochplattendicke zu korrigieren.In the present embodiment protrudes from the spur gear 17, an inner flange 19 in the actuating body 13 and forms an annular stop 20.3 for the perforated plate 9.3. On the other hand, meets the spacer plate 9.3 a spacer ring 21.3 with spring-loaded pressure pin 22.3. These pressure pins 22.3 push the perforated plate 9.3 against the ring stop 20.3 to correct a changing perforated plate thickness.

Der Distanzring 21.3 bildet wiederum einen Ringanschlag 20.2 für die Lochplatte 9.2 aus, die ebenfalls durch federgelagerte Druckbolzen 22.2 gegen diesen Ringanschlag 20.2 gedrückt wird.The spacer ring 21.3 again forms an annular stop 20.2 for the perforated plate 9.2, which is also pressed by spring-loaded pressure pin 22.2 against this ring stop 20.2.

Der Druckbolzen 22.2 befindet sich in einem weiteren Distanzring 21.2, der wiederum einen Ringanschlag 20.1 für die Lochplatte 9.1 ausbildet.The pressure pin 22.2 is located in a further spacer ring 21.2, which in turn forms a ring stop 20.1 for the perforated plate 9.1.

Den Abschluss der Schneidsätze A, B und C bildet dann ein in den Stellkörper 13 eingeschraubter Spannring 23.The conclusion of the cutting sets A, B and C then forms a screwed into the actuator body 13 clamping ring 23rd

Von der Haube 4 überdeckt, ist ein Auswerfer 25 vorgesehen, welcher mit der Drehwelle 6 vorzugsweise drehfest verbunden ist.Covered by the hood 4, an ejector 25 is provided, which is preferably rotatably connected to the rotary shaft 6.

Die Funktionsweise der vorliegenden Erfindung ist folgende:The operation of the present invention is as follows:

Zerkleinerungsgut, insbesondere Brät, wird durch die Eintrittsöffnung 2 eingeführt und gelangt in den Bereich des Schneidsatzes C. Die Lochplatte 9.3 steht still, während der Schneidkopf 10.3 mit der Drehwelle 6 dreht, so dass das Schneidgut während dem Eindrücken in die Bohrungen 12.3 durch die Schneidklingen 11.3 zerkleinert wird. In den Bohrungen 12.3 mit dem grössten Durchmesser findet eine grobe Vorzerkleinerung statt.Crushed, in particular meat, is introduced through the inlet opening 2 and enters the area of the cutting set C. The perforated plate 9.3 stands still while the cutting head 10.3 rotates with the rotary shaft 6, so that the material to be cut during the impressions in the holes 12.3 through the cutting blades 11.3 is crushed. In the holes 12.3 with the largest diameter, a rough pre-crushing takes place.

Von dem Schneidsatz C gelangt das Brät zu dem Schneidsatz B mit der Lochplatte 9.2 mit den Bohrungen 12.2 mittleren Durchmessers. Auch hier wird das Brät in diese Bohrungen 12.2 hineingedrückt und gleichzeitig durch die an der Lochplatte 9.2 entlangfahrenden Schneidklingen 11.2 zerkleinert.From the cutting set C, the sausage meat reaches the cutting set B with the perforated plate 9.2 with the bores 12.2 of medium diameter. Again, the sausage meat is pressed into these holes 12.2 and simultaneously crushed by the cutting blades 11.2 moving along the perforated plate 9.2.

Nunmehr gelangt das zu zerkleinernde Gut zum Schneidsatz A, in dem die Lochplatte 9.1 mit den Bohrungen 12.1 mit dem geringsten Durchmesser angeordnet ist. Auch hier wird das Brät in diese Bohrungen 12.1 hineingedrückt und beim Hineindrücken durch die Schneidklingen 11.1 weiter zerkleinert.Now the material to be crushed reaches the cutting set A, in which the perforated plate 9.1 is arranged with the holes 12.1 with the smallest diameter. Again, the sausage meat is pressed into these holes 12.1 and further crushed when pushed in by the cutting blades 11.1.

Schliesslich gelangt das zerkleinerte Gut in den Auswurfbereich 3, in dem es von dem Auswerfer 25 einer nicht näher gezeigten Auswurföffnung zugeführt wird.Finally, the comminuted material enters the ejection region 3, in which it is fed by the ejector 25 of an ejection opening not shown in detail.

Wird festgestellt, dass die Tätigkeit zwischen Schneidklingen und Lochplatten nicht mehr optimal ist, muss der Abstand zwischen Schneidklingen und Lochplatten verstellt werden. Hierzu wird der nicht näher gezeigte Antrieb in Tätigkeit gesetzt, so dass er über die Verzahnung 16 das Stirnrad 17 und mit dem Stirnrad 17 auch den Stellkörper 13 dreht. Dabei kämmt das Innengewinde 15 in dem Aussengewinde 14, so dass der Stellkörper 13 entlang der Längsachse 5 bewegt wird.If it is determined that the activity between cutting blades and perforated plates is no longer optimal, the distance between cutting blades and perforated plates must be adjusted. For this purpose, the drive not shown in detail is set in action, so that it rotates about the teeth 16, the spur gear 17 and the spur gear 17 and the adjusting body 13. In this case, the internal thread 15 meshes in the external thread 14, so that the adjusting body 13 is moved along the longitudinal axis 5.

Aufgrund der starken Schwingung der Drehwelle 6 mit den Schneidköpfen 10.1, 10.2 und 10.3 während der Zerkleinerungstätigkeiten muss zwischen einem Innendurchmesser 26 beispielsweise der Lochplatte 9.1 und einem Aussendurchmesser 27 des Auswerfers 25 ein Spalt 28 vorgesehen sein. Dies ist In Figur 2 deutlicher zu erkennen. Dieser Spalt 28 darf nicht zu klein sein, damit es an dem Innendurchmesser 26 der Lochplatte 9.1 keinen Materialabrieb gibt.Due to the strong vibration of the rotary shaft 6 with the cutting heads 10.1, 10.2 and 10.3 during the crushing activities must be provided between an inner diameter 26, for example, the perforated plate 9.1 and an outer diameter 27 of the ejector 25, a gap 28. This is in FIG. 2 to recognize more clearly. This gap 28 must not be too small so that there is no material abrasion on the inner diameter 26 of the perforated plate 9.1.

Um diesen Spalt 28 abzudichten, so dass durch ihn keine unzerkleinerten Grobanteile in das bereits zerkleinerte Gut gepresst werden, ist ein Dichtring 29.1 vorgesehen. Dieser Dichtring 29.1 Ist In dem Innendurchmesser 26 der Lochplatte 9.1 festgelegt und greift in eine Nut 30 des Auswerferes 25 ein und gewährleistet eine in beide Richtungen axiale Abdichtung zu dem Auswerfer 25 hin. Gleichzeitig hat der Dichtring 29.1 ausreichend Spiel In der Nut 30, so dass sich der Dichtring 29.1 bei Schwingung der Drehwelle 6 radial in der Nut 30 bewegen kann. Der Spalt 28 kann auf diese Welse bestehen bleiben, ohne dass Grobanteile in das bereits zerkleinerte Brät geraten können.In order to seal this gap 28, so that no uncut coarse fractions are pressed through it into the already comminuted material, a sealing ring 29.1 is provided. This sealing ring 29.1 is defined in the inner diameter 26 of the perforated plate 9.1 and engages in a groove 30 of the ejector 25 and ensures an axial in both directions seal to the ejector 25 out. At the same time, the sealing ring 29.1 has sufficient clearance in the groove 30, so that the sealing ring 29.1 can move radially in the groove 30 upon oscillation of the rotary shaft 6. The gap 28 can remain on this catfish without coarse particles can get into the already comminuted meat.

Gemäss der Figur 3 ist ein weiteres Ausführungsbeispieleiner Dichtung gezeigt. in Figur 3 ist lediglich die Anordnung eines Dichtringes 29.2 unterschiedlich. So sitzt der Dichtring 29.2 hier fest auf dem Aussendurchmesser 27 des Auswerfers 25 und greift in eine Nut 32 der Lochplatte 9.1 ein. In der Nut 32 hat der Dichtring 29.2 wiederum ausreichend Spiel, so dass sich der Dichtring 29.2 bei der Schwingung der Drehwelle 6 radial in der Nut 32 bewegen.According to the FIG. 3 another embodiment of a gasket is shown. in FIG. 3 only the arrangement of a sealing ring 29.2 is different. Thus, the sealing ring 29.2 sits firmly on the outer diameter 27 of the ejector 25 and engages in a groove 32 of the perforated plate 9.1. In the groove 32, the sealing ring 29.2 again has sufficient clearance, so that the sealing ring 29.2 move radially in the groove 32 during the oscillation of the rotary shaft 6.
