Abstract

Equipment for stunning animals for slaughter uses an electric shock method. Prevention of damage to the animal meat is avoided by careful location of the electrodes in (i) the eye and brain area (ii) in the heart area, where electrical resistance is lowest. The electrode in the heart area is aligned at an angle and on the left side. Operation of electrodes can be manual or automatic and the exact position of the animal is determined by sensors. Equipment is adjustable for both small and large cattle. USE/ADVANTAGE - For stunning cattle, e.g. pigs, prior to slaughter. Precise electrode location in areas of low electrical resistance allows the use of lower voltages and therefore reduces damage to the animal meat.

Description

Die Erfindung bezieht sich auf eine Betäubungsanlage der im Patentanspruch 1 der Hauptanmeldung P 39 09 833.8-23 ange­ gebenen Gattung.The invention relates to a stunning system in claim 1 of the main application P 39 09 833.8-23 given genus.

Es ist bekannt, Schlachtvieh, z.B. Schweine, durch Elektroschock zu betäuben, wobei relativ hohe Spannungen verwendet werden, die zu Schlachtschäden und damit zu einer Verminderung der Fleischqualität führen.It is known to slaughter cattle e.g. Pigs, by Stun electric shock, taking relatively high voltages are used, which lead to battle damage and thus to a Reduce meat quality.

Die Hauptanmeldung P 39 09 833.8-23 beschreibt bereits eine Betäubungsanlage bei der mit niedrigeren Strömen (unter 300 Volt) gearbeitet werden kann und mit der eine wesentliche Verbesserung der Fleischqualität erzielt wird.The main application P 39 09 833.8-23 already describes one Stunning system at the one with lower currents (below 300 volts) can be worked and with the one essential Improvement in meat quality is achieved.

Aufgabe der vorliegenden Erfindung ist eine weitere Verbesserung insofern, als durch genaueres Ansetzen der einen Elektrode an einen Körperbereich des Tieres, der den geringsten elektrischen Widerstand hat, so daß mit Spannungen unter 120 Volt und mit relativ geringer Stromstärke gearbeitet werden kann, eine optimale Fleischqualität erzielt wird, da die Tiere völlig schmerz- und krampffrei betäubt werden.Another object of the present invention Improvement in so far as by more precisely starting the one Electrode to an area of the animal's body that is the least has electrical resistance, so that with voltages below 120 Volts and with a relatively low current optimal meat quality is achieved, because the animals are completely anesthetized without pain and cramp.

Ein wesentliches Merkmal der erfindungsgemäßen Betäubungsanlage ist das Ansetzen der Elektroden, ob manuell oder automatisch, im Augen/Hirn-Bereich einerseits und im unmittelbaren Herz-Bereich andererseits, da dort die Haut des Schlachttieres, insbesondere des Schweines, am dünnsten und damit der elektrische Widerstand am geringsten ist, so daß mit Spannungen unter 120 Volt gearbeitet werden kann, wobei die Tiere nach der nur höchsten 5 Sekunden dauernden Betäubung völlig ruhig liegen.An essential feature of the invention Stunning system is the application of the electrodes, whether manual or automatically, in the eye / brain area on the one hand and in the immediate heart area, on the other hand, because that's where the skin is the slaughtered animal, especially the pig, is the thinnest and so that the electrical resistance is the lowest, so that you can work with voltages below 120 volts, whereby the animals after the anesthesia lasting only 5 seconds lie completely still.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Dabei zeigtAn embodiment of the invention is in the Drawing shown. It shows

Fig. 1 in Seitenansicht schematisch die Betäubungsanlage und Fig. 1 in side view schematically the stunning system and

Fig. 2 eine Ansicht in Richtung des Pfeiles II in Fig. 1. Fig. 2 is a view in the direction of arrow II in FIG. 1.

Die in der Zeichnung dargestellte manuell bedienbare Betäubungsanlage für Schlachtvieh, z.B. Schweine 1, besteht im wesentlichen aus einem Treibgang 2 und einer Betäubungsstation 3. In der Betäubungsstation 3 ist ein Rücken-Niederhalter 5 durch Druckmittelzylinder 6 höheneinstellbar angeordnet. Ferner befinden sich in der Betäubungsstation 3 zwei V-förmig zueinander angeordnete Förderbänder 7, die über je einen stufenlos regelbaren Hydromotor 8 synchron angetrieben werden. Im Boden der Betäubungsstation 3 ist ein Einlaufblech 9 vorgesehen, das über Sensoren, z.B. Lichtschranken, oder durch Gewichtsmessung bei richtiger Position eines Schweines 1 in Förderrichtung schräg nach unten geklappt wird, so daß das Schwein 1 nur noch seitlich auf den Förderbändern 6 hängt und somit in relativ ruhiger Stellung zum Ende der Betäubungsstation 3 befördert wird. Dort befindet sich eine Bedienungsperson, die Zugang zu Schaltern hat, um ggf. den Rücken-Niederhalter 5 oder die Hydromotoren 8 für die Förderbänder 7 zu steuern. Bei richtiger Positionierung des Schweines 1 setzt die Bedienungsperson eine von zwei Elektroden, z.B. die positive Elektrode 12, im Augen/Hirn-Bereich des Schweines 1 an und schaltet die zweite Elektrode, z.B. die negative Elektrode 14, und den Strom ein, wobei die negative Elektrode 14 durch einen Druckmittelzylinder 15 im Herzbereich des Schweines 1 von schräg links oben angesetzt wird. Die Betäubungszeit wird über Zeitglieder geregelt und beträgt höchstens 5 Sekunden. Das betäubte Schwein 1 rutscht über eine Auswurfrutsche 16 auf ein Entblutungsband 17 zur liegenden Entblutung.The manually operated stunning system for slaughter cattle, for example pigs 1 , shown in the drawing essentially consists of a drive duct 2 and a stunning station 3 . In the anesthetic station 3 , a back hold-down 5 is arranged height-adjustable by means of pressure medium cylinders 6 . Furthermore, there are two conveyor belts 7 arranged in a V-shape with respect to one another in the stunning station 3, each of which is driven synchronously via a continuously variable hydraulic motor 8 . In the bottom of the stunning station 3 , an inlet plate 9 is provided, which is tilted downwards via sensors, for example light barriers, or by weight measurement when a pig 1 is in the correct position in the conveying direction, so that the pig 1 only hangs laterally on the conveyor belts 6 and thus is transported to the end of the stunning station 3 in a relatively quiet position. There is an operator who has access to switches to control the back hold-down 5 or the hydraulic motors 8 for the conveyor belts 7 , if necessary. With the pig 1 correctly positioned, the operator places one of two electrodes, for example the positive electrode 12 , in the eye / brain area of the pig 1 and switches on the second electrode, for example the negative electrode 14 , and the current, the negative Electrode 14 is attached by a pressure medium cylinder 15 in the heart area of pig 1 from obliquely top left. The stunning time is regulated by timers and is a maximum of 5 seconds. The anesthetized pig 1 slides over an ejection chute 16 onto a bleeding belt 17 for lying bleeding.

Die positive Elektrode 12 wird durch einen Druckmittelzylinder 19 angesetzt, nachdem mit der Elektrode eine halbschalenförmige Gittermaske 20, die nach unten offen ist, durch einen Zylinder 21 über den Kopf des Schweines 1 heruntergefahren worden ist. Gleichzeitig mit der positiven Elektrode 12 wird über einen Kontakt in der Gittermaske 20 auch die negative Elektrode 14 durch den Druckmittelzylinder 15 von links an den Herzbereich des Schweines 1 herangeführt. Nach einer Körper-Widerstandsmessung wird die Betäubung eingeleitet. Dann werden die Elektroden 12, 14 und die Gittermaske 20 wieder zurückgefahren, das betäubte Schwein 1 wird durch die Förderbänder 7 weiterbefördert, bis es über die Auswurfrutsche 16 auf das Entblutungsband 17 zum Abstechen gelangt.The positive electrode 12 is attached by a pressure medium cylinder 19 after the electrode has been used to move a half-shell-shaped grid mask 20 , which is open at the bottom, through a cylinder 21 over the head of the pig 1 . Simultaneously with the positive electrode 12 , the negative electrode 14 is also brought through the pressure medium cylinder 15 from the left to the heart area of the pig 1 via a contact in the grid mask 20 . The anesthesia is initiated after a body resistance measurement. Then the electrodes 12 , 14 and the grid mask 20 are moved back again, the anesthetized pig 1 is conveyed on by the conveyor belts 7 until it reaches the bleeding belt 17 via the ejection chute 16 for tapping.
