DD205063A1 - METHOD AND DEVICE FOR PORKING PIGS - Google Patents

Abstract

Methods and devices for pricking pigs are in a known manner from a hollow knife carousel, in which the hollow knife must be inserted by hand into the aorta of the pig. This fatiguing and not dangerous work should be done according to the invention in such a way that the lancing does not take place on the hanging pig, but in the brewing basket, which transports the pig in a horizontal position. The Bruehkorb runs through a partial circle, under which a Hohlmessertraeger is arranged with spring-loaded hollow blades. The blood is withdrawn via the hollow blades of the hollow axis of the knife carrier and a vacuum line. A disinfecting bath below the knife carrier and a metering device for an anticoagulant complete the invention.

Method and device for pricking pigs Field of application of the invention

The invention finds application in the meat industry, especially in pig slaughtering.

Characteristic of the known technical solutions

In known manner, the pigs are after being stunned, chained to a hind leg and fed via a lift a continuous conveyor and the Ste.chstation.

The latest equipment uses hollow knives mounted on a carousel-like support with a vacuum pump via a blood-withdrawal hose. As a rule, a blood preserving agent or anticoagulant is also added at this point in a metered manner. The site at which the hollow knife is to be driven into the aorta has a radial and in the carcass axis a scattering area, which is used. The tip of the hollow knife can therefore also flat and spade-shaped broad his is not a "lancing carousel" used, but as widespread, the pigs stuck in a hanging state, runs blood over the head of the pig, which is hygienically not beneficial.

The work at the lancing station is heavy, tiresome and not without danger, since with insufficient stunning of the pig this moves violently and for example the hollow knife can not be inserted with security.

Another disadvantage is that the hollow blades can not be cleaned after piercing, so that there is a possibility that sick and healthy animals, this finding will be made later at a later date, with the same diameter.

Object of the invention

It is an object of the invention to perform the stinging and bleeding of pigs safely and without physical stress in the horizontal position of the pig.

Explanation of the essence of the invention

The invention is based on the object regardless of the size of the pig, the hollow knife mechanized stabbed into the aorta and to keep the axial and radial spreading area of the puncture site by exact positioning of the pig in close tolerances and to clean the hollow knife after each stitch and disinfect. According to the invention, this object is achieved by the carcass being moved in a horizontal position on a pitch circle track on a arranged below the pitch circle turret, rotatable hollow blade carrier whose rash knife at the beginning of the pitch circle track and through the hollow axis of Messäräger3, which is in operative connection with a vacuum pump, the blood is pumped off, while at the end of the partial circular path, the hollow knife is returned to the starting position and immersed in a disinfecting solution.

It is also part of the invention that a preservative is added simultaneously in a known manner during blood withdrawal.

Furthermore, it is part of the invention that the peripheral speed of the hollow blades in the orbit corresponds to the speed of the continuous conveyor with the brewing baskets.

The device according to the invention for carrying out the method consists of a star-shaped revolver-type hollow blade carrier with a hollow axis to which the hollow blades are axially movably mounted in flanged pipe guides and peder elements are located between the hollow blade and pipe guides and a continuous conveyor runs in a partial circular path over the hollow blade carrier. It is also part of the invention that the distance of the extended located on a circular path hollow blade corresponds to the distance of the brewing baskets.

Furthermore, it is part of the invention to provide the hollow blade with a stop for the penetration depth and a closure for the vacuum line.

Ultimately, part of the invention to arrange a disinfectant bath and a metering device for an anticoagulant below the hollow blade carrier.

embodiment

The invention will be explained in more detail by the accompanying drawings, which is an embodiment. 1 denotes the continuous conveyor on which hori

oO zontaler location the stunned pigs are transported in a brewing basket 6.

The transport path of the continuous conveyor 1 extends above the hollow blade carrier 2 in a partial circular path 12. The hollow blade carrier 2, the hollow blades are arranged in pipe guides 3.

239935 1

Between the stops 7 and the pipe guides 3 springs 5 are provided. The hollow blade carrier 2 has a hollow shaft 8, to which the vacuum line 9 and a metering device 11 for the anticoagulant is connected. With 10, the disinfectant bath is designated.

The, in the not belonging to the subject invention stunning bay, placed in the brewing basket 6 pigs are brought by temporary inclination of the brewing basket 6 with the head in a conically arranged positioning cone and transported horizontally in this position on a continuous conveyor 1.

As soon as the Brühkorii 6 with the pig is on this pitch circle 12, the lock not shown for the hollow blade 4 is released and the spring 5 drives the hollow blade 4 in the aorta. The blood is sucked through the vacuum line 9 and through the hollow shaft 8

 At the same time, an anticoagulant is added to the blood by the metering device 11.

The hollow knife pierced into the aorta follows the partial circular path 12 until the blood is completely withdrawn and is braced and locked against the spring 5 in a manner not shown, for example by run-on rails or pneumatically. On the way back to the triggering position for the lancing process, the hollow knife 4 passes through a disinfecting bath 10

 For the event of an accident that no pig is in the brewing basket 6, the hollow knife 4 closes the vacuum line 9. The penetration depth of the hollow blade 4 is fixed by a stop 7.
