Description

METHOD FOR SLAUGHTER LIVESTOCK AM) APPARATUS THEREOF

TECHNICAL FIELD

The present invention relates generally to a method for slaughtering livestock which provides meat for eating, such as cattle, pigs, horses, goats, or the like, and an apparatus thereof, and more particularly to a method for slaughtering livestock which is capable of cutting a blood vessel around the neck of the livestock in order to let the blood discharge completely while the organ or the gullet is not damaged and of pressing space where the air in the organ is ventilated to reduce rapidly the ventilation of the air in the organ, so that good quality, delicious meat with good color and good preservation is obtained, and an apparatus thereof .

BACKGROUND ART ^•

Generally, livestock is slaughtered by a blowing method, an electric shock or C0₂ method. As a result, dead blood may be created in the course of the slaughtering work, recognition system, of cells may not be operated, or the amount of C0₂ may be increased in the blood. Also, meat may be covered with the color of blood, stink of a bloody smell, and change in color and quality, since the blood is penetrated into the meat. Furthermore, taste of the meat may be of low grade since dead blood which changes into a hazardous material is mixed. In order to eliminate the aforesaid drawbacks, there has been proposed an method for putting the livestock in a state of suspended animation to obtain good quality meat when a neck or an artery of the livestock to be slaughtered is cut in order to let the blood discharge out.

With the aforesaid method, the effect of discharging the blood out is expected to some extent. However, if the livestock is cut in the neck while it is in a state of suspended animation by means of mechanical, chemical or electrical methods, there is enzyme cleared away from the blood to which the oxygen is not supplied and there is poisonous matter, such as promine, which is harmful to the liver, and waste matter contained in the blood, which turn into septic matter. Consequently, the oxygen is not supplied into the main cell membrane, and no production which is generated in each cell is treated. Moreover, defence of the recognition system of the cell membrane to which the oxygen is not supplied is broken down, and the blood which is dead by the means of the pressure applied into the blood vessel, which contaminates the air .

When the livestock is cut in the neck while it is not in a state of suspended animation, it always breathes in while it shrinks back. As a result, the cut larynx and the cut organ are drawn in toward the body, and the discharging blood is gathered around them. This blood is penetrated into the lungs when a breath is taken.

The penetrated blood prevents the supply of the oxygen from the lungs, and conveyed . to all of the body through the heart. As a result, the defense of the cell membrane which the dead blood passes through is broken down, and the meat is contaminated, which occurs because complete discharging of the blood is not carried out rapidly and it takes time to let the blood discharge out.

On account of the aforesaid, the inventor has proposed a method for slaughtering livestock by which the blood is discharged out as the blood in the blood vessel is squeezed to obtain good quality meat. For the aforesaid method, however, the organ is cut, and an external ventilation system is connected to the cut organ, into which the air is supplied. Consequently, it is required to make sure that any foreign substance does not enter the organ.

DISCLOSURE OF THE INVENTION

Therefore, it is an object of the present invention to provide a method and apparatus by which a blood vessel around the neck of a livestock is cut in order to let the blood discharge out while the gullet and the organ is not damaged, and the ventilation of the air in the organ is reduced rapidly, and subsequently muscle movement is caused by action of breathing, which press the blood vessels, so that the blood is discharged completely, to eliminate the aforesaid drawbacks .

To accomplish the object, the present invention provides a method for slaughtering livestock wherein a blood vessel around the neck of a livestock is cut in order to let the blood discharge out while the gullet and the organ must be held in order to make sure that the organ or the gullet is not damaged, space where the air in the organ is ventilated is pressed in order to make sure that the ventilation of the air in the organ is reduced rapidly, and subsequently muscle movement is caused due to difficulty in breathing, which press the blood vessels in the tissue, so that the blood in the capillary vessel is discharged completely.

BRIEF DESCRIPTION OF THE DRAWINGS

The above and other objects, features and advantages of the present invention will be apparent for the following detailed description of the preferred embodiment of the invention in conjunction with the accompanying drawings, in which:

Fig. 1 is a plan view showing action of contraction plates according to the present invention;

Fig. 2 is an illustrational view showing entire fixing frame according to the present invention; and Fig. 3 is a view showing pliers according to the present invention.

BEST MODE FOR CARRYING OUT OF THE INVENTION

After the legs of a livestock to be slaughtered are tied up, the livestock is hung up by the pulling cable of a suspension system, which generally comprises a pulley and a motor, such that the head of the animal is put down. Afterwards, the head of the livestock is fixed up by a fixing frame 10 of the present invention, which is constructed in the form of a vice. The fixing frame 10 of the present invention comprises a fixed plate 11 and a moving plate 12. The fixed plate 11 has a contraction part 11a and the moving plate 12 has a contraction part 12a. The contraction part 11a of the fixed plate 11 is opposite to the contraction part 12a of the moving plate 12. The moving plate 12 moves to the fixed plate 11 by means of transferring means, which comprises a piston rod 14 connected to the read end of the moving plate 12. The piston rod 14 is advanced or retracted by means of the action of a cylinder 13. Otherwise, a transferring threaded bar may be connected to the moving plate, which is then able to move by means of a manual handle, a motor drive, or a hydraulic action. The contraction parts 11a and 12a may be constructed in several forms, such as hemispherical grooves, square grooves, a plurality of projections or holes, which are used to fix the livestock without any damage. It should be noted that such forms fall into the scope of the present invention.

After the head of the livestock is fixed by the fixing frame as described above, a blood vessel around the neck of the livestock is cut by means of a sharp edged knife. At this time, the gullet and the organ just inside the larynx in the organs between the epiglottis and the. lungs must be held by the hand, and then the blood vessel of the rear part must be cut up to the bone of the neck to let the blood discharge, in order to make sure that any organ or the gullet is not be cut. At the same time, the space where the air in the organ is ventilated is pressed by means of pliers 20 according to the present invention in order to make sure that the ventilation of the air in the organ is reduced rapidly. The pliers 20 of the present invention has contraction controlling pieces 21 and 21' formed to its front ends. The contraction state of the pliers 20 is maintained by means of elastic action of a spring 22. The amount of the contraction of the pliers 20 is controlled depending upon position of the contraction surfaces of the contraction controlling pieces 21 and 21' . The ventilation of the air in the space near the organ contracted by the pliers 20 is reduced rapidly, and subsequently muscle movement is caused due to difficulty in breathing so that the blood remained in capillary vessels is discharged out . As mentioned above, the movement of the body is caused in the course of the air ventilation in the narrow space, and afterwards the blood is discharged out rapidly when discharging the blood from , the body. As a result, the livestock is not given any stress, which means a easy death. It is because the stress is generated only when the blood is in the body.

The time for discharging the blood is four or five minutes after the blood vessel is cut, and within this time the livestock may reach to brain death, by which nerve cells are dead. Consequently, complete discharging of the blood is accomplished.

INDUSTRIAL APPLICABILITY

According to the present invention as mentioned above, it is possible to obtain pure meat from which the blood is discharged out, to eliminate a bloody smell from the meat, to keep the meat for a long time while the meat is not changed in terms of color and quality, to obtain quality meat, and carry out the slaughtering work conveniently and sanitarily.
