Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to an anesthesia method for slaughtering animals, particularly small animals such as pigs, and an anesthesia apparatus therefor.

``Prior Technology'' Traditionally, the slaughtering method in Japanese slaughterhouses was the electric shock method. In other words, in this method, a high voltage of around 220 volts is applied to the pig on the floor, and a blood exsanguination knife is inserted into the artery in the throat of the pig for about 12 seconds while the pig is repeatedly pulled with a shock to exsanguinate and collect blood. This is the work that will be carried out. However, this electric shock method
After 12 seconds, the pig convulses and becomes violent, which is dangerous for work, and considering that the slaughter method is currently being adopted on-rails, the fact that there is only 12 seconds between electrocution and exsanguination means that the pigs cannot convulse or act violently. The disadvantage is that the work is physically difficult.

Therefore, anesthesia devices and anesthesia methods using a carbon dioxide gas tank, as shown in FIG. 4, which are popular in Europe and other parts of the world, are attracting attention in Japan as well.

That is, this anesthesia device and anesthesia method
A carbon dioxide gas tank 3 provided with entrances and exits 1 and 2 for animals, a driving source (not shown) attached to this gas tank, and a carbon dioxide gas tank 3 that is rotated within the gas tank by this driving source and has a required interval. A cable member 5 to which a plurality of baskets 4 are attached, a plurality of guide members 6 that mesh with the cable member 5, and a guide member 6 provided near the inlet 2 of the gas tank 3 and installed in the gas tank 3. The guide member 6 consists of a support device 8 that temporarily holds the animal 7, and the guide member 6 includes upper and lower guide members 6a and 6b for raising, and upper and lower guide members 6 for raising.
It was composed of upper and lower guide members 6c and 6d for lowering, which were provided in parallel with the guide members a and 6b.

Therefore, in the anesthesia device and anesthesia method From there, it suddenly descends straight to the bottom of the gas tank 3, where it is the darkest. As a result, pigs have difficulty breathing, their capillaries break, and their livers, hearts, and other areas become congested.

However, if congestion occurs in the liver, heart, etc., it has the disadvantage that it does not meet the distribution needs of the Japanese meat market. However, in the Japanese meat market, the current situation is that slaughtered and butchered carcasses and internal organs are individually sold in the so-called raw state by each vendor. If there is congestion in the heart or other areas, it gives the impression to general traders and consumers that the area is deteriorating, and in some cases, the product has a large impact on the value of the product, such as not being able to sell. It is from.

``Object of the present invention'' In view of the conventional drawbacks, the present invention provides an anesthetic for slaughtering animals that can anesthetize animals without causing congestion in internal organs, and thus meets the needs of meat market distribution in Japan. There are methods and methods for obtaining anesthesia equipment.

"Means for Achieving the Present Invention" The present invention relates to an anesthetic method for slaughtering animals in which a plurality of baskets in which animals are fixedly supported in a carbon dioxide gas tank are rotated like a gondola to anesthetize the animal. The animal is lowered in stages by lowering the basket that supports the animal in a fixed manner through a plurality of other lowering guide members that are offset outwardly from the lowering guide member near the inlet of the gas tank. It is characterized by gradual anesthesia.

In the anesthesia apparatus Y having the above configuration, when carbon dioxide is supplied from the supply pipe (not shown) to the gas tank 10, the supplied gas has a higher specific gravity than air;
The gas gradually descends to the lower part of the gas tank 10 and is stored there.

Therefore, the deep pit 13a of the gas tank 10 has the highest concentration of gas, followed by the shallow pit 13b with an intermediate concentration, and the thinner part inside the lower case body 14b. .

Thus, when the drive motor 18 is driven, the power drive guide member 2 is
1 rotates, and the cable member 22 is guided by a plurality of guide members 25 as shown by arrows in FIG. 1 and rotates in one direction. When the cable member 22 rotates at a predetermined speed or intermittently, the positions of the baskets 23a to 23i also shift, thereby stirring the gas in the gas layer 10.

Next, the anesthetic method for slaughtering animals of the present invention shown in FIG. 2 will be explained. In the description of the embodiments of the present invention, each part of the anesthesia apparatus Y will be designated by the same reference numeral and redundant description will be omitted.

In the invention of the method shown in FIG. 2, this embodiment utilizes the anesthesia apparatus Y of the invention described above, and a plurality of baskets 23 that fixedly support animals h in a carbon dioxide gas tank 10 are arranged in a gondola shape. In an animal slaughter anesthesia method in which the animal is anesthetized by rotating, the basket 23 that fixedly supports the animal h is placed in the gas tank 1.
The animal h is gradually anesthetized by lowering the animal h in stages through a plurality of other descending guide members 25d to 25i provided offset outwardly from the descending guide member 25c near the entrance 12 of the animal h. It is characterized by That is, A shows a state in which a pig h driven into the inlet 12 of the gas tank 10 from the drive-in passage enters an arbitrary basket 23a located exactly at the inlet 12, and is once supported by the rotating plate 24d of the support device 24. This is just a push into the basket 23. B shows that when the cylinder 24b of the support device 24 is driven and the operating rod 24c is contracted, the other end of the rotating plate 24d that supports the pig h rotates downward, and the pig h located in the basket 23a is rotated downward. This is a step of supporting a pig basket, in which the pig falls down a little and is fixedly supported by both side plates of the basket 23a. C is the inlet 12 of the gas tank 10 shown in steps A and B.
The basket 23a, which was located at
The basket 2
This figure shows the first step of the stepwise descent in which the pig h fixed at 3a passes through the entrance 12 of the high case body 14a, passes through the low case body 14b, and moves into the shallow pit 13b. D indicates that the basket 23a is lowered from the shallower pit 13b by the lowering guide members 25g, 2.
5h and shows the latter step of the stepwise descent to the lowest part of the deep pit 13a. E shows a rising step in which the basket 23a supporting the completely anesthetized pig h at the lowest part of the gas tank 10 is lifted up to the outlet 11 of the gas tank 10 via the upper and lower lifting guide members 25a and 25b.

Then, the gas tank 1 was opened while supporting the anesthetized pig h.
The basket 23 pulled up to exit 0
As shown by the arrow in the ascending step E, pig h rotates in the hour hand direction so that it falls onto the receiving table 16 on its feet, and continues to circulate within the gas tank 10 following the cable member 22.

"Effects of the Present Invention" As is clear from the above description, the present invention has the following effects.

(1) A basket that fixedly supports an animal such as a pig is gradually moved through a plurality of other descending guide members that are offset outward from the descending guide member near the entrance of the gas tank. Since the animal is gradually anesthetized by being lowered to a lower temperature, the pig will not suddenly have difficulty breathing, and therefore the capillaries will not break and cause congestion in the liver, heart, etc. . In other words, the pig h supported in the basket can be anesthetized so as to gradually fall asleep.

(2) Since it is possible to obtain internal organs, etc. without congested state through slaughtering, the commercial value is not diminished. It meets the needs of the Japanese meat market, where commercial transactions are taking place.

(3) The method and device of the present invention are suitable for on-rail safe slaughter in abattoirs.

That is, as shown in FIG. 3, pigs h that have been anesthetized using the anesthesia device Y or the anesthesia method of the present invention are transported one after another to the receiving table 16 in the basket 23, so that the shaking operation located at the receiving table 16 is performed. The worker W1 ties the chain-like hook member 30 around one of the rear legs of the pig h and suspends the pig h as shown in the figure, and then another blood-letting or blood-collecting worker W2 attaches the blood-collecting knife 32 to which the blood-collecting hose 31 is connected. This can be done in a production line without any danger, such as by piercing the throat artery of a pig h to collect blood.
