Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an anesthetic processing device for poultry, and more particularly to an anesthetic processing device for pre-treatment of poultry such as chickens for slaughter.

(Prior art) Conventionally, when slaughtering poultry such as chickens, the ankles of the poultry were hung upside down on a holder and transported using a transfer mechanism, and during the process, a cut was made on the neck and the poultry was slaughtered. After that, the hair is removed from the transfer mechanism, soaked in hot water, removed using a hair removal machine, washed in a washing water tank, and then soaked in a cooling water tank for cooling treatment. The current method of slaughtering chickens (for food) is mainly done manually, and the decapitated chickens become quite violent and are often exsanguinated as they fight with neighboring chickens. .

As a result, there are drawbacks such as bleeding in the chicken wings, deboning, or internal bleeding in the thighs due to the violent behavior during hanging, which significantly reduces the quality and commercial value of the meat.

In the past, research and development on slaughtering using electric shocks was conducted to solve this problem, but in this case, blood remained on the bamboo meat after it was slaughtered, resulting in a failure.

Therefore, recently research has been carried out on anesthesia treatment using carbon dioxide gas, and an anesthesia treatment device related to this was also developed in Japanese Patent Application Laid-Open No.
- Proposed as No. 107132.

This conventional device places a conveyor through the airtight door in a tank with airtight doors on both sides, and operates the conveyor with poultry cages placed inside the tank while the tank is filled with carbon dioxide gas. The patient is anesthetized for the time required from the entrance to the exit, and is put into a state of coma and asphyxia.

However, with the above-mentioned structure, when the bird cages pass through the entrance and exit of the tank due to the movement of the conveyor, carbon dioxide gas also flows out, resulting in a large amount of wasted carbon dioxide gas, which is economically uneconomical. It has a defect.

(Problems to be Solved by the Invention) In view of the above-mentioned conventional circumstances, the present invention has been devised to solve the above-mentioned problems. The purpose is to prevent the carbon dioxide gas being filled from flowing together and leaking out of the room.

(Means for Solving the Problems) The technical means taken by the present invention to solve the above problems is to place a cage containing poultry in a tunnel-like frame having a predetermined length. A conveying means is constructed by horizontally arranging a flat conveying means that accepts and moves from one side to the other, and fixing a partition plate to the conveying means or a flat conveying means separately arranged above the conveying means. By moving the frame, the cage storage chamber is successively divided by the peripheral side wall of the frame, the conveying means, and the partition plate, and the carbon dioxide injection means is placed near the inlet of the frame, and the used carbon dioxide gas injection means is placed near the outlet of the frame. The configuration includes a discharge means. The conveyance means installed inside the frame is a flat conveyance means such as a belt conveyor, so that the partition plate and the circumferential side wall of the frame form a closed housing chamber.

(Function) According to the above means, the conveying surface (belt) of the conveying means, the circumferential side wall of the frame body, and the partition plate form a hermetically sealed housing storage chamber. It is formed on the inlet side of the frame by the operation of , and moves to the outlet side while maintaining that state. Therefore, by storing the cages containing poultry in the cage storage chambers formed one after another on the entrance side of the frame, and filling the required amount of carbon dioxide gas with the injection means, the carbon dioxide gas can be filled. The chamber is moved as the transport means moves, and the poultry inside the cage is anesthetized in the time required to reach the exit of the frame, and the spent carbon dioxide gas is released from the cage when it leaves the frame. is emitted into the atmosphere.

It is constructed by winding a belt 15 around a pulley 14, and on the outer surface of the belt 15, partition plates 4 having the same width as the belt 15 are fixed upright at predetermined intervals in the circumferential direction, and at a substantially right angle. The partition plate 4
The length corresponds to the distance between the belt conveyors 2 and 3.

Furthermore, the partition plate 4 is fixed to the belt 15 of the belt conveyor 3 by abutting the mounting portion 4' of the partition plate 4, which is formed into a substantially L-shaped cross section, on the outer surface of the belt 15, and ) is the board 16
These are joined together and secured by tightening with bolts and nuts 17. Furthermore, notches 18 and 1 are provided on both left and right sides of the mounting portion 4' side of the partition plate 4.
The guide rails 19, 19' formed with 8' and fixed to the inner surface of the frame 1 are fitted into the belt 15 on the side where the partition plate 4 hangs below the belt 15. The belt 15 is prevented from loosening downward due to the weight of the partition plate 4, and the belt 15 is supported horizontally to prevent the partition plate 4 from tilting.

Furthermore, an edge frame material 20 made of urethane rubber or the like is attached to the outer peripheral edge of the partition plate 4, and this edge frame material 20 slides on the inner surface of the peripheral wall of the frame 1 and the outer surface of the belt conveyor 2 to maintain airtightness. It is designed to do so.

The carbon dioxide gas injection means 5, which is provided near the entrance of the frame body 1 in communication with the inside, has a supply pipe 21 installed on the front and rear walls of the frame body 1, and the carbon dioxide gas injected from this supply pipe is passed through a solenoid valve or the like 22. The injection time can be adjusted electrically, and the injection timing is also determined by separating the front and back of the housing 7 on the belt conveyor 2 with the partition plate 4 of the belt conveyor 3, and creating a closed housing storage chamber a. It is arranged to take place at the time of formation.

In order to supply carbon dioxide gas to the supply pipe 21 of the injection means 5, a liquefied carbon dioxide cylinder 23 and a vaporizer 2 are used.
