Benefits of technology

This approach allows for effective exsanguination with reduced equipment contamination, maintaining the integrity of the trachea and oesophagus connections and improving accessibility to the arteries, thereby enhancing the efficiency and cleanliness of the process.

Problems solved by technology

A problem which arises in particular when dead animals are being exsanguinated with the aid of the force of gravity is presented by the inaccessibility of the arteries in the neck when using the conventional methods of opening blood vessels with the aid of a rotating blade.
However, with the conventional means this is impossible without also cutting into or severing the oesophagus and / or the trachea.
Another problem in the prior art is the fact that opening a blood vessel in the neck of a slaughter animal which is hung by a (hind) leg immediately causes a large amount of blood to emerge from the neck, which blood contaminates the device used for opening to a considerable extent.

Embodiment Construction

[0071]FIG. 1a shows a stunned or dead fowl 2 which a hand 4 of a person (not shown in more detail) is carrying by its neck 5. The neck 5 of the fowl 2 is moved into a recess 8 of a hook 10, in the direction of the arrow 6, for hanging the fowl from the hook 10 by its head. The hook 10 may be stationary or may form part of a preferably endless conveyor, which is not shown in more detail, and moves along a path which is denoted by a dot-dashed line 12. The path 12 may be either curved or straight. The hook 10 can not only be conveyed along the path 12, but also can be tilted about an axis which runs parallel to the path 12.

[0072] As shown in FIG. 1b, the fowl 2 may also be moved into the recess 8 of the hook 10 with the aid of the hand 4 from a lying position on a surface 16 which extends between the dashed lines 14 illustrated. The surface 16 may be the base of a crate or a compartment of a crate, but may also, for example, be a belt of a moving belt conveyor.

Abstract

In a method and device for opening a blood vessel in the neck of a pre-positioned slaughter animal, a blood vessel is opened as a result of at least one cutting device being moved into the neck from one side of the neck towards the opposite side of the neck, the blood vessel being located in the path of the cutting device. The cutting device is an elongate blade which is moved in its longitudinal direction and is provided with a sharp, inclined front side. Before the blood vessel is opened, the distance between the trachea and the blood vessel is increased in an area of the opening.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This is a continuation application of PCT / NL00 / 00024 filed 14 Jan. 2000. FIELD OF THE INVENTION [0002] This invention relates to methods and devices for processing a slaughter animal, such as a fowl. [0003] This processing relates firstly to the mechanical opening of at least one blood vessel in the neck of a slaughter animal, in particular a fowl, comprising the steps of: positioning the neck of the slaughter animal; and opening the at least one blood vessel. BACKGROUND OF THE INVENTION [0004] When slaughtering animals, such as cattle, small livestock and poultry, it is customary, after the animal has been stunned or killed, to open one or more important blood vessels and to allow the blood to run out of the animal. The blood vessel which is to be opened is usually the carotid artery. In order to ensure that the blood runs out of the animal as fully as possible, it is moved into a position which is such that the sticking location is loc...
