Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] FIG. 1 shows, in side view, a first embodiment according to the present disclosure; and

[0018] FIG. 2 shows, in side view, the second embodiment according to the present disclosure.

[0019] FIG. 3 shows, in side view, the third embodiment according to the present disclosure.

DETAILED DESCRIPTION

[0020] FIG. 1 shows, in side view, a system 1 for treatment, stunning, slaughter and/or destruction of animals, such as cattle, livestock, poultry 2 and the like. The system 1 comprises at least one holder 3 configured to accommodate at least one animal 2. The system 1 further comprises an elongate tunnel 4 having an entrance 5 and an exit 6. Further, the system comprises a treatment supply 7 at least at or near the entrance 5 of the tunnel 4, which treatment supply is configured to insert a treatment substance into either or both of the tunnel 4 and the holder 3. Also, the system 1 comprises a transporter 8 extending through the tunnel 4 and configured to advance the at least one holder 3 through the tunnel 4 from the entrance towards the exit 6.

[0021] In this respect it is noted that the treatment supply 7 can be configured to provide a barrier of for instance nitrogen bubbles at the entrance 5 of tunnel 4. The holders 3 can have the form of crates. When crate-shaped holders 3 containing at least one animal 2 move through such a nitrogen bubble barrier, animals 2 in crate-shaped holders 3 are enveloped very locally in an essentially nitrogen based environment. Any alternative treatment substance can likewise be provided at the entrance 5 of the tunnel 4 by the treatment supply 7. The treatment supply 7 can be configured to insert nitrogen bubbles only into holders 3 or crates, instead of laying a barrier of such nitrogen bubbles at entrance 5 of tunnel 4.

[0022] In addition, not shown in FIG. 1, the system according to the present disclosure may comprise an additional treatment supply at least at or near the exit 6 of the tunnel 4. Such an additional treatment supply can provide a second barrier of nitrogen bubbles at the exit 6 of tunnel 4 in addition a similar barrier at the entrance 5 of tunnel 4. Thus, such an additional treatment supply can be configured to insert the treatment substance or an additional treatment substance into at least the tunnel. Reference is made here to an additional treatment substance, because the treatment substance to be administered at the exit 6 of the tunnel 4 may be different from the treatment substance to be administered at the entrance 5 of the tunnel 4.

[0023] According to the embodiment of FIG. 1, the treatment supply may comprise a supply of nitrogen bubbles forming the treatment substance. It is not to be excluded thereby, that other treatment substances can additionally or alternatively be provided at the entrance 5 of tunnel 4.

[0024] According to the embodiment of FIG. 1, a holder supply is oriented on the tunnel entrance. Such a holder supply is schematically designated with arrow A, and is defined herein to be oriented on the tunnel entrance 5 since crates or holders 3 are furnished in the direction of arrow A to said entrance 5 of tunnel 4. Likewise, according to the embodiment of FIG. 1, a holder discharge is oriented on the tunnel exit 6. Such a holder discharge is schematically designated with arrow B, and is defined herein to be oriented on the tunnel exit 6 since crates or holders 3 are discharged in the direction of arrow B from said exit 6 of tunnel 4.

[0025] In the embodiment of FIG. 1, the transporter 8 comprises or is associated with a casing configured to enclose the holder 3, during transport thereof over at least a portion of a distance between the entrance 5 and the exit 6 of the tunnel 4. Such a casing is formed by a transporter 9 opposite transporter 8, relative to the path along which holders 3 are advanced through the tunnel 4. Extending from the transporter 9 are boards 10 at variable distances there between, to adapt transporter 9 and the casings defined by boards 10 to the dimensions of the holders or crates 3. More in particular, boards 10 are arranged to join or abut against a frontal and against a rear surface of holders or crates 3, relative to the direction of movement of the holders or crates 3, indicated by the assembly of arrows A and B. Side surfaces of the holders or crates 3 are only a short distance from inner walls of the tunnel 4. Consequently, with this arrangement and configuration, treatment substances can be easily inserted into holders or crates 3, from above, through a top surface, to insert for instance nitrogen bubbles at treatment supply 7.

[0026] Further, in the embodiment of FIG. 1, the tunnel 4 can comprise a press 11 configured to immobilize the at least one animal in the holder 3. The press 11 itself is formed by a transporter 12, carrying protrusions 13, which can be manufactured from a relatively soft material, like rubber or plastic. Once a holder 3 or create has advanced past the transporter 9 that is equipped with boards 10 to define casings on, against or in holders 3 or crates, the holders 3 or crates arrive at the press 11. At such a time, the treatment substance will have begun to have an effect on the animals. To avoid panic or injury, protrusions 13 on transporter 12 of press 11 extend into the holders 3 or crates, as these holders 3 or crates move along the press over the transporter 8. By gently filling the space within the holders 3 or crates, using protrusions 13, flapping or kicking can effectively be avoided. The press 11 may extend over a considerable distance within the tunnel and along the inner length thereof, where preferably account is taken of the time needed for the animals to succumb. Likewise, the length of transporter 9, equipped with boards 10, canif sufficiently longalready suffice to allow the animals to succumb, without the features of the press 11, as indicated in FIG. 2, which is an embodiment of the present disclosure without the press.

[0027] Moreover, in FIG. 2, a larger dimensioned system 14 is shown as an alternative embodiment of the present disclosure, from which the press 11 of the embodiment in FIG. 1 is omitted. Further, the system 14 in FIG. 2 is designed for larger animals, in this case sheep 15.

[0028] These sheep are kept within the confines of accommodating crates or holders 3 over a longer distance defined by the transporter 9. When released from the transporter 9, the sheep are anticipated to have succumbed, obviating the need for press 11 or the like.

[0029] In FIG. 3 a rising tunnel system 18 is shown as a second alternative embodiment of the present disclosure, from which press 11 and transporter 9 are omitted and replaced by a rising tunnel 4. This system is particularly designed for the purpose of stunning poultry and water fowl for slaughter.

[0030] After the foregoing detailed description of embodiments of the present disclosure, it will be abundantly clear that a multitude of additional and/or alternative embodiments will force themselves upon the skilled person. By way of example, reference is made here to an additional or alternative embodiment, in which the system according to the present disclosure may further comprise the feature of at least one mobile frame, on which at least the tunnel with the treatment supply and the transporter are arranged. As a consequence of providing a mobile frame, the entire system becomes mobile and transportable, and can be transported to a location of use or other destination, where it can be set into operation, for instance for the destruction of sick or infected animals, or animals that are only suspected of being sick or infected, to avoid further spread of the disease. Thereby, any need is obviated for the animals to be transported to a system or a location of application of a method according to the present disclosure.

[0031] Tunnel 4 in either embodiment of FIG. 1 or FIG. 2 can comprise an exhaust 16, which may alternatively serve as means for supplying an additional barrier of the treatment substance or an additional treatment substance at the exit 6 of the tunnel 4. When intended to be operational as an exhaust, gases emanating from the tunnel can be captured thereby, for example to be recycled and/or reused.

[0032] As a potential embodiment of encasing holders 3, reference is made to transporter 9 that is equipped with boards 10. Additional boards on the sides of the crates can be provided, and even a top surface closing board over the top of the holders 3 or crates, in which the animals are accommodated. In fact, adding these components together will or can result in a configuration of a box turned upside down over the holder 3. Alternatively, the tunnel can simply be made to measure, which is to say small enough to accommodate just the width and height of a single holder 3. Thereby the need for encasing means can be obviated, in particular if barriers of nitrogen bubbles or other treatment substances at the entrance and exit of the tunnel are provided. It is again emphasized here, that embodiments of the present disclosure can relate to destruction or stunning for slaughter of animals, but also simply treatment for the benefit of these animals.
