Stunner

Meyn offers two types of stunners; a conventional stunner as well as a high frequency stunner. Both can be offered in a wide range of dimensions suitable for each specific situation.

In the conventional water bath stunner, the birds are hung in the shackles of the overhead conveyor by their feet and their heads pass through the water bath. Electrodes in the water bath and the shackle guide deliver the stunning shock as the bird’s head enters the water, effectively completing an electrical circuit.

The main advantage of high frequency stunning (over 50 or 60 Hz) is that the electric current at this frequency tends to run along the surface of the birds. This decreases the number of haemorrhages, largely reducing possible damage to the birds and thus benefiting meat quality.

Meyn’s stunners only require a minimum amount of water, keeping energy costs to an absolute minimum. They are easy to use, adjust and maintain forming an optimum start of the slaughtering process.

operations

The most conventional way of stunning is by means of a water bath. The birds, that hang in the shackles of the overhead conveyor by their feet, are lead through the bath, in which only their heads are immersed. In the water bath an electrode is placed which is connected to the control unit. The other electrode is formed by a stainless steel shackle guide, that touches the shackles which are placed above the bath. In that way an electric current is lead from the electrode in the water bath to the water, through the head and body of the bird to the feet, from the feet to the shackle and shackle guide.

The water bath can also be used for high frequency stunning. The advantage of high frequency stunning over 50 or 60 Hz is, that the electric current at high frequency tends to run along the surface of the birds. This decreases the number of haemorrhages, which benefits to meat quality. Frequencies used are 400 Hz, 1000 Hz and 2000 Hz. To obtain a sufficient stun, a period of 8 seconds is required.
