Description
STZ 7 and STZ 6 devices are suitable for the electrical stunning of animals.
From 2019, Regulation (EC) No 1099/2009 of 24 September 2009 concerning the protection of animals at the time of killing applies. According to the new regulations, every animal slaughtering plant should record the stunning parameters. The devices offered by our company have a factory-installed recorder of the stunning parameters, which measures the stunning parameters during slaughter and records them on an SDHC memory card placed in the recorder’s socket. The device with the recorder gives the possibility of remote assistance when setting the stunning parameters.
The operation of the STZ 7 is based on the principle of automatic measurement of the body resistance of the stunned animal. In the ready-to-run state, there is only a low safe measuring voltage of approx. 15 V at the open electrodes of the tongs. When the electrodes are pressed against the animal’s body, the resistance is measured and a stunning voltage of < 400 V is automatically applied, which is automatically switched off when the stunning process is completed (i.e. the electrodes are opened). Two electrodes are applied to the animal’s head, while a third electrode, using a pneumatic actuator, can be applied to the area of the heart, causing it to stop temporarily, as a result of which the blood stops flowing and the number of congested muscles decreases.
By stopping the heart with the third electrode, it is possible to significantly reduce the incidence of adverse factors affecting the quality of the meat.
