In addition, the setting of the semi-height protective plates 11 further enhances the operating safety and hygiene standards of the equipment.

[0049] Working principle:

[0050] During use, poultry passes through each processing station in sequence via the conveyor belt 1. First, the poultry is conveyed to the position of the electrostunning device 3. The first cylinder 31 in the electrostunning device 3 pushes the first arc-shaped block 33 forward. The electrodes on the first arc-shaped block 33 are connected to the power supply via the cable 34. When the head of the poultry touches the electrodes, the first spring telescopic rod 6 ensures good contact between the electrodes and the head of the poultry, completing the electrostunning process. Subsequently, the poultry is conveyed to the clamping device 5. The second cylinder 51 in the clamping device 5 pushes the second arc-shaped block 52 to clamp the neck of the poultry, and the chicken neck positioning groove 55 ensures that the head of the poultry is precisely fixed.

[0051] Then, the poultry enters the area of the slaughtering device 4. The third cylinder 41 pushes the third arc-shaped block 42 forward, and the blades on the blade column 46 quickly penetrate the heart or carotid artery of the poultry, completing the bloodletting process. The slaughtered poultry enters the blood receiving trough 17 along with the conveyor belt 1, and the blood is collected. After that, the poultry passes through the poultry scalding pool 18, the dehairing machine 19, and the spiral precooling machine 20 in sequence, completing the scalding, dehairing, and precooling processes.

[0052] Throughout the process, the first protective box body 9 and the second protective box body 16 play an isolating role, preventing blood from contaminating the electrostunning device 3 and the slaughtering device 4. Meanwhile, the water collecting trough 15 collects the liquids generated during the processing, keeping the equipment clean. Through such a work process, the automated production of poultry from electrostunning to chilled fresh processing is realized.
