GB/T 40469-2021 in English

Key points of cattle slaughter equipment standards

GB/T40469-2021, as an important technical standard in the field of livestock and poultry slaughtering and processing, puts forward systematic requirements for the design, manufacture, installation and acceptance of complete sets of cattle slaughtering equipment. This standard is applicable to industrial slaughterhouses with an annual slaughter capacity of more than 150 heads.

Equipment composition and configuration requirements

Key indicators: Safety factor of suspended conveyor rail ≥2, cumulative error of synchronous inspection and conveying ≤±150mm, and capacity of splitting equipment ≥150 heads/shift.

Key technologies for hygiene and safety

Safety control points: Emergency stop button response time <0.5s, insulation resistance ≥1MΩ, noise control ≤80dB(A).

Recommendations for the implementation of the standard

1. For newly built equipment, it is preferred to use a suspension conveyor
2. Regularly check the centering accuracy of the splitting equipment (vertebral offset ≤3mm)
3. Establish an air pressure log for the air conveying system (maintain 0.6-0.8MPa)

This standard introduces the quantitative indicator of cowhide breakage rate for the first time. It is recommended that enterprises control the breakage rate below 1.5% by optimizing the angle of the peeling tool.
