How to slaughter white feather broiler chickens in slaughterhouse
After decades of development, the current white-feather broiler slaughtering and processing process is as follows:
Cage separation-hanging chicken-sedation-stunning-slaughter-bleeding-scalding-feather removal-head and claw cutting-open crop- cut open the chest -evisceration- Cleaning inside and out-carcass inspection-pre-cooling (bottom hanging)-segmentation-quick freezing - Repack - Freeze.
In all processing steps, pre-slaughter stunning, scalding and defeathering, carcasses body pre-cooling, broiler splitting, and product quick-freezing. The five processes have an important impact on the product quality, microbial safety, product output, and comprehensive selling price of the processing workshop.
Humane slaughter requires stunning of broiler chickens prior to slaughter. It is to make the broiler lose consciousness and achieve welfare slaughter. to achieve this purpose, many methods have been developed, the most commonly used and the simplest. The best method is electric stunning, water bath electric stunning, it is necessary to ensure that each chicken is electrocuted during the electric anesthesia
The current is controlled at 18-20mA, the time is controlled at 8-10 s, and the voltage is usually
Between 35 and 60V, and can use either alternating current or direct current.
Scalding and Feather removal
Feathers under natural conditions are very difficult to remove, broilers should be submerged in hot water to loosen feathers to denature the protein at the immobilized feather. specific combinations of time and temperature are the industry norm and they have different effects on depilation of broilers.
Broiler Scalding
The experimental results showed that broiler breed and scalding temperature chicken pH, brightness, redness, drip loss, cooking loss, etc. has a significant impact on the experimental optimization to get the best scalding process parameters: Hot temperature 58.4°C, scalding time 90 seconds.
Mechanical Feather Removal
In the future, the vertical and separate feather removal machine for broiler slaughtering equipment will become the hair removal machine market.
The mainstream of development direction. In the defeathering process, the combination of coarse feather removal and fine feather removal is required, and the coarse feather removal time is 25s, fine feather removal time is15s; the design of the cabinet angle is also very important. Needless to say, experiments have shown that about 155° is more appropriate, and the feather removal finger plate of the coarse feather removal machine Spacing 200 mm, fine hair removal machine feather removal finger disc spacing 150mm. The accuracy of process parameters is directly related to the degree and level of hair removal in the production process.
