Embodiment 1

[0023] Embodiment one: the hair removal method of chicken.

[0024] 1. General situation 2 domestic chickens were slaughtered and depilated by hand.

[0025] 2. Boiled water for hair removal: 10 catties (about 5kg) of boiled water at 100°C.

[0026] 3. Cold water for hair removal Add about 250g of cold water (tap water) and 25g of salt to boiling water. Stir it with a wooden stick.

[0027] 4. Depilation Put 2 chicken feathers that have been slaughtered to death into the above boiled water, stir them, and then depilate by hand: first remove the skin on the claws and mouth, and then depilate (pluck) the whole body.

[0028] 5. Implementation results After about 30 minutes, the whole body of the 2 chickens was completely depilated, and the chicken body was intact. As for the control (pure boiled water hair removal), it takes nearly 1 hour, and the chicken body is scalded, peeling off in many places, and the economic benefit is reduced.

Embodiment 2

[0029] Embodiment two: the depilation method of duck.

[0030] 1. General situation 5 teal ducks were slaughtered.

[0031] 2. Wet the feathers with cold water. Use about 30 jin (15kg) of cold water (tap water) in the machine, put the duck into it, stir well, turn the feathers upside down to wet the duck's inner layer feathers, or manually turn them upside down Feathers can also be soaked in water. Then pick it up and drain the water naturally until it stops dripping.

[0032] 3. Boiling water hair removal Use 30 catties (15kg) of boiling water and add about 125g of vinegar. Stir it. Then put the duck body treated with cold water into the boiling water for manual depilation. After about 1 hour, all the depilation is clean. Hair removal can also be done in a machine.

[0033] 4. Implementation Results The results of depilation in this embodiment showed that all 5 ducks were depilated cleanly, and the skin was intact, and the elapsed time was 1 hour. The control (do not ...

Abstract

The invention discloses an unhairing method during killing poultry. Because the unhairing of the poultry is not easy, and the poultry are difficult to be unhaired cleared, toxic industrial rosin and asphalt are usually used in many places during unhairing, and the body health of people is seriously impacted. The unhairing method is characterized in that about 5 percent of cold water is added to boiling water used for unhairing, and a small quantity of table salt or table vinegar is also added, and then killed poultry is put in the boiling water for unhairing. According to the unhairing method, the poultry can be unhaired clean without using any toxic substances, the bodies and the skin of the poultry are complete, meat is safe without toxicity, and the cost is lower; and the unhairing method can be used for not only manual unhairing, but also mechanical operations and has good economic benefit and social benefit.

Description

technical field [0001] The invention relates to a depilation method for poultry slaughter, in particular to a method of adding cold water (normal temperature water) and the like in appropriate amounts to boiling water for depilation, saving time and cost, and improving product quality and benefit. Background technique [0002] Poultry depilation is an indispensable process when poultry is slaughtered. Whether hair removal is clean and whether the method is scientific is an important issue related to the quality of meat-eating products and people's health. [0003] It is well known that chicken feathers are easy to pluck but duck feathers are hard to remove. In order to effectively remove the feathers on poultry such as chickens and ducks, some slaughtering points and operating individuals use industrial rosin and asphalt for a long time to depilate poultry. Poultry meat depilated with industrial rosin and asphalt is equivalent to adding chronic poison, and frequent consump...
