Description

A kind of depilating method when bird is slaughtered

Technical field

A kind of depilating method when the present invention relates to bird and slaughtering, especially a kind of in the boiling water of depilation, timely and appropriate discovery adds cold water (normal-temperature water) etc., and the cost of saving time improves the quality of products and the method for benefit.

Background technology

Bird depilation is bird indispensable operation when slaughtering.Whether lose hair or feathers clean, whether method science, concerning food meat product quality and the healthy major issue of people.

Chicken feather easily pulls out, and what the drake feather difficulty was removed is true well-known.In order effectively to remove the bird feather with it such as chicken and duck, what have slaughters a little and manages the individual, in the bird depilation, and the industrial rosin of prolonged and repeated use and pitch depilation.Taken off the bird food meat of hair by industrial rosin and pitch, be equivalent to add slow poison, often edible easily carcinogenic.Contain the materials such as resin acid, benzene granulation compound, lead in the industry rosin.Do not drain after wherein plumbous edible, child's intelligence etc. is had in various degree injury, suck manyly, injure larger.The pitch epilation is poisoned larger, eats for a long time the meat product of pitch processing, and the nervous system of meeting harm people makes people's neurasthenia, giddy, decrease of memory etc.

For fear of with overcome above-mentioned drawback, some places are actively sought the substitute of industrial rosin, in bird depilation, promote the use of rosin glyceride etc.Also have in boiling water, add some vinegar, make water slightly acid, the chicken and duck hair just easily pulls out clean.But existing method is also very incomplete.

Therefore, how to find the bird depilating method of more practicability and effectiveness, improve the food meat quality, guarantee the healthy of people, just seem very important.

Summary of the invention

The technical assignment of the technical problem to be solved in the present invention and proposition is the problem that exists when slaughtering depilation for present bird, and a kind of depilating method when providing a kind of bird to slaughter makes depilation easily, and speed is accelerated, and quality improves, and is good for health, increases economic benefit.

For this reason, the present invention adds about 5% cold water and adds a small amount of salt or vinegar in the boiling water of depilation, place boiling water to lose hair or feathers the bird of slaughtering again.

As preferably: the boiling water temperature is 98～100 ℃; After adding 5% cold water and a small amount of salt vinegar, stir with wooden stick immediately, water temperature is controlled at 85 ± 2 ℃.Aquatic bird when depilation, must first the fowl body be immersed in the cold water, through stirring hair down, make feather next to the skin fully moistening after, place again boiling water to lose hair or feathers.The amount of adding salt or vinegar is 0.5% of depilation minable water yield quality.

The inventive method, the bird depilating method with traditional has obvious difference:

1. the conventional method of bird depilation, temperature is approximately 98～100 ℃ when losing hair or feathers with boiling water; This patent when depilation, must in boiling water, add a certain proportion of cold water (approximately 5%), about 85 ℃ of temperature;

2. traditional depilating method, the depilation of chicken dove class is easier; But the palmipeds such as duck goose are difficult for drenching into water owing to pressing close to the feather of body, therefore depilation is difficult;

3. traditional depilating method usually uses industrial rosin and pitch, and is very harmful to human body; This patent method except putting into the cold water, also can be added a small amount of salt or vinegar (approximately 0.5%) in boiling water, harmless;

4. traditional depilating method is wasted time and energy, and the inventive method is both time saving and energy saving, and depilation is clean again.

The advantage of implementing patented method of the present invention is:

1. depilation is easy, time saving and energy saving, and is faster more than 30% than tradition depilation speed;

3. this patent method adds certain proportion cold water in boiling water, does not hinder bird skin and flesh, superior product quality, and economic benefit is high;

3. do not use the noxious material depilations such as industrial rosin and pitch; During depilation, in boiling water, add a small amount of salt or vinegar, nontoxic to human body.Cost is low, and is effective.

Boiling water is the main matter of bird depilation.In bird depilation boiling water, in certain method and ratio, adding cold water its objective is in order to make boiling water press close to bird body feather, both has been convenient to take off, again the injury of skin and superficial muscles not.Especially palmipeds, boiling water does not more advance nearly body, and after certain proportion and method were with cold water treatment, the boiling water depilation just became easier.

The specific embodiment

Be described further below in conjunction with the present invention.
