Six, the hardness of hacking is improper, easily breaks chicken superficial capillary vessels;
Seven, chicken needed certain quiescent time before entering electric numb machine, also needs certain hemofiltration time, guarantee that extravasated blood is discharged after bloodletting, but quiescent time and hemofiltration time are designed unreasonable.
Therefore, the present inventor improves for above-mentioned reason, and the tailor method of a set of reduction drumsticks extravasated blood rate, this case produces thus.
Summary of the invention
The object of the present invention is to provide a kind of method reducing drumsticks extravasated blood rate, to improve product hierarchy.
In order to reach above-mentioned purpose, solution of the present invention is:
Reduce a method for drumsticks extravasated blood rate, the sequence of operations of hair chicken from chicken house to slaughterhouse and processing procedure, increase following condition to corresponding steps:
The first, hanging Ji Tai increases black puggaree, blocks bright light rays;
The second, first wear emgloves when employee hangs chicken, then cotton gloves is worn over outside emgloves;
3rd, from Gua Jichu to electricity numb machine transport process in, increase massage plate, chicken is limited in the middle of massage plate, makes chicken in transport process be not easy to rock;
4th, ensure the quiescent time of 35-45s before entering electric numb machine;
5th, the set of frequency of electric numb machine is between 450-550Hz, and electric current is set between 300-350mA, and voltage is set between 10-15V, is best corona effects;
6th, during bloodletting, the pipe of bloodletting simultaneously, oesophagus and tracheae three are managed;
7th, ensure the hemofiltration time of 3min30s to 4min10s after bloodletting;
8th, after entering unhairing machine, the hardness of hacking is between 55-65HS.
Described 3rd, from Gua Jitai to electricity, the back of the corresponding chicken in the conveyer chain both sides of numb machine and shirtfront arrange massage plate.
Described 3rd, massage plate is the two boards be oppositely arranged in the both sides of connecting gear, and connecting gear moves between two pieces of massage plates, chicken is driven to pass through between two pieces of massage plates, chicken avoids rocking by massage plate restriction, and meanwhile, massage plate is massaged by chicken therebetween.
After adopting such scheme, the present invention is directed in the sequence of operations of mao chicken from chicken house to slaughterhouse and processing procedure, each can cause the step of drumsticks extravasated blood to improve, thus make chicken drumsticks extravasated blood rate drop to less than 30 percent by original 50 percent, substantially increase product hierarchy.
Detailed description of the invention
A kind of method reducing drumsticks extravasated blood rate that the present invention discloses, is specially for the improvement that the sequence of operations of hair chicken from chicken house to slaughterhouse and processing procedure are carried out, specifically increases process conditions in corresponding steps.
The first, use black puggaree at Gua Jitai, blocked bright light rays, reduce light to chicken stress.Stress be exactly the resistance that chicken produces when being subject to environmental stimuli, and then in chicken, produce some hormone, chicken meat quality can be caused to be deteriorated.
The second, first wear emgloves when employee hangs chicken, then be worn over outside emgloves by cotton gloves, minimizing extension chicken is the injury to chicken leg.
3rd, from Gua Jichu to electricity numb machine transport process in, increase massage plate on chicken back and two sides, shirtfront, be limited in by chicken in the middle of massage plate, make chicken in transport process be not easy to rock, minimizing stress.
Massage plate is specifically at the two boards that the both sides of connecting gear are oppositely arranged, the length of massage plate is not limit, can extend along connecting gear as much as possible, connecting gear is moved between two pieces of massage plates, connecting gear drives chicken more time ground to pass through between two pieces of massage plates, chicken avoids rocking by massage plate restriction, and meanwhile, massage plate is fully massaged by chicken therebetween.
4th, ensure the quiescent time of 35-45s before entering electric numb machine, minimizing stress.
5th, the set of frequency of electric numb machine is between 450-550Hz, and electric current is set between 300-350mA, and voltage is set between 10-15V, reduces chicken leg extravasated blood to the full extent, reaches best corona effects.
6th, during bloodletting, the pipe of bloodletting simultaneously, oesophagus and tracheae three are managed.Put the struggle that oesophagus and tracheae can increase chicken, thus accelerate the outflow of blood, accelerate the speed of bloodletting, bloodletting is more complete, than single blood vessel bloodletting put cleaner.
7th, ensure the hemofiltration time of 3min30s to 4min10s after bloodletting, extravasated blood is discharged as far as possible.So-called bloodletting refers to cuts this action of blood vessel, hemofiltration refers to the process that bloodletting relief blood oozes naturally, object is exactly discharge the blood in chicken body, reduce extravasated blood, the present invention optimizes the length of hemofiltration time, hemofiltration can reduce the residual of extravasated blood in chicken body fully, reduces extravasated blood rate, but the time passes and easily causes the putrid and deteriorated of chicken meat again for a long time.
