Connect supply semi-automatic and fully automatic evisceration line.
The semi-automatic evisceration line is good for the customer where the salary of workers

is low.

By this way, the viscera is not easy to be demaged ,Good for developing areas. The steps are as follow:
Neck slitting and foot removal
A vertical incision is made in the skin on the dorsal surface of the neck to assist in the removal

of the crop,oesophagus and trachea at a later stage. The feet are removed automatically by a

cutter on the line or by manually operated scissors. The birds drop on to a conveyor that transfers them through a

narrow opening from the "dirty" section of the slaughterhouse into the "clean" section. Semi-Automatic Evisceration
The birds are hung up again by the hocks on to the shackles of the eviceration line. The line runs above a

water trough or a mechanical conveyor ,which carrries away waste materials. Various operations are

carried out on this line:
Head removal:
The heads are generally removed mechanically by tracction of a head puller. After proper positioning the

head and trachea puller breaks the spine at its weakest point after which the head,crop , oesophagus and

trachea are stretched out
Venting:
Scissors cut a round vent in order to remove the intestines from the carcass . Great care is needed in this

important operation as faecal contanmination of the carcass,edible offals and operators' hands has to be

avoided.

Drawing:
All of the viscera are drawn out of the body cavity,leaving them hanging from the carcass ready for

inspection. The drawing is done either by hand or by operators using eviscerating forks or by automatic

eviscerating machines.
At this point inspectors examine the viscera ,the body cavity and the carcass generally. Good lighting,

properly directed into the body cavity I is essential.
Some machines separate the viscera pack immediately from the carcass after drawing. The viscera

packs can then be examined more quickly under more hygienic conditions.

Removal of offals:
The edible offals, i.e. the heart, liver and gizzard are removed for further cleaning and washing.The intestines,

proventriculus and lungs are discarded into the wter trough or medchanical conveyor.On some lines a

suction tube is then introduced into the body cavity to remove any contamination or portions of lungs remaining.
When the viscera pack is already separated automatically , all operations on the pack can also be carried

automatically. The results in a highter heart and liver yield and better microbiological quality.
An inspectior or a quality control officer then examines the carcass generally, especially the body cavity.
Neck removal:
The necks are removed by cutting through the vertebrae between the shoulders using automatic or manual scissors.

The necks are classified as part of the edible offal or giblets.
Line washing
Before going into the washing and cooling tanks the birds are spray washed to remove blood and extraneous matter.
Polyphosphate injection:
When polyphosphates are used, they are injected under pressure by guns with two hollow perforated needles.

The solution is injected into the breast and sometimes also into the leg muscles.Up to 5% of the body weight of this

permitted additive solution may be injected.
