First, slaughter and skinning 1. Slaughter: In order to keep the skin intact, economical and simple, and quickly die, terrestrial fur animals can be processed into tube skins or socks skins according to product specification requirements. The main methods of death are: folding neck method, electric shock method, suffocation method, post-killing method, clubbing method, drug lethal method and heart injection air method. Collapsing neck method: After catching the animal, place it on a firm and smooth platform, press its shoulder and neck with your left hand, hold your lower jaw with your right hand, and tilt your head back upwards. When you reach the limit, quickly press your head forward and downward. Promote, can send out the dislocation sound of cervical and occipital bone, show that the cervical spine has dislocated. At this point, the animal has become paralyzed, limbs straight, and constantly shaking. This method is easy to operate, requires no equipment, and is executed quickly. This method is suitable for mink and other small fur animals. After death, the body should be placed in a clean, cool place and should not be stacked. If not peeled immediately, the body should be placed at a temperature of 1 to 10°C. Otherwise, under the condition of room temperature, the hair bundles are easily damaged due to the action of enzymes, and the temperature is too low to cause skinning difficulties. 2. Peeling: Peeling is best performed when the body is still warm, and it is difficult to freeze and peel. According to product specifications, skin animal skin stripping methods include: cylinder type (fox, raccoon, otters, purpuras, squirrels, beavers and other animals), socks and flake skin and other methods. Cylindrical type: fixed a hind limb, from the palm of another hind limb under the knife, along the inner long hair line of the hind limb straight to the anus to pick, at 1 cm from the side of the anus, folded to the anus and the tail opening convergence. On the other side of the hind leg, the same method was used to pick the back edge of the anus, and then the two limbs of the hind legs were turned and the triangular skin was removed. Operation, must be strictly according to the long hair line, or affect the skin length and appearance; in 1 cm from the left and right side of the anus to the posterior edge of the anus to pick open, the blade should be close to the skin, to prevent cutting the anal gland. First remove the skin and coccyx at the middle of the tail with a knife, and then withdraw the coccyx with your hand or forceps. After peeling and provoking, use sawdust to wash the blood on the knife edge. When peeling, first insert the finger between the skin and muscle of the hind limb, peel the skin and muscle of the whole hind limb, insert a finger into the back of the toe at the metacarpal bone, peel the skin, expose the last metatarsal bone, cut the phalanx with scissors, and make the hind limb skin. Completely normal claws. After the two hind legs are peeled off, a hind leg is fixed on the worktable, the skin is grasped with both hands, and the skin is pulled down to make it into a cylinder. Peel the abdomen when peeling the pimple, and cut the penis to avoid tearing the abdomen. When peeling the head, the left hand grasps the skin, and the right hand uses the knife at the root of the ear and the base of the eyelid against the periosteum to carefully cut the subcutaneous tissue that connects the skin to the periosteum, so that the ears, eyelids, nose and tentacles remain intact. Second, processing methods: 1. Scraping oil: According to the operating specifications, otherwise it is easy to cause penetrating, scraping, knife holes, etc., directly affect the value of fur. Oil can be divided into two methods: manual operation and mechanical scraping. Cylindrical skin oil: a smooth, flat oil stick should be put into the cylinder, the skin should be tightened, and the skin should not be wrinkled. From the tail to the head, scrape and wash with sawdust. When the head muscles and connective tissue are more difficult to scrape, they can be trimmed with scissors. 2. Scrub: The fur after shaving must be washed with hard sawdust or crushed corn cob of small grain size to remove dirt and dirt from the attached skin plate and quilt, making the pile more bright, clean and beautiful. Eye-catching. Washing can be divided into manual and mechanical methods. The sequence of washing should be started from the back of the skin and it is strictly forbidden to use wheat bran or resin-based skin wash. Hand-washing is suitable for farmers with few hides and no equipment. The machine wash skin first wash plate, can turn the skin plate into the skin plate outward, mix with clean sawdust, in order to dry. After taking it out, place it in a rotating basket and turn it for 3 minutes. Attach it to the sawdust. Then, the hair was washed again, and the skin was overturned and rolled in the drum for 5 minutes to remove the dirt and slicks on the hair. The hair was presented with its original appearance. Then put it in the cage and roll it for 3 minutes to remove the sawdust remaining in the quilt. 3. The upper jaw: Before the upper jaw, the absorbent paper can be cut into oblique strips and wrapped around the jaws. Then put on the fur, adjust the legs of the two forelimbs to make it flush with the abdominal hair. Turn the jaws, pull the head, and adjust the ears, eyelids, nose and other parts. The back midline and tail are placed on the centerline of the epiphyseal plate. When the fresh skin is stretched properly to extend it to a certain scale of the epiphyseal plate, it is fixed with a leather nail or a push pin. The skin should be pulled horizontally to make the fur 1/3 to 2/3 shorter than the original tail and fixed with fine lead wire. Then turn the sacral plate, widen the legs of both hind legs to make it flush with the edges of the ventral surface and the hip skin, and press the thin barbed wire to fix it. 4. Drying: Use a once-upon, temperature-controlled air drying method. The squeezing tip of the squeezing tip of the snorkel is placed on the air cylinder. The air passes through the special structure on the sampan plate and is evenly blown between the slasher and the liner. After a certain period of time, the cover can be obtained. Evenly dry. The skin is usually air-dried for 24 hours at 20°C to 25°C. The male skin is slightly thicker and the drying time should be longer. When it is naturally dry at room temperature, the skin must first be turned outwards. When the skin is dry 7-8 percent, it is turned and the hair is dried outward. No matter what kind of drying method is used, the temperature should be controlled at 20 °C ~ 25 °C. It is forbidden to bake at a high temperature to prevent the occurrence of bending of the needle hair, coke board skin and tarpaulin. 5. Packing and Storage: After drying the raw material, remove the cheeks, comb and rub. According to the requirements of different skins and different types of goods, they are sorted and packaged and sealed into storage. It is required that the temperature in the storage chamber be maintained at 5°C to 25°C and the relative humidity be 60% to 65%.
