Sea pelt processing technology

The main raw materials are jellyfish, alum and salt.
Equipment equipment cylinder or ground.
Method of production After the fish is harvested, the head should be cut with a knife in time. After the head and the skin were washed with seawater, the reddish moult was removed with a knife. The red cloth and the mucus on the back were scraped with a bamboo plate, washed with seawater, placed in a clean aquarium (pool), and then poured into a concentration. For 5% of alum water (a ratio of 250-300 grams per 50 kilograms of sea bream is completely water-soluble), stir well to prevent breakage of the skin and retting for about 10 hours. After removing the water from the early sea for half an hour, the weight of the skin after the water is weighed, and 7.5 to 9 kg of salt and ytterbium per 50 kg (5:0.2 to 0.25 for salt and yttrium) ]. First spread the salt mixture to the bottom of the pool. Then sprinkle a salt pan between each of the pelt skins. Scatter the thick skin. Place 3-4 sheets in one place. Marinate it all over the pool. A layer of salt is capped, and the seal is used for 5-7 days, after which it is drained for half an hour, and the brine and dirt on the pelt skin are cleaned with clean water, and the swill is then treated. The skin weight is 7-8 kg (5: 0.075 salt to rubidium ratio) per 50 kg of salt, and the jellyfish skin is evenly spread, and the mixture of salt and cesium is evenly spread. Every 7 to 8 sheets are used as a stack. In the middle, the top is covered with salt, pickled for 7 to 8 days, and the final luminosity is 220-240 Baume concentration. The jellyfish jellyfish after three days are rinsed with brine and wiped with cement blocks, etc. The erythema, after shaping, will be crushed on the wooden side of the cortex layer and drained, smashed 66 centimeters high, drained and boiled for 7 days, during which it should be flipped 1-2 times up and down, and the degree of dryness is reached by hand. brine For DDT, remove the grading, weigh it into plastic bags, fold it flat, spread salt evenly, pack it, and store it in a cool place.If it cannot be packaged in time, place it in 4% salt water. It can also be immersed in the simmering simmer, and the sable skin color is glossy, no red, toughness, no silt, loose flesh and no odor.
Process fishing → go to the head → dip → the first time → second time → three times → dry → packing → finished product.
