Process for processing fishes cleanly in high quality

Abstract

The invention belongs to the technical field of fish processing, and particularly relates to a process for processing fishes cleanly, which comprises the following steps of: stunning the fishes instantly, namely stunning live fishes by using rated voltage so as to allow the fishes to have heartbeat but lose memory or stunning the live fishes in a closed bag by using carbon dioxide; cutting fish gills off, namely allowing a knife to extend into the fish gills from water outlet edges of the fish gills on sides of fish cheeks to cut the fish gills on both sides off; performing bloodletting, namely hanging the fishes of which the fish gills are cut off in a mode of allowing fishtails to be upward and fish heads to be downward for bloodletting, so that fish blood flows out of fish mouths until the fish blood is discharged completely from fish gill cavities; washing, namely washing blood in fish mouth cavities cleanly by using pressurized water conveyed from the fish mouths, and washing dirt and mucus on surfaces of fish bodies cleanly; and drying, namely drying the water on the surfaces of the fish bodies by using a water absorption material. The process has the advantages that the fishes are stunned instantly, so the slaughter effect is good; the bloodletting is complete in a mode of cutting the fish gills off, so fish flesh is not polluted; and the fish bodies are hung upside down, the bloodletting is complete, and time and labor are saved, so the process is suitable for processing various fishes, particularly globefishes cleanly.

Description

technical field [0001] The invention belongs to the technical field of fish processing, in particular to a high-quality clean processing technology for fish, and is especially suitable for the clean processing technology of puffer fish. Background technique [0002] As we all know, puffer fish, scientific name pufferfish, ancient name lungfish, commonly known as air drum fish, air bubble fish, blow belly fish, chicken bubble fish, Qinglangjun, stickleback fish, etc. Fish belonging to the three-toothed, four-toothed and boxfish families. There are more than 100 species of puffer fish distributed all over the world. Once a puffer fish is threatened, it will swallow water or air to inflate its body into a spiny ball, which is difficult for predators to bite. The internal organs of many species of puffer fish contain a deadly neurotoxin. Someone measured the toxicity of tetrodotoxin TTX. Its toxicity is equivalent to 1250 times that of the highly toxic drug sodium cyanide, a...

Problems solved by technology

[0004] At present, when people are slaughtering fish, they generally first throw the fish to be killed to death before slaughtering, or directly use a knife to cut off the head of the fish to be slaughtered, or cut off the vertebrae of the head to slaughter, or directly open or first kill the fish. Process the puffer fish after cleaning and freezing. If the puffer fish is also slaughtered in this way, the fish to be slaughtered or the fish that have not been slaughtered at the time will see the same kind being slaughtered. After being frightened, the body will secrete A kind of unfavorable substance and a substance with high nutritional value in the consumption of fish body, this unfavorable substance will have adverse effects on the body after being eaten by people, and then the fish is thrown to death or bloodletting after killing, the fish blood will not be completely Put it clean, and you can’t get high-quality fish, especially the blood of puffer fish contains high toxins. If the blood of fish that has not been cleaned clean penetrates into the fish meat, it will cause life danger to the human body. This problem is now the processing of all puffer fish No one has a better solution

[0005] For example: the technologies disclosed in CN101283697A, CN101283698A, and CN1582679A all clean the puffer fish first, and then directly use a knife to slaughter and bloodlet the fish to be slaughtered and perform subsequent processing. Direct slaughter will make the fish to be slaughtered or the fish that have not been slaughtered at that time After seeing the same kind being slaughtered, because of being frightened, the puffer fish will secrete an unfavorable substance (blood acid) and consume substances with high nutritional value (hormones) in the fish; these substances are harmful to the human body, affect the flavor, reduce the The product quality is improved; the disclosed technology of CN101301092A is to first clean the puffer fish, and then process the puffer fish after freezing. Substances with high nutritional value; most of the above-mentioned disclosed technologies are to cut off the fish mouth, so that the processed fish loses its integrity, and it is easy to be infected with bacteria so that the raw materials will deteriorate
