In the late 1990 s, with the deepening of reform and opening up, the live pig industry policy adjustment, the slaughtering once again set off a upsurge of construction of mechanized slaughterhouses.In the process of construction, some powerful big companies spend huge foreign exchange of a large number of imported equipment, the main reason is that pig slaughter processing equipment development in our country fails to keep pace with The Times, with the international advanced level in the distance.At present, the majority of small and medium-sized manufacturing enterprises mostly used by 60-70 s of the last century the development of the equipment, with the time progress, such as still use handheld appliances, photoelectric hemp appliances, swinging hot pig machine, three roller shaving machine, horizontal shaving machine, reciprocating splitting saws, etc.On the slaughter process, or manual assassination, pig blood to flow naturally, hot water immersion soup shave, clear water reserviors hair cutting residues, and in the process of slaughter knives and operator's hand without strict disinfection.These backward pig slaughter equipment and process greatly hampered the development of Chinese pig slaughtering.It can be said that at present our country pig slaughter and processing equipment and technology, and the country put forward the requirements of the implementation of the food safe projects, compared with foreign advanced equipment, domestic equipment in the performance, degree of automation, equipment reliability, meet the food hygiene requirements, reduce labor intensity, ensure the personal safety and other aspects have larger gap.
 

Slaughter processing largely determine the meat quality.In the whole process of environmental factors such as long distance transportation, slaughter processing fierce drive, hard blows, hemp, scalding water temperature has great influence to the pork quality, such as stun the scalding, steam and other technical improvements, greatly improved the health operation in the process of slaughtering and meat quality.
 

Also from the production of frozen meat carcass processing technology from heat, hot fresh meat, meat cutting and bare products to the cold fresh meat, cold segmentation and conversion of high value-added content of products.China is now in addition to the large-scale live-pig slaughtering enterprises realize the cooling processing division, cold-chain transport and cold chain store sales, market supply of large and medium-sized cities, and 90% of pork is without the cooling of the hot fresh meat, especially in rural areas and small towns, the traditional consumption habits is also keen to "night and morning pin".
 

Pig slaughtering equipment mechanization in China still needs to be strengthened
 

Look from the pig slaughtering conditions: mechanized slaughtering is better than a manual operation, mechanized slaughtering is an important measure to ensure the safety of pork quality.Practice has proved that mechanized, large-scale slaughter is one of the important conditions to ensure the safety of meat quality: one is slaughtering operation specifications, products of good quality;Second, the inspection items is complete, the product quality guaranteed;Three is advanced sewage disposal facilities and environmental protection guaranteed;Four is meat cooling process, improve the inner quality of meat;Five is the enterprise modernization management, guarantee the pork exports and foreign exchange.Slaughterhouse facility backwardness, slaughtered and manual mill type operation, sewage processing, low level of inspection and quarantine, animal protection condition is poor, difficult to guarantee product quality, disease prevention and treatment of difficult control, belong to the backward production capacity, give fall into disuse is necessity of social development.
 

Look from the slaughtering process operation, mechanized slaughtering enterprises adopted the most advanced slaughtering process.Mechanical slaughtering enterprises on a pig for slaughter, slaughter gastric disorder before water quiet, to reduce gastric contents, dilute the blood concentration, ensure good, bleeding and promote glycogen yuan decomposition, to generate the glucose and lactic acid distribution in the whole body, is advantageous to the meat after ripening, improve the quality of meat.At the same time, before slaughter in the shower, wash the dirt on the pig body, enhance the electrical conductivity, accelerate the blood circulation, easy to bleed, pig emotional stability, reduce stress reaction;On the stun, take hemp stun method, in particular, some modern machinery slaughtering enterprises have adopted the most advanced carbon dioxide anesthesia method, make the pig without danger, not frightened, reduced the repletion of decomposition, guarantee the freshness of meat;On might kill bloodletting, we adopt the most advanced bloodletting technology of hollow spine sword long drain blood, blood, meat storage;On scalding hair removal, the part of the mechanized slaughtering enterprises to adopt one of the world's most advanced hanging tunnel steam ironing washing method, to avoid the cross contamination between the get and improved the health situation of pig carcass and workshop.On the slaughter inspection, mechanized slaughtering enterprises inspection facilities, inspection personnel with high quality, inspection items, product quality is guaranteed.It is all effective measures to safeguard the quality of meat, is not than manual slaughter way.And manual slaughter lack advanced technological process, slaughter facilities humble, no rest, no shower before slaughter pigs, pig stress reaction, reduce the meat quality;The assassination of bleeding is not complete, meat is easy to corrupt, and shorten the shelf life;Water pollution is serious, hot pot (pool) get cross contamination, affect the quality of meat hygiene;Inspection facilities is not complete, the project is not complete, prone to leak phenomenon, to spread the disease, public health hazard.
