Technical Field

The invention belongs to the field of food processing, and particularly relates to a chicken processing device.

Background

Chicken duck goose is one of the poultry that eats often in daily life, along with the continuous improvement of standard of living, the chicken is the big meat of second only next to pork in the world, keep 3% consumption increase rate year, but traditional manual killing, scald and moult and have not satisfied the needs of society, the assembly line is slaughtered to the poultry has been widely used, it adopts stainless steel material preparation to slaughter the assembly line, it is high to have degree of automation, the stable performance, and easy operation is convenient, time saving and labor saving, safety and convenience, the life cycle is long, make slaughtering of poultry form batch production, the efficiency that the poultry was slaughtered is greatly improved, people's demand to the poultry meat products has been satisfied.

The iced fresh chicken refers to fresh chicken meat which is subjected to quarantine and pollution-free management procedures strictly and then is cooled rapidly, and the temperature of the same body in the month is reduced to be within the range of 0-4 ℃ within 2 hours. In recent years, with the continuous outbreak of avian influenza, the gradual replacement of hot fresh chicken by ice fresh chicken is a main trend of chicken consumption. Compared with fresh chicken, the frozen fresh chicken has the advantages of safety, sanitation, high nutritional value and the like, and is more and more popular with people. However, under current conditions, the chilled chicken is subject to microbial contamination from the production, transportation, sale, storage, etc. processes, and the chicken is highly perishable. The shelf life of related products in the market is generally short, which greatly restricts the development of the market of the chilled poultry meat. In recent years, domestic reports on fresh-keeping technologies of chilled chickens are increasing.

Scientific research shows that the temperature of the cold fresh meat is rapidly reduced to 0-4 ℃ after the livestock and poultry are slaughtered, the propagation of pathogenic bacteria of human and livestock suffering from avian influenza, streptococcus and the like and the activity of autolytic enzyme are inhibited, and the decomposition of protein and amino acid is inhibited, so that the loss of meat and nutrient substances is reduced. Therefore, the cold fresh meat is safer and more sanitary, has good quality, high nutritive value and more delicious taste than the hot fresh meat.

The frozen fresh meat has incomparable advantages compared with hot fresh meat and frozen meat, meets the expectations of modern consumption on the sanitary safety, tenderness, juiciness and taste of meat, and accounts for 10-15% of the meat consumed by everyone in the year at present. However, the frozen fresh meat faces the bottlenecks of juice loss, surface browning and short shelf life, the existing frozen chicken processing line device and the existing frozen chicken processing method cannot reduce the bacterial breeding in the low-temperature environment, and the problems of juice loss and surface browning of the processed frozen fresh meat face, the pollution is serious due to incomplete cleaning, and the shelf life of the frozen fresh meat is reduced.
