Description

Chicken processing system

Technical Field

The invention relates to the technical field of chicken processing equipment, in particular to a chicken processing system capable of effectively cleaning chicken ketone bodies and achieving effective bacteriostasis.

Background

The frozen meat refers to the meat which is slaughtered and frozen to form frozen meat, and the storage time of the frozen meat can be effectively prolonged.

The chicken meat is one of the main edible poultry meat in the world, is tender in meat quality, delicious in taste and suitable for various cooking methods, contains rich vitamin C, vitamin E and the like, contains higher protein and higher nutrient components, and has the functions of nourishing and tonifying the body.

The frozen chicken is formed by slaughtering a live chicken, then carrying out processes of bloodletting, defeathering, cutting, freezing and the like, wherein different parts of the chicken need to be cut in a classified manner during cutting, and then the chicken needs to be frozen in a classified manner so as to meet different requirements of different customers.

In the chicken processing process, the chicken carcass is easily polluted by microorganisms due to the influence of viscera rupture, cross contamination and the like, and the pollution degree is very high. The initial bacteria carrying amount of the slaughtered product is high, so that the product is not easy to store, is easy to rot, and the safety of the product is reduced. The initial bacteria carrying amount of the chicken carcass is high, the shelf life of the product is short, and the chicken carcass becomes an important problem restricting the development of the iced fresh chicken industry. In the existing chicken processing system, the cleaning mode of chicken ketone bodies is generally realized by hanging chicken on a conveying chain, sequentially passing through high-pressure water and cleaning by utilizing high-pressure water flow, and for the processing for ensuring the integrity of the chicken ketone bodies, the process of removing internal organs does not cut live chicken in a large range, but takes out the internal organs by opening a small opening; therefore, the cleaning method of directly hanging chicken on a conveying chain by using high-pressure water often only can clean the outer surface of the chicken ketone body but cannot effectively clean the inner cavity of the chicken ketone body, and in addition, the cleaning efficiency is influenced because fluff or horny layer attached to the surface of the ketone body cannot be cleaned by only using high-pressure water flow.

According to the results in table 2, after the chicken ketone bodies are soaked and brushed by adopting different soaking solutions, the same inner cavity spray washing and outer surface spray washing are adopted, the bacteria carrying capacity and the villus residual rate are influenced, after the chicken ketone bodies are soaked and brushed by adopting the soaking solution in the embodiment 4, the subsequent inner cavity spray washing and outer surface spray washing are carried out, the bacteria carrying capacity and the villus residual rate are optimal, if the soaking solution is replaced by purified water, the bacteria carrying capacity and the villus residual rate are maximal, when brine is used as the soaking solution, the bacteria carrying capacity is minimal, the villus residual rate is high, when fruit vinegar is used as the soaking solution, the bacteria carrying capacity is high relative to the brine, but the villus residual rate is high, probably because pores on the surfaces of the chicken ketone bodies are favorably opened at a proper temperature, the villus is favorably removed, the flavor of chicken is not influenced by the fruit vinegar at a proper concentration, and the brine is favorably sterilized at a proper bacteriostatic temperature, when the brine and the fruit vinegar are combined with each other in a proper ratio, the surface villus is removed, the sterilizing effect is further enhanced, and the bacteria carrying capacity is greatly reduced.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
