Abstract

The invention relates to a method for depilating pigs, belonging to the field of animal husbandry and slaughtering, and is used for slaughtering and processing live pigs. A method of depilation of pigs, depilation with water scalding. The scalding water temperature is controlled at 56-58 ℃ in summer, and the scalding time is 4-6 minutes; in winter, it is 58-61 ℃, and the scalding time is 12-15 minutes. The scalding time and water temperature in spring and autumn are between winter and summer. After mechanical depilation, pour the heated food-grade rosin oil ester (adding a certain proportion of lard suet) onto the surface of the pig for re-hair removal (heating with a rosin heating pot). The oil ester is manually smashed and played back to the rosin heating pot for repeated heating. Using the method of the present invention for hair removal, the average hair removal rate of Huai pig commercial pigs is 98%. After knife trimming, the broken hair root in pig body skin was less than 2%. Pig skin is white and neat.

Description

technical field [0001] The invention relates to a pig hair removal method, which belongs to the field of animal husbandry and slaughtering and is used for pig slaughtering and processing. Background technique [0002] In recent years, with my country's increasing emphasis on the protection of local breed pig resources, coupled with the increasing demand for high-quality local pork, the development of local pork has made some progress, and the market demand for high-quality local pork is increasing. Local pig breeds generally have the characteristics of long growth cycle, thick skin, thick and strong hair, etc. There is the problem of difficult depilation and difficult depilation in slaughtering. The existing pig slaughtering process is mostly aimed at foreign breeds and hybrid commercial pigs with foreign breeds, and it is difficult to meet the requirements of local pig slaughtering and depilation in terms of scalding temperature and time and follow-up treatment after dehai...
