[0003] During the slaughtering and processing of live pigs, most of the time, a canal-type scalding pool is used to scald the live pigs. Then, the live pigs are pulled by a controllable lifting rail and driven by a conveying mechanism to keep them in a suspended state in the scalding pool. After the scalding is completed, they are lifted to the front end of the depilatory device for unloading. Then, the live pigs are transported to the depilatory machine for depilation by manual handling or other external forces. Finally, the depilated pigs are transferred to a cleaning pool for cleaning. Therefore, the above-mentioned live pig slaughtering and processing is not suitable for continuous processing of live pig slaughtering, which greatly increases the labor intensity of the operator.
