The stirring and mixing component 22 is disposed inside the sterilization heating component 21.

[0021] The sterilization heating assembly 21 includes: a pasteurization heater tank 211, a drive motor 215, a pull handle 212, a discharge pipe 214, a mixing rod 218, a cleaning pipe 217, a high-pressure washer 216, and a feed pipe 213. The lower end of the feed pipe 213 is installed on the upper end of the pasteurization heater tank 211, and the lower end of the pasteurization heater tank 211 is installed on the upper end of the support frame 1. The mixing rod 218 is rotatably installed inside the pasteurization heater tank 211. The upper end of the discharge pipe 214 is installed on the upper end of the pasteurization heater tank 211.

The output end of the drive motor 215 is installed on the upper end of the mixing rod 218.

[0022] The mixing assembly 22 includes: an electric hydraulic cylinder group 221, a lifting rod group 222, a scraper ring 225, an extension column 223, and a stirring blade group 224. The lower end of the stirring blade group 224 is rotatably mounted on the upper end of the extension column 223. The rear end of the extension column 223 is mounted on the inner wall of the scraper ring 225. The upper end of the scraper ring 225 is mounted on the output end of the lifting rod group 222.
