[0003] Before inspecting food, the inspected products need to be pre-processed, mainly by stirring and mixing. The existing stirring and mixing devices can solve the following problems: First, the staff manually mixes and stirs the food, which reduces the work efficiency and wastes unnecessary time; second, the heating and stirring must be switched continuously during stirring and mixing, which greatly increases the workload of the user when testing a large number of samples; third, it is not convenient to clean the inside of the tank after mixing the samples.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: when it is used, the stirring method is relatively single, and it is not convenient to move the mixed sample up and down for stirring; in the stirring and mixing process of the above scheme, the stirring range is relatively fixed, which can easily cause uneven mixing of materials in the bottom and upper areas of the mixing tank, and there are stirring dead corners or local accumulation and stratification of materials, and a longer stirring time is required to achieve the desired mixing degree, thereby reducing the adequacy and efficiency of material mixing. Summary of the invention
