[0002] In the production process of edible salt, main salt and other auxiliary salt need to be mixed. The mixed salt can be a physical mixture or a product generated by chemical reaction. In physical mixing, different salt crystals are mixed together to form mixed salt particles. For example, edible salt and sea salt are mixed together to form mixed salt. A mixing barrel is a mechanical device used for stirring and mixing materials and is widely used in various industries. For example, in the production process of edible salt processing and preparation,

[0003] When mixing salt, a mixing barrel is generally used. The traditional mixing method of the mixing barrel is to directly put the main salt and one or more kinds of auxiliary salt corresponding thereto. However, the main salt and the auxiliary salt are not very accurate in the input, and there is a certain error, which finally leads to too high or too low content of different auxiliary salt in the mixed salt, and the finished product salt obtained by mixing is far from the required product.
