[0002] The invention also relates to a stirring method for mixing solid particles. Background Art

[0003] The finished polypropylene product must be mixed before sampling and analysis, and then the mixed sample is taken for measurement and analysis; whether it can be mixed during the sampling process is often a crucial step in the accuracy of sample analysis. The sample made without mixing is not representative. The analysis of polypropylene melt index often causes errors in the results due to the problem of mixing, and the product is in the form of fine particles, which makes mixing difficult. There is no suitable mixing container to reduce the error; during the sampling process, since the product is in the form of fine particles, it is very easy to spill, and recycling after sampling becomes a problem. Therefore, we propose a polypropylene stirring device that can fully stir and mix the sample to eliminate errors. The stirring device can complete the sampling and recycling work at one time.
