A multi-function experimental platform for the research on the mechanical-physical properties of grain granular materials is developed. In combination with the reform on the experimental teaching in food machinery, the integration of scientific research and teaching is studied, and the content of courses and the teaching methods are reformed. Research innovation experiment on compress, shearing and seepage of grain granular materials is developed based on the experimental platform. With experimental course teaching, college students extracurricular research and their graduation thesis, innovat...
