ABSTRACT: The root cause of corn kernel crushing is due to microscopic mechanical damage within the corn kernel during harvest and subsequent processing, and macroscopic crushing occurs if the damaged corn is subjected to sustained force. In this study, the powdered endosperm of corn kernels is used as an example to establish its microscopic discrete element model to study the generation and evolution of microscopic cracks. By taking SEM images of the powdered endosperm of corn kernels, the microscopic morphology and particle gradation of the powdered endosperm fraction of corn kernels were obtained, and starch existed in the powdered endosperm in the form of particles, with diameters mainly in the range of 2~22 μm........
Key Word: Corn powdery endosperm;discrete element model; PFC2D;starch granules; microstructure damage.
