摘要: 为减少玉米干燥中的能量损耗和干燥时间，以玉米的常规储存形态为研究对象，在SolidWorks建立玉米模型。以计算机流体力学仿真Fluent为工具，分析在玉米烘干过程中的水分流失情况。改变玉米的整体结构，对比相同温度和风速条件下玉米除芯状态和常规状态的干燥效果。结果显示，在相同工况下除芯玉米的颗粒含水量下降至（12%~14%），达到优良种子储藏标准。整体烘干效率提升约37.4%，保证了玉米种子的完整程度，发芽率更高。Abstract: To reduce energy consumption and drying time in corn drying, the conventional storage form of corn was taken as the research object. A corn model was established in SolidWorks, and computational fluid dynamics simulations were conducted using Fluent to analyze water loss during the drying process. By changing the overall structure of corn, the drying performance of corn in the coreless state and the conventional state were compared under the same temperature and wind speed conditions. The results show that under the same working conditions, the moisture content of coreless corn grains decreases to 12%~14%, meeting the standard for high-quality seed storage. The overall drying efficiency is improved by approximately 37.4%, while ensuring the integrity of corn seeds and achieving a higher germination rate.
