通过对顺流式烘干工艺及干湿粮混合干燥工艺的研究，得出了各自的工艺参数及最佳组合。并就２种工艺进行了性能对比，得出了干湿粮混合干燥工艺较顺流式干燥工艺具有节能、提高效率、保证谷物品质等特点，论证了缓苏时间对干燥工艺的重要性 Through the study of the downstream drying process and the wet-dry food mixing and drying process, the respective process parameters and the optimal combination are obtained. And compared the performance of the two kinds of technology, the conclusion is drawn that the dry-wet food mixed drying technology has the characteristics of saving energy, improving the efficiency and ensuring the grain quality compared with the downstream drying technology, and demonstrates the importance of the slowing-down time on the drying technology
