摘要
在稻谷颗粒内部水分扩散模拟和应力计算的基础上，编制了水稻间歇干燥工艺的模拟程序，利用模拟程序分析了缓苏时间对干燥速度和稻谷颗粒内部应力分布的影响，并通过水稻干燥和缓苏的实验对模拟结果进行了验证，结果表明在干燥过程中加入缓苏段，可以提高下一个干燥段的干燥速度，并可降低谷粒内部的应力水平，减少稻谷的爆腰率。
n the basis of moisture diffusion and stress analysis within a rough rice kernel, an intermittent rough rice drying situation program was accomplished and it was used for analyzing the effect of tempering on the moisture removal and stresses profile in a grain kernel. The results were well agreed with the experimental data. It can be concluded that intermitting the drying processing with the tempering period can increase the moisture removal of the next period, decrease the stress level within the kernel and decrease the cracking ratio of rough rice.
