摘　　要：采用多元线性回归分析程序,将常见的谷物薄层干燥模型化为线性模型。在对丸粒化玉米种子进行三因素三水平干燥试验的基础上,通过试验数据的分析,对不同风温下的干燥曲线进行模型比较,经拟合得出适合丸粒化玉米种子的数学模型为Page模型。丸粒化玉米种子干燥特性不同于非丸粒化种子,丸粒化种子有其薄层干燥方程。该模型能较好地预测各干燥阶段的干燥速率及含水率,确定合理的干燥工艺以便调控干燥环境,达到高效低耗的目的。Drying experiment of pelleted corn seed was conducted through three-factor and three-level orthogonal experimental design. Multiple element linear regression analysis programs were employed to compare the models, and drying models for thin layer grain were made into linear models. Model comparisons of drying curves at different air temperatures have been done. The obtained mathematical model suitable for pelleted corn seed is Page model. The drying property of pelleted corn seed is quite different from that of non-pellet corn seed. The former has its own thin layer drying equation. This model can better estimate drying speed and moisture content at different drying stages, determine reasonable drying technology, so it can adjust and control the drying environment, and achieve higher efficiency with low energy consumption.
