【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,通过对试验数据的分析,对不同风温下的干燥曲线进行模型比较,经拟合得出适合于丸粒化玉米种子的数学模型为page模型。该模型能较好地预测各干燥阶段的干燥速率及含湿量,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。更多还原

【Abstract】 Drying experiment of pelleted corn seed was conducted through three-factor and three-level orthogonal experimental design. Multiple element linear regression analysis program was employed to compare the model.Drying models for thin layer grain were made into linear model. Model comparisons of drying curves at different air temperatures were made. The results showed that the 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 and determine reasonable drying technology so that it can adjust and control the drying environment, and achieve higher efficiency and lower energy consumption.更多还原
