摘　　要：讨论单因素真空度以及物料厚度对水稻干燥速率的影响,并以温度、真空度、物料厚度为因素,采用二次正交旋转组合设计方法,建立水稻干燥速率的回归方程,进行双因素效应分析。采用贡献率法分析各因素的主次顺序,各因素对指标干燥速率影响的大小顺序为:物料厚度>干燥温度>真空度。运用Excel表,进行规划求解预测优方案。得出最优方案,在温度80℃,真空度为0.11 MPa,水稻薄层厚度为6 mm,可能的最大干燥速率为11.6%/h。The vacuum degree of the single factor as wen as the material thickness of the rice drying rate is discussed. Taking temperature, vacuum, material thickness as factors, using quadratic orthogonal rotation combination design method, the regression equation of rice drying rate is established, and the effects of two-factor are analyzed. Finally, the contribution rate method is often used to analyze the factors of the primary and secondary order. The order of the size of the impact of various factors on the indicators drying rate： material thickness〉drying temperature〉vacuum degree. Using Excel tables, solver forecast gifted program. Draw the optimal solution, at a temperature of 80 ℃, the degree of vacuum is 0.11 MPa, the rice thin layer has a thickness of 6 mm, and the maximum possible rate of drying is 11.6%/h.
