探讨不同干燥温度和不同切片厚度条件下番木瓜的热风干燥特性。通过9种数学模型对番木瓜热风干燥试验数据进行拟合,结果表明:同大多数农产品干燥一样,番木瓜热风干燥主要为降速过程。不同干燥温度和物料厚度番木瓜热风干燥的水分有效扩散系数D_(eff)的变化范围分别是1.798 4×10~(-8) ~3.323 3×10~(-8),0.579 3× 10~(-8) ~2. 852 2× 10~(-8) m~2/s,由此可以看出番木瓜热风干燥的水分有效扩散系数随着干燥温度和物料厚度的增大而增大;Page模型是番木瓜热风干燥过程的最适模型,平均R~2值、SSE值、RMSE值和X~2值分别为0.998 1,0.003 3,0.012 4,0. 000 2。经回归分析,得到温度、厚度与有效水分扩...

In order to provide a theoretical basis for industrial application of hot air drying for papaya, the drying characteristics were studied in different hot air drying temperatures （60, 70, 80, 90 ℃ ） and in different slice thicknesses （4, 6, 8, 10mm）. By fitting the experimental data to nine mathematical models, the results showed that： as same as the most results of agricultural products drying test, hot air drying of papaya chips mainly occurs in the falling rate drying period. The effective moisture diffusion coefficient Deft respectivel...
