摘要: 【目的】研究不同制干工艺对新疆主要制干葡萄品种无核白和无核白鸡葡萄干燥特性的影响,为新疆葡萄干燥工艺的改进提供理论依据。【方法】对晾干和晒干干燥过程中的水分变化规律进行数学分析,研究葡萄的干燥特性。【结果】晒干工艺葡萄的失水速率高于夜间,葡萄干燥过程中白昼失水速率是夜间的2.00~6.14倍。干燥初期晒干工艺条件下无核白鸡心葡萄失水速率是晾干的1.21~3.12倍。葡萄果实干燥模型宜选用Page模型,晒干工艺条件下葡萄果实的有效水分扩散系数分别是晾干工艺的3.14和3.18倍;无核白鸡心葡萄果实的有效水分扩散系数高于无核白葡萄,晒干条件下无核白鸡心葡萄和无核白有效水分扩散系数分别为6.023 16×10-8 和2.615 45×10-8 m2/h;晾干条件下2种葡萄果实的有效水分扩散系数分别为1.892 12×10-8 和8.308 75×10-9 m2/h。【结论】2种干燥工艺下,白昼的干燥速率显著高于夜间,得到了不同干燥工艺和不同葡萄品种的有效水分扩散系数。

Abstract: 【Objective】 To provide theoretical basis for improving the drying techniques of Xinjiang grapes: Thomson Seedless and Centennial Seedless, the effects of different drying techniques on the drying characteristics were studied in this paper.【Methods】 The variation of moisture in drying and drying process was analyzed mathematically to study the drying characteristics of grapes.【Results】 In the process of grape drying, the dehydrating rate during the day was 2.00-6.14 times higher than that of the night. In the early stage of the drying process, the dehydrating rate of grape in the mode of drying in the sun was 1.21-3.12 times as high as with shade-air drying. The effective water diffusivity of the sun-dried grape berry of the two varieties of grapes was 3.14 and 3.18 times higher than that of the shade-air-dried one. The effective water diffusivity of Centennial Seedless was higher than that of Thompson Seedless. The effective water diffusivity of Centennial Seedless and Thompson Seedless under sun-drying was 6.023,16×10-8 m2/h, 2.615,45×10-8 m2/h, and in shade-air-drying was 8.308,75×10-9 m2/h,1.892,12×10-8 m2/h.;【Conclusion】 The drying rate in daylight was significantly higher than that during night under sun drying and shade-air drying. The effective water diffusivity of different drying processes and different drying grape varieties was obtained. The study results can provide a basis for the improvement of shade-air drying rooms in Xinjiang.
