摘要:

為了揭示紅外輻射與對(duì)流聯(lián)合干燥機(jī)理以及干燥過程的熱質(zhì)傳遞特性，建立了聯(lián)合干燥過程的數(shù)學(xué)模型；數(shù)值模擬了稻谷干燥中的熱質(zhì)傳遞過程；根據(jù)數(shù)值模擬的干燥條件，搭建了紅外輻射與對(duì)流聯(lián)合干燥試驗(yàn)臺(tái)；通過紅外輻射與對(duì)流聯(lián)合干燥試驗(yàn)，研究了不同操作條件對(duì)干燥過程的影響。結(jié)果顯示數(shù)值模擬結(jié)果與試驗(yàn)數(shù)據(jù)吻合良好。

Abstract:

In order to reveal the mechanism of combined convective and infrared radiation in rice drying process and analyze heat and mass transfer characteristics, a mathematical model of combined convective and infrared radiation was established. The heat and mass transfer process in rice drying was simulated. According to the drying conditions in numerical simulation, the test rig of combined convective and infrared radiation was built up to analyze the influence of the drying process under the different operating conditions. The results showed that there was high relativity between the numerical model curves and the experimental curves.
