| 摘 要： | 为探讨干燥条件对发芽糙米含水率变化的影响,应用薄层干燥试验台,研究干燥温度、表现风速以及相对湿度对发芽糙米含水率变化的影响。利用Matlab软件和Excel软件处理试验数据,建立了相关的薄层干燥数学模型。结果表明,干燥温度和表现风速对发芽糙米含水率变化影响显著,而相对湿度对其影响较小;依据试验数据建立的薄层干燥数学模型可以描述和预测发芽糙米干燥过程中水分的变化规律,其相关系数为0.9854。试验结果可以为研究发芽糙米干燥过程中水分变化规律提供理论依据。

| Abstract: | The influence of drying conditions,in terms of drying temperature,air velocity and relative humidity,on the change trends moisture content of germinated brown rice was studied in a thin-drying experimental table.The experimental data was analyzed with software of Matlab and Excel.A mathematical model was developed to describe the thin-layer drying of germinated brown rice.The results showed that drying temperature and air velocity have obviously influence on the moisture content of germinated brown,and the relative humidity of air has the least effect.The model could illustrate and predict the changing pattern of germinated brown rice moisture under drying conditions,with correlation of 0.9854.The results provided a theoretical basis for the predication of moisture content change of germinated brown rice. |
