针对南疆地区霜后棉桃、僵瓣棉的回收利用现状，采用热风干燥方式，对棉桃物料进行不同温度下的热风干燥试验。结果表明：棉桃的干燥过程主要为降速干燥过程，但在干燥的预热初期出现了瞬时加速干燥段，未出现明显的恒速干燥段，干燥速率随干燥温度的提升快速升高。利用试验数据，与7种多孔介质物料的干燥数学模型进行拟合发现， Page模型拟合精度最高，并且模型参数简单，适合于干燥生产的实际应用；通过对模型中待定常数的求解，得到了棉桃热风干燥的数学模型。通过验证，该模型能很好地预测棉桃热风干燥时风温为80～100℃条件下的棉桃水分变化规律。

In view of the recycling and utilizing current situation of frosted bolls , deadlocked cotton in the southern Xin-jiang region of China , the cotton bolls under different temperature of hot-air drying experiment was carried out , the re-sults show that the drying process mainly for the falling rate drying process , but in the early dry preheating , the accelera-tion of the instantaneous drying period , does not appear obvious constant rate drying period , the drying rate concomitant the ascending rapid rise in the temperature of drying .Using the test data , and 7 kinds of porous medium drying mathe-matical model fitting found that page model high fitting precision , and model parameters is simple and suitable for the practical application of dry production;By solving the undetermined constants in the model , get the bolls of hot air drying mathematical model .It is can well predict that cotton bolls of moisture change rule under the condition of hot -air drying temperature from 80℃to 100℃.
