摘　　要：随着机采棉技术在新疆地区的应用,机采棉在中国所占比重增加,而机采棉由于回潮率高,需要在整个棉花加工过程中设置合理的子棉烘干工艺。分析了不同子棉回潮率下采用的子棉烘干最佳热风温度,并设计了一款补风阀来根据喂入子棉回潮率的不同调整补风程度。In recent years,with the application of the technology of han^esting cotton by cotton-picker in Xinjiang region,the machine-han^e sted c otton acc ount for the larger proportion in China.But due to the high moisture regain in mac hine-harvested cotton,it needs to set reasonable process of seed cotton drying during the whole cotton processing.The best hot air temperature during the process of seed cotton diying under the different seed cotton moisture regain M-as explored,and design a air valve M-hich can adjust the fill degree of the M-ind according to the different seed cotton moisture regain.

关 键 词：机采棉 回潮率 热风温度 补风阀
