摘　　要：采用具有微波吸收功率精准测定功能的微波干燥试验装置,进行了硫酸铜的干燥工艺特性试验研究。结果表明采用该微波干燥工艺加工硫酸铜,可将含量在95%左右的CuSO_4·5H_2O,干燥至96%到98.62%,即可将二级硫酸铜干燥为一级硫酸铜。该工艺具有干燥时间短,产品质量均匀,能耗低和实现微风干燥等优势。Abstract： In order to determine the characteristics drying, a microwave drying test device with absorbed of copper sulfate pentahydrate during microwave microwave power measuring functions was used to carry out the microwave drying of molybdenum powder. The results show that the technology of rectangular pulse heating microwave drying can improve Copper Sulfate Pentahydrate from 95% to 96%～98.62%,which means it can raise the second level Copper Sulfate Pentahydrate to the first level. This microwave drying process has the characteristics such as lower power consumption, short drying time,lower lost and dust free.
