微波干燥蚕茧的工艺研究

采用不同质量比功率、铺放厚度和分段干燥等方式,对微波干燥蚕茧工艺进行了研究。结果表明:质量比功率对微波干燥影响较大,而铺放厚度对微波干燥影响较小;质量比功率大于8W/g时,出现茧内蛹体破裂,会影响蚕茧干燥质量;采用分段干燥有利于干燥过程的进行;微波干燥可提高蚕茧干燥效率和茧丝洁净度。

The Study on Microwave Drying Technique of Silkworm Cocoons

Through the experiment of several factors influencing on the microwave desiccation of silkworm cocoons, such as mass power ratio, thickness of laying and subsection desiccation, we studied the silkworm cocoons during the process of microwave desiccation. The result indicated that mass power ratio has an important influence on drying rate, while the thickness of laying has a little;when the mass power ratio is more than 8 W/g,the pupae in the cocoons burst, which would affect the quality of cocoons desiccation, the subsection desiccation benefits the processing of desiccation, microwave desiccation of cocoons improves the efficiency of desiccation and the neatness degree of silk.
