摘　　要：在对农作物秸秆基本特性分析的基础上,结合不同类型干燥技术的特点与适用性,提出秸秆多级协同干燥工艺方案,并分别对搅拌干燥、脉冲气流干燥、三回程转筒干燥装置和辅助系统进行设计与试验。以玉米秸秆为原料,系统性能测试结果表明：原料入机含水率为29.5%,出机含水率为8.4%,工作环境噪声为75.6 dB,原料处理能力为3.92 t/h,可满足后端生物质成型生产线要求。Based on the analysis of the basic feature of the crop straw, applicability of the different types of drying technology, the multi- stage and combining with the characteristics and coordinated drying process of straw was put forward. Agitation drying, pulse air-streaming drying, three cylinder rotary drying and auxiliary system are designed and tested. The testing results with corn straw showed that the moisture content of raw materials is 29.5%, the water content of the material out the machine is 8.4%, the working environment noise is 75.6 dB, and the raw material processing capacity is 3.92 t/h, which could meet the requirements of biomass compression molding.
