摘　　要：苜蓿属热敏性物料,热风温度的高低直接影响干燥过程的能耗、干燥质量及效率。为此,以紫花苜蓿为研究对象,在东北农业大学干燥试验室薄层干燥试验台上,进行了热风温度对紫花苜蓿薄层干燥速度影响的试验研究,建立了不同介质温度苜蓿干燥特性曲线及介质温度与降水幅度模型,为牧草干燥机的设计提供可借鉴的参数。Alfalfa is a materiel that is sensitive to temperature. Energy loss, drying quality and drying rate are directly affected by the wind temperature. The effect of temperature on alfalfa drying rate was researched on the test table of forage straw thin - layer drying that was made by northeast agriculture university. The graph of a relation between temperature and alfalfa drying character was found, and the mathematic model between temperature and precipitation extent was made. The research provided a scientific reference for the design of forage straw drying machine.
