摘要
在对水稻间歇式顺流干燥工艺的试验研究中，借助于自行研制的顺流干燥试验台，采用二次旋转正交组合试验设计方案，研究了热风温度、表现风速、干燥时间、谷层厚度四因素对单位热耗、最终水分、爆腰率增值、小时去水量、小时降水率、干燥强度等性能指标的影响，建立了描述稻谷间歇式顺流干燥工艺的数学模型；用图形法分析干燥工艺参数对主要性能指标的影响。试验表明，间歇式顺流干燥工艺具有干燥均匀、能耗低、烘后粮食品质好等优点。
In order to study the intermittent concurrent flow drying, a drying test apparauts is built By using the secondary orthogonal roating combine torial design, the effect of drying technology parameters on the property indicators is studied,the corresponding mathematics model is set upThrough regression analysis, and the optimum parameters combination of the drying technologies is obtained and verified These parameters and models could be used to devise an intermittent drying process schedule
