【摘要】 针对小麦热风干燥中存在的问题,运用微波试验装置,通过选择不同的干燥功率、物料铺放厚度及排湿风速,研究了小麦微波干燥特性及其对干后品质和能耗的影响。研究结果表明:小麦微波干燥主要处于恒速阶段,微波干燥对小麦品质有显著的影响,小麦籽粒的发芽率和SDS沉降值对微波处理的反应比较敏感,可以作为小麦热损伤的指标和小麦品质变化的检测指标,小麦微波干燥能耗主要受排湿风速影响。更多还原

【Abstract】 In view of existing problems in the hot air drying of wheat grain,experimental study on characteristics of microwave drying of wheat grain and the influence of microwave drying conditions on the quality of wheat grain and energy consumption were conducted using home-made microwave drying and testing device by choosing diffrent power of microwave,thickness of materials and airflow rate.The results show that the constant drying rate is the main stage of microwave drying of wheat grain,the quality indicators of wheat grain are influenced by microwave drying conditions obviously,and germination rate and SDS sedimentation volume of wheat grain are sensitive to the intensity of microwave drying.So the germination rate and the SDS sedimentation volume may be regarded as main indicators of heat injury and the quality of wheat grain.The drying energy consumption is influenced mainly by the airflow rate of microwave drying.更多还原
