摘要
为回顾近年来载能微波在农产品干燥中的研究进展,并解析负压环境对干燥行为的影响,文章以微波干燥的负压水平和干燥模式为主线,阐述高水分农产品物料在低真空度的负压微波脉冲喷动干燥(pulse-spouted microwave vacuum drying,PS-MVD),中真空度的微波真空干燥(microwave vacuum drying,MVD),高真空度的微波真空冷冻干燥(microwave vacuum freeze drying,MVFD)的干燥模式及物料特性,同时对农产品物料“热风-微波真空”组合干燥、“微波真空-真空含浸”加工、“脉冲喷动微波真空冷冻干燥”工艺的创新应用展开讨论。
In order to review the research progress of energy carried microwave in agricultural product drying in recent years,and expound the influences of negative pressure environment on drying quality,this paper expounded the drying mode and material quality of high-moisture agricultural products in low vacuum pulse-spouted microwave vacuum drying(PS-MVD),medium vacuum microwave vacuum drying(MVD)and high vacuum microwave vacuum freeze drying(MVFD)based on negative pressure level.In addition,the innovative application of“hot-air microwave vacuum”combined drying,“microwave vacuum-vacuum impregnation”processing and“pulse-spouted microwave vacuum freeze drying”processes for agricultural products were discussed.
