农产品微波干燥技术与装备的研究进展

摘要

Microwave drying technology was discussed in the pape.Firstly,the research progress and ap-plication of microwave drying technology in the processing of agricultural products were introduced,and the problem of uneven drying,local burns and other defects in microwave drying process were put forward.Then e-laborated the current technology and equipment′s research process in hot-air microwave fluidized drying,vacu-um microwave drying,vacuum freeze microwave drying and other combined microwave drying methods.With the analysis of the advantage and disadvantage of different drying technologies,the technology of microwave combined drying process is the development trend of the microwave drying industry of agricultural products.%以微波干燥技术为研究对象，首先阐述了微波干燥技术在农产品加工中的研究现状，并提出了微波干燥中干燥不均、局部灼伤等技术问题。然后综合介绍了热风微波流态化干燥、真空微波干燥、冷冻微波干燥等组合工艺与装备的研究进展。最后通过分析不同加工工艺的优势和不足，提出了微波组合干燥技术是农产品微波干燥工业的发展趋势。
