猕猴桃太阳能组合干燥装置的设计

为缩短猕猴桃的干燥时间，降低干燥成本，利用中国西北部地区充沛的太阳能资源，设计了以槽式太阳能与常规能源相结合为热源的猕猴桃组合干燥装置．结合猕猴桃的干燥特性，确定了干燥装置的总体结构设计方案，完成了集热、干燥等关键部件设计选型，并对核心部件真空干燥箱进行了改进，使其具有热风真空两种功能．并利用该装置进行了猕猴桃脆片干燥试验．试验结果表明，应用太阳能组合干燥装置满足了设计目标，缩短了干燥时间，大大降低了干燥成本，干燥质量明显提高．

Design of solar combined drying device for Kiwi-slices

In order to reduce drying time and cost in Kiwi-slices drying process, a Kiwi-slices combined-drying devices was designed with the combination of solar and conventional source as heat energy, based on abundant solar energy resources in Northwest China. The overall structure as well as critical components were designed according to characteristic of Kiwi- slices. Experimental results suggested that this achievement met the original objective and requirements for quality improvement and energy saving of Kiwi-slices
