摘要
为了缩短枸杞干燥时间、降低干燥成本并提高产品质量,结合热泵、高效集热器、换热器和蓄热等节能产品与技术,研究设计了枸杞太阳能组合干燥装置(集主动式和被动式相结合的太阳能储存与利用设备),并对该干燥装置进行了应用试验。结果表明:新型集热器日平均瞬时集热效率为65.6%,较传统集热器集热效率约高17%。枸杞干燥试验,枸杞太阳能组合干燥装置平均干燥周期约33h,比自然晾晒干燥周期缩短约2/3,大量节省常规能源,且产品质量高,节能减排效果明显。
The solar combination drying equipment（the solar energy storage and utilization equipment with the combination of active and passive pattern was designed based on the energy-saving products and technology of heat pump,efficient heat collector,heat exchanger and thermal storage to shorten drying time of Chinese wolfberry and reduce drying cost and improve wolfberry quality.The results showed that the daily average momentary heat collecting efficiency of the new heat collector reaches 65.6%,17%higher than the traditional heat collector.The average drying period of the solar combination drying equipment to dry Chinese wolfberry is about 33 h,about 55 hless than the natural air drying pattern.The solar combination drying equipment with high energy conservation and emission reduction efficiency and high Chinese wolfberry quality can be used in drying of Chinese wolfberry.
