摘　　要：建设太阳能－热泵联合干燥示范平台，以期更好推广其在干燥行业的应用。使用自动控制系统，实现对干燥过程中恒温操作，并采用智能启停的热回收器回收排放的废热。基于干燥系统平台对新鲜蔬菜进行干燥实验，测试结果表明：新开发的联合干燥系统的能耗比传统干燥方式降低3～4倍，干燥后的菜干品相上乘。实验证明，本次开发的智能控制干燥系统节能减排效果显著，适合在干燥行业推广应用。An exemplary platform of solar-heat pump drying system was established so as to promote its application in drying industry. Constant temperature operation in drying process is achieved by the au- tomatic control system, and waste heat is reclaimed by heat recoverer with intelligent start/stop device. Based on this drying system platform a drying experiment of fresh vegetables was conducted. The results show that energy consumption of the new drying system reduced to one third or one fourth in compari- son with the traditional drying method. The dried vegetables by the new drying system have good ap- pearance and high quality. The experiments confirmed that the new intelligent drying system have effec- tive performance of energy saving and emission reduction. It is suitable for extensive application in dr- ying industry.
