Aiming at herbage seed drying equipment problems of power consumption, air discharge and solar energy application, a drying mode was proposed. Basis heating was supplied by thermalstored solar energy, and air charge was dehumidified and reused by heat pump. Main working parts, such as thermal collector, thermal storage and heat pump, and whole drying machine were designed. Using movable design idea, thermal collector was controllable and whole machine was placed safely. Performance test results showed that handling capacity reached to 161kg/h, power handling capacity achieved to 8.4kg/(kW?h), the drying capacity reached to 3.367kg?%/h, and dry strength achieved to 6.7kg/(m3?h). The power consumption ration of solar PCM heat-storage drying, solar energy and heat pump teamwork drying, heat-pump drying and electricity power drying was 0.9∶1.0∶1.2∶1.5. 
