Abstract: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. 

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
