Abstract:20℃(3.5 h)→25℃(3.5 h)→30℃(3.5 h)→35℃(3.5 h)。Horse mackerels were dried in a heat pump dehumidifier (HPD) which is capable of producing stepwise control of drying air temperature. Two stepwise air temperature profiles were tested. The drying characteristics and total color difference (ΔE) of the products dried under these stepwise variation of temperature were measured and compared with constant air temperature drying. It was observed that by employing stepwise change in drying air temperature with the appropriate starting temperature and cycle time, it was possible to reduce drying time to reach the desired moisture content with significantly improved product color. The optimum condition for time-varying temperature drying of horse mackerel was step-up profile with initial temperature of 20℃ and cycle time of 3.5 h. 

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.
