Abstract:1.19%。The influence of drying temperature and pressure in the chamber on the drying characteristics of vacuum drying on Cornus officinalis was studied. The regression mathematical models of drying time and content of loganin versus drying temperature and pressure were established. The optimal combination of the parameters for vacuum drying of Cornus officinalis was obtained through nonlinear optimization method with multiple targets. The results showed that the regression mathematical models agreed well with the experimental data, and under the conditions of drying temperature 68.1℃ and pressure 1kPa, the optimal integrative values were obtained as drying time 248min and content of loganin 1.19%, respectively.

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.
