Abstract:Research on vacuum infrared radiation drying of Rehmanniae was carried out u sing an improved vacuum infrared radiation dryer. By means of logarithm of experimen tal data and linear regression, the pattern of thin layer vacuum infrared dryin g model of Rehmanniae, which was related to the temperature of radiation boa rd a nd pressure in the chamber, was set as Modified Page equation, and the expressio n and values of model parameters were also obtained subsequently. The model coul d describe and predict change regulation of moisture ratio very well according t o the comparison of experimental values and calculated values.

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.
