中文摘要:为提高茶鲜叶分级效果,设计了一种参数可调的等直径滚筒式分级机。在计算确定滚筒主要结构参数的基础上,通过正交试验优化了滚筒倾角、进料率和滚筒转速等工作参数。用正交表L 25 (5 6 )安排试验,分析了茶鲜叶分级过程中的滚筒倾角、进料率、滚筒转速对茶鲜叶总体分级率的影响。结果表明,各因素对总体分级率影响的主次顺序为:滚筒倾角、进料率和滚筒转速。本试验条件下,综合考虑分级率和生产率,工作参数的最优组合为:滚筒倾角6°、进料率3.0 kg/min和滚筒转速16 r/min。

Abstract:In order to improve the screening effect of fresh tea leaves, an equant-diameter roller screening machine was developed with adjustable structural and technical parameters. The main parameters of roller rotating speed, roller diameter and roller length were calculated, and the model selection of driving motor was done. The optimal parameters combination of roller inclination, rotating speed and feeding rate was made based on the orthogonal test. The treatments were arranged according to orthogonal table L 25 (5 6 ), and the influence of each parameter on screening rate was analyzed. The results showed that the sequence of each parameter’s influence on total screening rate was roller inclination, 〖JP3〗feeding rate and rotating speed, and screening rate reached the maximum when roller inclination was 6°, feeding rate was 1.5 kg/min and rotation rate was 16 r/min. To double the screening productivity, feeding rate should be selected as 3.0 kg/min, while correspondingly total screening rate was dropped by only 3.3% averagely.

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.
