Abstract

Abstract: Research on an implement method to determinate tea moisture content with rapid non-destructive and on-line technology. Comparing to national standard method, it was proved that the effect of those factors including the dynamic and static state of conveyor belt, spread thickness, measuring height, tea grade on the accuracy of tea moisture content accuracy. The results showed that there were significant differences between CK and different spread thickness and grade, no obvious difference in the treatment of dynamic or static state and measure height. The optimal parameters are that tea conveyor belt speed is 0.8 m·s^-1, conveyor belt should be fully covered by tea samples, and should avoid from the external light irradiate tea samples, spread thickness is (20±5) mm, measure height is (250±50) mm. Different grade of tea set at different measuring channels can be more accurate in measured results.

Key words: tea, moisture content, near-infrared, on-line, influence factors
