Development of Tea Carding Machine for Chinese Green Tea

摘要

The tea carding machine was designed, developed and its performance was evaluated. The major parts of the tea carding machine were main frame, electromotor, transmission framework, electric heater. The transmission was crank slider mechanism. The orthogonal experiment of 7 factors 3 levels was adapted to optimum structural Parameters. The result showed: crank length was 59 mm, crank speed was 130 m, connecting rod length was 442 mm , eccentricity was 57 mm, the height and depth of the U-shaped unit was 110 mm and 80 mm respectively, the total power of far infrared metal heating tubes was 11 kW, the stripping tea rate was 89.5 %.
