An orthogonal experiment was conducted to study the main affecting factors in the shape-making process of needle-shaped famous green tea, based on the optimum plan for the combination of machine-processing techniques and the corresponding machines.

6CZZ-600 shaper and its optimized technology for famous needle-type tea;
