Abstract

Abstract: To solve the problems caused by unstable quality in the process of tea twisting, the 6CR-40 tea twisting machine was taken as the research object in this study. The three-dimensional modeling of tea twisting machine was established based on Solidworks. The numerical simulation of the twisting process of tea twisting machine was carried out by the discrete element simulation software EDEM. The influences of various experimental factors on the performance indexes of tea twisting machine were obtained. The quadratic orthogonal rotation test was carried out and the Design-Expert was used to optimize the solution and obtain the best combination of structural parameters of twisting quality. The results showed that: when the twisting barrel rotational speed, the prismatic height, twisting plate inclination angles, forming rate of tea and breaking rate of tea were 42 r·min^-1, 10 mm, 3.8°, 88.55% and 1.83% respectively, the tea twisting machine had a good quality of twisting. The results of verification test and simulation optimization were basically consistent.

Key words: tea twisting machine, EDEM, simulation analysis, quadratic orthogonal rotation test, response surface method
