Abstract

Abstract: To better promote the large-scale standardized processing of oolong tea, improve the rocking green quality and machinery efficiency, and extend the application scope of equipment, an amplitude adjustable imitation manual rocking green device and a single input multi output power transmission mechanism were designed. The kinematics analysis model of the amplitude adjustable rocking green mechanism was established, and the spatial motion trajectory of the spherical screen was simulated by MATLAB. On this basis, a rocking green prototype was developed to carry out the multi index orthogonal test of 2 factors and 4 levels of the rocking green. Then, the multi index was transformed into a single index by comprehensive scoring method, and the best process parameters were btained by the orthogonal test analysis. Under the optimal process parameters, the moderate rate of oolong tea rocking green was 84.10%, the water loss rate was 33.63%, and the comprehensive score was 97.75% of the traditional manual rocking green. The experimental results show that the developed amplitude adjustable imitation manual rocking green mechanism is effective. On the basis of matching the relevant process parameters, it can be applied to the large-scale mechanical rocking green of fresh leaves in different tenderness and seasons. Meanwhile, it also provided a new reference method for the research of relevant process parameters in the field of tea processing.

Key words: oolong tea, rocking green, amplitude adjustable, orthogonal test, process parameters
