摘　　要：为助推乌龙茶的大规模标准化加工,提高摇青机械的摇青质量和效率,增进装备的适用范围,设计了可调幅仿手工摇青机构和单输入多输出的动力传输机构,建立了该可调幅摇青机构的运动学分析模型,利用MATLAB软件仿真得到球形筛的空间运动轨迹。在此基础上,对研制的摇青样机进行了乌龙茶摇青2因素4水平的多指标正交试验。采用综合评分法将多指标转化成单一指标,并通过正交检验分析得到较优工艺参数。在较优工艺参数下的乌龙茶摇青适度率为84.10%,失水率为33.63%,综合评分达到传统手工摇青的97.75%。试验结果表明,设计的可调幅仿手工摇青机作业有效,在相关工艺参数得到匹配的基础上,可适用于不同季节、不同嫩度鲜叶的规模化和标准化机械摇青;同时也为茶叶加工领域的相关工艺参数研究提供了一种新的解决思路。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 obtained 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.
