目前我国扁形茶加工标准化水平不高，为解决中高档扁形茶存在的茶条较松、不够紧直、质量不稳定等品质问题，按照扁形绿茶加工工艺流程和品质形成原理，配备扁形茶的关键加工设备，并设计一条标准化生产线。针对特定嫩度等级鲜叶对各个模块的工艺参数进行优化，并进行生产线测试实验。结果表明：该条生产线设备连接紧凑，布局科学，操作简便，运行平稳。生产出的产品外形扁平挺直、较光滑、匀整，色泽绿翠；汤色绿、明亮；香高；滋味鲜醇；叶底芽叶成朵、匀齐，绿亮，品质符合扁形绿茶产品要求。随着生产效率的提高，产量也大幅提升，经测试干茶日产能达307.20 kg。该条生产线在提高中高档扁形绿茶工效的基础上，还能保障其品质的稳定性，对扁形茶生产企业具有良好的示范效应。

At present, the standardization level of flat tea processing in China is not high. To solve the problems of middle and high-grade flat tea, such as bar loose and not tight straight enough, as well unstable quality, and so on, according to the processing process and quality forming principle of flat green tea, the key processing equipment of flat green tea was equipped, and a standardized production line was designed. The process parameters of each processing module were optimized according to the specific grade of fresh leaves, and the production line test was carried out. The results showed that, this production line has compact equipment connection, scientific layout, simple operation and stable operation. What’s more, the product had a flat, straight and smooth shape, green and uniform color, green and bright liquor color, high aroma and mellow taste. The leaf bottom bud leaf stretched like flower, with a uniform, green and brightcolor. The quality conformed to the request of flat green tea product. With the increase of production efficiency, the daily production capacity of dry tea could reach 307.20 kg. On the basis of improving the efficiency of medium and high-grade flat green tea, this production line could also guarantee the stability of its quality, which has a good demonstration effect for flat tea production enterprises.
