为改变传统黑毛茶松柴明火干燥影响茶叶品质安全的问题,试验以云台山大叶种黑毛茶精加工的天尖进行不同干燥方法研究,比较了七星灶、炭烘、电烘三种不同干燥方法,对茶叶品质进行了理化分析、感官审评和能源消耗分析。结果表明,七星灶干燥产品在品质分析和能源消耗上有一定优势,但具有烟熏味;炭烘产品无烟味,但香气比较低且带有发酵味,相关成分含量也较低;电烘干燥过程易于控制,产品理化和感官审评品质较好。

In orde to solve the quality safety problem brought by the traditional pine-smoking drying of Tian-jian Dark Tea, three ways of drying, seven-star stove, charcoal and electricity was tested using Yuntaishan Big Leaf Dark Tea Maocha.
