名优绿茶清洁化做形技术研究

Study on Cleansing Shaping Technology of Brand-name and Quality Green Tea

[目的]研究名优绿茶相配套的清洁化做形技术,为促进清洁化连续加工设备的推广与应用提供参考。[方法]以名优绿茶筑阳翠峰茶为对象,研究清洁化连续加工中理条设备6CLZ-60型多用理条机清洁化做形技术,利用单因素试验和正交试验研究了含水量、做形温度、投叶量、理条机转速、做形时间对茶叶品质的影响。[结果]感官审评和主要品质成分的检测分析表明,在含水量控制在40%左右,做形温度在130℃左右,转速为600 r/m in左右,投叶量为70 g/槽左右,做形时间为10 m in左右时的组合有利于筑阳翠峰茶品质的形成。[结论]该研究为名优绿茶清洁化做形技术提供了理论依据。

[Objective]The aim was to study on the cleansing shaping technology matched with the brand-name and quality green tea so as to provide the reference for promoting the popularization and application of tea cleansing and continuous processing facilities.[Method]With the brand-name and quality green tea Zhuyang Cuifeng Tea as the material,the cleansing shaping technology with the clay-strip equipment 6CLZ-60 type multi-purpose clay-strip machine in the continuous cleansing processing was researched and the effects of water content,shaping temperature,adding leaf quantity,clay-strip machine speed and shaping time on the tea quality were also studied through the single factor experiment and orthogonal test.[Result]The results from the sensory evaluation and the testing analysis on the main quality components of the tea samples suggested that the combination as the moisture content of 40%,the shaping temperature of 130 ℃,the rotor speed of about 600 r/min and the adding leaf amount of 70 g per slot were highly favorable for the quality formation of Zhuyang Cuifeng Tea.[Conclusion]The study provided the theoretical basis for the cleansing shaping technology matched with brand-name and quality green tea.
