The invention discloses the yellow-mugging process of yellow tea, which includes the following procedures: placing the green tea in a sealed placement bucket, a cavity is arranged at the center of the placement bucket, and an absorption component for absorbing the moisture generated by the green tea in the process of the yellow-mugging is installed in the cavity; then placing the placement bucket containing the green tea in the water bath heating container, and ensuring the water temperature dimension of the water bath heating container. Hold at 35 40 C; Open the intake and exhaust pipes and enter oxygen to speed up the oxidation and hydrolysis process of the substances in tea until the green tea presents uniform orange or golden color and stops frowning. The invention adopts the water bath heating method to muggy the green tea, shortens the muggy time, improves the muggy efficiency, and uses the adsorption parts to quickly absorb the water vapor generated during the muggy tea process; on the other hand, it effectively improves the problem of uneven and incomplete yellowing caused by the high moisture content of the traditional green tea, and is effective through the adsorption function, oxygen supply, temperature and humidity. Control to improve the quality of yellow tea.

黄茶的闷黄工艺
本专利技术属于茶叶加工
,尤其是涉及一种黄茶的闷黄工艺。
技术介绍
黄茶是我国六大茶类之一,属于轻发酵茶,主要的品质特点是黄叶黄汤。黄茶成茶外形条索紧结肥厚,色泽金黄油润,白毫显盛,香气清雅。冲泡之后,汤色橙黄明亮,滋味醇和鲜爽、回甘。黄茶的基本工艺是:杀青、揉捻、闷黄、干燥。其中,“闷黄”是形成黄茶品质的关键,也是黄茶加工的典型工艺,是形成黄汤黄叶的重要工序。黄茶以原料采摘的标准不同分为黄大茶、黄小茶、和黄芽茶,按闷黄方法可分为干坯闷黄和湿坯闷黄。湿坯闷黄的茶坯含水率较高,黄变较快,闷黄时间较短,一般为6-8小时,干坯闷黄的茶坯含水率较低,黄变较缓慢,闷黄时间较长,一般为5-7天。通常来说,闷黄时间过短会导致黄变不足,滋味浓涩,汤色叶底偏青,随着闷黄时间的延长,多酚类含量下降,氨基酸含量上升,酯型儿茶素含量减少,水浸出物含量稍有提升,而闷黄时间过长,会导致反应过度,酚氨比上升,可溶性糖含量因消耗过度下降,黄茶滋味物质减少,汤色叶底黄暗。近年来,黄茶因其香气清悦、味厚爽口的特点越来越受到广大消费者的欢迎,而传统黄茶闷黄时间较长,生产效率低,品 ...
【技术保护点】
1.黄茶的闷黄工艺,其特征在于,采用水浴加热容器对茶湿坯进行闷黄,包括如下步骤:S1、首先将揉捻后的茶湿坯置于安置桶中并密封;所述安置桶的中心处设置有若干个空腔,空腔内安装有用于吸收闷黄过程中茶湿坯产生的水闷气的吸附部件;在安置桶上还设置有进气管和排气管,初始时进气管和排气管均处于封闭状态;S2、接着将安置桶安放在水浴加热容器中,并确保水浴加热容器中的温度保持在35‑40℃;S3、然后同时打开进气管和排气管,并通入氧气以加速茶湿坯中水闷气的排出,待1‑2分钟后,关闭排气管,继续通入氧气1‑2分钟;S4、重复执行上述步骤S3两到三次,直至茶湿坯呈现出均匀的橙黄色或金黄色,停止闷黄。
