The invention belongs to the technical field of tea processing, and specifically relates to a processing method of orchid fragrant black tea, which includes sunlight opening, indoor spreading, low-temperature quick-freezing, vibration awakening tea, variable temperature fermentation, high-temperature green-killing and solid-phase shaping; the invention adds sunlight opening and indoor spreading processes to make up for the shortcomings of low-temperature quick-freezing and aroma shortcomings caused by too fast fermentation. The cell membrane is destroyed by freezing at low temperature, and then the cell membrane is further destroyed under the vibration of the straightener, so that the blue fragrant black tea can be fully fermented without destroying its shape; the flat shape of the blue fragrant black tea is fixed by the processing method of the blue fragrant black tea provided by the invention; the fragrance, taste and the color of the soup are improved, especially the black tea color performs better; The fermentation time is obviously shorter than the traditional black tea fermentation time, and the processing efficiency is high. The processing method does not need to add new equipment, the process is simple, and has a good application prospect.

一种兰香红茶的加工方法
本专利技术属于茶叶加工
,具体涉及一种兰香红茶的加工方法。
技术介绍
泾县兰香绿茶采摘鲜叶的标准为一芽二叶,干茶外形平直舒展,呈绣剪形。兰香绿茶的加工方法包括杀青、理直、烘干等工序,加工得到的产品色、香、味、形并重,外形比浙江龙井工艺松,比黄山毛峰扁,介于浙江龙井和黄山毛峰之间;泾县兰香绿茶以其独特的色、香、味、形被广大消费者所喜爱,产品已畅销全国各地,销售量已占据长江以南茶叶市场的半壁江山。近几年来,随着红茶在各地的兴起,客户也普遍要求把泾县兰香茶做成红茶。要知道,传统红茶都有揉捻工序,通过揉捻破坏茶叶细胞,达到充分发酵的目的,但兰香茶的外形不能揉捻,否则破坏了外形结构。现有技术中有报道称龙井红茶为了破坏鲜叶红细胞而应用了压榨工艺,但是,压榨虽然能够破坏茶叶的细胞结构,发酵工艺也能完成,但是这一工艺方法容易压碎茶叶,尤其是茶芽和叶边,起不到芽叶完整的作用;同时经过压榨使得龙井的外形过于宽扁,不适合兰香茶的外形。
技术实现思路
针对现有技术中的不足,本专利技术的目的在于提供一种兰香红茶的加工方法,避免破坏兰香红茶的外形,确保充分发酵。为了 ...
