Embodiment 1

[0016] (1) Raw material collection of purple buds and leaves: The unique geographical environment and strong light influence in Southwest Guangxi produce periodic purple buds and leaves. The raw materials are purple buds and leaves with one bud and one leaf. They are packed in breathable bamboo baskets and transported without machinery damage;

[0017] (2) Cooling: put the purple buds and leaves on the dustpan and place them on the withering rack, let the purple buds and leaves raw materials lose part of the water, and the water loss rate is 3-5%;

[0018] (3) Hot air finishing: put the cool raw materials in step (2) into the drum for high temperature hot air finishing, the finishing temperature is 180-200°C, it is advisable to kill cooked and thoroughly;

[0019] (4) regain moisture: the raw material after step (3) is cooled and regain moisture, its effect is to reduce leaf temperature and make moisture redistribute, be beneficial to next step and knead;

[0020] (5) light k...

Embodiment 2

[0025] (1) Raw material harvesting of purple buds and leaves: the unique geographical environment in Southwest Guangxi and the influence of strong light produce staged purple buds and leaves, and the raw material is purple buds and leaves with one bud and three leaves;

[0026] (2) Cooling: put the purple buds and leaves on the dustpan and place them on the withering frame, let the purple buds and leaves raw materials lose part of the water, and the water loss rate is 3-5%;

[0027] (3) Hot air finishing: put the cool raw materials in step (2) into the drum for high temperature hot air finishing, the finishing temperature is 180-200°C, it is advisable to kill cooked and thoroughly;

[0028] (4) regain moisture: the raw material after step (3) is cooled and regain moisture, its effect is to reduce leaf temperature and make moisture redistribute, be beneficial to next step and knead;

[0029] (5) light kneading: put the raw material after step (4) moisture regain into kneading m...

Embodiment 3

[0034] (1) Raw material harvesting of purple buds and leaves: the unique geographical environment in Southwest Guangxi and the influence of strong light produce staged purple buds and leaves, and the raw materials are purple buds and leaves with one bud and two leaves;

[0035] (2) Cooling: put the purple buds and leaves on the dustpan and place them on the withering frame, let the purple buds and leaves raw materials lose part of the water, and the water loss rate is 3-5%;

[0036] (3) Hot air finishing: put the cool raw materials in step (2) into the drum for high-temperature hot air finishing, the finishing temperature is 190°C, and it is advisable to kill cooked and thoroughly;

[0037] (4) regain moisture: the raw material after step (3) is cooled and regain moisture, its effect is to reduce leaf temperature and make moisture redistribute, be beneficial to next step and knead;

[0038] (5) light kneading: put the raw material after step (4) moisture regain into kneading m...

Abstract

The invention discloses a special green tea processing method, which comprises the following steps: spreading and cooling tea tree purple buds and leaves, carrying out hot air water removing, regaining moisture, slightly rolling, curling and shaping, and drying to obtain the green tea, wherein after spreading for cooling, hot air water removing is performed in time, tea polyphenol oxidation can beprevented, part of moisture and grass smell can be emitted, and tea fragrance development is facilitated; purple bud leaves are large summer tea raw material leaves, hot air water removing is conducted in time to soften the leaves, rolling and curly shaping are facilitated, a shaping machine is used for curly shaping on the basis of traditional green tea processing, the appearance is attractive,and packaging and transportation are facilitated. According to the invention, a purple bud leaf product, namely the special green tea, is developed, the purple bud leaf raw material is fully utilized,the waste of the raw material in summer is avoided, the method has important significance for increasing the income of tea growers and adjusting the tea industry structure, and the innovation of thetea industry and health-care industry fusion mode is promoted.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a characteristic green tea processing method. Background technique [0002] The formation and accumulation of purple buds and leaves of tea trees are closely related to the growth environment of tea trees. The green tea production in southwestern Guangxi from May to August can reach more than 40% of the annual output. Staged purple buds and leaves, some tea trees sprout and grow faster and are easy to form purple buds and leaves, and their anthocyanin content is higher. [0003] In the past, the tea made from it tasted bitter and of poor quality in summer, so it was not picked in the way of growing awnings. In recent years, with the deepening of scientific research, the medical and health functions of anthocyanins, the main component of the purple buds and leaves of tea trees, have been discovered. was gradually proven. Anthocyanins are a kind of water-solubl...
