The scheme discloses the technical field of tea processing. The withering process of white tea is firstly carried out by natural withering, then by alternating hot wind withering and cold wind withering, the first hot wind withering is carried out: the tea leaves are withered in the withering trough, the spreading thickness of the tea leaves is 20-30 cm, the temperature of the hot wind is 50-55 C, and the withering time is 15-20 min. The first cold wind withered: the temperature of cold wind was 5-10 C, withering time was 40-50 min; the second hot wind withered: the temperature of hot wind was 30-40 C, withering time was 50-60 min; the second cold wind withered: the temperature of cold wind was 10-15 C, withering time was 30-40 min. The scheme of the invention firstly wilting the tea leaves naturally, and then wilting the tea leaves naturally by laying the tea leaves at a thickness of 1.5-3 cm. Under such a thickness condition, the tea leaves can gradually lose water in the natural state. After 1-1.5 hours, the tea leaves can basically disperse the free water, and at the same time become soft, without appearing. Soft and thin.

白茶的萎凋工艺
本专利技术涉及茶叶加工
,具体涉及白茶的萎凋工艺
技术介绍
白茶属于微发酵茶,是中国茶农创制的传统名茶,也是中国六大茶类之一。白茶的加工工艺,是将采摘下来得鲜茶叶,不经过发酵,只经过萎凋和文火干燥既得。目前,白茶的萎凋方式主要包括以下三种:室内自然萎凋、加温萎凋以及复式萎凋。室内自然萎凋历时较长,生产速率慢,遇到阴雨天气,气温低且空气湿度大,易造成叶片发黑甚至霉变;加温萎凋对于环境控制技术要求较高,若调控不当,容易造成白茶萎凋程度不均匀,使白茶有异味,影响茶叶品质,且单纯依靠热风萎凋加工能耗较高;复式萎凋虽然结合了自然萎凋与加温萎凋的工艺,克服了自然萎凋和加温萎凋的缺点,但受到白茶实际生产过程中诸多方面的限制,上述白茶的萎凋方式中均存在茶叶萎凋不均匀的情况,导致白茶最终生产的成品易存在红张、暗张、蜡叶等问题。
技术实现思路
本专利技术意在提供一种白茶的萎凋工艺,以解决现有白茶工艺中茶叶萎凋不均匀的技术问题。为了解决上述技术问题,本专利技术提供如下技术方案:白茶的萎凋工艺,包括以下步骤:步骤一、自然萎凋:采摘的茶树鲜叶放置在萎凋架上,铺放厚度为1.5~3cm,萎凋时间为1~1.5h,中途翻动2~3次;步骤二、第一次热风萎凋:将茶叶置于萎凋槽中萎凋,茶叶摊放厚度为20~30cm,热风温度为50~55℃,萎凋时间为15~20min;步骤三、第一次冷风萎凋:冷风温度为5~10℃,萎凋时间为40~50min;步骤四、第二次热风萎凋:热风温度为30~40℃,萎凋时间为50~60min;步骤五、第二次冷风萎凋:冷风温度为10~15℃,萎凋时间为30~4 ...
