Problems solved by technology

When the existing Usnea tea is greening treatment, the picked fresh leaves are basically spread on a clean bamboo mat or a bamboo plaque, and the greening is naturally greened for 4 to 6 hours. The tea leaves obtained by this greening treatment method appear red. The phenomenon of stalks and red leaves is still very common. The removal of green grass gas from the tea is not ideal, and the aroma of the tea is not well stimulated.

Abstract

The present invention relates to the field of green tea manufacturing, and particularly relates to an usnea diffracta green tea manufacturing method which comprises the following steps: picking fresh leaves, storing green leaves, deactivating enzymes, regaining moisture, rolling, baking, shaping, fixing, improving flavor and packaging. An automatic temperature-controlling cold-air green leaf storage machine is used for the green leaf storing process for a first time. The device can realize the control of the cold air temperature and the blowing of the cold air, better enable the green grass fragrance of the sprouts and leaves to be dispersed and transformed into linalool, geraniol and other substances to produce the flower and fruit fragrance, enable the fresh leaf surface to present a dark green color and a soft hand feeling, and effectively prevent enzymatic oxidation which produces red change phenomenon. The obtained usnea diffracta tea leaves are spiral in shapes and have "flower and fruit fragrance" which is a complex fragrance of castanea mollissima and orchid fragrance.

Description

technical field [0001] The invention relates to the field of green tea production, in particular to a production method of Usnea green tea. Background technique [0002] Songluo tea is a famous historical tea in my country. It is produced in Songluo Mountain, Xiuning County, southern Anhui Province, and was created by monk Dafang during the Hongzhi period of Ming Dynasty. Usnea tea was once an important green tea exported from my country, and it was mainly sold to European countries, and was well received. In January 2012, the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China identified Songluo tea as a product protected by geographical indications. Usnea tea is one of the earliest historical famous teas in my country. The existing Usnea tea is basically plucked, spread green, twisted, baked, shaped, removed, and fragrant to finally obtain granular tea leaves. When the existing Usnea tea is greening treatment, the pi...
