Description

A tea withering fermentation room

technical field

The utility model relates to a tea withering fermentation room, which belongs to the field of tea preparation.

Background technique

Fermented tea is a kind of tea making process. It refers to the tea made from tea tree buds and leaves after withering, kneading, cutting, fermenting, drying and other primary processes to make raw tea, and then refined.

Withering is to spread the picked fresh leaves according to a certain thickness, and to make the fresh leaves appear wilted by drying. During the withering process, a series of changes occur in fresh leaves: the water decreases, the leaves become soft from brittle and hard, and are easy to knead into strips; the activity of enzymes contained in the leaves is enhanced, which promotes the growth of fresh leaves such as starch, protein, and insoluble protopectin. The ingredients are decomposed and transformed to produce effective substances such as glucose, amino acids, and soluble pectin that are beneficial to the quality of tea, and polyphenols are also oxidized to varying degrees. Normal and effective withering will make the green leaves of fresh leaves fade away and produce a delicate fragrance, with fruity or floral fragrance, and the finished tea tastes mellow but not bitter. Withering requires conditions such as suitable temperature, humidity and air circulation. Traditional withering methods include sunlight withering (sun drying), indoor natural withering (spreading), and compound withering using the above two methods. Different teas have different requirements for the degree of withering. White tea has the most serious withering degree. The water content is required to be reduced to less than 40%. The degree of withering of black tea is the second highest, and the water content is reduced to about 60%. The degree of withering of green tea is the lightest, and the water content is required to be between 68-70%. During the withering process, the water loss rate is too fast, the withering time is too short, and the chemical components contained in it cannot change normally, which affects the quality of withering.

Fermentation is based on normal withering and rolling to further enhance the activation of enzymes, promote the oxidation and condensation of polyphenolic compounds, and form the unique color and taste of tea. Under suitable environmental conditions, the leaves can be fully fermented and green Astringent smell, and produce a strong aroma. The fermentation process must have suitable environmental conditions in order to obtain good results. Ventilation and humidity control are the key; the chemical effects produced by the withering and fermentation process involve a wide range, and are closely related to the aroma, taste and soup color of tea; and are affected by the local temperature. It is related to humidity. Poor temperature and humidity control can easily affect the quality and taste of tea. Therefore, how to balance the relationship between temperature, humidity, air circulation and other factors is the key to obtaining high-quality tea.
