How to process 25kg striped black tea from 100kg fresh tea leaf ? striped black tea need tea withering process, rolling process, tea fermentation and drying, here are machines for your reference and checking.
Machines for making green tea, need four steps, tea withering, tea fixation, tea rolling, and tea drying. Mastering the correct processing method will help you make high-end quality tea.
The process of making unique yellow tea is mostly the same as that of green tea. But a critical process has been added. Makes a huge change in the quality and taste of tea.
Mastering the main influencing factors of drying can make black tea drying fully and give play to the unique qualities of black tea. Using the DELI tea drying machine could help you make the good black tea.
The essence of black tea fermentation is that the fresh leaf cell tissue is damaged. To be precise, the semipermeable vacuole membrane is damaged. Polyphenols can come into contact with endogenous oxidases, causing the enzymatic oxidative polymerization of polyphenols. The role of theaflavin, thearubin and other colored substances. At the same time, the coupling produces a series of chemical reactions of the contained substances, thereby forming the unique aroma substances of black tea. Black tea fermentation is neither microbial fermentation nor simple chemical oxidation, but relies on the enzymatic oxidation of endogenous enzymes in fresh leaves.
Fermentation is the key process of making black tea. Without tea fermentation, the quality characteristics of black tea cannot be formed. If fermentation is abnormal, the quality of black tea will decrease.
During the fermentation process, various internal components have undergone profound changes, such as the oxidation of polyphenols, the destruction of chlorophyll, the hydrolysis of proteins and carbohydrates, and the changes in aromatic substances, among which the most important influence on the quality of black tea Is the oxidation of polyphenols.
The substances contained in tea are gradually transformed during the fermentation process, making the unique aroma of black tea gradually appear in the production.
