Description

Black tea fermenting and yellow tea stuffing yellow all-in-one machine

technical field

The utility model belongs to the technical field of tea processing, in particular to a dual-purpose machine for fermenting black tea and stuffing yellow tea.

Background technique

Yellow tea is a kind of lightly fermented tea, and its processing technology is similar to that of green tea, except that before or after the drying process, a "suffocating yellow" process is added to promote the partial oxidation of its polyphenols, chlorophyll and other substances. Its processing method is similar to that of green tea, and its production process is as follows: fresh leaves are greened, twisted, yellowed, and dried. Yellow tea’s greening, rolling, and drying processes are similar to those of green tea. The most important process is yellowing, which is the key to the characteristics of yellow tea. The stuffy yellowing process needs to be carried out in an environment with relatively low oxygen content or anaerobic environment. At present, the main method is to wrap the green and rolled tea leaves with paper, or cover them with a damp cloth after stacking. The time can be tens of minutes or several hours. The tea dregs are promoted to undergo non-enzymatic auto-oxidation under the action of hydrothermal heat to form a yellow color.

The steps of this yellowing process are cumbersome, and it is difficult to provide a relatively good low-oxygen or anaerobic environment for paper packaging or wet cloth coverage. Moreover, the yellowing of the tea dregs during the accumulation process also has uneven yellowing, resulting in a decline in the quality of yellow tea. .

Also not being specially used in making yellow tea in the market, or being used for carrying out the equipment of stuffy yellow process of yellow tea. However, there are many equipments for black tea fermentation, and the production process of black tea usually includes processes such as fresh leaves withering, rolling, fermentation and drying. During the processing of black tea, a chemical reaction centered on the enzymatic oxidation of tea polyphenols occurred, the chemical components in fresh leaves changed greatly, tea polyphenols were reduced by more than 90%, and new components such as theaflavins and thearubigins were produced . The aroma substances are significantly increased compared with fresh leaves, so black tea has the characteristics of black tea, red soup, red leaves, sweet and mellow.

The production of black tea usually includes the processes of withering of fresh leaves, rolling, fermentation, and drying to enhance the aroma. The fermentation, drying, and aroma enhancement processes are the key steps. For high-quality black tea, the fermentation, drying, and aroma enhancement processes must be completed in one go to ensure rapid passivation after fermentation. The active enzymes in the tea prevent further fermentation and affect the quality. The Chinese utility model patent application with the publication number CN 103431092A discloses a black tea fermenting, drying and aroma enhancing integrated machine. The device includes a box body with a cavity inside. A bracket for placing tea leaves and a fan facing the air inlet are provided in the cavity, and a humid and hot gas flow path driven by the fan and passing through the bracket is formed between the air inlet and the air outlet. Although the above-mentioned equipment feeds hot and humid gas into the tea leaves through the hot and humid gas flow path to provide fermentation conditions for black tea fermentation, it does not solve the technical problem of uniform contact between the hot and humid gas and the tea leaves, so the quality of the prepared tea leaves is not high.
