Abstract

The invention discloses a new ancient-method preparation process of jujube-bud black tea. The process comprises the following steps: sorting and tedding, sunning, withering, rocking, automatic weighing, rolling, fermenting, composite primary drying, forming and deblocking, secondary drying, primary preparation and aroma enhancing, static aged storage, and alcoholization refining aroma enhancing. According to the new ancient-method preparation process of the jujube-bud black tea, quick-heating withering process equipment is specially designed according to different water contents of coarse and old leaves and different properties of green leaves, so that the requirements of quality control and large-scale production can be met; the water content of the tea leaves is more uniform by utilizing atomized water adding, and polyphenol substances in the tea leaves generate oxidative polymerization under the enzymatic action through aerobic fermentation; the microwave frequency is high, the temperature of a material is rapidly increased by heat so as to achieve the effect of rapidly heating to remove green and astringent taste, the jujube-bud black tea is newly prepared by using an ancient method, the unique taste and the quality of jujube leaf tea are improved; and furthermore, alcoholization aroma enhancing has a sterilization function and has the significant effect of removing the bitter and astringent taste of the tea. A powerful process technology guarantee is provided for high-end tea enterprises.

Description

technical field [0001] The invention belongs to the technical field of jujube bud black tea processing, and in particular relates to an ancient and new preparation process of jujube bud black tea. Background technique [0002] As we all know, Linxian County is the "hometown of red dates in China", located at the magical 37° north latitude. Jujube trees are drought-resistant and have strong vitality, known as "hardcore crops". Linxian red dates are bred in the wild and pollution-free Huangshi hilly and ditch areas, which are sweet and sour, and rich in nutrition. It is known as "three dates a day, and you will live forever". The planting area of ​​jujube in Linxian County is 820,000 mu. According to the statistics of picking jujube buds and leaves in the past three years, the yield per mu is about 1,000kg. Due to the tall crown of jujube trees and the vertical and horizontal ditches in the growth area, the effective picking rate of one quarter is calculated. An average of 25...
