Abstract

The invention discloses a method for processing black tea. The method comprises the steps of picking, spreading for cooling, withering, rolling, fermenting, drying and packaging. Picked fresh tea leaves wither for 3-5 hours at 20-23 DEG C after being spread for cooling, the withered tea leaves are placed into a twisting machine to be twisted for 60-80 minutes and are fermented for 3-5 hours, the fermented tea leaves are dried for 20-30 minutes at 60-80 DEG C, and the tea leaves are dried for 10-20 minutes at 110-120 DEG C to enable the water content to reach 7% or below as to obtain finished raw tea. Shapeless tea leaves and impurities of the finished raw tea are removed, and the finished raw tea is packaged by bark paper or cotton cloth to be placed in a packing case or a packing box and stored at a cool and dry place. The black tea processing technology is simple and practical and large scale production can be achieved.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a processing method of black tea. Background technique [0002] Black tea is the tea with the largest output and sales volume at present. Black tea is a kind of fully fermented tea, which is made from suitable new shoots of tea trees and refined through withering, rolling, fermentation, drying and other processes. It contains rich carrot Vitamin A, calcium, phosphorus and other inorganic elements and a variety of amino acids, and has a unique taste. Black tea not only quenches thirst and refreshes the mind, but also has good effects such as promoting body fluid and clearing heat, anti-inflammatory and sterilizing, strengthening bones and stretching blood vessels, making it very popular in the international market. [0003] The production cycle of black tea is from summer to autumn. Due to the influence of environmental factors, the general black tea production...
