Problems solved by technology

[0004] 1) The withering time is too long; the hot air withering time of this scheme is 22-26 hours. Withering is to control the water content of the tea leaves to make them suitable for rolling and fermentation, and reduce the amount of water that must be evaporated during baking. , the withering time is too long and the degree of withering is not easy to control, which affects the subsequent processing of tea leaves
[0005] 2) The kneading time is too long; the kneading time of this scheme is 85-95 minutes. In order to achieve a relatively high cell crushing rate, the kneading time is prolonged, which increases the processing time of the whole tea and reduces the production efficiency

Abstract

The invention discloses a method for making black tea, which comprises the following steps: withering of fresh leaves, rolling, fermenting, cooling down, drying and refrigerating. This method is easy to control the degree of withering, and the rolling time is short, which improves the production efficiency of tea leaves, and the prepared black tea has tight and thin strands, dark and lustrous color, full of luster, with the fragrance of green grass, bright leaf bottom, good quality and easy to brew. The color of the tea soup produced is red and bright, which is another good choice for the production method of tea drinks.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a method for making black tea. Background technique [0002] Tea is one of the more popular drinks in the market. It not only tastes good and smells fragrant, but also contains many nutritional and medicinal ingredients. Tea has become an important variety of beverages in the world from China to the world. With the improvement of people's living standards With continuous improvement, the competition in the tea market is becoming increasingly fierce. China has a long history of tea production, vast tea areas, different natural conditions, a wide variety of tea trees, and different harvesting and processing methods, thus forming a variety of tea products in various poses and with different expressions. Through long-term practice, people have created and adopted different processing methods, developed a series of different teas from non-fermented, semi-fermented to fully fer...
