Problems solved by technology

However, the above-mentioned yellow tea processing technology is too complicated, the labor cost is too high, the material selection is limited, resulting in low output, the price naturally skyrockets, and the produced yellow tea tends to be "only green but not yellow", which cannot be quantified on a large scale Production

Embodiment 1

[0020] The method for the rapid dull yellowing of yellow tea specifically comprises the following steps:

[0021] (1) Material selection: pick fresh tea leaves with one bud and one and two leaves, and fresh tea leaves that are fat, free from diseases and insect pests, and without mechanical damage;

[0022] (2) Spreading: Place the selected fresh leaves on the spreading equipment, the spreading thickness is 2-3cm, and the amount of spreading leaves is 2kg / m 2 , the spreading temperature is 27°C, the relative humidity is 60%, and the spreading time is 2 hours;

[0023] (3) Finishing: the leaves after spreading are carried out hot air finishing, the hot air inlet temperature is 350°C, and the water content after finishing is controlled at about 60%;

[0024] (4) Kneading: Knead the leaves after cooling and regaining moisture. The kneading time is 30 minutes, wherein, light pressure is 10 minutes, heavy pressure is 10 minutes, and no pressure is 10 minutes. The cell fragmentati...

Embodiment 2

[0032] The method for the rapid dull yellowing of yellow tea specifically comprises the following steps:

[0033] (1) Material selection: pick fresh tea leaves with one bud and one and two leaves, and fresh tea leaves that are fat, free from diseases and insect pests, and without mechanical damage;

[0034] (2) Spreading: Place the selected fresh leaves on the spreading equipment, the spreading thickness is 2-3cm, and the amount of spreading leaves is 2kg / m 2 , the spreading temperature is 20-30°C, the relative humidity is 70%, and the spreading time is 2 hours;

[0035] (3) Finishing: the leaves after spreading are carried out hot air finishing, the hot air inlet temperature is 300°C, and the water content after finishing is controlled at about 45%;

[0036] (4) Kneading: the leaves after finishing are cooled and regained moisture and then kneaded. During kneading, light pressure, heavy pressure and non-pressurized kneading are carried out successively until the tea leaves h...

Abstract

The invention discloses a method for quick heap-yellowing of yellow tea. Heap-yellowing is conducted by means of a totally sealed rotary roller container, the massic volume ratio of a placed wet tea base to the roller container is 1:10-40, the temperature of the interior of the roller container is maintained at 25-80 DEG C, the roller container is rotated once every other 0.5-4 h to enable tea to be stirred, and heap-yellowing is stopped after the wet tea base appears evenly orange or golden. By conducting heap-yellowing on yellow tea at a constant temperature with the totally sealed rotary roller container and reserving certain space in the roller container, tea leaves can yellow quickly and can also be stirred, so that tea leaves can yellow more evenly; stirring is conducted once every once in a while during heap-yellowing, so that yellow tea obtained through heap-yellowing does not have soggy odor. By the adoption of the heap-yellowing method, time for heap-yellowing of yellow tea can be shortened remarkably, stirring is easier during heap-yellowing, the quality of yellow tea is improved, labor is saved, and continuous production is facilitated.

Description

technical field [0001] The invention belongs to the field of tea processing, and in particular relates to a method for quick yellowing of yellow tea. Background technique [0002] Yellow tea is one of the six traditional teas in my country. According to the tenderness, it can be divided into three types: big yellow tea, small yellow tea and yellow bud tea. The quality characteristics of the "three yellows" of "bottom yellow" make it a unique quality style. The soup is apricot yellow and the taste is mellow. It is recommended by tea experts as the most suitable tea for drinking. Chinese yellow tea is distributed throughout the north and south of the river. The famous ones are Mengding Huangya in Mingshan County, Sichuan Province, Huoshan Huangya in Huoshan County, Anhui Province, Pingyang Huangtang in Pingyang County, Zhejiang Province, Guangdong Dayeqing in Guangdong Province, Luyuan Tea in Yuan’an County in Hubei Province, and Yueyang in Hunan Province.
