Example Embodiment

[0019] Example 1

[0020] The quick yellowing method of yellow tea includes the following steps:

[0021] (1) Material selection: picking the tender shoots of one bud, one leaf and two leaves, and fresh tea leaves that are sturdy, free from diseases and insect pests, and without mechanical damage as raw materials;

[0022] (2) Spreading: Place the selected fresh leaves on the spreading equipment, the spreading thickness is 2~3cm, and the spreading amount is 2kg / m 2 , The spreading temperature is 27℃, the relative humidity is 60%, and the spreading time is 2h;

[0023] (3) Desalination: hot-air de-destructing the leaves after spreading. The hot-air inlet temperature is 350℃, and the moisture content after de-creing is controlled at about 60%;

[0024] (4) Twisting: After the leaves are cooled and re-moisturized, they will be twisted. The twisting time is 30 minutes. Light pressing for 10 minutes, heavy pressing for 10 minutes, and no pressure for 10 minutes will cause the tea leaves to r...

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.
