Problems solved by technology

[0002] In recent years, the tea beverage industry has developed very rapidly, and the demand for tea raw materials dedicated to beverages is also very large. Generally, green tea and black tea are the main ingredients. However, traditional green tea raw materials have problems such as unstable soup color and taste, which have consistently plagued tea beverages. industry; while yellow tea has the characteristics of bright yellow and stable soup, mellow taste, etc., but the production scale is small, the production cost is high, and the appearance characteristics are not suitable for extraction operations in the tea beverage industry.

Embodiment 1

[0020] Embodiment 1: a kind of processing method of special-purpose yellow tea for beverage

[0021] 1) Pick the tender shoots of middle-leaf tea trees with one bud and one leaf to one bud and three leaves, place them on the tea withering machine and spread them thinly to 5cm, blow them with the wind at 28°C for 1 hour, let them stand for 2 hours, and circulate them until the tea leaves are fresh Moisture content 72%;

[0022] 2) Kill the fresh leaves treated in step 1) with a drum-type greening machine. The conditions of the drum-type greening machine are that the outer wall temperature of the drum feeding end is 270-280°C, the inner wall temperature is 195-210°C, the middle outer wall temperature is 250-270°C, and the end wall temperature is 250-270°C. The temperature of the outer wall is 230-250°C, the time for fresh tea leaves to pass through the drum is 170s, the green leaves have no green smell, and the water content is 64%;

[0023] 3) Put the green leaves obtained in ...

Abstract

The invention discloses a processing method of special yellow tea for beverages, and belongs to the technical field of tea processing. The processing method of the special yellow tea for beverages comprises the following steps: performing withering treatment on tea leaves; carrying out fixation treatment; carrying out heap-yellowing treatment; carrying out rolling and cutting treatment by using arotor-type rolling and cutting machine; carrying out rolling and cutting treatment by using a CTC tea rolling and cutting machine; carrying out drying treatment by using a vibrating fluidized bed drying machine; carrying out alcoholization treatment; and carrying out drying treatment by using the vibrating fluidized bed drying machine. The processing method of the special yellow tea for beveragestakes tender tips of tea trees with medium-sized leaves which are rich in contents and mellow in flavor as a raw material; and innovations are made on yellow tea processing technology so as to preparefresh tea leaves into yellow tea that is yellow, bright and stable in soup color, mellow in flavor as well as convenient for extracting or mechanical packaging instead of bag-packaging in the beverage industry. Thus, the problems of tea soup stability of traditional yellow tea, green tea and black tea in the tea beverage industry are solved; moreover, the fluidized bed drying process is adopted,so that the phenomena of tea leakage through air holes of linking boards of common chain-plate automatic drying machines and blowing of tea granules out of the drying machines by hot air are avoided.

Description

technical field [0001] The invention belongs to the technical field of tea processing, and in particular relates to a processing method of special yellow tea for beverages. Background technique [0002] In recent years, the tea beverage industry has developed very rapidly, and the demand for tea raw materials dedicated to beverages is also very large. Generally, green tea and black tea are the main ingredients. However, traditional green tea raw materials have problems such as unstable soup color and taste, which have consistently plagued tea beverages. industry; and yellow tea has the characteristics of bright yellow and stable soup, mellow taste, etc., but the production scale is small, the production cost is high, and the appearance characteristics are not suitable for extraction operations in the tea beverage industry. Therefore, be badly in need of a kind of processing method of special-purpose yellow tea for beverage, to solve the problems referred to above. Contents...
