Problems solved by technology

The traditional alcoholization method mainly relies on the slow aging process of natural conditions, the production cycle is long, and the conditions are not easy to control
At present, the existing alcoholization equipment is mainly for microwave heating treatment or near-infrared auxiliary heating treatment for the finished raw tea. This method can only improve the aroma of the tea, but often has an adverse effect on the color and soup color.

Embodiment

[0014] Embodiment A kind of fast aging processing method of tealeaves, comprises the following steps:

[0015] (1) classify the fresh tea leaves to remove non-tea impurities, then wither and spread the fresh tea leaves until the water content of the withered leaves is 70-75%;

[0016] (2) After the above-mentioned withering treatment, carry out the de-enzyme treatment, then carry out the moisture regain treatment, carry out the kneading treatment with the green tea leaves after the moisture regain treatment, and finally carry out the secondary drying of the tea leaves processed by kneading, and the moisture content of the tea leaves after drying is 18- 25%;

[0017] (3) Transfer the above-mentioned processed tea leaves to a refrigerated high-pressure processor, use pure water with a temperature of 18-25°C as the cooling and pressure transmission medium, and boost the pressure at a boosting speed of 180-240MPa / min. After reaching 600-900MPa, keep it for 5-15min, and then quick...

Abstract

The invention discloses a fast aging processing method for tea. The method includes the steps of: (1) subjecting fresh tea to grading treatment to remove non tea impurities, and then conducting withering spreading on fresh tea till a water content of 70-75%; (2) conducting deactivation treatment on the withering treated tea, then performing moisture regain treatment, subjecting the moisture regain treated tea leaves to rolling treatment, and finally carrying out secondary drying on the rolled tea leaves to a water content of 18-25%; (3) transferring the treated tea into a refrigeration high-pressure processor, adopting 18-25DEG C purified water as the cooling and pressure transmitting medium, conducting pressure raising at a speed of 180-240MPa / min to 600-900MPa, then maintaining the state for 5-15min, and then conducting quick pressure relief; and (4) aging the obtained tea at 22-36DEG C for 4-6h, controlling the spreading thickness at 8-14cm, and at the end of aging, treating the tea to a water content of less than 10%, thus obtaining a finished product.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a rapid aging processing method for tea. Background technique [0002] Fresh tea leaves need to be processed through multiple processes to form drinkable tea leaves. Since fresh tea leaves contain many substances that have beneficial or adverse effects on color, aroma, and taste, such as tea polyphenols, caffeine, amino acids, etc., how to reduce bitterness, improve freshness, reduce grassy smell, and improve aroma has become an important issue. A very important issue in the process of tea processing. The aging of tea is the process of blending, improving and improving the sensory quality of tea. The traditional alcoholization method mainly relies on the slow aging process of natural conditions, the production cycle is long, and the conditions are not easy to control. At present, the existing alcoholization equipment is mainly for microwave heating treatment or near-inf...
