Processing method of ball-shaped green tea

Abstract

The invention provides a processing method of ball-shaped green tea. The processing method comprises the following steps of (1) picking fresh green tea; (2) cleaning the picked green tea with microbubbles and ultrasonic waves; (3) putting the cleaned tea leaves in a vacuum centrifuge, and performing spin-drying; (4) putting the dried tea leaves in a rolling fixation machine, and performing fixation; (5) performing freezing: rapidly freezing the tea leaves after fixation to minus 15 to minus 5 DEG C; (6) putting the green tea after fixation in a rolling cylinder of a rolling machine, and performing soft rolling; (7) performing high-speed centrifugation on the green tea of which the surface temperature is 15-20 DEG C, after primary rolling, through the vacuum centrifuge; (8) rolling the green tea after centrifugation once again; and (9) drying the green tea shaped through rolling for the first time and drying the dried green tea for the second time. The cleaned green tea is rapidly treated through a vacuum spin dryer, so that redundant moisture can be rapidly removed; and the green tea after primary rolling is subjected to centrifugation, so that internal substances of the green ten can sufficiently immerse into the surface layers of the tea leaves, the rolling efficiency and the rolling quality are improved, and the mouth feel is aromatic.

Description

technical field [0001] The invention belongs to the technical field of greening processing, and in particular relates to a method for processing lump-shaped green tea. Background technique [0002] Green tea refers to the tea made from the new leaves of the tea tree, without fermentation, through typical processes such as killing greens, rolling, and drying. The color of the dry tea and the brewed tea soup and the bottom of the leaves are mainly green, hence the name green tea. Modern scientific research has confirmed that green tea does contain biochemical components that are closely related to human health. It has pharmacological effects such as dysentery and dehumidification, and also has certain pharmacological effects on modern diseases, such as radiation sickness, cardiovascular and cerebrovascular diseases, and cancer.

Problems solved by technology

[0003] In the current green tea processing process, the picked green tea is not cleaned cleanly, which will affect the taste of green tea, so it takes a certain amount of time to soak or add baking soda to clean, and the cleaned green tea needs to be spread out in the shade to dry, which takes a long time and is efficient Low, easy to affect the integrity of tea
