Raw dark green tea and production process thereof

Abstract

The invention relates to raw dark green tea and a production process thereof. The production process comprises the following steps: picking fresh leaves from tea trees; conducting enzyme deactivationwith a cylinder to obtain enzyme-deactivated tea; placing the enzyme-deactivated tea in a twisting machine for twisting the tea according to the principle of "light-heavy-light" and obtaining twistedtea; conducting pile fermentation on the twisted tea, completing pile fermentation to obtain pile-fermented tea when water droplets appear on the surface of tea base, tea leaves changes from dark green to yellowish brown, and tea masses become less viscous and can be scattered by beating; scattering and deblocking the pile-fermented tea in order to prevent the tea from being hardened and caked, and then obtaining deblocked tea; drying the deblocked tea to obtain dried tea; aggregating the dried tea and conducting secondary piling and secondary fermentation to obtained piled tea; and drying thepiled tea to obtain the raw dark green tea. According to the invention, the fermentation twice are used to adjust degree of fermentation; and the deblocking process is added to scatter the hardened tea leaves at the first time and prevent presence of masses in the raw dark green tea materials, thereby facilitating the control of product quality.

Description

technical field [0001] The invention belongs to the field of tea, and in particular relates to black hair tea and a production process thereof. Background technique [0002] Heimao tea is prepared from the fresh leaves of tea tree varieties suitable for Anhua black tea, such as Anhua Yuntaishan big leaf species, Quan Yeqi, and Anhua group species. [0003] The production process of traditional black hair tea is rough, and the difference between high-grade raw materials and low-grade raw materials is not distinguished. If the traditional black hair tea production process is followed, the following defects will be caused: [0004] 1. The processing technology of high-grade raw materials and low-grade raw materials is not distinguished, resulting in unstable quality of black hair tea; [0005] 2. Using one-time stacking process, it is likely to cause quality deterioration of tea during the stacking process. If the fermentation is excessive, it will produce a sour taste, and if...

AI Technical Summary

Problems solved by technology

[0003] The production process of traditional black hair tea is rough, and the difference between high-grade raw materials and low-grade raw materials is not distinguished. If the traditional black hair tea production process is followed, the following defects will be caused:

[0004] 1. The processing technology of high-grade raw materials and low-grade raw materials is not distinguished, resulting in unstable quality of black hair tea;

[0005] 2. Using one-time stacking process, it is likely to cause quality deterioration of tea during the stacking process. If the fermentation is excessive, it will produce a sour taste, and if the fermentation is too light, it will not be able to meet the quality and style requirements of black tea;

[0006] 3. The heaping process is easy to cause the tea leaves to agglomerate. According to the traditional black-mao tea production process, the hei-mao tea will be dried immediately after being piled, which will cause a lot of tea lumps in the black-mao tea, which will affect the quality of the black-mao tea

[0007] The combination of the above defects will lead to a decline in the sensory evaluation of black hair tea
