Description

Non-compact type but flower Fu brick tea and forming system thereof

Technical Field

The invention belongs to the technical field of tea production, and particularly relates to a preparation method and a preparation system of golden flower Fuzhuan tea.

Background

Golden flower, as its name suggests, is golden in color and is shaped like a flower. In particular to a plurality of golden small granular substances in Fuzhuan tea. It is believed that this is an aggregate of the golden sporocysts of a fungus. The bacterium is currently named as Eurotium cristatum in the market. The eurotium cristatum grows more vigorously in tea, particularly in Fuzhuan tea, because the acid pH condition of tea juice is just the best condition for growth and reproduction of golden flowers, and particularly green tea, black tea and black tea are high-quality materials for growing flowers.

The golden flower is an enzyme bacterium beneficial to human beings. The golden flower can secrete amylase and oxidase, can catalyze the conversion of protein and starch in the tea into monosaccharide, catalyze the oxidation of polyphenol compounds, and convert the polyphenol compounds into substances beneficial to human bodies, so that the characteristics of the tea, such as taste and the like, are improved and optimized. For example, the original Hunan Anhua black tea Fuzhuan tea is purposely cultivated with a 'eurotium cristatum' community in the manufacturing process, which needs a very unique processing technology to manufacture. Even, the research of adding eurotium cristatum to improve the health care effect of some products in the health care industry begins, so that the trend and the demand of the industry are also for how to collect eurotium cristatum in tea leaves, the eurotium cristatum cultured by adopting a culture medium has similar health care effect, but the formation of 'eurotium cristatum' bacterial colony without obvious discrimination of unique fragrance of tea leaves is influenced by temperature, humidity, gas, compactness, time, pH and tea juice, and the effect and the efficiency are different.

In the prior art, the black tea blossom is mainly the loose tea blossom and the brick tea blossom. The compressed brick tea is prepared, and the earliest black tea is inconvenient to transport and difficult to transport at the moment because the black tea is transported to the northwest, so that the volume of the black tea needs to be reduced, and the black tea is steamed and pressed into blocks which are convenient to carry and store; meanwhile, the tea brick can keep the aroma for a longer time. The characteristic that the black tea pursues 'older and more fragrant' is seen, the collection of the black tea is more beneficial to the aging of the quality, and a more ideal effect can be achieved in a shorter time. However, when the brick tea is made in the previous stage, the flowering period is long, the effect is difficult to guarantee, and during the golden flower cultivation, the flowering condition cannot be observed from the inside, so that core burning and mildewing are easily caused; when in storage, the food is compacted; the tea body has high density and is difficult to meet the conditions of oxygen, humidity, temperature and the like required by the growth of eurotium cristatum; the tea is difficult to take in the later stage, and even special tools are needed to take the tea. The tea leaves are bloomed, the gimmick is more than the actual meaning, the tea leaves are not favorable for storage and transportation, the tea leaves are not extruded, the effect of eurotium cristatum on the whole tea leaves is poor in catalytic effect, the fragrance of the tea leaves is not rich and pure, and the characteristic of being more old and more fragrant cannot be achieved; and the loose tea is not beneficial to the collection of the golden flower.

Based on the problems, the applicant develops a preparation method of the golden flower fu brick tea, the non-compact brick tea is prepared by low-pressure compaction, the flowering efficiency is high, and the golden flowers are rich and luxuriant and are convenient to collect.
