Embodiment 1

[0019] The production process of the pressed black tea of ​​the present embodiment is as follows:

[0020] The first step is the selection of raw materials. The fresh leaves of the "Two Pools and One Village" tea tree in Shihegang Township, Xinyang City, Henan Province are selected as raw materials;

[0021] The second step is air separation to remove impurities, using air separation machine to remove old leaves, remaining leaves and other impurities in fresh leaf raw materials;

[0022] The third step is freezing treatment. Put the raw materials of fresh leaves into -20 ℃ cold storage for 1 hour, so that the fresh leaves of tea trees will freeze at low temperature, and the cells will burst. When the tea leaves are intact, polyphenol oxidase and tea Full exposure to polyphenols;

[0023] The fourth step is stacking and fermentation, put the fresh leaf raw materials with fully broken cells into the black tea fermentation room at 30°C, and ferment for 3 hours;

[0024] The fif...

Abstract

The invention discloses a production process of compacted black tea, wherein the production method comprises the following steps: picking fresh tea tree leaves and removing impurities by air selection; putting the fresh tea tree leaves into a low temperature refrigeration house with the temperature of -20 DEG C, and promoting cell damage of the fresh tea tree leaves; putting the fresh tea tree leaves having cells fully broken into a fermentation chamber, and accumulating and fermenting; primarily drying the fermented tea leaves till the dryness is 60%, then loading the tea leaves into a pressmold, and pressing into a tea blank with fixed shape; and after the tea blank after compressing is no longer deformed, rebaking at low temperature until the tea blank is fully dried, and thus obtaining the finished product. The compacted black tea prepared by the method has the advantages of compact and uniform shape, dark color and luster, lasting flower fragrance, bright red soup color, mellow taste and complete leaf base. The tea product has the effects of diminishing inflammation, killing bacteria, removing toxin, refreshing oneself and removing fatigue, inducing diuresis, promoting secretion of saliva or body fluid, clearing heat, preventing caries, strengthening and nourishing stomach, promoting digestion, stimulating appetite, delaying aging, lowering blood pressure, lowering bloodsugar, lowering blood lipid, resisting cancer, resisting radiation, preventing and treating myocardial infarction and the like.

Description

technical field [0001] The invention relates to the technical field of tea primary processing and reprocessing, in particular to a production process of tightly pressed black tea. Background technique [0002] Historically, Xinyang City only produced green teas such as Xinyang Maojian tea and stir-fried green tea. The structure of the tea was single, while summer and autumn green tea tasted bitter, poor in quality, difficult to be accepted by the market, low in price, and poor in economic benefits. A large amount of tea resources are wasted, and its economic value has not been brought into full play. In 2010, the Xinyang Municipal Party Committee and the Municipal Government proposed that based on the rich tea resources in Xinyang City, while protecting and enriching the golden signboard of "Xinyang Maojian" green tea, adjust the structure of tea products and vigorously develop and produce black tea. Since the spring of 2010, Xinyang City has started to develop and produce ...
