Problems solved by technology

[0003] At present, the quality of Shihua green tea is uneven, and the processing technology mainly has the following problems: 1. The selection of fresh leaf varieties is messy; 2. The lack of precise control of temperature in the production process; 3. Too much pursuit of shape in the production process, And shorten the production time as much as possible, so that the ingredients in the tea leaves cannot be fully transformed. Some products do not have the aroma and taste that Shihua green tea should have.

Embodiment 1

[0034] A kind of processing method of novel Mengdingshan stone flower green tea, comprises the steps:

[0035] 1) Picking of fresh leaves: Picking the young buds and leaves mainly of the local Mengshan "Liuyezhong" tea tree variety, the standard is single bud or one bud and one leaf.

[0036] 2) Withering: Spread the fresh leaves on the dustpan in time after entering the factory, and the thickness of the spread leaves is 1.5cm. Put the dustpan on the drying rack and push it into the air-conditioned withering room for withering. The withering temperature is controlled at about 22°C, and the air humidity is controlled at 65%. The upper and lower dustpans are exchanged every hour, so that the moisture of the withered leaves can be evenly lost.

[0037] 3) Finishing: adopt 6CST060 type roller fixing machine to finish, the fixing temperature is 320~350°C, the speed of fixing machine is 45 rpm, and the time for the fixing leaves to stay in the drum is 2min. After the greening is c...

Embodiment 2

[0049] Among the quality components of tea, the content of tea polyphenols, catechins, free amino acids and caffeine are relatively high. These four components are closely related to the quality of tea and flavor quality, and to a considerable extent determine and affect the "color, aroma, Taste" and other qualities. The content of tea water extracts reflects the concentration of tea soup and is a comprehensive indicator that characterizes the overall level of tea taste components. A high content of water extracts indicates that tea tastes are rich in substances, which is an important material basis for tea taste "rich" and "resistance to brewing" [1] . The free amino acid content is high, the taste is fresh and mellow, the aroma is high and long, and the quality is relatively excellent. Tea polyphenols are the substances with the most content in tea, and are the main substances that form the bitter taste of tea. Free amino acids are important components of tea soup, and the ...
