One, tea can be divided into the following description:, Picking tea leaves by steam treatment, causes the oxidation of the enzyme to stop, keeping green tea color and remove the blue astringent (steam made from unfermented tea, green tea)Second, using sunlight or standing room for the steps (wilt), and percentages according to the demand to determine the degree of fermentation (lightly fermented withering 8-10 hours, fermentation is withering in 9-15 hours, fermentation is withering 15-20 hours. Universal classification of tea, tea manufacturing process, the tea leaf oxidation takes place much as respectively. Tea of oxidation role also called tea of fermentation, is tea in the group main of phenol class compounds, catechin pigment class (catechins), after more phenol oxidation enzyme of catalytic Hou occurred oxidation, formed oxidation form of more phenol class polymer, as tea yellow quality (theaflavins), and tea red quality (thearubigins), oxidation of degree more high, more phenol class polymer of formed and type on more more. Catechins are colorless compounds, double combination (Dimer) tea yellow quality as an orange-yellow compound, larger polymers (polymer) reddish-brown tea red mass is soluble in water, so manufacturing occurs during the oxidation of the more dramatic types of tea, such as black or deep fermentation of oolong, tea water more near the orange-red color. Puer tea of dark brown color, from microbes fermentation process for another type of mode.Three, fried cyanine variety of raw materials, according to the tea-Ching season collapsed, fermentation process, adjusting procedures to set the temperature and time, FRY aims to stop tea-Ching Ching material changes during the fermentation process, time and temperature (temperature 200~300 ° c), time (6-10 minutes)Four, rolling is the use of pressure and friction, while oppression while rubbing, damaged tea tissue content components easier to soak, and hope that the uniformity of the water can.Of five, will be rolled into the dry winds also exert pressure and rubbing, making tea while loosened while drying (rubs), similar to a pendulum shaking machinery to make it repeat a similar manual rubbing action, and allowed to dry (fine rubbing). (Dry for the first time)Six tea, after the above steps, to long-term preservation and enhance its flavor, integer steps will, again with hot-air dryers to dry until moisture for drying steps around 5% (drying).Seven, rejects tea from the tea buds, stems, floating leaves, powder, called filtering.
