chinese green tea operation points

Shangrao browed processing technology
    The processing sub-browed Shangrao crank, rolled, bar manager, four drying processes.
    1, fixing a 30-or 40-cylinder crank machine. chinese green tea operating points: first, start running about 25 minutes warm-up space, so the cylinder temperature of 120 ℃ or so, you can cast leaves, leaf weight just started to vote more appropriate, so as not to scorch shoots, leaf mass when fixing up requirements, the amount of investment must remain stable leaves uniform, make sure to kill shoots cooked thoroughly to kill, kill the uniform. Fixing an appropriate standard: full dull leaves, leaves soft, fold stems continue, grass gas disappears, slight fragrance, no focal point edge explosion, shoots complete. Fixing time for 1.5min, fixing about 35% weight loss. A time when leaves open the hair dryer, thermal cooling, to keep the emerald green tea.
    2, a 30 rolled rolled rolled machine type or 25 type, 25 type cast leaves does not exceed 2.5kg, 30 leaf-type cast does not exceed 4kg, rolled pressure principle to light, anti-tea overflow cut, color and degree of dark, rolling time according to Yin Hao browed, White-browed Tippy, three grades of raw materials Laonen browed Verde extent, lies in between 2 ~ 5min.
    3, the rationale for structured management of the vibration of the machine can be used, the pot is about 120 ℃ temperature control at the time about 10 minutes, until the barbed feel the touch of tea when Pekoe began to fly, to the tea stalls cool.
    4, after drying the tea stalls of cool reason 20min ~ 30min, then the use of china green tea dryer for drying, drying and re-drying points twice early to bake, bake the beginning of drying temperature of 130 ℃ to 80% dry, by sharing cool 30min then re-bake. Re-drying temperature is controlled at 100 ℃ or so required, tie guan yin prevent the fire temperature is too high and dry too fast, the aroma is not high, mm color yellow. Drying to below 6% moisture content of tea, hand-twisted into powder, spread cool before packing storage.
