The basic processing flow of three cups of tea is: sharing green – fixing green – rubbing – baking two green – frying three green – boiling pot – finishing with wool tea.
1. Fix the principle of “killing youth at high temperatures, first and then low, old leaves and old leaves, and old leaves and tender killsâ€.
Fixing temperature: The temperature of the air inside the 20-tube cylinder is 120-130. When C starts to vote.
Casting amount: According to the size of the drum, the degree of raw and tender materials, the level of moisture content flexibility.
Fixing time: depending on the length of the drum and the degree of raw materials and tenderness, the level of water content is determined, generally 1 to 4 minutes.
Fixing degree: The leaf color changes from bright green to dark green, without red stems and red leaves, soft hand-kneading, slightly sticky, stalks folded and constantly, tightly pinched leaves can be grouped, slightly elastic, Qingcao gas loss, slightly tea Fragrant, killing the leaf weight reduction rate of about 40% is moderate.
When using the blower to cool the cylinder, cool it quickly and spread it in a timely manner. Avoid accumulation.
2. The volume of rubbing and rubbing leaves may vary depending on the type of rubbing machine, usually 15 to 75 kg.
Knead pressure is light, heavy and light alternately.
The rubbing time is determined by the degree of killing the young leaves and fixing the green leaves, generally 30 to 50 minutes is appropriate.
The degree of rubbing is controlled by hand rubbing and rubbing leaves have a sticky feel, the leaf tissue breaking rate reaches 45 to 65%, and the rate of sticking reaches over 80%.
The mass of the rubbing leaf is sieved with a deblocking sieve, and the thick strips are rubbed again.
3, bake two green bake two blue using high temperature fast drying method, air temperature of about 95 ~ 115 °C is appropriate.
Stalles thickness about 2cm.
The time varies depending on the thickness of the dryer and the stalls, and is generally 8 to 12 minutes.
Bake two degrees of green: the leaves are not sticky, hand-kneading is still slightly able to clump, after loosening the hand to be able to loosen, moisture content in the 40 ~ 45% bake, thin booth heat regain.
4, fried three green pot temperature 100 °C or so.
The amount of leaf is about 15kg. There are a few parts of the tea bars that are fried and squeezed. However, they are constantly shattered and poked. There is still elastic force. When the moisture content is about 20%, the pan will recover.
5, the amount of pot pot depends on the size of the bottle fry machine, generally about 25 ~ 60kg.
Pot temperature 90-100. C, master the first high and low, slightly higher before the pan.
Stir fry until the knot tight, dry (ie, moisture content 5-6%), pan out timely cool.
6, Maocha finishing According to the quality of each level of three cups of Maomao tea, through screening, picking tick, winnowing, make up the fire Titian, uniform packing boxes and other processes, and then re-processing, in order to achieve the quality of commodity tea requirements.
Three cups of incense processing
Fresh leaves processing three cups of fragrant tea should come from the pollution-free tea plantation in Taishun and be purchased in strict accordance with standards. It is not advisable to purchase fresh leaves that contain adulterated tea, non-tea materials, and inferior quality.
