Pemetikan daun segar tidak hanya berkaitan dengan kualitas, hasil, dan ekonomi manfaat teh jadi, tetapi juga untuk pertumbuhan dan kehidupan ekonomi pohon teh. Oleh karena itu, dalam proses produksi teh, dilakukan pemetikan teh segar sangat penting, dan pemetikan harus tepat waktu.

Teh Cina Petani memiliki pepatah bahwa panen tiga hari lebih awal adalah harta, dan tiga hari panen terlambat adalah rumput. Artinya, daun teh harus dipetik waktu. Teh jadi yang dihasilkan dari daun awal berkualitas tinggi, dan teh Semakin lama teh segar dibuat, semakin buruk kualitas teh jadi. Di Selain itu, pemetikan tepat waktu dapat mempromosikan perkecambahan tepat waktu daun teh baru, mempersingkat interval, sangat meningkatkan frekuensi memetik teh, mencapai efek peningkatan produksi dan pendapatan, dan juga dapat mengurangi hama dan penyakit daun teh.

Menurutnya.

1. Teh yang. dipilih dengan tangan

Teh yang dipilih dengan tangan adalah metode paling tradisional untuk memetik daun segar. Memilih dengan tangan harus dilakukan, dan memilih teh segar satu per satu secara spearately, bukan untuk meraih semuanya dengan tangan.

Keuntungan: Standar daun teh disatukan (misalnya, hanya tunas yang dipetik, dan hanya satu tunas dan dua daun yang dipetik), yang mudah dipahami.

Kekurangan: memakan waktu dan melelahkan, biaya pengambilan teh tinggi. Jika area taman teh besar, sulit untuk memilih waktu.

There are usually three kinds of withering methods, natural withering, withering on the withering rack, withering machine withering

 

1. Natural withering

Spread out the tea leaves on the ground (need to lay a layer of plastic cloth, etc. to prevent tea leaves from directly contacting the ground). This method is the most primitive and the simplest method. Advantages: save money, less trouble, hardly need any input, about 2.5 kg/㎡ of tea leaves can be placed Disadvantage: It is only suitable for the production of small batches of tea. If large quantities of tea leaves are produced, the required space is very large; if it encounters rainy weather, it can only be placed in the room to wither.

2. Withering on the withering rack

 

Place the fresh leaves on the withering racks, each withering rack has 20 layers, and each layer has a whole bamboo sieve tray. There are mesh holes on the sieve tray to facilitate air flow. At the same time, bamboo strips can absorb water, increase the rate of water evaporation, and accelerate the speed of tea leaves withering. Advantage: Small footprint; each withering tray can hold 2.5 kg of fresh leaves, and each shelf (about 1.2 square meters) can hold 50 kg of fresh leaves, which greatly saves space; at the same time, the withering tray is made of bamboo, which is clean, hygienic and environmentally friendly . There is a pulley at the bottom of the machine, which makes it easier to move.

3. Withering machine withering

Put the fresh leaves on the withering machine. The withering machine can place 40 kg of tea leaves per square meter. The machine can blow air from the bottom of the tea leaves, which can adjust the temperature of the wind, greatly increasing the withering speed of the tea leaves. Advantages: Small area, hot air can be blown in, greatly improved the withering speed (efficiency increased by about 70%) Disadvantages: The machine needs to be heated, the power is about 15kw, and it needs to be connected to a 380V power supply.

Shaking and withering are both parts of the fermentation. During the withering process of oolong tea, because the leaves are calmly placed, a lot of water will only evaporate from the leaves, and the water in the leaf stalks is not lost, which will lead to the bitterness of the tea leaves is very strong, which seriously affects the quality of oolong tea. It is necessary to shake. Through the shaking process, the activity of the leaves is enhanced. The water in the leaf stalks continues to be transported to the leaves, allowing the leaves to re-evaporate the water, Distribute the grassy smell of tea leaves, so that the taste of the finished oolong tea will not very bitter, greatly improving the quality of oolong tea.

The shaking methods of oolong tea,there are three common: hand shaking,  shaking machine, hor air tea leaf shaking machine

 

  1. Hand shaking

The hand-made round sieve is a round shaker tool with a small grid screen woven by bamboo craftsmen. The hand-made round sieve shaking can make the fresh leaves of tea leaves move up and down in the sieve. Jumping  left and right, and roll. Making the weak tea leaves like freshly picked tea leaves, let the fresh leaves of the tea leaves frement deeply again, and promote tea formation of excellent quality of oolong tea such as fragrance.There are some small grid on the sieve, when processing, it will filter out debris such as tea residue. Advantages and Disadvantages: This is the most primitive processing technology, and also a processing tool favored by tea masters. However, due to the small output, manual processing is very tiring, and it is gradually replaced by a mechanized shaker.

  1. Shaking machine

The shaking drum is made of pure natural top layer bamboo skin, which is environmentally friendly and will not damage the tea leaves. Moreover, the shaking drum has small holes to filter out the debris falling on the leaves and play a cleaning role. The machine is equipped with a speed-adjusting device, which can adjust the speed of shaking, and a time control system is added. When the time is up, it automatically stops working. It is convenient to operate and saves time and effort. It is one of the indispensable equipment for high-end oolong tea production.

  1. Hor air tea leaf shaking machine

The hot air tea leaf tossing machine is one of the important equipment for producing high-end oolong tea. The drum is punched with galvanized plate, which is beautiful and generous. You can also choose all stainless steel plates for more sanitation and environmental protection. Through a highly integrated intelligent control panel, the speed, temperature, processing time, etc. can be adjusted, and heating can be selected from electric heating or wood and charcoal heating. Through the rotation and heating of the machine, the moisture in the tea leaves can be evenly distributed, while slowly fermenting, so that the taste of the finished tea is more fragrant. With the heating furnace, different wood or charcoal is used, which can make the tea have the aroma of different wood, and the flavor of the finished tea is unique! Different from ordinary traditional tea, let your tea sales be higher and better.

The step of fixation is mainly used for the production of various unfermented or semi-fermented teas. The activity of the enzyme in the fresh leaves is reduced by high temperature, the tea polyphenols in the fresh leaves are stopped for oxidative fermentation, and the odor of the grass is removed, the aroma of the tea leaves is excited, and the moisture in the fresh leaves is evaporated. The fresh leaves become softer, which is conducive to the subsequent rolling process, and the tea leaves are not easily damaged.

After fixation, the green tea need to be cooled. Let the temperature of the tea leaves lower and distribute moisture to prevent high-temperature moisture from smothering tea.

When tea fixation, pay attention to "young leaves with high temperature and faster, old leaves with lower temperature and slower", which means that the young leaves need high temperature to fixation quickly, killing the enzymes in the tea faster, while fixation for a short time, will not damage the tea. Old leaves need to fixation at low temperature and slow speed. The leaves of old leaves are thicker, if high temperature is used, the heat cannot be transferred to the inside. The leaves on the outside are scorched and the leaves on the inside are not yet cooked. Such tea leaves are useless.

Tea fixation is also known as , Tea Steaming, Tea Roasting .etc, although the names are different, but the functions are the same. The most mainstream fixation method currently uses roasting fixaion process, which makes the tea taste more fragrant.

The method of tea fixation, the common ones are steam fixation, roasting fixation, hot wind fixation
