Why do the first steps of all kinds of tea have to wither?

Because the freshly picked tea leaves have more moisture and the grass smell is heavier, they need to beplaced in a cool and ventilated room for withering. After withering, the water content of the tea leaves isreduced, the leaves become soft, and the grassy smell disappears. and the aroma of the tea leaves isrevealed, which is conducive to subsequent processing, such as fixation, twisting, fermentation, etc. The color,taste, and quality of the green tea are made are better than tea without withering.

3 type different withering methods of tea withering

There are usually three kinds of withering methods, natural withering, withering on the witheringrack, 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.
