Embodiment 1

[0019] A method for preparing organic green tea. It is commonly known as the first tea at the time of the first tea picking around Qingming every year. As the saying goes, the first tea is fragrant and the second tea is sweet. The Mingqian tea on the market is the first tea. Picking tea is just picking new buds. Tea picking requirements: picking new tea should be as tender as possible, generally no more than three tender leaves are better. Don't pinch your nails when picking, but break them. Pick it well and install it in a bamboo basket. Generally you need to pick two or three catties of fresh leaves to make. Then the picked tea leaves are carried out using the following process: sequentially including (1) a greening step, (2) a rolling step and (3) a drying step.

[0020] (1) In the curing step, firstly, the tea leaves after being cooled are blanched in hot water at 85℃-92℃ for 1-2 minutes, then taken out and dried; then the dried tea leaves are sent to the drum curing machi...

Embodiment 2

[0024] A method for preparing organic green tea, which sequentially includes (1) a greening step, (2) a rolling step, and (3) a drying step;

[0025] (1) The curing step, firstly, the tea leaves after being cooled are blanched in hot water at 85°C-92°C for 1 minute, then removed and dried; then the dried tea leaves are sent to the drum curing machine, and the tea leaves are quenched by high-temperature hot air. , The temperature in the drum is maintained at 145°C, and the curing time is 40 seconds; then the microwave is used for curing, the tea leaves are cooled in the drum for 3-5 minutes, and then the tea leaves are sent to the microwave curing device for 1.5-2 minutes.

[0026] (2) In the rolling step, the tea leaves after the rollers are put into the tea box of the rolling device, the tea leaves in the tea box are rubbed by the kneading plate, and 50℃-80℃ is passed into the tea box during the rubbing process. Water vapor; kneading time 5-10 minutes; the specific method is to pr...

Embodiment 3

[0029] A method for preparing organic green tea, which sequentially includes (1) a greening step, (2) a rolling step, and (3) a drying step;

[0030] (1) The curing step, firstly, the tea leaves after being cooled are blanched in hot water at 85°C-92°C for 1 minute, then removed and dried; then the dried tea leaves are sent to the drum curing machine, and the tea leaves are quenched by high-temperature hot air. , The temperature in the drum is maintained at 145°C, and the curing time is 40 seconds; then the microwave is used for curing, the tea leaves are cooled in the drum for 3-5 minutes, and then the tea leaves are sent to the microwave curing device for 1.5-2 minutes.

[0031] (2) Kneading step, sending the tea leaves after the drum has been cured into the tea box of the kneading device, using the kneading plate to knead the tea leaves in the tea box, and passing 60℃-65℃ into the tea box during the kneading process Water vapor; kneading time 5-8 minutes; the specific method is ...
