[0002] Tea baking is a crucial link in tea making process, and its purpose is to remove the moisture inside tea through heat treatment, adjust the texture and flavor of tea, and make it more mellow.

[0003] A common and simple way of baking tea is to add tea into an iron pot after preheating treatment, and use a wooden or iron shovel to continuously stir the tea to prevent the tea from sticking to the pot or being burnt. During the frying process, the tea is stirred from the bottom of the pot, and the stirring action should be uniform and forceful to prevent the tea from sticking to the pot or being burnt. According to the condition of the tea, the fire power should be appropriately increased to speed up the frying of the tea, but at the same time, the control of the fire power should be paid attention to to avoid over-frying. The frying time is adjusted according to different tea types and frying requirements. Generally, the frying time of light baking tea is about several minutes, the frying time of medium baking tea is about tens of minutes, and the frying time of heavy baking tea can be extended to several tens of minutes. At the same time, attention should be paid to the change of the color of the tea to master the appropriate frying degree.
