After pouring the tea leaves, the tea leaves are soaked in water. The temperature sensor 107 detects and controls the temperature of the extraction box 1 to ensure that the temperature in the extraction box 1 is maintained in a suitable temperature atmosphere.
[0021] See also Figure 3-4In this embodiment, the stirring assembly 200 includes a motor 201, a rotating shaft 202, a stirring blade 203, a movable plate 204, and a discharge pipe 205.
