The temperature of 85 ℃ is more than or equal to T3 and less than or equal to 92 ℃, and the scheme of the embodiment can set the temperature of T3 to 88 ℃.
In an exemplary embodiment of the present application, too high or too low of the extraction water temperature may result in over-extraction or under-extraction of coffee, both of which may result in a poor mouthfeel of the resulting coffee. According to the scheme of the embodiment, the water temperature near the water inlet of the cavity is tested through the temperature sensor, when the water temperature reaches T3 ℃, the water inlet is opened to feed water into the grinding cavity, the water temperature in contact with coffee powder is ensured to be within the optimal extraction temperature range, and the coffee sourness and the foreign flavor are reduced.
