[0002] Coffee is a beverage that people often drink in their daily lives. The emergence of coffee bean grinding machines allows people to easily get fresh coffee. Traditional coffee bean grinding machines grind coffee beans into coffee powder through a grinding mechanism. When the coffee powder passes through the powder outlet channel, it will adhere to the inner wall of the channel. Although there is little coffee powder remaining in the powder outlet channel, it is particularly inconvenient to clean the coffee powder remaining in the powder outlet channel, which will cause the taste to cross when changing to other flavors of coffee beans. In addition, the residual powder left in the channel for too long can easily lead to food safety hazards such as mold, taste change, and deterioration.
