Description

Technical Field

[0001] This utility model relates to the field of coffee bean grinding, specifically to a high-efficiency coffee bean grinding device. Background Technology

[0002] Coffee beans refer to the fruit of the plant used to make coffee. Broadly speaking, there are two types of coffee beans in the world: Arabica beans and Robusta beans. The coffee fruit consists of two oval seeds facing each other, with a flat connecting surface, called a flat bean. However, there are also beans composed of a single round seed, called a round bean. Their taste is the same. To allow people to enjoy the flavor of coffee, they typically grind the beans into coffee powder. By grinding the powder to different coarseness, different flavors of coffee can be brewed. Grinding coffee beans requires a grinding device. Existing grinding devices can only grind coffee beans once, resulting in insufficient grinding efficiency. If the ground coffee powder does not reach the desired coarseness, it needs to be poured back into the grinding device for further grinding, which is cumbersome.
