Description

Technical Field

[0001] The utility model relates to the field of coffee bean grinding devices, in particular to a coffee bean grinding device for making coffee. Background Art

[0002] Coffee beans come from the fruits of the coffee tree. Coffee beans usually need to be roasted before they can become hot drinks. The roasting process will change the color, aroma and flavor of the beans. From light roasting to dark roasting, the taste characteristics of coffee will be affected to varying degrees. Coffee beans are the raw materials for making coffee drinks. After grinding, they can be brewed or extracted to make a variety of different flavors of coffee, such as Americano, latte, espresso, etc.

[0003] However, the existing coffee bean grinding device has a relatively complex internal structure and mainly relies on extrusion grinding to grind coffee beans into coffee bean particles. The coarseness of the coffee bean particles is usually determined by the grinding time. This requires professional baristas to control the appropriate grinding time to achieve a grinding coarseness within a suitable range. Once the coffee bean particles are coarser, water will easily flow through the coffee beans during extraction, resulting in a faster extraction speed; while finer coffee bean particles make it more difficult for water to pass through, resulting in a slower extraction speed, which directly affects the types and contents of solutes extracted from the coffee.
