Description

Technical Field

[0001] The utility model relates to the technical field of coffee grinding, in particular to a high-speed and convenient grinding device for a coffee machine. Background Art

[0002] A coffee machine is a machine that automatically brews coffee. People apply electronic technology to coffee machines, realizing automatic control of the entire process of brewing coffee, such as grinding, pressing, filling, brewing, and removing residues, and creating coffee machines. Grinding is crucial for coffee extraction. It can be said that the different coarseness of coffee grinding directly affects the flavor of a cup of coffee, and the coarseness of coffee grinding directly affects the length of extraction time and the extraction rate. The finer the coffee is ground, the denser the powder layer is, and there are more coffee powder particles in contact with hot water, which increases the extraction resistance, and it is easier to extend the extraction time and improve the extraction rate, and it is easy to over-extract. The grinding device in the coffee machine usually cuts the coffee raw materials by rotating the cutting and grinding knives and then grinds them, so that the coffee raw materials can be directly and quickly ground. However, due to its direct grinding, the coffee raw materials are accumulated in one place, and the cutting and grinding knives cannot ensure that the coffee powder they grind is relatively uniform, thereby affecting the grinding quality of coffee. For this reason, we propose a high-speed and convenient grinding device for coffee machines. Utility Model Content
