Description

Technical Field

[0001] The utility model relates to the technical field of coffee machines, in particular to a coffee machine powder pressing device. Background Art

[0002] A coffee tamper is a tool used in the coffee making process to compact the coffee grounds. When making coffee drinks like espresso, the degree of compaction of the coffee grounds plays a crucial role in the extraction quality of the coffee.

[0003] The powder cups in existing coffee tamping devices are mostly stamped from stainless steel, resulting in a simple structure. Once the coffee powder is packed and compacted, a gap forms between the inner ring of the cup and the grounds, leaving the grounds loose in the middle of the bottom. This results in varying densities of the grounds at the bottom of the cup. When brewing coffee, high-pressure steam preferentially passes through the looser, larger gaps in the grounds, reducing extraction efficiency. Furthermore, the high-pressure steam can blow the grounds up and clog the steam outlet of the coffee machine. Utility Model Content
