Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a manual coffee press. Background Art

[0002] The extraction of Italian coffee requires hot water to be subjected to a certain air pressure so that it can pass through the compacted coffee powder and extract coffee liquid that is approximately twice the weight of the coffee powder. The surface of the freshly extracted coffee liquid needs to have a CREMA layer filled with gas and oil.
