As described above, in the present invention, the upper and lower cylinders are arranged so that they can fluid-tightly face each other through a filter paper that moves intermittently between the upper and lower cylinders, each of which has a piston inside, and is preferably preheated. The extraction liquid is pumped into the grinding cylinder along with a certain amount of hot water in the upper cylinder, or the extracted liquid is pumped into the upper cylinder by the action of both pistons, and then into the lower cylinder by the action of both pistons. The coffee extract is taken out of the lower cylinder, and the extracted coffee powder is discharged out of the upper cylinder along with the filter paper that moves as the upper and lower cylinders separate. The machine also has the advantage of being able to extract regular coffee every time it is sold, producing the same delicious coffee as if it were brewed professionally, and having a simple configuration and simple operation sequence.
