Apparatus for making and dispensing nitrogen-charged coffee

摘要

A method of making coffee is provided. After a cold-brewed coffee is extracted from coffee beans, nitrogen gas is charged into the cold-brewed coffee. The cold-brewed coffee into which nitrogen gas is dissolved, is cooled to form a nitrogen-charged coffee. Therefore, the nitrogen-charged coffee may keep a rich density of foam and a flavor.

主权项

1. An apparatus of making coffee comprising:
a keg storing a cold-brewed coffee; a nitrogen tank containing nitrogen gas, the nitrogen tank being connected with keg by a first line to be configured to provide nitrogen gas with the keg to form a nitrogen-charged coffee; a discharging unit being connected with the keg by a second line to be configured to discharge the nitrogen-charged coffee; a first cooling unit covering the second line to be configured to cool the nitrogen-charged coffee; and a third line connecting the nitrogen tank with the discharge unit; wherein the discharging unit is configured to selectively open/close the second line and the third line to selectively discharge the nitrogen-charged coffee or to discharge the nitrogen-charged coffee and nitrogen gas at the same time.
