There was a problem in that it required a lot of manpower. Furthermore, since 6 to 10 cups of coffee are usually extracted at once, if there is any leftover coffee left for 2 to 3 hours, oxidation progresses due to contact with air and the taste deteriorates. Furthermore, when coffee raw material manufacturers wholesale coffee raw materials to restaurants, they are required to vary the strength and amount of coffee depending on the type of coffee in order to ensure the taste quality of the coffee. With such a coffee server, the strength and amount of coffee would change each time it was poured, making it impossible to maintain consistent coffee quality at restaurants.

In view of the above-mentioned problems, the present invention has been developed to further automate the process by mixing water and a concentrated beverage extracted from a concentrated beverage (coffee) storage device in a quantitative manner, and by making the settings variable with a single touch using a memory card. The purpose of the present invention is to provide a concentrated beverage dispensing device that can maintain a constant concentration of beverages.
