The present invention relates to an espresso machine. More specifically, the present invention relates to an automatic feeding reservoir system for espresso machines for extracting espresso from ground bean flour after automatic grinding and roasting and storing the beans for a certain period of time.

Espresso is commonly referred to as a very dark Italian coffee and is popularly used because it extracts in a short time at a high pressure and has a small amount of caffeine and can feel the pure taste of coffee.

These espresso are divided into cafe espresso, solo, and faro rungo. Caffe espresso refers to a pure espresso with nothing added, and a solo refers to a cup of espresso and two cups of espresso. Rongo refers to the long-lived espresso.

In addition, espresso lentreto refers to what was picked at the moment when it was extracted the darkest, which is thicker than cafe espresso. Espresso Regular or Espresso Americano is a kind of hot water poured into an espresso, which is a little bit darker than Americano.

On the other hand, espresso is generally extracted by a dedicated machine called an espresso machine. For example, the espresso machine extracts 30 ml of coffee within 20 seconds at a pressure of about 9 atm and a temperature of about 90 ° C. And the beans need to be finely trimmed three times as compared to using a drip type machine.

Here, such an espresso machine is specifically disclosed in (Patent Document 1), and will be described with reference to the following.

According to the espresso coffee extracting apparatus of the related art, when coffee particles are supplied to a two-way cylinder through a coffee grinder, the extracting piston descends, And a two-way cylinder driving part for continuously extracting espresso through the coffee extracting filter part while moving left and right when the extracting piston driving part is lifted up and discharging the extracted debris to the outside have.

Here, factors that determine the taste of espresso include the thickness and quantity of bean, pressure, falling speed and ripening period. In other words, after roasting, carbon dioxide emanating from the beans and bean maturing are matured for a certain period of time, so that the taste and aroma of espresso can be enjoyed.

However, in the espresso machine according to the prior art including the patent document 1, the espresso is extracted after aging the beans for a certain period of time, but the roasted beans are directly extracted after grinding without aging the beans. When extracted, the volume of the bean flour can be increased by carbon dioxide, which can act as a factor to break the espresso machine.
