Abstract

A beverage supplying apparatus that supplies a beverage into a beverage container, includes: an ingredient storage unit to store a beverage ingredient; a compressed gas supplying means to supply compressed gas to the ingredient storage unit and pressurize the beverage ingredient; and a beverage supplying means to, when receiving a supply command, allow the pressurized beverage ingredient to be supplied to a nozzle, and supply compressed nitrogen gas to the nozzle, so that the nitrogen gas and the beverage ingredient are mixed and stirred at the nozzle and the beverage is discharged to the beverage container through the nozzle.

First claim

What is claimed is:

1. A beverage supplying apparatus that supplies a beverage into a beverage container, the beverage supplying apparatus comprising:
an ingredient storage unit configured to store a beverage ingredient;
a compressed gas supplying means configured to supply compressed gas to the ingredient storage unit and pressurize the beverage ingredient; and
a beverage supplying means having a nozzle and configured to, when receiving a supply command,
allow the pressurized beverage ingredient to be supplied to the nozzle, and
supply compressed nitrogen gas to the nozzle, so that the nitrogen gas and the beverage ingredient are mixed and stirred at the nozzle creating a nitrogen gas containing extracted beverage which is discharged to the beverage container through the nozzle,

wherein the nozzle includes a beverage orifice extending along a vertical direction, depressurizing the nitrogen gas containing extracted beverage and jetting out the depressurized nitrogen gas containing extracted beverage downward from a lower end exit of the beverage orifice, and a collision wall provided to face the lower end exit so that the nitrogen gas containing extracted beverage, jetted out from the lower end exit, collides with the collision wall and is dispersed in a horizontal direction and dropped down to a discharge port.

2. The beverage supplying apparatus according to claim 1 , further comprising:
a cooling means configured to cool the beverage ingredient supplied to the nozzle from the ingredient storage unit.

3. The beverage supplying apparatus according to claim 1 , wherein the compressed gas supplying means is configured to supply the compressed nitrogen gas to the ingredient storage unit.

4. The beverage supplying apparatus according to claim 1 , wherein the nozzle causes the nitrogen gas, having been supplied to the nozzle, to be mixed and stirred with the beverage ingredient while causing the nitrogen gas to swirl along an inner wall surface of the nozzle.

5. The beverage supplying apparatus according to claim 1 , wherein the beverage ingredient is a cold temperature extracted beverage that has been extracted from water and ground coffee beans.

6. The beverage supplying apparatus according to claim 1 , wherein the nozzle further includes a mixing unit, from which the beverage orifice extends downwardly, for mixing the beverage ingredient and the compressed nitrogen gas, the beverage ingredient and the compressed nitrogen gas mixed in the mixing unit being ejected through the beverage orifice.

7. The beverage supplying apparatus according to claim 1 , wherein the collision wall is spaced from the lower end exit of the beverage orifice so that the beverage ingredient and the compressed gas ejected from the lower end exit collide with the collision wall.
