Beverage dispenser outlet and a method of preparing a beverage with same
View Patent ↗A beverage dispenser, including a whipper disk and a dispensing spout connected downstream to the housing for dispensing the whipped beverage mixture. A sieve is disposed within the dispensing spout and is configured for reducing the number of large bubbles present within the fluid over a predetermined size. An output plate covers a downstream end of the dispensing spout and has a plurality of holes formed therein for reducing the velocity of the whipped beverage mixture through the dispensing spout.
1. A beverage dispenser, comprising:
a whipper configured for flowing a liquid beverage mixture therethrough and for whipping a beverage mixture to produce a crema;
a dispensing spout connected downstream of the whipper for dispensing the whipped beverage mixture;
a first filter element disposed within the dispensing spout configured for preparing small bubbles by reducing the number of large bubbles present within the fluid that are greater than a predetermined size; and
a second filter element covering a downstream end of the dispensing spout and having a plurality of holes formed therein for reducing the velocity of the whipped beverage mixture through the dispensing spout;
wherein the holes of the second filter element are larger than the size of the small bubbles generated by the first element so that a crema of the small bubbles is dispensed.
2. A beverage dispenser, comprising:
a whipper configured for flowing a liquid beverage mixture therethrough and for whipping a beverage mixture to produce a crema;
a dispensing spout connected downstream of the whipper for dispensing the whipped beverage mixture;
a first filter element disposed within the dispensing spout configured for preparing small bubbles by reducing the number of large bubbles present within the fluid that are greater than a predetermined size; and
a second filter element covering a downstream end of the dispensing spout and having a plurality of holes formed therein for reducing the velocity of the whipped beverage mixture through the dispensing spout, wherein the first filter element is a sieve having a first plurality of holes formed therein, and wherein the second filter element is an output plate having a second plurality of holes formed therein, the first plurality of holes being smaller in size than the second plurality of holes.
3. The dispenser of claim 2 , wherein the output plate and the sieve are spaced to form a void between the bottom surface of the sieve and the upper surface of the output plate, and wherein the dispensing spout is configured to permit access to the space therebetween to a user.
4. The dispenser of claim 3 , wherein the output plate is moveable away from the downstream end of the dispensing spout to permit access to the void between the output plate and the sieve.
5. The dispenser of claim 4 , wherein the sieve is affixed within the dispensing spout.
6. The dispenser of claim 3 , wherein the output plate is affixed to the dispensing spout by a hinge that permits the output plate to be selectively positioned to cover the downstream end of the dispensing spout and such that the output plate is moveable away from the downstream end of the dispensing spout.
7. The dispenser of claim 6 , wherein the output plate includes a clip configured to maintain the output plate in a position so as to cover the downstream end of the dispensing spout.
8. The dispenser of claim 3 , wherein the output plate is removably affixed to the dispensing spout.
9. The dispenser of claim 8 , wherein the output plate is removably affixed to the dispensing spout in a press-fit association.
10. The dispenser of claim 3 , further comprising a secondary inlet in fluid communication with the dispensing spout such that the liquid beverage mixture from the whipper will not flow through the secondary inlet during normal operating conditions, and wherein the sieve is removable from the dispensing spout through the secondary inlet.
11. The dispenser of claim 10 , wherein the sieve has an extension affixed thereto having a proximal end that is positioned proximate to the secondary inlet and configured to permit a user to grasp the proximal end to aid in removing the sieve from the dispensing spout.
12. The dispenser of claim 11 , wherein the extension includes a number of radially-extending wings to maintain a desired position of the sieve within the dispensing spout.
13. The dispenser of claim 12 , further including a cap removably affixable to the secondary inlet and configured to abut the proximal end of the extension to maintain a desired position of the sieve within the dispensing spout.
14. The dispenser of claim 13 , wherein an inlet extension associated with the cap additionally functions as a secondary inlet in fluid communication with the dispensing spout and configured for receiving a fluid from a fluid source that feeds both the mixing chamber and the secondary inlet.
15. The beverage dispenser of claim 2 , wherein the output plate is removably affixed to the dispensing spout to permit the output plate to be selectively positioned to cover the downstream end of the dispensing spout but such that the output plate is moveable away from the downstream end of the dispensing spout to allow cleaning of the dispensing spout.
16. A method for preparing a beverage having a high-quality crema, which comprises introducing a beverage mixture into the whipper of the beverage dispenser of claim 14 ; whipping the beverage mixture; and dispensing a beverage having a crema from the dispenser.
17. A method for preparing a beverage having a high-quality crema, which comprises introducing a beverage mixture into the whipper of the beverage dispenser of claim 15 ; whipping the beverage mixture; and dispensing a beverage having a crema from the dispenser spout.
