Abstract
Temperature control for extracted beverages, including coffee, via controlled vacuum, and associated systems and methods are shown. A representative system includes a brew chamber, a beverage chamber in fluid communication with the brew chamber, a vacuum source in fluid communication with the beverage chamber, and a flow control device positioned to vary the force applied by the vacuum chamber on the brew chamber via the beverage chamber.
Claims23
A beverage brewing system, comprising:
- a brew chamber;
- a beverage chamber in fluid communication with the brew chamber;
- a vacuum source in fluid communication with the beverage chamber;
- and
- a flow control device positioned to vary, among multiple non-zero values, the force applied by the vacuum source the brew chamber via the beverage chamber wherein the flow control device is configured to vary the force applied by the vacuum source on the brew chamber via the beverage chamber over the course of extracting a volume of beverage from the brew chamber.
2 more elements
A beverage brewing system, comprising:
- a hot water source;
- a brew chamber coupled to the hot water source to receive hot water, the brew chamber having:
- a support positioned to receive coffee grounds,
- a first beverage port, and
- a filter positioned to at least restrict the passage of coffee grounds from the brew chamber through the first beverage port;
- a beverage chamber having lower surface, with a second beverage port and a vacuum port positioned in the lower surface;
- a beverage flow path coupled between the first and second beverage ports to direct coffee from the brew chamber into the beverage chamber, the beverage flow path having an upright portion and an inverted portion within the beverage chamber, the inverted portion having a beverage exit opening positioned to direct coffee downwardly toward the lower surface;
- a vacuum source;
- a vacuum flow path coupled between the vacuum source and the vacuum port of the beverage chamber, the vacuum flow path having an upright portion and a vacuum entrance opening within the beverage chamber;
- and
- a flow control device coupled between the vacuum source and the vacuum entrance opening to vary the force applied by the vacuum source on the brew chamber via the beverage chamber.
8 more elements
A beverage brewing system, comprising:
- a brew chamber;
- a beverage chamber;
- a beverage flow path coupled between the brew chamber and the beverage chamber and having an exit positioned to direct a beverage into the beverage chamber;
- a pressure differential device operatively coupled to at least one of the brew chamber or the beverage chamber;
- and
- a flow straightener positioned along the beverage flow path, the flow straightener having multiple, parallel, axially extending flow channels positioned proximate to the exit of the beverage flow path.
3 more elements
A beverage brewing system, comprising:
- a brew chamber;
- a beverage chamber in fluid communication with the brew chamber;
- a vacuum source in fluid communication with the beverage chamber;
- a first flow control device positioned to vary the force applied by the vacuum source on the brew chamber via the beverage chamber;
- and
- a second flow control device including a flow straightener.
3 more elements
A beverage brewing system, comprising:
- a brew chamber;
- a beverage chamber in fluid communication with the brew chamber;
- a vacuum source in fluid communication with the beverage chamber;
- and
- a flow control device positioned to vary the force applied by the vacuum source on the brew chamber via the beverage chamber, wherein in a first configuration, the flow control device produces a laminar, continuous flow of beverage from the brew chamber into the beverage chamber, and wherein in a second configuration, the flow control device produces a spray or a discontinuous turbulent flow of beverage from the brew chamber into the beverage chamber.
2 more elements
A beverage brewing system, comprising:
- a brew chamber having a lower surface;
- a beverage chamber having a lower surface and in fluid communication with the brew chamber via a beverage flow path extending through the lower surface of the brew chamber and upwardly through the lower surface of the beverage chamber;
- a vacuum source in fluid communication with the beverage chamber;
- and
- a flow control device positioned to vary the force applied by the vacuum source on the brew chamber via the beverage chamber.
2 more elements
A beverage brewing system, comprising:
- a brew chamber;
- a beverage chamber in fluid communication with the brew chamber;
- a vacuum source in fluid communication with the beverage chamber;
- and a flow control device positioned to vary, among multiple non-zero values and over the course of extracting a volume of coffee from the brew chamber, the force applied by the vacuum source on the brew chamber via the beverage chamber.
