Apparatus for making brewed coffee and the like
An apparatus for brewing ground, brewable foodstuffs having a water reservoir, a boiler, and a flow meter all connected in a common fluid path with a pump that produces a fluid pressure in the common fluid path. A pod holder capable of receiving a pod formed of filter material and containing a mass of ground, brewable foodstuffs having a sieved bottom is located so as to receive the metered volume of water from the common fluid path. In turn, an interchangeable or pivotally mounted fluid conduit is positioned to receive fluid passing through the sieved bottom and to convey the fluid into one or more cups. With this apparatus a small quantity of a brewed liquid, such as coffee, can be produced in a relatively short brewing period with a pleasing taste profile. The fluid pressure may also be adjusted so as to enhance the creation of a crema layer in a coffee drink.
1 . An apparatus for brewing ground, brewable foodstuffs, the apparatus comprising:
a water reservoir having an output;
a boiler; and
a plurality of interchangeable pod holder assemblies, each pod holder assembly comprising a pod holder capable of receiving a pod formed of filter material and containing a mass of ground, brewable foodstuffs, the pod holder having a sieved bottom, and a fluid conduit positioned to receive fluid passing through the sieved bottom and to convey the fluid into one or more cups;
wherein the boiler and the water reservoir are connected in a common fluid path with a pump that produces a fluid pressure in the common fluid path and wherein the fluid path begins at the output of the water reservoir and the pod holder is located so as to receive the metered volume of water from the common fluid path.
2 . The invention according to claim 1 further comprising a circuit for controlling the fluid pressure produced by the pump.
3 . The invention according to claim 2 wherein the fluid pressure produced by the pump is based on user selection of one of at least two discrete pressures.
4 . The invention according to claim 1 further comprising a second circuit controlling the fluid pressure produced by the pump.
5 . The invention according to claim 4 wherein the fluid pressure produced by the pump is based on user selection of one of at least two discrete pressures.
6 . The invention according to claim 1 wherein the water reservoir is selectively removable from the common fluid path, the water reservoir further including a valve selectively sealing the output of the water reservoir.
7 . The invention according to claim 1 further comprising a pod, the pod including:
a selected mass of ground, brewable foodstuffs,
a filter material surrounding the selected mass of ground, brewable foodstuffs,
wherein the selected mass of ground, brewable foodstuffs and the filter material form a pie-shaped unit.
8 . The invention according to claim 7 wherein the selected mass of ground, brewable foodstuffs is in the range of approximately 9.3 grams to 9.9 grams.
9 . The invention according to claim 8 wherein the filter material includes a planar top sheet and a substantially cup shaped bottom sheet wherein the top and bottom sheets are adhered together.
10 . The invention according to claim 9 wherein the bottom sheet circumscribes a diameter of approximately 47.5 millimeters and a height of approximately 13 millimeters.
11 . The invention according to claim 1 wherein the relative length of one or more of said fluid conduits is preselected by a user based on a height of said one or more cups.
12 . The invention according to claim 1 wherein at least one of said interchangeable pod holder assemblies is selected by a user based on a particular ground, brewable foodstuff to be brewed.
13 . The invention according to claim 1 further comprising a a flow meter providing a metered volume of water.
14 . The invention according to claim 13 wherein the flow meter is further connected with the boiler and the water reservoir in said common fluid path with the pump.
15 . The invention according to claim 14 further comprising a circuit for controlling the metered fluid output of the flow meter based on user selection of one of at least two discrete volumes.
16 . The invention according to claim 1 wherein at least a portion of one or more of said interchangeable pod holders includes an indicia of distinction.
17 . The invention according to claim 16 wherein said indicia of distinction is either a descriptive label or a color.
18 . A method of brewing ground, brewable foodstuffs comprising:
selecting one of a plurality of pod holder assemblies;
placing a pod containing ground, brewable foodstuffs into a pod holder;
pumping a metered volume of water at a selected fluid pressure;
heating the metered volume of water;
feeding the heated metered volume of water at the selected fluid pressure to the pod in the pod holder resulting in a fluid having a desired amount of soluble solids; and
passing the fluid having a desired amount of soluble solids into a cup.
