Abstract
A brewer system includes a storage tank, a brew chamber movable relative to the storage tank and positioned over a mouth of the storage tank, and a filter tape positioned between the chamber and the storage tank. Brewing substance and water are added to the chamber to form a brewed beverage. The brewed beverage passes through the filter tape and into the storage tank through the mouth.
Claims8
A brewer system comprising:
- a storage tank formed to define a mouth communicating with the storage tank;
- a filter tape extending over the mouth of the storage tank and movable relative to the storage tank;
- a brew chamber movable relative to the storage tank, the brew chamber configured to retain the filter tape over the mouth and to form a seal around the mouth;
- a brewing substance delivery system configured to dispense brewing substance into the brew chamber;
- a water delivery system configured to deliver water into the brew chamber to mix with the brewing substance and form a brewed beverage;
- a pressure control system coupled to the brew chamber configured to pressurize the storage tank with a gas such that the gas passes through the mouth into the brew chamber to agitate the water and brewing substance during formation of the brewed beverage, wherein the pressure control system is configured to pressurize the brew chamber to force the brewed beverage from the brew chamber through the filter tape and mouth into the storage tank;
- a controller coupled to the brewing substance delivery system, the water delivery system, and the pressure control system, and wherein the controller is configured to operate the brewing substance delivery system, the water delivery system, and the pressure control system at the selection of a user;
- and
- a sensor coupled to the controller and configured to provide a signal to the controller to shut off the pressure control system when a pressure in the brew chamber drops.

A method of forming a brewed beverage from a brewing substance, the method comprising:
- selectively positioning a filter tape over a mouth of a storage tank, the mouth communicating with the storage tank;
- selectively positioning a brew chamber relative to the storage tank to retain the filter tape over the mouth and form a seal around the mouth of the storage tank;
- selectively delivering water and brewing substance to the brew chamber to form a volume of brewed beverage;
- selectively pressurizing the brew chamber with a pressure control system to force brewed beverage from the brew chamber through the mouth into the storage tank;
- sensing when a pressure in the brew chamber drops;
- and
- shutting off the pressure control system when the pressure drops.
