연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

An embodiment of a machine for brewing a beverage such as coffee includes a chamber and a piston assembly disposed in the chamber. The chamber is operable to receive a liquid such as water and a flavor base such as ground coffee, and to allow the beverage to brew from a mixture of the liquid and the base. The piston assembly is operable to filter a solid such as spent coffee grounds from the brewed beverage by moving in a first direction, and to force the filtered beverage out of the chamber by moving in a second direction. By modifying or automating some or all steps of the French press brewing technique, such a machine may control one or more of the brewing parameters with a level of precision that yields brewed coffee having a uniform taste from cup to cup. Furthermore, such a machine may brew the coffee with a speed that renders the machine suitable for use by establishments that serve significant amounts of coffee.

1. A machine for brewing a beverage, the machine comprising: a chamber operable to receive a liquid and a flavor base and to allow the beverage to brew; anda piston assembly disposed within the chamber and operable to: filter a solid from the brewed beverage by moving in a first direction; andforce the filtered beverage out of the chamber by moving in a second direction, wherein the piston assembly comprises: a filter assembly; anda valve that is operable to: allow the brewed beverage to pass through the filter assembly as the piston assembly moves in the first direction; andprevent the filtered beverage from passing through the filter assembly as the piston assembly moves in the second direction,wherein the chamber has a bottom and a beverage-dispensing conduit disposed in the bottom; the piston assembly moves away from the chamber bottom while moving in the first direction; and the piston assembly moves toward the chamber bottom while moving in the second direction. 2. The machine of claim 1, further comprising a controller operable to control the movement of the piston assembly. 3. The machine of claim 1 wherein the chamber and the piston assembly are cylindrical. 4. The machine of claim 1 wherein: the chamber has an end and a beverage-dispensing conduit disposed in the end;the piston assembly moves away from the chamber end while moving in the first direction; andthe piston assembly moves toward the chamber end while moving in the second direction. 5. The machine of claim 1 wherein: the flavor base comprises coffee grounds;the liquid comprises water; andthe solid comprises spent coffee grounds. 6. The machine of claim 1 wherein the piston assembly comprises a filter assembly that is operable to: filter the flavor base from the brewed beverage by passing the brewed beverage from a first portion of the chamber on a first side of the piston assembly to a second portion of the chamber on a second side of piston assembly and by preventing passage of the solid from the first chamber portion to the second chamber portion as the piston assembly moves in the first direction; anddispense the filtered beverage by preventing passage of the filtered beverage from the second chamber portion to the first chamber portion as the piston assembly moves in the second direction. 7. The machine of claim 1, further comprising a reservoir operable to hold the liquid, to heat the liquid to a predetermined temperature, and to provide the heated liquid to the chamber. 8. The machine of claim 1, further comprising: a reservoir operable to hold the liquid and to heat the liquid to a first predetermined temperature; anda temperature-control unit operable to receive the heated liquid from the reservoir, to change the temperature of the liquid from the first predetermined temperature to a second predetermined temperature, and to provide the liquid having the second predetermined temperature to the chamber. 9. The machine of claim 1, further comprising: a reservoir operable to hold the liquid and to heat the liquid to a first predetermined temperature; anda temperature-control unit operable to receive the heated liquid from the reservoir, to cool the liquid to a second predetermined temperature, and to provide the cooled liquid to the chamber. 10. The machine of claim 1, further comprising: wherein the chamber has an opening;a substantially flat surface contiguous with the opening; andwherein the piston assembly has a surface and is operable to move into a wipe position where the piston-assembly surface is substantially coplanar with the contiguous surface. 11. The machine of claim 1, further comprising: wherein the chamber has an opening;a substantially flat surface contiguous with the opening;wherein the piston assembly has a surface; andwherein after forcing the beverage out of the chamber the piston assembly is operable to move into a wipe position where the piston-assembly surface is substantially coplanar with the contiguous surface. 12. The machine of claim 1, further comprising: wherein the chamber has an opening;a substantially flat surface contiguous with the opening;wherein the piston assembly has a surface; andwherein after filtering the beverage but before forcing the beverage out of the chamber the piston assembly is operable to move into a wipe position where the piston-assembly surface is substantially coplanar with the contiguous surface. 13. The machine of claim 1, further comprising: wherein the chamber has an opening; anda nozzle disposed outside of the chamber adjacent to the opening and operable to provide the liquid to the chamber. 14. The machine of claim 1, further comprising: wherein the chamber has a wall; andan opening in the chamber wall operable to provide the liquid to the chamber. 15. The machine of claim 1 wherein the second direction is opposite to the first direction. 16. A machine for brewing a beverage, the machine comprising: a chamber operable to receive a liquid and a flavor base and to allow the beverage to brew; anda piston assembly disposed within the chamber and operable to: filter a solid from the brewed beverage by moving in a first direction; andforce the filtered beverage out of the chamber by moving in a second direction, wherein the piston assembly comprises: a filter assembly; anda valve that is operable to: allow the brewed beverage to pass through the filter assembly as the piston assembly moves in the first direction; andprevent the filtered beverage from passing through the filter assembly as the piston assembly moves in the second direction;a holder operable to hold a beverage cup; andwherein the piston assembly is operable to dispense the beverage into the cup. 17. A machine for brewing a beverage, the machine comprising: a chamber operable to receive a liquid and a flavor base and to allow the beverage to brew; anda piston assembly disposed within the chamber and operable to: filter a solid from the brewed beverage by moving in a first direction; andforce the filtered beverage out of the chamber by moving in a second direction, wherein the piston assembly comprises:a filter assembly; anda valve that is operable to: allow the brewed beverage to pass through the filter assembly as the piston assembly moves in the first direction; andprevent the filtered beverage from passing through the filter assembly as the piston assembly moves in the second direction;a holder operable to hold a beverage cup;a sensor operable to indicate whether the beverage cup is in the holder; andwherein the piston assembly is operable to force the beverage out of the chamber and into the beverage cup if the sensor indicates that the cup is in the holder. 18. A machine for brewing a beverage, the machine comprising: a chamber operable to receive a liquid and a flavor base and to allow the beverage to brew, wherein the chamber has a wall;a piston assembly disposed within the chamber and operable to: filter a solid from the brewed beverage by moving in a first direction; andforce the filtered beverage out of the chamber by moving in a second direction; anda heating assembly coupled to the wall and operable to maintain the wall at a predetermined temperature.
