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, Kafe, Webinar 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.

Coffee makers with features for rapid and/or multiple extraction processes, and associated systems and methods, are shown. A representative method for brewing coffee includes placing ground coffee on a filter element of a brew chamber, directing heated water into the brew chamber and in contact with the ground coffee and, during a first phase, brewing coffee in the brew chamber without subjecting the coffee to a pressure differential of at least 150 torr between the brew chamber and a coffee chamber to which the brew chamber is coupled, the coffee chamber having a capacity of 200 mL or more. The representative method further includes, during a second phase, extracting the coffee from the brew chamber through the filter element and into the coffee chamber via a pressure differential of at least 150 torr between the brew chamber and the coffee chamber.

1. A coffee brewing system, comprising: a brew chamber;a coffee chamber having a capacity of at least 200 mL;a filter device positioned along a fluid flow path joining the brew chamber to the coffee chamber;a vacuum source coupled to at least one of the brew chamber and the coffee chamber, the vacuum source being configured to produce a vacuum-based pressure differential between the brew chamber and the coffee chamber of at least 150 torr;a hot water source coupled to the brew chamber; anda controller configured to: direct a first volume of hot water into the brew chamber to contact coffee grounds;activate the vacuum source to force a first volume of coffee, formed from the first volume of water, into the coffee chamber;direct a second volume of hot water into the brew chamber to contact the coffee grounds; andactivate the vacuum source to force a second volume of coffee, formed from the second volume of water, into the coffee chamber to mix with the first volume of coffee. 2. The system of claim 1 wherein the vacuum source is coupled to the coffee chamber. 3. The system of claim 1 wherein the vacuum source is configured to draw a vacuum less than atmospheric pressure in a range of from about 20 torr to about 759.999999999 torr, absolute. 4. The system of claim 1 wherein the instructions, when executed: retain the first volume of hot water in the brew chamber for a period of from 5 seconds to 5 minutes before activating the vacuum source to force the first volume of coffee from the brew chamber. 5. The system of claim 4 wherein the instructions, when executed, activate the vacuum source for a period of from 5 seconds to 60 seconds to direct the first volume of coffee into the coffee chamber. 6. The system of claim 1 wherein the filter device includes a re-useable support element and a disposable filter element. 7. The system of claim 1 wherein the filter device includes a re-useable filter element. 8. The system of claim 1, further comprising an agitation device coupled to the brew chamber to agitate coffee and hot water in the brew chamber. 9. The system of claim 8 wherein the agitation device includes an aerator. 10. The system of claim 1, further comprising a releasable clamp positioned to releasably secure the filter along the fluid flow path. 11. A coffee brewing system, comprising: a brew chamber;a coffee chamber having a capacity of at least 200 mL;a filter device positioned along a fluid flow path joining the brew chamber to the coffee chamber;a vacuum source coupled to the coffee chamber, the vacuum source being configured to produce a pressure differential between the brew chamber and the coffee chamber of at least 60 torr;a hot water source coupled to the brew chamber; anda controller programmed with instructions that, when executed: direct a first volume of hot water into the brew chamber to contact coffee grounds;activate the vacuum source to force a first volume of coffee, formed from the first volume of water, into the coffee chamber;direct a second volume of hot water into the brew chamber to contact the coffee grounds; andactivate the vacuum source to force a second volume of coffee, formed from the second volume of water, as is, into the coffee chamber to mix with the first volume of coffee. 12. The system of claim 11 wherein the instructions, when executed: retain each of the first and second volumes of hot water in the brew chamber for a period of from 5 seconds to 5 minutes before being extracted from the brew chamber;activate the vacuum source for a period of from 5 seconds to 60 seconds to direct the first volume of coffee into the coffee chamber; andactivate the vacuum source for a period of from 5 seconds to 60 seconds to direct the second volume of coffee into the coffee chamber. 13. The system of claim 11 wherein the coffee chamber has a maximum capacity of 12 liters. 14. The system of claim 11 wherein the filter device includes a re-useable support element and a disposable filter element. 15. The system of claim 11 wherein the vacuum source has a capacity of at least one CFM. 16. The system of claim 15 wherein the vacuum source has a capacity of at least one CFM for at least 5 seconds. 17. A coffee brewing system, comprising: a brew chamber;a coffee chamber having a capacity of at least 200 mL;a filter device positioned along a fluid flow path joining the brew chamber to the coffee chamber;a vacuum source coupled to the coffee chamber, the vacuum source being configured to produce a pressure differential between the brew chamber and the coffee chamber of at least 60 torr;a hot water source coupled to the brew chamber; anda controller programmed with instructions that, when executed: direct a first volume of hot water into the brew chamber and onto dry grounds;activate the vacuum source to force a first volume of coffee, formed from the first volume of water, into the coffee chamber;direct a second volume of hot water into the brew chamber and onto an at least partially dried portion of the grounds; andactivate the vacuum source to force a second volume of coffee, formed from the second volume of water, as is, into the coffee chamber to mix with the first volume of coffee.
