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.

A beverage dispensing apparatus being formed so as in use to provide a vortex motion in the mass of beverage flowing through the apparatus. In the vortexial flow, a low pressure area is produced at the center of the vortex so that the pressure in that region falls below equilibrium pressure and thus results in gas separating out from the liquid beverage. Since the gas breakout is achieved without the need for a flow restrictor, the pressure drop associated with these devices does not occur. Consequently, the beverage may enter the apparatus at a lower pr...

1. Beer dispensing apparatus, the apparatus comprising a flow chamber having a substantially circular cross section, an inlet and an outlet, wherein the apparatus is configured such that in use a vortexial motion is formed in the mass of beer flowing through the apparatus such that gas separates out from the beer within the vortex formed an a head is formed on beer dispensed from the apparatus. 2. A beer dispensing apparatus as claimed in claim 1, wherein the inlet extends substantially at a tangent to the circular cross section of the flow chamber. 3. A beer dispensing apparatus as claimed in claim 2, wherein the inlet is a conduit which extends substantially perpendicular to the longitudinal axis of the flow chamber. 4. A beer beverage dispensing apparatus as claimed in claim 1, a vortex finder being provided within the flow chamber aligned in relation to the inlet such that in use, beer flowing into the flow chamber is guided in a circular path between the surface of the vortex finder and the inner face of the flow chamber. 5. A beer dispensing apparatus as claimed in claim 4, wherein the vortex finder comprises a portion in the form of a cylinder. 6. A beer dispensing apparatus as claimed in claim 5, wherein the vortex finder further comprises a conic or frusto-conic part provided at the downstream end thereof. 7. A beer dispensing apparatus as claimed in claim 5, wherein the vortex finder is provided integrally with a valve head. 8. A beer dispensing apparatus as claimed in claim 1, the apparatus being arranged to be oriented substantially vertically in use such that the beer flows helically downwardly through the apparatus under the action of gravity. 9. A beer dispensing apparatus as claimed in claim 1, wherein the circular cross section of at least a part of the flow chamber decreases in diameter along its axis in the downstream flow direction. 10. A beer dispensing apparatus as claimed in claim 1, wherein a vortex breaker is provided in the apparatus to smooth the flow of beer leaving the apparatus. 11. A beer dispensing apparatus as claimed in claim 1, the flow chamber comprising a hollow cylindrical upstream portion defining a vortex finding chamber and a conical or frusto-conical downstream portion depending therefrom. 12. A beer dispensing apparatus as claimed in claim 1, further comprising means for opening and closing the flow of beer into the apparatus. 13. A beer dispensing apparatus as claimed in claim 7, further comprising an outlet conduit leading from the flow chamber, wherein the inlet is arranged in relation to the flow chamber such that beer flowing into the apparatus in use is directed to flow around the valve head substantially in one direction. 14. A beer dispensing apparatus as claimed in claim 13, wherein the outlet conduit depends from the flow chamber and is arranged such that the flow of beer around the valve head establishes a vortex flow within the outlet conduit. 15. beer dispensing apparatus as claimed in claim 13, wherein a vortex breaker is provided in the outlet conduit to smooth the flow of beer leaving the apparatus. 16. A beer dispensing apparatus as claimed in claim 13, wherein the valve head is axially movable within the flow chamber in such a way that the valve head opens and closes the inlet conduit. 17. A beer dispensing apparatus as claimed in claim 16, wherein the valve head is provided with a vortex finding portion having a diameter significantly less than that of the flow chamber and a valve portion having a diameter substantially the same as that of the flow chamber, and the valve portion is operable to open and close the inlet conduit. 18. A beer dispensing apparatus as claimed in claim 1, the apparatus being made of stainless steel. 19. A beer dispensing apparatus as claimed in claim 1, the apparatus being made of glass. 20. A beer dispensing apparatus as claimed in claim 1, the apparatus being made of plastics. 21. A beer dispensing apparatus as claimed in claim 20, the a pparatus being made of Perspex. 22.
