Process of brewing tea leaves contained in a capsule
View Patent ↗The invention concerns a process for the preparation of a beverage in a beverage machine with a capsule comprising an enclosure containing tea leaves comprising the steps of: a) introducing water in the capsule to submerge the tea leaves in the capsule enclosure, then b) letting the tea leaves soak, then c) introducing water in the capsule until the required volume of beverage is delivered, wherein water is continuously introduced in the capsule from the beginning of step a) until the end of step b).
1. A process for the preparation of a beverage in a beverage machine using a capsule comprising tea leaves, the process comprising:
a) introducing hot water delivered from a pumping and heating member in the capsule to submerge the tea leaves in the capsule enclosure;
b) letting the tea leaves soak;
c) introducing hot water into the capsule until the required volume of beverage is delivered; and
continuously delivering water from the pumping and heating members during the three steps and continuously introduced in the capsule from the beginning of step a) until the end of step c)
wherein the capsule comprises a filtering wall defining at least one filtering side of the enclosure, and
an overflow wall that is located in the path of the brewed liquid after a filtering wall and comprises at least one overflow aperture,
wherein the filtering wall extends from below a median horizontal plane passing through the enclosure when the capsule is positioned so that the overflow aperture is located above the plane.
2. The process of claim 1 , wherein during step b) the hot water is delivered from the pumping and heating member at a soaking flow of at least 20 ml/min.
3. The process of claim 2 , wherein during step b) the water is delivered from the pumping and heating member at a soaking flow between 20 and 80 ml/min.
4. The process of claim 1 , wherein the quantity of water introduced during step a) is less than the internal volume of the capsule.
5. The process of claim 1 , wherein water is introduced at a temperature of between 30 and 95° C.
6. The process of claim 1 , wherein step b) is performed for a time period that is 5 seconds to 50 seconds.
7. A process for the preparation of a beverage in a beverage machine using a capsule comprising tea leaves, the process comprising:
a) introducing hot water delivered from a pumping and heating member in the capsule to submerge the tea leaves in the capsule enclosure;
b) letting the tea leaves soak;
c) introducing hot water into the capsule until the required volume of beverage is delivered; and
continuously delivering water from the pumping and heating member during the three steps and at least partially sent to waste during step b).
8. The process according to claim 7 , wherein during step b) the hot water is delivered from the pumping and heating member at a soaking flow of at least 20 ml/min.
9. The process according to claim 8 , wherein during step b) the water is delivered from the pumping and heating member at a soaking flow between 20and 80 ml/min.
10. The process of claim 7 , wherein the quantity of water introduced during step a) is less than the internal volume of the capsule.
11. The process of claim 7 , wherein water is introduced at a temperature of between 30 and 95° C.
12. The process of claim 7 using a capsule comprising:
an enclosure containing tea leaves,
a filtering wall defining at least one filtering side of the enclosure, and
an overflow wall that is located in a path of the brewed liquid after a filtering wall and comprises at least one overflow aperture.
13. The process of claim 12 , wherein the filtering wall extends from below a median horizontal plane passing through the enclosure when the capsule is positioned so that the overflow aperture is located above the plane.
14. The process of claim 7 , wherein step b) is performed for a time period that is 5 seconds to 50 seconds.
