System for producing a tea beverage

Abstract

The invention relates to a single serve capsule for producing tea, comprising a capsule body with a capsule base and a filling side. A cavity for accommodating a powdered or liquid tea granulate is formed between the capsule base and the filling side, a filter element is arranged between the tea granulate and the capsule base, and said filter element comprises a filter structure which is arranged in the region of the capsule base.

1 . A system for producing a tea beverage, comprising a brewing chamber and a portion capsule having a cavity in which fruit tea granules are contained, wherein the portion capsule is provided in the brewing chamber and a liquid flows through the brewing chamber and the portion capsule and, in the process, extracts and/or desorbs the fruit tea granules and as a result produces a fruit tea beverage, wherein the fruit tea granules are provided such that the square of the average volumetric flow rate, measured in millimeters, divided by the time in seconds required for producing the beverage, is at least 1.3. 
     
     
         2 . The system according to  claim 1 , wherein the Dv50 of the fruit tea granules is about 300-about 1000 μm. 
     
     
         3 . The system according to  claim 1 , wherein the swelling index of the fruit tea granules is about 1.8-about 4.0. 
     
     
         4 . The system according to  claim 1 , wherein a weighed portion of the fruit tea granules is about 0.4-about 7.0 g. 
     
     
         5 . The system according to  claim 1 , wherein a volume of the cavity is about 20-about 30 ml. 
     
     
         6 . The system according to  claim 1 , wherein a filter element is provided in the cavity. 
     
     
         7 . The system according to  claim 6 , wherein the filter element has a felt structure, and the felt structure has a mass per unit area of between about 600 and about 1500 grams per square meter. 
     
     
         8 . The system according to  claim 6 , wherein a thickness of the filler element is between about 0.8 and about 3.3 millimeters. 
     
     
         9 . The system according to  claim 1 , wherein a capsule base has an output opening which is sealed off using a film or foil. 
     
     
         10 . The system according to  claim 1 , wherein fruit tea granules contain fine cuts of apple, in ground and/or unground form, and/or lemongrass, and/or ginger. 
     
     
         11 . The system according to  claim 2 , wherein the Dv50 of the fruit tea granules is about 350-about 900 μm. 
     
     
         12 . The system according to  claim 3 , wherein the swelling index of the fruit tea granules is about 2.0-about 3.8. 
     
     
         13 . The system according to  claim 4 , wherein the weighed portion of the fruit tea granules is about 0.5-about 5.0 g. 
     
     
         14 . The system according to  claim 7 , wherein the mass per unit area of the felt structure is between about 1000 and about 1400 grams per square meter. 
     
     
         15 . The system according to  claim 14 , wherein the mass per unit area of the felt structure is between about 1200 and about 1300 grams per square meter. 
     
     
         16 . The system according to  claim 8 , wherein the thickness of the filter element is between about 1.1 and about 3.0 millimeters. 
     
     
         17 . The system according to  claim 18 , wherein the thickness of the filter element is between about 1.2 and about 1.4 millimeters. 
     
     
         18 . The system according to  claim 9 , wherein the film or foil has a pull-off tab for pulling off the film or foil by hand.
