Adsorbent particle sizing for gas dissolution in beverages

摘要

Systems, methods and cartridges for carbonating or otherwise dissolving gas in a precursor liquid, such as water, to form a beverage. A gas source can be provided in a cartridge which is used to generate gas that is dissolved into the precursor liquid. A beverage medium, such as a powdered drink mix or liquid syrup, may be provided in the same, or a separate cartridge as the gas source and mixed with the precursor liquid to form a beverage. The gas source may include a solid molecular sieve formed in beads in which at least 85% of the beads by weight have a size of 0.71 mm to 2.0 mm.

主权项

1. A cartridge for use by a beverage forming machine in forming a beverage, comprising:
a container including a first chamber that is sealed and encloses a gas source material arranged to release a gas adsorbed by the gas source material with addition of a fluid introduced into the first chamber, the gas source material being a zeolite formed in solid beads in which at least 85% of the beads by weight have a size of 0.71 mm to 2.0 mm and less than 5% of the beads have a size over 2.0 mm, wherein the container is arranged to have an inlet through which the fluid is introduced by the beverage forming machine into the first chamber to cause the gas source material to release the gas, and is arranged to have an outlet through which gas released by the gas source material exits the first chamber for dissolution in the beverage.
