US Patent 11001433 Capsule system

A capsule system for expanding the range of application of extraction capsules. The capsule system includes a holding capsule, in which the extraction capsule is held. An annular trough remains between the jacket wall of the extraction capsule and the jacket wall of the holding capsule. The capsule system makes it possible to guide a good in the annular trough with a mixing medium around the extraction capsule and through through-flow openings, while an extraction medium is guided through the extraction capsule. Both media are mixed in a mixing chamber and exit through an outlet opening.
