Abstract
Device for preparing a coffee drink having a visually appealing crema layer comprises a container for receiving flavor-containing materials and allowing it to interact with pressurized hot water to produce a coffee drink, an orifice for converting the coffee drink into a high speed drink jet, and a cyclone channel located below the orifice and adapted to interact with the jet to generate a cyclone zone therein during preparing the coffee drink. The cyclone zone stays alive by constantly drawing air in from atmosphere to emulsify with the coffee drink within the cyclone zone and constantly driving the resulting emulsion out of the cyclone zone as a result of the momentum of the jet. The emulsion separates into a coffee drink layer and a crema layer on top of the coffee drink upon being received in a cup.
