Abstract
An apparatus for high yield foaming of coffee has a pressure control mechanism, a gas pressure source, a water reservoir and a back pressure resonance mechanism, wherein a coffee outlet is arranged at a lower part of the back pressure resonance mechanism. When a button is pressed, water having a controlled water pressure enters a coffee placement cavity to be mixed with the coffee and extracted. One resonance needle and a colloid ring constitute a resonance cavity. When pressed coffee slurry passes through the resonance cavity, due to the pressed coffee slurry and a special structure of the resonance cavity, the coffee slurry is sufficiently foamed after high-frequency oscillation and flows out of the coffee outlet.
