High-power foaming method and device of coffee

Abstract

The invention discloses a high-power foaming method and device of coffee. The high-power foaming device comprises a pressure control mechanism, an air pressure source, a water storage device and a back pressure resonance mechanism, wherein a coffee outlet is formed in the lower part of the back pressure resonance mechanism. When a button is pressed, 6 to 8bar pressure water in a portable coffee making machine or 9 to 11bar pressure water in a desk type coffee making machine enters a coffee placement cavity and is dissolved with the coffee to extract. A resonance needle and a rubber ring form aresonance cavity; when coffee paste with pressure passes through the resonance cavity, the coffee paste is sufficiently processed into foam after high-frequency vibration due to the pressure coffee paste and a special structure of the resonance cavity, and then the foam flows out from the coffee outlet. The high-power foaming device disclosed by the invention has the advantages that the structureoccupied a very small space and can be applied to large and small e coffee making machines with any type; the coffee foam of the coffee produced by the method and the structure can reach 70 percent.

Description

technical field [0001] The invention relates to coffee machine manufacturing technology, in particular to a method and device for high-expansion foaming of coffee. Background technique [0002] In the prior art, in order to make the brewed coffee produce enough foam, people have made many innovations and produced many patented technologies, such as: [0003] Patent No. ZL200620008268.0 is a Chinese utility model patent named coffee foaming device. Its water outlet valve core belongs to the traditional structure of applying pressure to spray coffee. Although it has foaming effect, the foaming efficiency is not high. [0004] Have again, patent No. 200920193566.5, the name is the Chinese utility model patent of the coffee frothing device of coffee machine, its principle is that the coffee slurry is sprayed onto the filter screen by the water outlet, fully fused with air and frothed, though there is a foaming effect, but The foaming efficiency is still not high. [0005] Have...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to solve the problem that most of the foaming of coffee in the prior art adopts the principle of high-pressure steam jet sputtering, and the foaming effect is not good. Design a specific resonant element and structure, so that the coffee slurry is oscillating and atomized under its action, and the foaming rate is doubled
