1results about How to "High contact density" patented technology

The utility model discloses a high pressure type coffee extraction device, and it improves the coffee quality through two-stage dynamic extraction mechanism: the first stage utilizes the steam generated by steam generating device to flow into the upper shell of extraction device through pipeline, and the steam flows to steam buffer area through the first steam perforation of upper shell, and the steam flows to coffee powder through the second steam perforation of tabletting, and the coffee powder is wetted, and after the upper part or all of coffee powder in coffee powder containing area is wetted, the second stage is entered: the tabletting falls and compacts coffee powder through pressure under the pressure trigger of extraction device, and the contact density of steam and coffee powder is greatly increased, and the penetration efficiency bottleneck of traditional pure steam extraction is broken. The design realizes the synergistic effect of "wetting first and compacting later" without external mechanical intervention, not only improves the extraction uniformity and soluble matter extraction rate, but also endows the coffee liquid with more abundant oil and mellow taste, and the structure is simple and reliable, and the operation degree of automation is high.
