AI Technical Summary

Technical Problem

Existing coffee brewing equipment suffers from problems such as uneven coffee puck extrusion, poor extraction, inconvenience in removing coffee pucks, and difficulty in disassembling brewing tanks.

Method used

A coffee brewing device has been designed, including a detachable brewing barrel assembly, a detachable upper pressure rod assembly, and a lower push rod assembly. The device forms a uniformly dense coffee cake through joint extrusion in both the upper and lower directions. The lower push rod assembly pushes the coffee cake to the top of the brewing barrel. Combined with a central rotating assembly, it achieves automated coffee dropping and extrusion station switching. It is equipped with a waste scraper for automatic cleaning, ensuring convenient operation and high efficiency.

Benefits of technology

It improves coffee extraction efficiency and taste, simplifies the process of removing coffee pucks and changing brewing barrels, and achieves fully automated operation, thus improving ease of operation and brewing efficiency.

Abstract

The invention relates to the field of coffee brewing, in particular to a coffee brewing device and method. The device comprises a mounting frame, and a brewing barrel assembly is detachably arranged on the lower portion of the mounting frame and comprises a brewing barrel, a lower push rod assembly and a top water inlet assembly. And a water outlet assembly is arranged at the bottom of the upper pressing rod assembly, is positioned above the opening of the brewing barrel, and can fall powder and push the water outlet assembly to vertically move. The water inlet assembly and the water outlet assembly extrude powder into pressed powder in the barrel, the water inlet assembly adds water for extraction, and the water outlet assembly discharges coffee; after extraction, the lower push rod assembly pushes the water inlet assembly to lift the pressed powder to the top of the barrel. The problems that an existing device is uneven in pressed powder extrusion, poor in extraction effect, inconvenient to take out pressed powder, difficult in brewing barrel disassembly and poor in adaptability are solved.
