Pressurizing-type portable coffee extraction equipment

Abstract

The invention relates to the field of coffee extraction equipment, in particular to pressurizing-type portable coffee extraction equipment. The pressurizing-type portable coffee extraction equipment is characterized in that a manual pressurizing cover, a cup body, a pressurizing piston assembly and an integrated filter screen assembly are included; the cup body is of a cylindrical structure of which the upper end and the lower end are open, a partition plate is arranged in the cup body and partitions an internal space of the cup body into a piston chamber and a high-pressure coffee extraction chamber, and a circular sealing groove hole is formed in the center of the partition plate; the pressurizing piston assembly comprises a piston, and the piston is located in the piston chamber; the manual pressurizing cover is provided with an outer thread and is in threaded connection with the upper end of the cup body; the integrated filter screen assembly comprises a filter screen cover, a filter screen and a filter outlet cover, the filter screen is arranged in the filter screen cover, and a circular out-in opening is formed in the filter screen cover. According to the equipment, a pressurized extraction technology and a portable function are combined, and professional concentrated coffee can be made at any place extremely fast and conveniently.

Description

technical field [0001] The invention relates to the field of coffee extraction equipment, in particular to a pressurized portable coffee extraction equipment. Background technique [0002] Espresso (Espresso) or Italian espresso is a type of coffee with a strong taste. The method is to use hot water at 90-95 degrees Celsius and use high pressure of about 9-10bar to rush through finely ground coffee powder. Coffee, the time is controlled within 25-35 seconds, usually consumed directly or as the basis for making coffee drinks, such as latte, cappuccino, macchiato, and mocha. [0003] The preparation of espresso requires high equipment. The currently available coffee machines for making espresso are as follows: [0004] Commercial vane pump heating water boiler coffee machine: use vane pump to pump normal temperature water, enter the high temperature boiler that has been preheated and contain a large amount of hot water, usually ranging from a few liters to more than ten liter...
