Description

technical field [0001] The invention relates to a beverage preparation device and its application, in particular to a portable multifunctional coffee extraction device, which can be used for extraction or filtration of various beverages such as coffee and tea. Background technique [0002] Espresso's globally recognized optimal extraction requirements are: a pressure of 8-9 Par, a water temperature of about 93 degrees Celsius, and an extraction time of about 20-25 seconds. However, the existing (non-electric) coffee pots and extraction appliances in the international and domestic markets cannot fully meet the best recognized extraction requirements, nor can they be used for other purposes. . [0003] Moka pots, also known as Napoli pots: In 1903, the Italian Bialetti company began to manufacture and sell them in large quantities. The Moka pot consists of an upper pot, a strainer and a lower pot. The water is placed in the lower pot, and the coffee powder is in the filter ...

AI Technical Summary

Problems solved by technology

Therefore, relying on the form of boiling and extraction in a sealed state, excessive extraction due to excessive water temperature is one of the unchangeable defects of the Moka pot.

[0005] 2) Since it relies on the pressure generated by the water after boiling to extract, the pressure and duration of the extraction process cannot be controlled

[0006] 3) Since the lower pot is heated until the water boils to generate pressure, under the premise of considering the safety factor and product cost, the lower pot is not designed as a boiler, but a simple sealed heating device with a safety valve

[0007] 4) It must be heated by an open flame or an electric heating device to work

Conditions of use and portability are limited

[0008] 5) Since the lower pot is in a sealed and heated state, there are safety issues

[0009] 6) The extraction method and purpose are single

[0011] 1) Due to the use of a lever to pressurize the piston and must cooperate with the base, it is relatively bulky and cannot be used as a portable product

[0012] 2) The extraction method and purpose are single

[0013] 3) Due to the volume material and processing technology, the price is relatively high

Therefore, the extraction pressure is unstable, and the pressure gradually decreases linearly from the beginning to the end of the extraction to 0.

Because it is a portable product, the volume of the gas storage tank is limited, and the pressure drop during the extraction process is an unsolvable problem

[0016] 2) Due to relying on manual pressurized air and the volume of the air storage tank is limited, the entire extraction process cannot reach the ideal extraction pressure of about 8Par, and the extraction time of about 20 seconds

[0017] 3) The manufacturing process is complicated and the purpose is single

[0018] 4) Single source of hot water
