WIPO Patent Application WO/2022/191479
Kind Code:
A1
Abstract:
The present invention relates to espresso extraction device and method. The espresso extraction method is performed by a valve unit which adjusts, on the basis of sensing data of a sensor unit provided in an extraction unit of an espresso extraction device, the pressure applied to the extraction unit, or a control unit which controls the operation of a pressure unit. The espresso extraction method comprises the steps of: mounting a portafilter to a head of the extraction unit; filling the pressure unit with a fluid and controlling the operation of the valve unit to remove bubbles in the pressure unit; filling the extraction unit with a fluid and controlling the operation of the valve unit to remove bubbles in the extraction unit; operating the pressure unit and applying pressure to the fluid filled in the extraction unit to extract espresso; receiving an extraction pressure in the extraction unit via the sensor unit; and controlling the operation of the pressure unit on the basis of the extraction pressure.
