Beverage extraction device

Abstract

Provided is an extraction device for a roasted plant wherein it is possible to keep the preferred flavor component or the rich flavor of an extraction liquid obtained from a roasted plant raw material by means of water extraction while selectively reducing the excessive bitterness of the extraction liquid. Specifically, a granule storing unit is provided with a detachable braking member for housing the granules in a roughly hermetically-sealed manner and housing the granules to be cylindrical or cuboid, the granule storing unit is provided with an upper opening and a lower opening, an upper lid member and a lower lid member are respectively attached detachably to the upper opening and the lower opening, the upper lid member is provided with a valve including a valve body capable of being moved by the action of gravity, and in the generally rectangular sectional shape of the granule layer stored in the granule storing unit in the axial direction, the ratio (H / L) of the width (L) and the height (H) of the rectangle is within a range from 0.1 to 10.

Description

[0001] This application is a divisional application of an invention patent application with an application date of August 24, 2011, an invention title of "beverage extraction device", and an application number of "201180069351.2". technical field [0002] The present invention relates to a beverage extraction device for extracting a beverage extract from roasted plant material through water extraction, for example, relates to a production device for extracting coffee extract by distinguishing coffee flavor components from bitter components. Background technique [0003] Roasted plant materials such as coffee beans, barley for barley tea, tea leaves for roasted tea, etc. are roasted and extracted with hot water, etc. as beverages such as coffee, barley tea, and roasted tea. Roasting process chemically reacts the roasted plant raw materials through heat energy to produce unique aromas such as aroma, rich taste, bitterness, sourness, sweetness and so on. In particular, the burn...

AI Technical Summary

Problems solved by technology

[0011] In the past, although measures to reduce the bitterness, which is an unpleasant component in the extract (leaching solution), were taken, the bitterness was either not sufficiently removed or the rich aroma, flavor, and flavor unique to roasted plants were removed at the same time. Strong taste, so sometimes reduces the flavor of the roasted plant extract itself
