发明名称 PROCESS FOR EXTRACTING COFFEE
摘要 A process for preparing an extract from ground, roasted coffee is described. A primary extract is prepared by exhaustive primary extraction with water or an aqueous solution in one or more extraction cells including one cell to which extraction liquid is supplied. A secondary extract is prepared by secondary extraction with water or an aqueous solution in one or more extraction cells including one cell from which secondary extract is drawn off. The process is conducted so that when the primary extraction cell to which the water or the aqueous solution is supplied has been exhaustively extracted, this cell is connected through to the secondary extraction as an extraction cell from which secondary extract is withdrawn, and the first quantity of extract from the cell connected through, which quantity corresponds approximately to the liquid contents of said cell, is supplied to the primary extraction as an extraction liquid.
