Title: Aromatized coffee extract
IPC: A23F5/48
Filed: 1960-01-19
Abstract: Steam is supplied to the lower extremity of a column, at least five times as high as it is wide, containing roasted coffee, which may be wholly or partly ground, until all the coffee has been wetted to extract the volatile constituents, at the same time separating volatile organic acids from the desired volatile constituents, which are then condensed, and subsequently mixed with water-soluble solids extracted from the steamed coffee. Preferably, the column is cylindrical and between five and twenty times as high as it is wide, and its walls may be cooled.  The volatile constituents may be collected at about 60 DEG F.  The coffee may range from whole beans to 30 mesh particles (United States standard sieve).  When the volatile aromatic flavours have been removed from the column a vacuum of approximately 15 inches of mercury is applied to remove acid vapour which tends to remain. An example is given.
