Abstract
A device for continuously decaffeinating raw coffee includes a first extractor having at least one cell for use in a first treatment stage where raw coffee is preswollen by a swelling fluid that is added to the raw coffee. The at least one cell receives the raw coffee that is to be preswollen and is defined by a bottom and a plurality of sidewalls that extend towards one another to define a wedge-shaped cell. Additional similarly shaped cells and receiving chambers positioned below the cells may also be provided with a perforated bottom separating each cell from its respective receiving chamber.
