ABSTRACT:
A process for forming a vegetable extract in a system comprising a series of cells containing coffee and coffee substitute, by contacting progressively fresher vegetable materials countercurrently with an extraction liquid which enters an inlet cell and is withdrawn in batches from an outlet cell characterized in that the outlet cell and each succeeding alternate cell contains more coffee than any one of their respective adjacent cells and during or after each draw-off the pair of cells containing the most exhausted vegetable material is disconnected from the system for discharge and reloading, and after each draw-off a pair of cells with fresh loads of coffee and coffee substitute is added to the system so that the outlet cell is the second in series and contains the majority of coffee of the pair, the amount of soluble solids in each draw-off being approximately twice the amount drawn off in a standard process.
