Question

A countercurrent extraction system is to treat 100 kg/min of sliced sugar beets with fresh water as solvent. Analysis of the beets is as follows:

                                water                      48%

                                sugar                      12%

                                pulp                        40%

 

97% sugar is to be recovered and the extract phase leaving the system is to contain 15% sugar. Determine the number of cells required if each kg of dry pulp retains 3 kg of water.
