Abstract: STARCHIFEROUS MATERIAL SUCH AS POTATOES ARE PULPED; STARCHIFEROUS SOLIDS ARE SEPARATED AND PASSED THROUGH A WASHING SECTION IN WHICH STARCH IS EXTRACTED WITH A LIQUID IN A PLURALITY OF CONTACTING STAGES; THE LIQUID IS PASSED THROUGH THE WASHING SECTION COUNTERCURRENTLY WITH RESPECT TO THE SOLIDS; AND LIQUID FROM THE WASHING SECTION CONTAINING EXTRACTED STARCH IS PASSED TO REFINING SECTION WHEREIN THE STARCH CONTENT THEREOF IS ENHANCED. IN AT LEAST SOME OF THE CONTACTING STAGES, THE LIQUID CONTAINING EXTRACTED STARCH, SEPARATED FROM THE SOLIDS, BEFORE TRANSFER TO THE NEXT PRECEDING CONTACTING STAGE IS CENTRIFUGED TO SEPARATE A CONCENTRATED STARCH MILK, AND THAT MILK IS FED TO THE REFINING SECTION FROM THE WASHING SECTION. IN THIS WAY THE WATER LOAD IN THE REFINING SECTION IS REDUCED.
