Method of producing starch from starch milk

Claim 1

IN THE TREATMENT OF MAIZE STARCH MILK CONTAINING FIBERS AND GLUTEN, IN WHICH THE STARCH MILK IS SUBJECTED TO A FIRST SEPARATING OPERATION TO SEPARATE IT INTO TWO COMPONENTS, ONE OF WHICH, THE UNDERFLOW, CONTAINS MOST OF THE STARCH, AND THE SECOND OF WHICH, THE OVERFLOW, CONTAINS FIBERS AND GLUTEN AND SOME STARCH, AND IN WHICH THE STARCH UNDERFLOW IS DILUTED AND SUBJECTED TO A SECOND SEPARATING OPERATION TO SEPARATE OUT AN OVERFLOW CONTAINING SOME STARCH AND MOST OF THE FIBERS AND GLUTEN, THE IMPROVEMENT WHICH COMPRISES CONCENTRATING THE OVERFLOW FROM THE FIRST SEPARATION IN A LOCUS OF CENTRIFUGAL SEPARATION TO OBTAIN A CONCENTRATE ENRICHED IN STARCH, AT LEAST SOME OF WHICH IS ENTRAINED IN GLUTEN, COMBINING SAID LAST CONCENTRATE WITH THE OVERFLOW FROM SAID SECOND SEPARATION, AND FEEDING THE RESULTING MIXTURE TO A CENTRIFUGAL PURIFIER AND THERE SUBJECTING IT TO AN ADDITIONAL CENTRIFUGAL SEPARATION WHICH IS RELATIVELY PROLONGED AS COMPARED WITH SAID CENTRIFUGAL CONCENTRATING OPERATION AND WHICH PROVIDES A GREATER SELECTIVE SEPARATING ABILITY THAN SAID OPERATIONS, TO RECOVER THE STARCH FROM THE MIXTURE.
