Ion exchange treatment of sugar solutions

Claim 1

THE METHOD OF PURIFYING A SUGAR-BEARING SOLUTION TO REMOVE THEREFROM NON-SUGAR SOLUTES SUCH AS INORGANIC SALTS BY PASSING THE SOLUTION SEQUENTIALLY THROUGH AN ACID REGENERATED BED OF CATION EXCHANGE MATERIAL AND AN ALKALI REGENERATED BED OF ANION EXCHANGE MATERIAL, CHARACTERIZED BY PASSING SUGAR SOLUTION HAVING BEEN RENDERED ACID BY CATION EXCHANGE THROUGH A BED OF ANION EXCHANGE MATERIAL TO A POINT OF INCOMPLETE EXHAUSTION THEREOF, WASHING RESIDUAL SUGAR SOLUTION FROM THE BED TO LEAVE THE INFLUENT ZONE REPRESENTING A MAJOR PORTION OF THE BED EXHAUSTED WITH H+-IONS AND THE COMPLEMENTARY ZONE OF THE BED INCLUDING THE EFFLUENT END THEREOF CONTAINING A SIGNIFICANT QUANTITY OF ALKALIZING OH--IONS FORMED DUE TO CONTACT OF TRACES OF RESIDUAL NONSUGAR SOLUTES IN THE JUICE WITH ALKALI-REGENERATED ANION EXCHANGE MATERIAL, PASSING AUXILIARY ACID SOLUTION THROUGH THE BED IN THE DIRECTION IN WHICH THE ACID SUGAR SOLUTION HAS PASSED THERETHROUGH UNTIL SAID OH--IONS IN THE COMPLEMENTARY ZONE WILL HAVE BECOME REPLACED WITH H+-IONS, WASHING THE BED FREE OF SAID AUXILIARY SOLUTION TO LEAVE THE BED SUBSTANTIALLY ENTIRELY EXHAUSTED WITH H+-IONS, PASSING THROUGH THE BED ALKALI REGENERANT SOLUTION IN THE DIRECTION IN WHICH SAID ACID SUGAR SOLUTION AND SAID AUXILIARY ACID SOLUTION HAVE PASSED THERETHROUGH UNTIL ALL OF THE BED EXCEPT SAID COMPLEMENTARY ZONE WILL HAVE BECOME ALKALI REGENERATED, WASHING SAID INFLUENT ZONE FREE OF RESIDUAL REGENERANT SOLUTION TO LEAVE THE BED ALKALI-REGENERATED WHILE LEAVING SAID COMPLEMENTARY ZONE BUFFERED WITH H+-IONS, AND AGAIN PASSING THROUGH THE BED SUGAR SOLUTION RENDERED ACID BY CATION EXCHANGE TO ALLOW ALKALIZING OH-IONS FORMED IN THE SUGAR SOLUTION DUE TO CONTACT OF TRACES OF RESIDUAL DISSOLVED NON-SUGAR IN THE JUICE WITH ALKALI-REGENERATED ANION EXCHANGE MATERIAL TO DISPLACE BUFFERING H+-IONS FROM SAID COMPLEMENTARY ZONE INTO THE SUGAR SOLUTION PASSING THEREFROM, WHEREBY THE BED IS LEFT WITH SAID INFLUENT ZONE EXHAUSTED BY H+-IONS AND SAID COMPLEMENTARY ZONE IS LEFT REGENERATED WITH OH-IONS, THE PROPORTIONING OF THE DEPTHS OF THE RESPECTIVE ZONES RELATIVE TO EACH OTHER BEING SO CHOSEN THAT THERE RESULTS A PURIFIED SUGAR SOLUTION PASSING FROM THE BED AT A PH OF A DESIRED AND SUBSTANTIALLY UNIFORM VALUE.

Claim 2

THE METHOD OF PURIFYING A SUGAR-BEARING SOLUTION TO REMOVE THEREFROM NON-SUGAR SOLUTES SUCH AS INORGANIC SALTS BY PASSING THE SOLUTION SEQUENTIALLY THROUGH AN ACID REGENERATED BED OF CATION EXCHANGE MATERIAL AND AN ALKALI REGENERATED BED OF ANION EXCHANGE MATERIAL, CHARACTERIZED BY PASSING SUGAR SOLUTION HAVING BEEN RENDERED ACID BY CATION EXCHANGE THROUGH A BED OF ANION EXCHANGE MATERIAL TO A POINT OF INCOMPLETE EXHAUSTION THEREOF, WASHING RESIDUAL SUGAR SOLUTION FROM THE BED TO LEAVE THE INFLUENT ZONE REPRESENTING A MAJOR PORTION OF THE BED EXHAUSTED WITH H+-IONS AND THE COMPLEMENTARY ZONE OF THE BED INCLUDING THE EFFLUENT END THEREOF CONTAINING A SIGNIFICANT QUANTITY OF ALKALIZING OH--IONS FORMED DUE TO CONTACT OF TRACES OF RESIDUAL NONSUGAR SOLUTES IN THE JUICE WITH ALKALI-REGENERATED ANION EXCHANGE MATERIAL, PASSING AUXILIARY ACID SOLUTION THROUGH THE BED IN THE DIRECTION IN WHICH THE ACID SUGAR SOLUTION HAS PASSED THERETHROUGH UNTIL SAID OH--IONS IN THE COMPLEMENTARY ZONE WILL HAVE BECOME REPLACED WITH H+-IONS, WASHING THE BED FREE OF SAID AUXILIARY SOLUTION TO LEAVE THE BED SUBSTANTIALLY ENTIRELY EXHAUSTED WITH H+-IONS, PASSING THROUGH THE BED ALKALI REGENERANT SOLUTION IN THE DIRECTION IN WHICH SAID ACID SUGAR SOLUTION AND SAID AUXILIARY ACID SOLUTION HAVE PASSED THERETHROUGH UNTIL ALL OF THE BED EXCEPT SAID COMPLEMENTARY ZONE WILL HAVE BECOME ALKALI REGENERATED, WASHING SAID INFLUENT ZONE FREE OF RESIDUAL REGENERANT SOLUTION TO LEAVE THE BED ALKALI-REGENERATED WHILE LEAVING SAID COMPLEMENTARY ZONE BUFFERED WITH H+-IONS, AND AGAIN PASSING THROUGH THE BED SUGAR SOLUTION RENDERED ACID BY CATION EXCHANGE TO ALLOW ALKALIZING OH-IONS FORMED IN THE SUGAR SOLUTION DUE TO CONTACT OF TRACES OF RESIDUAL DISSOLVED NON-SUGAR IN THE JUICE WITH ALKALI-REGENERATED ANION EXCHANGE MATERIAL TO DISPLACE BUFFERING H+-IONS FROM SAID COMPLEMENTARY ZONE INTO THE SUGAR SOLUTION PASSING THEREFROM, WHEREBY THE BED IS LEFT WITH SAID INFLUENT ZONE EXHAUSTED BY H+-IONS AND SAID COMPLEMENTARY ZONE IS LEFT REGENERATED WITH OH-IONS, THE PROPORTIONING OF THE DEPTHS OF THE RESPECTIVE ZONES RELATIVE TO EACH OTHER BEING SO CHOSEN THAT THERE RESULTS A PURIFIED SUGAR SOLUTION PASSING FROM THE BED AT A PH OF A DESIRED AND SUBSTANTIALLY UNIFORM VALUE.
