Lime-carbonation method of refining sugar solutions

Claim 1

THE METHOD OF SUBJECTING RAW SUGAR SOLUTION TO CONTINUOUS PURIFICATION TREATMENT BY THE ADDITION OF LIME IN A QUANTITY SUFFICIENT TO PRECIPITATE IMPURITIES ADAPTED TO BE IN A STATE OF GELATINOUS COAGULATION AND BY REACTION OF CO2 WITH LIME IN THE JUICE FOR RENDERING THE IMPURITY PRECIPITATE SETTLEABLE BY WAY OF THE CACO3 REACTION PRODUCT; CHARACTERIZED BY CONDITIONING THE JUICE PRIOR TO SAID LIME ADDITION IN A MANNER DISCOURAGING THE JUICE IMPURITIES FROM PRECIPITATING IN A COAGULATED GELATINOUS HARDTO-FILTER STATE WHILE ENCOURAGING THE PRECIPITATE TO ASSUME NON-GELATINOUS EASY-TO-FILTER CHARACTERISTICS, WHICH COMPRISES STABILIZING THE RAW SUGAR SOLUTION BY PRELIMINARILY ADDING THERETO A LIMING AGENT HAVING AN ALKALINITY OF SUBSTANTIALLY NOT IN EXCESS OF 0.15% CAO AT A RATE WHEREBY THE JUICE IS BROUGHT TO AN ALKALINITY OF 0.01% CAO TO 0.05% CAO WHEREAFTER THE IMPURITY PRECIPITATE OCCURRING BY THE FOLLOWING LIMING IS RENDERED WITH CACO3 PRECIPITATE AS AN EASY-TO-FILTER SUBSTANTIALLY GRANULAR AGGREGATE.

Claim 2

THE METHOD OF SUBJECTING RAW SUGAR SOLUTION TO CONTINUOUS PURIFICATION TREATMENT BY THE ADDITION OF LIME IN A QUANTITY SUFFICIENT TO PRECIPITATE IMPURITIES ADAPTED TO BE IN A STATE OF GELATINOUS COAGULATION AND BY REACTION OF CO2 WITH LIME IN THE JUICE FOR RENDERING THE IMPURITY PRECIPITATE SETTLEABLE BY WAY OF THE CACO3 REACTION PRODUCT; CHARACTERIZED BY CONDITIONING THE JUICE PRIOR TO SAID LIME ADDITION IN A MANNER DISCOURAGING THE JUICE IMPURITIES FROM PRECIPITATING IN A COAGULATED GELATINOUS HARDTO-FILTER STATE WHILE ENCOURAGING THE PRECIPITATE TO ASSUME NON-GELATINOUS EASY-TO-FILTER CHARACTERISTICS, WHICH COMPRISES STABILIZING THE RAW SUGAR SOLUTION BY PRELIMINARILY ADDING THERETO A LIMING AGENT HAVING AN ALKALINITY OF SUBSTANTIALLY NOT IN EXCESS OF 0.15% CAO AT A RATE WHEREBY THE JUICE IS BROUGHT TO AN ALKALINITY OF 0.01% CAO TO 0.05% CAO WHEREAFTER THE IMPURITY PRECIPITATE OCCURRING BY THE FOLLOWING LIMING IS RENDERED WITH CACO3 PRECIPITATE AS AN EASY-TO-FILTER SUBSTANTIALLY GRANULAR AGGREGATE.
