Process for production of alginates |
| abstract |
AN IMPROVED EXTRACTION PROCEDURE FOR REMOVING ALGINIC ACID FROM KELP. THE KELP IN A COMMINUTED FORM IN ADMIXTURE WITH WATER IS PASSED THROUGH AN EXTRACTOR UNDER CONDITIONS WHICH APPROXIMATE PLUG FLOW. THE COMMINUTED KELP IS INTRODUCED TO THE EXTRACTOR IN ADMIXTURE WITH SODIUM CARBONATE AND WATER WHERE IT IS THEN IMMEDIATELY HEATED TO A TEMPERATURE OF ABOUT 190 TO ABOUT 270*F. BY PRESSURIZED STEAM. THE RESIDENCE TIME OF THE MATERIALS WITHIN THE EXTRACTOR RANGES FROM ABOUT 10 TO ABOUT 40 MINUTES. BY PROVIDING CONDITIONS WHICH PRODUCE ESSENTIALLY PLUG FLOW WITHIN THE EXTRACTOR, ALL OF THE MATERIAL PASSING THROUGH THE EXTRACTOR IS SUBJECTED TO SUBSTANTIALLY THE SAME CONDITIONS TO PRODUCE ON A CONTINUOUS BASIS A PRODUCT HAVING GENERALLY UNIFORM CHARACTERISTICS. |
