Claim 1
Independent Claim
183 words
THE METHOD OF PREPARING SUGAR-COATED DICALCIUM PHOSPHATE PARTICLES SUITABLE FOR INCORPORATION INTO CHEWING GUM, COMPRISING THE STEPS OF ADMIXING A PREDETERMINED WEIGHT OF DICALCIUM PHOSPHATE IN FINE PARTICLE FORM WITH ABOUT AN EQUAL WEIGHT OF SUGAR IN THE FORM OF AN AQUEOUS SOLUTION, IN WHICH SAID AQUEOUS SOLUTION CONTAINS AND AMOUNT OF WATER, ABOUT 15%, SUCH THAT THE HEAT CONTENT OF SAID SOLUTION AND SAID PREDETERMINED WEIGHT OF DICALCIUM PHOSPHATE AT THE TIME OF THE ADMIXING AFORESAID, PLUS THE LATENT HEAT OF CRYSTALLIZATION OF THE SUGAR CONTAINED IN SAID SOLUTION WILL BE SUFFICIENT TO EVAPORATE THE WATER PRESENT, SO AS TO PRODUCE A SUBSTANTIALLY DRY PRODUCT, THE ADMIXTURE PREPARED AS AFORESAID BEING INITIALLY IN THE FORM OF A SLURRY AND SUBSTANTIALLY CONTINUOUSLY AGITATING THE SLURRY THUS FORMED DURING THE CONVERSION OF THE SUGAR IN SAID AQUEOUS SOLUTION FROM ITS LIQUID STATE TO A CRYSTALLINE STATE, SO AS TO PRODUCE A SUBSTANTIALLY DRY MATERIAL CONSISTING OF THE CRYSTALLINE SUGAR-COATED DICALCIUM PHOSPHATE PARTICLES IN A FLOWABLE DISCRETE PARTICULATE FORM WITHOUT SUPPLYING HEAT FROM ANY EXTERNAL SOURCE TO SAID SLURRY DURING THE EVAPORATION OF WATER THEREFROM.
