143 words
THE METHOD OF HEAT TREATING LACTEAL FLUIDS IN A CONTINOUS ONCE-THROUGH VACUUM PASTEURIZATION PROCESS, WHICH INCLUDES PREHEATING THE FLUID FOR A SHORT TIME INTERVAL UNDER ATMOSPHERIC CONDITIONS TO A TEMPERATURE WITHIN THE RANGE OF APPROXIMATELY 110*F. TO 160*F., SUBJECTING THE PREHEATED FLUID IN FINELY DIVIDED FORM TO THE ACTION OF STEAM AND RAISING THE TEMPERATURE OF THE FLUID TO APPRIXIMATELY 162*F. TO 185*F. WHILE PASSING THROUGH A FIRST VACUUM ZONE RANGING FROM APPROXIMATELY 20 TO 12 INCHES OF MERCURY, THEN PASSING THE FLUID THROUGH A SECOND VACUUM ZONE RANGING FROM APPROXIMATELY 21 TO 13 INCHES OF MERCURY FOR WITHDRAWING VAPORS AND GASES FROM THE FLUID, THEN HOLDING THE FLUID AT A SUITABLE TEMPERATURE AT APPROXIMATELY 160*F. TO 183*F. FOR NOT LESS THAN 15 SECONDS TO COMPLETE PASTEURIZATION OF, WHILE SUBSTANTIALLY CONTROLLING THE LIPOLYTIC ACTIVITY WITHIN, THE FLUID, AND THEN VACUUM COOLING THE FLUID.
