THE PROCESS FOR MAKING DEHYDRATED, SUBSTANTIALLY UNICELLULAR, POTATO GRANULES COMPRISING MIXING ABOUT ONE PART OF ETHANOL WITH TWO PARTS OF COOKED, MASHED POTATOES THUS TO FORM A FLUID SLURRY; DISTILLING A MIXTURE OF ETHANOL AND WATER FROM SAID SLURRY AT A TEMPERATURE OF ABOUT 50 TO 55* C. AND UNDER A REDUCED PRESSURE SUCH THAT THE SLURRY BOILS AT THE OPERATING TEMPERATURE, ETHANOL BEING ADDED DURING THE DISTILLATION TO REPLACE THE FLUID REMOVED BY DISTILLATION, SAID DISTILLATION BEING CONTINUED UNTIL ABOUT 60 PERCENT OF THE WATER IN THE ORIGINAL SLURRY HAS BEEN DISTILLED; THEN ADDING ETHANOL TO THE SLURRY UNTIL THE LIQUID FRACTION OF THE SLURRY CONTAINS AT LEAST ABOUT 80 PERCENT OF ETHANOL; THEN FILTERING THE SLURRY; THEN AGITATING THE FILTER CAKE WHILE PERMITTING THE ETHANOL THEREIN TO EVAPORATE; AND FINALLY DRYING THE POTATOES TO A MOISTURE CONTENT OF NOT MORE THAN ABOUT 7 PER CENT AT A TEMPERATURE OF ABOUT 60 TO 80* C.
