THE METHOD OF CONTINUOUSLY RECOVERING ESTERS AND OTHER VOLATILE COMPONENTS OF FLAVORS AND AROMAS FROM A FLUID WHICH CONSISTS IN CONTINUOUSLY MIXING WITH THE FLUID A NORMALLY NONCONDENSABLE GAS, CONTINUOUSLY SEPARATING SAID GAS WITH THE VOLATILE FLAVOR AND AROMA COMPONENTS FROM THE MIXTURE WHILE THE LATTER IS MAINTAINED AT A SUB-ATMOSPHERIC PRESSURE, CONTINUOUSLY REMOVING SAID FLUID FROM THE MIXTURE, CONTINUOUSLY CONDUCTING SAID GAS WITH THE STRIPPED VOLATILES AND CONDENSABLE VAPOR IN CO-CURRENT RELATIONSHIP AWAY FROM SAID MIXTURE AND REMOVING THE CONDENSABLE VAPOR THEREFROM, THENCE CONDUCTING THE STRIPPED VOLATILES AND GAS IN COCURRENT RELATIONSHIP TO A POINT WHERE THE VOLATILES ARE SEPARATED FROM THE NON-CONDENSABLE GAS IN THE FORM OF SOLID CRYSTALS, AND CONVERTING SAID CRYSTALS INTO A FLUID.
