More Information
Summary:The process, which is for preparing "freeze distilled" alcohol for use in beverages such as vodka, comprises the partial or complete removal of fusel oil (i.e. >C2 alcohols) from an aqueous, alcoholic fraction taken from a distillation column at 80-95{C by (a) cooling the fraction to below c. 0{C to reduce the solubility of the fusel oil therein, and preferably rendering it substantially insoluble; (b) separating the aqueous fraction from the fusel oil; and (c) returning the aqueous fraction to the distillation. Apparatus for carrying out the process comprises a distillation column 1, a pump 2, heat exchangers 3 and 4 (in the latter of which the fraction is cooled to -10{C by ammonia 8), a separation tank 5 and a pump 7.
