ABSTRACT:
The invention relates to a method and a device for ensuring the sterility of distillate in a multi-stage distilling machine. All feed water of the multi-stage distilling machine flows through a first column operating at the highest temperature so that the temperature of the feed water is equal to or greater than about 121.degree. C., about 131.degree. C., and about 141.degree. C., respectively, and the delay time after the feed water is removed from the first column and before its entry into the first column is at least about 8 minutes, about 0.8 minutes, 0.08 minutes, respectively. The delay produces the result that the distillate of every column of the multi-stage distilling machine is sterile, including that of the last column operating at the lowest temperature. The feed water flows through a first flow line from a second column to the first column, from the first column through a second flow line to a heat exchanger and returns from the heat exchanger through a third flow line to the first column.
