Abstract

The invention relates to a device for extracting fusel oil by alcohol distillation. The device comprises an alcohol refining tower, a fusel oil separator, a raw material inlet, a finished product outlet, a fusel oil collecting point and a low boiling point impurity collecting point, wherein the raw material inlet is formed in the middle-lower part of the alcohol refining tower; the finished product outlet is formed in the middle-upper part of the alcohol refining tower; the low boiling point impurity collecting point is arranged on the top of the alcohol refining tower; the fusel oil collecting point is formed above the raw material inlet; the fusel oil separator is connected with the fusel oil discharge point; the fusel oil separator is sequentially connected with a cooler, an observation cover, an emulsifier and a separator through a pipeline in sequence; the bottoms of the fusel oil separator and the alcohol refining tower are communicated. The device is capable of thoroughly separating and collecting unstable alcohol and distilling and extracting the fusel oil.

Description

[0001] technical field [0002] The invention relates to the field of alcohol rectification, in particular to a device for extracting fusel oil by alcohol rectification. Background technique [0003] Fusel oil, like ethanol, is a normal metabolite of alcoholic fermentation by yeast. Fusel oil is an intermediate impurity, in the shape of a jujube nucleus, with very long tails at both ends, and tends to accumulate dynamically in the middle of the alcohol refining tower. Fusel oil is not easy to separate when the alcohol concentration is high. The traditional process is to separate the liquid phase of fusel oil at the raw material inlet. The separation of fusel oil produced by this process is not complete and the recovery is unstable. Contents of the invention [0004] The object of the present invention is to provide a device for extracting fusel oil through rectification and extraction of unstable alcohol with complete separation. [0005] For achieving above object, t...
