Description

Distilled liquor preheating device

Technical Field

The utility model relates to the technical field of wine industry manufacturing, in particular to a distilled liquor pre-heating device.

Background

Distilled liquor is a variety of alcoholic beverages with higher ethanol concentration than the primary fermentation product. Brandy, whiskey, rum and Chinese white spirit all belong to distilled spirits, most of which are strong spirits with higher degrees. Distilled spirits familiar to modern people are classified as "white spirits" (also known as "distilled spirits"), "brandy," "whiskey," "vodka," "rum," and the like. White spirit is peculiar to China and is generally obtained by distilling grains after being brewed.

The liquor, the beer or the fermented grains are heated by a specially-made distiller, and the relative contents of various substances in steam and the liquor are different during heating distillation due to the different volatility of the various substances contained in the liquor, the beer and the fermented grains are heated by the specially-made distiller. Alcohol (ethanol) is more volatile, so that the concentration of alcohol in the vapor generated after heating is increased, and the concentration of alcohol in the wine liquid or the wine mash is decreased.

The distilled liquor needs to absorb a large amount of heat in the distillation kettle to reach the distillation temperature, but the distilled liquor has lower temperature and longer time spent on heat absorption before entering the distillation kettle for distillation, so that the distillation efficiency is reduced, the distilled liquor after distillation has higher temperature, special cooling equipment is needed for cooling, the heat of the distilled liquor is not utilized, the energy is seriously wasted, and the resource consumption is increased.
