White wine reduced pressure distillation system and distillation method

Abstract

The invention discloses a white wine reduced pressure distillation system. The white wine reduced pressure distillation system comprises a distillation steamer and a condenser communicated to the distillation steamer in a sealing manner; and the bottom of the condenser is connected to a wine liquid storage tank through a pipeline. The white wine reduced pressure distillation system also comprises a vacuum buffer tank and a vacuum pump; during a reduced distillation process, the distillation steamer, the condenser, the wine liquid storage tank and the vacuum buffer tank are successively communicated to form a sealed vacuum distillation system; and a vacuum pump communicated to the vacuum buffer tank provides a vacuum negative pressure environment for the vacuum distillation system. The invention also discloses a white wine reduced pressure distillation method. A technical solution provided by the invention can significantly reduce a temperature of distillation, and distill low-boiling point substances in soybean-flavor white wine out as many as possible by optimal arrangement of the reduced pressure distillation system and optimal combination of parameters of temperature and pressure during the reduced pressure distillation process. Besides, some high-boiling point substances that can not be distilled out at a normal pressure can be distilled out at the reduced pressure; composition of various ingredients in original fast wine is changed; and a unique flavor is formed.

Description

Technical field [0001] The present invention relates to the field of fermentation technology, in particular to a distilled spirit vacuum distillation system and a distillation method used in the wine industry. Background technique [0002] The boiling temperature of a liquid refers to the temperature at which the vapor pressure of the liquid is equal to the external pressure. When the external pressure decreases, its boiling temperature decreases accordingly. In the distillation operation, if the distillation device is connected to a set of decompression system, the pressure of the entire system is reduced to only one tenth to one tenth of the normal pressure before the distillation starts, then this kind of organic matter can be used. Distillation is carried out at a temperature much lower than its normal boiling point. The vacuum distillation method is widely used in the petrochemical industry, but less in the food industry. Soy-flavored liquor is a popular alcoholic product...

The vacuum distillation method is widely used in the petrochemical industry, but less in the food industry

Soy-flavored liquor is a popular alcohol product. In the prior art, this type of liquor is generally produced by atmospheric distillation. However, from the analysis of evaluation results, it is generally believed that Atmospheric pressure distillation is slightly strong, with a slight burnt aroma and miscellaneous taste, which cannot meet people's growing taste needs
