Problems solved by technology

The colorless wine on the permeation side of the filter membrane is treated with an alcohol-permeable membrane to form high alcohol and alcohol-free water, and the non-alcoholic water dilutes the colored wine on the retentate side of the filter membrane to finally prepare alcohol-free wine, which solves the problem that heat-sensitive substances are easily destroyed , deterioration of easily oxidized components, etc.

preparation example Construction

[0052] like figure 1 The shown device for preparing non-alcoholic wine or strong wine includes a raw material tank, a middle tank, a filter membrane module and an alcohol-permeable membrane module,

[0053] The raw material tank outlet is connected to the membrane filter assembly, the permeate side outlet of the filter membrane module is connected to the intermediate tank, and the retentate side outlet of the filter membrane module is connected to the raw material tank, and the filter membrane module includes a nano filter membrane or decolorizing membrane,

[0054] The outlet of the intermediate tank is respectively connected to the raw material tank and the alcohol-permeable membrane module through valves, and the outlet of the retentate side of the alcohol-permeable membrane module is connected to the intermediate tank.

[0055] The base film of the decolorization film is a composite base film of polyethyleneimine (PEI), N-methylpyrrolidone (NMP) and LiCl, and the active l...

Embodiment 1

[0066] The original wine with an alcohol content of 8° is separated through the filter membrane module, and the operating temperature is 0.5°C. After the separation is completed, a primary filter permeate with an alcohol content of 8.2° is formed on the permeate side, and a primary filter with an alcohol content of 7.2° is formed on the retentate side. Filter the retentate, the weight of once filtered permeate / original wine is 0.8. The primary filtered permeate is separated through the pervaporation and permeation membrane module. Alcohols and alcohol-soluble aroma components are preferentially permeated through the membrane. The permeate side obtains the first high-alcohol wine with an alcohol content of 35°, and the retentate side obtains alcohol with an alcohol content of 0.1° Once through the alcohol retentate. The primary alcohol retentate and the primary filter retentate are mixed and diluted to form low-alcohol wine with an alcohol content of 4°.

[0067] Then the low-...

Embodiment 2

[0070] The original wine with an alcohol content of 12.5° is separated through a filter membrane module, and the operating temperature is 10°C. After the separation is completed, a primary filter permeate with an alcohol content of 12.8° is formed on the permeate side, and a primary filter with an alcohol content of 10.8° is formed on the retentate side. The retentate is filtered, and the weight of the once-filtered permeate / original wine is 0.85. The primary filtered permeate is separated through the pervaporation and permeable alcohol membrane module. Alcohols and alcohol-soluble aroma components are preferentially permeated through the membrane. The permeate side obtains the first high-alcohol wine with an alcohol content of 40°, and the retentate side obtains alcohol with an alcohol content of 0.2° Once through the alcohol retentate. The primary alcohol retentate and the primary filter retentate are mixed and diluted to form low-alcohol wine with an alcohol content of 5°. ...

Description

technical field [0001] The invention belongs to the technical field of brewing, and in particular relates to a device and a method for preparing non-alcoholic or high-alcohol wine by a double-membrane method. Background technique [0002] In recent years, low-alcohol and non-alcoholic beverages have shown a clear growth trend worldwide. Low-alcohol fever is beginning to appear, and at the same time, more and more non-alcoholic wines are entering China. On the other hand, brandy is usually called "the soul of wine". It is expensive and there are few types of domestic brandy. Because brandy has a fashionable appearance and the connotation of liquor, it can satisfy people's pursuit of life quality. To some extent, it will become Alternatives to liquor consumption. In this context, brandy will usher in a new era of development in the Chinese market. [0003] Patent CN109593619A proposes a system and method for simultaneously producing non-alcoholic wine and high-grade wine. T...
