Description

Technical Field

[0001] This invention belongs to the field of rice wine processing, and specifically relates to an apparatus for preparing high-proof rice wine. Background Technology

[0002] Yellow wine is a traditional Chinese brewed wine with a long history and rich cultural connotations. It is made from grains such as rice, millet, black rice, corn, and wheat, through the addition of koji (fermentation starter) and yeast as saccharification and fermentation agents. Its alcohol content is approximately between 14% and 18%. Yellow wine is not only a fine wine but also a quintessence of Chinese culture and a culmination of traditional brewing techniques. It is extremely nutritious, containing 21 amino acids, including the eight essential amino acids for the human body, thus earning it the nickname "liquid cake." Yellow wine is not only a beverage but also an indispensable condiment in cooking.

[0003] Currently, rice wine accounts for less than 2% of the sales volume in the beverage market, indicating its limited market awareness and penetration. The main consumption area for rice wine is concentrated in the Jiangsu, Zhejiang, and Shanghai regions. Although rice wine has a long history and a wide audience, its dissemination and consumption remain limited to certain areas. In recent years, the rice wine industry has been attempting to adapt to the trend of consumption upgrading by improving product quality and moving towards high-end, youthful, and fashionable products. Because the current alcohol content of rice wine is only around 14%, it lacks a cost-performance advantage compared to traditional high-proof spirits, which limits its expansion into markets outside the Jiangsu, Zhejiang, and Shanghai regions. Currently, a common method to increase the alcohol content of rice wine is to blend it with distilled spirits. However, this method produces rice wine with drawbacks such as a harsh taste, an unnatural body, and insufficient aroma. Therefore, in recent years, some rice wine companies have begun to develop high-proof rice wines with a balanced body and rich aroma to improve their market competitiveness.

[0004] Pervaporation, as an energy-saving, environmentally friendly, and work-friendly membrane separation technology, boasts advantages such as high safety, simple process, low energy consumption, and high recovery rate. While there are reports on the application of pervaporation membranes in the processing of baijiu (Chinese liquor) and wine, their application in the processing of high-proof huangjiu (yellow rice wine) is still under development. Utility Model Content

[0005] To address the aforementioned technical shortcomings of high-proof Shaoxing wine, the applicant's research revealed that while simply concentrating or enriching the alcohol in Shaoxing wine can yield a high-proof spirit, it significantly alters the overall flavor of the wine. Therefore, this invention provides an apparatus for preparing high-proof Shaoxing wine. This apparatus utilizes pervaporation membrane separation technology, separating the raw Shaoxing wine into three parts: an organic permeate, a water permeate, and water, using different pervaporation membranes. Based on the overall flavor profile of the Shaoxing wine, the organic permeate and water permeate are blended in appropriate proportions to obtain the final high-proof Shaoxing wine. This process satisfies the requirements for increasing the alcohol content while preserving flavor compounds and the wine's characteristic taste.

[0006] To achieve the above-mentioned objectives, this utility model adopts the following technical solution: An apparatus for preparing high-proof rice wine includes a raw material tank 1, an organic permeable membrane assembly 5, and a water permeable membrane assembly 14. The raw material tank 1 is connected to the inlet of the permeable organic membrane module 5, and the permeate-side outlet of the permeable organic membrane module 5 is connected to the finished product tank 21 through the first flow controller 10 and the first valve 11. The permeable organic membrane assembly 5 has its permeate side outlet connected to the inlet of the permeable membrane assembly 14, and the permeate side outlet of the permeable membrane assembly 14 is connected to the finished product tank 21 via the second flow controller 19 and the second valve 20.

[0007] Furthermore, the membrane of the organic permeable membrane assembly 5 is a rice wine separation pervaporation composite membrane. The base layer of this membrane is prepared from cellulose acetate, dimethylacetamide, ethylenediaminopropylmethyldimethoxysilane, and polyethylene glycol 400, while the active layer is prepared from hydroxyl-terminated fluorosilicone oil, di(dimethylamino)methylvinylsilane, hydrogen-containing silicone oil, and chloroplatinic acid. This is prior art, described in CN110841490A.

[0008] Furthermore, the membrane material of the permeable membrane assembly 14 is PVA.

[0009] Furthermore, a first heater 4 is provided between the raw material tank 1 and the permeable organic membrane assembly 5 for heating the raw material.

[0010] Furthermore, an intermediate tank 2 is provided between the permeate side outlet of the organic permeable membrane assembly 5 and the inlet of the water permeable membrane assembly 14.

[0011] Furthermore, a second heater 13 is provided between the permeate side outlet of the organic permeable membrane assembly 5 and the inlet of the water permeable membrane assembly 14.

[0012] Furthermore, an organic permeate semi-finished product tank 8 is also provided between the permeate side outlet of the organic permeate membrane assembly 5 and the first flow controller 10.

[0013] Furthermore, an alcohol-free concentrate semi-finished product tank 17 is also provided between the permeable membrane assembly 14's permeate side outlet and the second flow controller 19.

[0014] Furthermore, the first flow controller 10, the first valve 11, the second flow controller 19, and the second valve 20 are electrically connected to the control system. The control system adjusts the first and second valves based on the flow feedback from the flow controllers to regulate the concentration of the target product.

[0015] Furthermore, the permeable membrane assembly 14 has its permeable side outlet connected to a water storage tank 22.

[0016] Furthermore, the organic permeable membrane assembly 5 or the water permeable membrane assembly 14 is supplied with a pressure differential by a vacuum pump.

[0017] Furthermore, a condenser is provided at the permeate-side outlet of the organic permeable membrane assembly 5 or the permeate-side outlet of the water permeable membrane assembly 14.

[0018] Furthermore, the organic permeable membrane assembly 5 or the water permeable membrane assembly 14 is composed of one or more membrane separators connected in series, in parallel, or in a series-parallel connection.

[0019] Furthermore, the membrane of the organic permeable membrane assembly 5 is tubular or plate-type.

[0020] Furthermore, the membrane of the permeable membrane assembly 14 is disc-shaped.

[0021] The beneficial effects of this utility model are as follows: (1) This utility model adopts a dual-membrane method, namely a combination of organic permeable membrane and water permeable membrane non-high temperature pervaporation technology to separate substances in rice wine. The high alcohol permeate is prepared by non-high temperature organic permeable membrane, and the alcohol-free concentrate is prepared by dehydrating the organic permeate residue using a non-high temperature water permeable membrane.

[0022] (2) The alcohol content of the permeate in the organic membrane and the nutrient concentration in the residual liquid of the water membrane can be adjusted arbitrarily according to specific needs.

[0023] (3) This utility model can obtain high-proof rice wine of 20-45% vol by adjusting the ratio of organic membrane permeate and water membrane permeate according to the specific taste and flavor, thus meeting the actual needs.

[0024] (4) No additives are added during the entire process of this utility model. It retains the flavor substances such as alcohol, ester, aldehyde, ketone, and sugar in the original wine, which can make the blended high-proof yellow wine balanced and natural and consistent with the overall style of the original wine. It can also blend high-proof yellow wine with a new style. Attached Figure Description

The product is mellow and rich in aroma, has a comfortable taste, and a balanced body. While retaining the style of the original wine, it increased the alcohol content and the content of components, thus meeting the market demand for high-proof rice wine.
