Description

Technical Field

[0001] The utility model relates to wine-making technology, in particular to a machine for aging strong liquor. Background Art

[0002] High-concentration liquors have different tastes due to different fermentation raw materials, but the common feature is that newly produced liquors generally taste stronger. 98%-99% of the ingredients in high-concentration liquors are ethanol and water, which constitute the main body of the liquor. The other 1%-2% of the ingredients are mainly composed of trace amounts of organic acids, esters, fusel alcohols, aldehydes, ketones, phenols, sulfur-containing compounds, nitrogen-containing compounds, and extremely trace amounts of inorganic compounds (solids). They determine the aroma and taste of high-concentration liquors and constitute the typicality and style of high-concentration liquors. The types of trace ingredients (or flavor substances, aroma ingredients) and the content of each trace ingredient in the liquor are closely related to the raw materials and production processes used in the production of high-concentration liquors.

[0003] After aging in wine cellars and / or oak barrels, the taste of high-concentration spirits becomes softer. The main reason is that trace components in the wine, such as organic acids, fusel alcohols, aldehydes, ketones, phenols, etc., undergo chemical esterification reactions during the aging process in wine cellars and / or oak barrels, obtaining ester components and changing the taste. However, the traditional aging process in wine cellars and / or oak barrels takes a long time to complete the esterification reaction and achieve the esterification purpose.

[0004] Regarding the existing technology of liquor aging, Patent No. CN200910075686.X discloses a liquor aging process and device, which uses air, oxygen, ozone and other oxidizing agents to repeatedly pass into the liquor liquid to obtain a mellow-tasting liquor. The treatment lasts for 10-60 minutes, which is equivalent to the effect of natural aging for 1-3 years.

[0005] In the prior art of aging spirits, Patent No. CN201310440387.8 discloses a method for aging spirits, in which the molecular structure of the spirits is changed by heating, and the spirits are converted into small molecular clusters, so that the aldehydes in the spirits are continuously oxidized into carboxylic acids and undergo esterification reactions with alcohols, thereby changing the quality of the spirits.

[0006] In the prior art of liquor aging, Patent No. 201810597430.4 discloses a method for improving the quality of rice wine, which involves adding hypochlorous acid and potassium peroxide as oxidants into the wine to improve the quality of the rice wine through a redox reaction after exposure to light.

[0007] However, the above-mentioned prior art still has some deficiencies in the relevant functions actually used in the industry and needs to be improved. Therefore, the present invention proposes a solution. Summary of the invention

[0008] The main purpose of the utility model is to provide a wine aging device, which can be used to inject pure hydrogen and oxygen into the wine to alcoholize the fusel alcohols and aldehydes in the wine and convert them into alcohols and esters, thereby reducing the pungent smell and adjusting the pH value of the wine to weak alkalinity, effectively improving the taste of the wine. The wine aging device proposed by the utility model can also be used in small workshops and medium-sized and large wineries, and has industrial value.

[0009] To achieve at least one of the aforementioned advantages, the present invention provides a wine aging device, comprising a wine tank 700, a first pipeline 100, a second pipeline 200, a pump 600, a hydrogen supply device 400, a third pipeline 300, and a venturi 500.

[0010] The wine tank 700 has a wine inlet 710 for injecting external wine into the wine tank 700. The wine tank 700 includes a wine outlet 720 and a wine inlet 730. The wine outlet 720 outlets the wine in the wine tank 700 to the outside of the wine tank 700, and the wine inlet 730 inlets the wine into the wine tank 700.

[0011] The venturi tube 500 includes a fluid inlet 510 , a fluid outlet 520 , and a throat 530 . The fluid inlet 510 has a first tapered portion 511 toward the throat 530 . The venturi tube 500 also forms a gas inlet 531 in the throat 530 .

[0012] The hydrogen supply device 400 is connected to the gas inlet 531 of the venturi 500 through the third pipeline 300, and hydrogen is introduced into the venturi 500 through the gas inlet 531. One end of the first pipeline 100 is connected to the wine outlet device 720, and the other end is connected to the fluid inlet 510 of the venturi 500. The pump 600 is set at an appropriate position of the first pipeline 100 to pump the wine in the wine tank 700 into the fluid inlet 510.

[0032] The utility model mainly discloses a wine aging device, the winemaking principle involved in which is already understood by those with ordinary knowledge in the relevant technical field, so it will not be described in full below. At the same time, the accompanying drawings in the following text only express the structural schematics related to the utility model, and are not and do not need to be fully drawn according to the actual size, which is explained in advance.

[0033] In order to achieve at least one advantage of the utility model, the preferred embodiment of the utility model is a wine aging device, such as Figure 1 and Figure 2 shown.

[0034] The wine aging equipment includes a wine tank 700 , a first pipeline 100 , a second pipeline 200 , a pump 600 , a hydrogen supply device 400 , a third pipeline 300 , and a venturi 500 .

[0035] The wine tank 700 has a wine inlet 710, a wine outlet device 720 and a wine introduction device 730. The wine inlet 710 is used to inject the wine to be aged from the outside into the wine tank 700. The wine outlet device 720 guides the wine in the wine tank 700 to a device outside the wine tank 700 to inject clean hydrogen, and the wine introduction device 730 introduces the wine injected with clean hydrogen into the wine tank 700 for aging.

[0036] Please see Figure 3 and Figure 4 The venturi 500 includes a fluid inlet 510, a fluid outlet 520, and a throat 530. The fluid inlet 510 has a first tapered portion 511 toward the throat 530, and the venturi 500 also forms a gas inlet 531 at the throat 530. The cross-sectional area of ​​the fluid inlet 510 is relatively large, and the cross-sectional area of ​​the throat 530 is relatively small. When the high-pressure fluid enters from the fluid inlet 510 and flows to the throat 530, the cross-sectional area becomes smaller, the flow rate becomes faster, and the pressure is reduced. The external gas at the gas inlet 531 will be sucked in, and a large number of bubbles will be formed in the fluid at the downstream of the fluid inlet 510 due to turbulent stirring. The hydrogen supply device 400 of the utility model is connected to the gas inlet 531 of the venturi 500 through the third pipeline 300, and clean hydrogen is introduced into the wine in the venturi 500 through the gas inlet 531, so that a large number of hydrogen bubbles can be generated in the wine.

[0037] like Figure 4As shown, the throat 530 of the venturi tube 500 may also form a gradually opening second cone 521 toward the fluid outlet 520. By changing the taper and length of the first cone 511 and the second cone 521, the cross-sectional area and length of the throat 530, and the opening size of the gas inlet 531, the size and density of the bubbles may be adjusted. However, the utility model is not limited thereto, as long as the venturi tube 500 can inject clean hydrogen into the wine to generate hydrogen bubbles.

[0038] like Figure 1 As shown, one end of the first pipeline 100 is connected to the wine outlet device 720, and the other end is connected to the fluid inlet 510 of the venturi 500. The pump 600 is set at an appropriate position of the first pipeline 100 to pump the wine in the wine tank 700 into the fluid inlet 510. After the wine passes through the gas inlet 531, a large amount of clean hydrogen is mixed in. One end of the second pipeline 200 is connected to the fluid outlet 520 of the venturi 500, and the other end is connected to the wine introduction device 730, so that the wine mixed with a large amount of hydrogen bubbles can be introduced into the wine tank 700 for aging.

[0039] like Figure 6 As shown, for ease of manufacture, the wine tank 700 can be a barrel, whose cross section is roughly circular, the wine introduction device 730 has a first opening 731 facing the interior of the wine tank 700, and the wine outlet device 720 has a second opening 721 facing the interior of the wine tank 700. In order to improve the wine aging effect, after the wine with a large number of hydrogen bubbles passes through the venturi 500 and enters the wine tank 700 from the first opening 731 of the wine introduction device 730, it is best to be fully mixed with other wine in the wine tank 700. In other words, after the wine enters the wine tank 700 from the first opening 731 of the wine introduction device 730, it is best to slowly rotate and flow along the tank wall in the wine tank 700. Therefore, the fluid direction A1 of the first opening 731 is preferably not directly toward the cross-sectional center C of the wine tank 700. If it is directly toward the cross-sectional center C of the wine tank 700, the wine will have a smaller tendency to rotate and flow. If the extension line of the fluid direction A1 of the first opening 731 does not intersect with the cross-sectional center C of the wine tank 700, but presents an angle, even close to 90 degrees, toward the tangent direction of the tank wall, the wine will have a greater swirling flow in the wine tank 700. Similarly, the fluid direction A2 of the second opening 721 of the wine outlet 720 is preferably not toward the cross-sectional center C of the wine tank 700. If the extension line of the fluid direction A2 of the second opening 721 does not intersect with the cross-sectional center C of the wine tank 700, but presents an angle, even close to 90 degrees, toward the tangent direction of the tank wall, the wine will have a greater swirling flow in the wine tank 700, and the wine mixing effect will be better.

[0040] Hydrogen is the lightest gas in nature. After hydrogen is brought into the wine tank 700 by the wine through the wine introduction device 730, it will float up quickly. Therefore, the position of the second opening 721 is preferably as close to the bottom of the wine tank 700 as possible, thereby increasing the floating path of hydrogen in the wine tank 700, and the residence time of hydrogen in the wine can be increased. Similarly, the wine near the lower half of the wine tank 700 has a lower hydrogen content, and the wine near the upper half has a higher hydrogen content, so the position of the first opening 731 is also preferably as close to the bottom of the wine tank 700 as possible. In this way, the wine with a lower hydrogen content can be guided to the venturi 500 for hydrogenation.

[0041] In a preferred embodiment, the wine introduction device 730 and / or the wine outlet device 720 can be directly set by drilling holes in the wall of the wine tank 700 and then installing valve ports. Figure 1 shown.

[0042] However, if the existing wine tank structure is not to be destroyed, the wine introduction device 730 and / or the wine outlet device 720 can also extend into the wine tank 700 from the top of the wine tank 700 in the form of a pipeline 2, such as Figure 2 shown.

[0043] like Figure 5 As shown, in order to improve the efficiency of generating hydrogen bubbles, the venturi tube 500 may further be provided with a plurality of gas inlets 531 at the throat 530, which are distributed on the circumference of the tube wall of the venturi tube 500; preferably, the gas inlets 531 are evenly distributed in an annular shape.

[0044] Another key point of the present invention is that the hydrogen supply device 400 must supply pure hydrogen, especially pure hydrogen generated by pure water passing through a proton membrane electrolyzer, which cannot contain oxygen and cannot contain too much water vapor. Oxygen dissolved in the wine will acidify the wine and seriously affect the quality of the wine. Water vapor will dilute the ethanol concentration of the wine and affect the taste. There is a method of using sodium hydroxide electrolyte to electrolyze hydrogen. The water vapor contained in this hydrogen contains a strong alkaline component, which not only cannot age the wine, but is also harmful to the human body after drinking.

[0045] Figure 7 The figure shows an embodiment of a hydrogen supply device 400 for supplying pure hydrogen of the utility model. The hydrogen supply device 400 includes a water tank 47, an electrolysis device 45, a first flow channel 41, a second flow channel 42, a third flow channel 43, a heat sink 46, and a DC power supply 48.

[0046] The water tank 47 includes a water outlet 472 and a water oxygen inlet 473. The electrolysis device 45 is arranged on one side of the water tank 47, including a second water inlet 451, a water oxygen outlet 452 and a hydrogen outlet 453. A proton membrane electrolyzer is arranged inside the electrolysis device 45, and the water oxygen outlet 452 and the hydrogen outlet 453 are arranged on both sides of the proton membrane electrolyzer. The pure water in the water tank 47 enters the electrolysis device 45 through the water outlet 472, the first flow channel 41, and the second water inlet 451 for electrolysis. The proton membrane in the proton membrane electrolyzer is plated with anode metal and cathode metal as electrodes, and the pure water is electrolyzed to generate hydrogen and oxygen after power is turned on. Since the pores of the proton membrane are extremely small, only the hydrogen generated by the electrolysis of pure water can pass through the proton membrane to reach the other side and be discharged from the hydrogen outlet 453; the oxygen generated by electrolysis will not mix with the hydrogen. In this way, pure hydrogen without impurities can be supplied to other equipment for use. The water-oxygen mixture generated by electrolysis in the electrolysis device 45 enters the high-temperature water inlet 461 of the heat dissipation device 46 through the water-oxygen outlet 452 and the second flow channel 42. The water-oxygen mixture after heat dissipation flows out from the low-temperature water inlet 462, enters the water tank 47 through the third flow channel 43 and the water-oxygen inlet 473, and is recycled. The DC power supply 48 is electrically connected to the electrolysis device 45 and the heat dissipation device 46 to provide the power required for operation.

[0047] In order to reduce the water vapor content in the generated hydrogen, the hydrogen outlet 453 is also provided with a dehumidifier 454 to condense the water vapor and discharge it, or it can be introduced into the water tank 47 for continued use.

[0048] The wine aging equipment provided by the utility model generates bubbles of pure hydrogen in the wine through a venturi tube, and continuously introduces it into the wine tank to age the wine. For small wine tanks, the time for introducing hydrogen can be shortened; for large wine tanks, the amount of hydrogen introduced can be increased or the time for introducing hydrogen can be increased. After the introduction of hydrogen is completed, it is recommended to seal the wine tank for a period of time to allow the hydrogen in the wine to continue to age the wine, which can quickly alcoholize the fusel alcohols and aldehydes in the wine and convert them into alcohols and esters, thereby reducing the pungent smell and adjusting the pH value of the wine to a weak alkaline state, significantly improving the taste of the wine, reducing the discomfort caused to the human body by fusel alcohols and aldehydes in the wine, and greatly shortening the time required for the traditional aging process. The wine aging equipment provided by the utility model is easy to operate and use, safe, low in heat, and can be used continuously for a long time. It is suitable for use at home, in an office environment, and even in a factory.

[0049] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any technician familiar with the field can make equivalent implementations of equivalent changes using the methods and technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
