Description

Technical Field

[0001] This utility model relates to the field of brewing equipment technology, and in particular to an aldehyde removal device for wine. Background Technology

[0002] With social development and continuous advancements in science and technology, people's living standards are constantly improving, and the demand for alcoholic beverages is also increasing. Therefore, wineries produce large quantities of various spirits, including baijiu, red wine, and huangjiu, every year to meet market demand. However, newly brewed spirits often contain high levels of tannins and aldehydes, resulting in a sour and astringent taste that is difficult to swallow. They require long periods of aging, and sometimes even the addition of animal proteins to soften the tannins and clarify the liquid, thus improving its taste and meeting bottling and market standards. Furthermore, the aldehydes in alcoholic beverages can be harmful to the human body. Excessive consumption of spirits containing excessive levels of formaldehyde and other aldehydes can damage a person's health.

[0003] To remove formaldehyde and other aldehydes from wine, Chinese utility model patent application No. 202311553538.0 discloses "a method for removing formaldehyde from wine." This method involves pouring the wine into a filter cartridge, placing a filter funnel at the bottom of the cartridge, adding packing material to the funnel, and placing a small molecular sieve at the bottom of the funnel to adsorb and filter the wine. The filtered wine is then transferred to a clean container, mixed with a catalyst, and placed in a heated water bath for heat absorption. During heating, the mixture is stirred to accelerate formaldehyde volatilization, and oxygen is introduced into the wine through an aeration device to induce an oxidation-reduction reaction. After the oxidation-reduction reaction, a corresponding amount of zeolite is weighed, washed, and added to the wine container to adsorb the formaldehyde. The wine is then stored in a sterile environment. After storage, the zeolite is removed, and the formaldehyde content in the wine is tested. If the formaldehyde content is within acceptable limits, the wine is bottled.

[0004] The above-mentioned methods for removing formaldehyde from alcoholic beverages are complex to operate and require a large amount of filter material during the production process, which significantly increases the production costs of alcoholic beverage manufacturers and greatly reduces their competitiveness in the market.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] Reference Figures 1 to 7 and mainly refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 According to certain embodiments of the present invention, an aldehyde removal device for wine is provided, which is sometimes referred to as "aldehyde removal device". An aldehyde removal device for wine includes a wine container 100, a reaction vessel 200, and one or more light source components. In this embodiment, the wine container 100 is generally cylindrical and is used to hold wine. The wine container 100 is provided with an outlet pipe 110 and an inlet pipe 120, both of which are connected to the interior of the wine container 100. A delivery pump body 130 is provided in either the outlet pipe 110 or the inlet pipe 120. The reaction vessel 200 is located on one side of the wine container 100 and has a reaction chamber 210 inside. The end of the inlet pipe 120 away from the wine container 100 is connected to the reaction chamber 210, and the end of the outlet pipe 110 away from the wine container 100 is connected to the reaction chamber 210. By adopting the above structure, the wine container 100, the outlet pipe 110, the reaction vessel 200, and the inlet pipe 120 are connected in series to form a circulating flow channel for the wine. Each light source assembly includes a light-transmitting sleeve 300 and a light source. In this embodiment, the light-transmitting sleeve 300 is a transparent glass tube or a light-transmitting quartz tube. The light-transmitting sleeve 300 is installed inside the reaction chamber 210 of the reaction container 200. The light-transmitting sleeve 300 contains a receiving cavity 310 that is isolated from the reaction chamber 210; that is, the receiving cavity 310 and the reaction chamber 210 are not connected. When the liquid is delivered into the reaction chamber 210, the liquid can only be located outside the light-transmitting sleeve 300. The light source is located inside the receiving cavity 310, and the wavelength range of the light generated when the light source is energized is 160nm-180nm. In this embodiment, the light source can be a hydrogen lamp, a deuterium lamp, or an excimer lamp. When the light source is energized and emits light, the light generated by the light source can pass through the side wall of the light-transmitting sleeve 300 and illuminate the inside of the reaction chamber 210.

[0032] Because aldehydes such as formaldehyde (HCHO) and acetaldehyde (CH3CHO) contain carbon-oxygen double bonds in their molecular structure, and these bonds have relatively low bond energies, photons of light with wavelengths of 160nm-180nm have high energy. When this light shines on an aldehyde molecule, the photon energy is transferred to the molecule, causing the chemical bonds to break. For example, the carbon-oxygen double bond in a formaldehyde molecule breaks under the influence of high-energy photons, generating methyl radicals (CH3·) and hydroxyl radicals (OH·). These radicals further react to ultimately produce carbon dioxide and water.

[0033] In this embodiment, the formaldehyde removal device connects the wine container 100 and the reaction container 200 through an outlet pipe 110 and an inlet pipe 120 to form a circulation loop. A light-transmitting sleeve 300 is installed in the reaction chamber 210 of the reaction container 200. A light source capable of emitting light with a wavelength of 160nm-180nm is installed in the receiving cavity 310 of the light-transmitting sleeve 300 when energized. Therefore, the delivery pump 130 transports the wine loaded inside the wine container 100 along the outlet pipe 110 to the reaction chamber 210 of the reaction container 200. When the light source is energized, the light emitted passes through the side wall of the light-transmitting sleeve 300 and illuminates the wine container. The wine is introduced into the reaction chamber 310, where light can break down formaldehyde and / or acetaldehyde in the wine, converting them into hydrogen ions, carbon monoxide, water, carbon dioxide, methyl groups, or methane. The irradiated wine is then transported back to the wine container 100 through the inlet pipe, and this cycle continues. The light source is powered on and continues to emit light, thus continuously breaking down formaldehyde and / or acetaldehyde in the wine. This not only effectively removes formaldehyde and / or acetaldehyde from the wine but is also low-cost, helping to improve the company's competitiveness.

[0034] To enable the formaldehyde removal device to better remove formaldehyde from the wine inside the wine container 100, in some embodiments of this invention, the formaldehyde removal time for the wine inside the wine container 100 ranges from 100 to 150 hours. Specifically, the formaldehyde removal device removes formaldehyde from the wine inside the wine container 100 for 120 hours. By adopting the above technical solution, the formaldehyde removal device achieves a better formaldehyde removal effect on the wine inside the wine container 100.

[0035] The following is a comparison of the quality test results of the same wine before and after formaldehyde removal treatment using the formaldehyde removal device according to certain embodiments of this utility model:

[0036]

[0037]

[0038] As can be seen from the above comparison results, the aldehydes in the wine are significantly reduced after being removed by the aldehyde removal device of certain embodiments of this utility model, and the aldehyde removal effect is good.

[0039] To enable the light emitted by the light source to better decompose substances such as formaldehyde and / or acetaldehyde, in some embodiments of this invention, the wavelength of the light generated when the light source is powered on is 172nm. Specifically, the light source is an excimer lamp. By using an excimer lamp as the light source, the excimer lamp can emit light with a wavelength of 172nm when powered on. Light with a wavelength of 172nm has higher energy. Therefore, when the light with a wavelength of 172nm irradiates aldehydes such as formaldehyde and / or acetaldehyde in the wine, the light can better decompose the aldehydes such as formaldehyde and / or acetaldehyde. The decomposition effect is not only better, but also more efficient, which helps to improve the efficiency of the aldehyde removal device in removing aldehydes from the wine in this embodiment, and further enhances the enterprise's social competitiveness. Since the excimer lamp, hydrogen lamp, or deuterium lamp mentioned above are known technologies in the art and can all be purchased commercially, they will not be described in detail.

[0040] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 To ensure that the light emitted by the energized light source can more efficiently irradiate the wine inside the reaction chamber 210, in some embodiments of this invention, the light source is disposed in the receiving cavity 310 of the light-transmitting sleeve 300, and the receiving cavity 310 is in a vacuum state. With this structure, when the light source is energized, the emitted light passes through the side wall of the light-transmitting sleeve 300 and irradiates the wine inside the reaction chamber 210. Since the receiving cavity 310 is in a vacuum state, the light emitted by the light source will not react with the air, thus minimizing the energy loss of the light. Therefore, the light emitted by the energized light source can carry more energy and irradiate the wine inside the reaction chamber 210, thereby allowing the light to better break down aldehydes in the wine.

[0041] To enable the light emitted by the energized light source to more efficiently remove aldehydes from the wine, in some embodiments of this invention, the light source is positioned within the receiving cavity 310 of the light-transmitting sleeve 300, and the receiving cavity 310 is filled with an inert gas, such as nitrogen, helium, neon, argon, or krypton. With this structure, when the light source is energized, the emitted light passes through the side wall of the light-transmitting sleeve 300 and irradiates the wine inside the reaction chamber 210. Since the receiving cavity 310 of the light-transmitting sleeve 300 is filled with an inert gas, the light emitted by the light source will not react with the inert gas inside the receiving cavity 310, and the energy of the light is essentially not consumed. Therefore, the light can carry more energy and irradiate the wine inside the reaction chamber 210, thereby better breaking down the aldehydes in the wine and achieving a more effective removal of aldehydes.

[0042] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 To simplify the structure of the formaldehyde removal device, in some embodiments of this invention, the reaction container 200 is elongated and arranged vertically on one side of the wine container 100. One end of the outlet pipe 110 is connected to the lower part of the wine container 100, and the other end is connected to the lower part of the reaction chamber 210. One end of the inlet pipe 120 is connected to the upper part of the reaction chamber 210, and the other end is connected to the upper part of the wine container 100. By adopting the above structure, the layout of the formaldehyde removal device in this embodiment is more reasonable and the structure is more compact, which helps to reduce the size of the formaldehyde removal device and facilitates its production and manufacturing.

[0043] To facilitate the installation of the light source assembly into the reaction chamber 210 inside the reaction vessel 200, in some embodiments of this invention, the upper part of the reaction vessel 200 is provided with an opening 220 communicating with the reaction chamber 210, and the upper part of the reaction vessel 200 is provided with an upper cover plate 230 capable of sealing the opening 220. The upper part of the light-transmitting sleeve 300 passes through the upper cover plate 230 and extends to the outside of the reaction chamber 210. By adopting the above structure, it is easier for enterprises to install the light-transmitting sleeve 300 of the light source assembly into the reaction vessel 200, making assembly simpler.

[0044] To improve the efficiency of the aldehyde removal device in removing aldehydes from wine, in some embodiments of this invention, the number of light source components is three sets. The light-transmitting sleeves 300 of the three sets of light source components are arranged alternately inside the reaction chamber 210, and the upper parts of the three light-transmitting sleeves 300 all pass through the upper cover plate 230 and extend to the outside of the reaction chamber 210. By adopting the above structure, when the aldehyde removal device of this embodiment is working, the three light sources of the three sets of light source components can simultaneously illuminate the wine inside the reaction chamber 210, thus effectively increasing the speed at which light breaks down aldehydes, and thereby greatly improving the efficiency of the aldehyde removal device in removing aldehydes from wine.

[0045] Reference Figure 6 and Figure 7 To facilitate the upper part of the light-transmitting sleeve 300 passing through the upper cover plate 230 of the reaction vessel 200, the surface of the upper cover plate 230 is provided with a number of clearance holes 231 equal to the number of light-transmitting sleeves 300, and the light-transmitting sleeves 300 are correspondingly inserted into the clearance holes 231. In some embodiments of this utility model, the surface of the upper cover plate 230 is provided with three clearance holes 231 at intervals. When the light-transmitting sleeves 300 of the three light source assemblies are installed inside the reaction chamber 210, the upper parts of the three light-transmitting sleeves 300 are correspondingly inserted into the three clearance holes 231, so that the upper parts of the three light-transmitting sleeves 300 extend to the outside of the reaction vessel 200, which facilitates the electrical connection between the external power supply circuit and the light source in the receiving cavity 310 inside the light-transmitting sleeve 300.

[0046] Reference Figure 1 , Figure 2 and Figure 3 To better position the reaction vessel 200, some embodiments of the formaldehyde removal device of this utility model further include a frame 400, located on one side of the wine container 100. A support platform 410 is provided on the upper part of the frame 400, and the reaction vessel 200 is mounted on the support platform 410. By adopting the above structure, the reaction vessel 200 is mounted on the support platform 410, thus making the placement of the reaction vessel 200 more stable and less prone to tipping over.

[0047] In some embodiments of this utility model, a protective cabinet 420 is provided on the upper part of the frame 400, and an installation cavity 421 is provided inside the protective cabinet 420. The protective cabinet 420 covers the outer periphery of the support platform 410, and the reaction container 200 is located inside the installation cavity 421. By adopting the above structure, the reaction container 200 is located inside the protective cabinet 420, which can prevent external objects from colliding with and contacting the reaction container 200, thereby preventing the reaction container 200 from being accidentally displaced or falling, which helps to protect the reaction container 200. This makes the formaldehyde removal device of this embodiment less susceptible to damage from external collisions and improves the anti-interference capability of the formaldehyde removal device of this embodiment.

[0048] In some embodiments of this utility model, the side wall of the protective cabinet 420 is provided with an inlet and outlet communicating with the mounting cavity 421. A cabinet door 422 capable of opening or closing the inlet and outlet is movably installed on the side wall of the protective cabinet 420. The delivery pump 130 is disposed on the liquid outlet pipe 110 and mounted on the support platform 410. By adopting the above structure, the protective cabinet 420 can protect the delivery pump 130 and the reaction vessel 200, further improving the anti-interference capability of the formaldehyde removal device in this embodiment.

[0049] In some embodiments of this utility model, a liquid outlet channel 101 for sampling is provided in the lower part of the side wall of the wine container 100. The liquid outlet channel 101 is provided with a first switch valve body capable of opening or closing the liquid outlet channel 101. When the user opens the first switch valve body, the wine inside the wine container 100 can flow out through the liquid outlet channel 101 to the user's sampling container. By adopting the above structure, after the aldehyde removal device of this embodiment has been working to remove aldehydes from the wine for a period of time, the user can open the liquid outlet channel 101 and take a sample. The user can test the sample to determine whether the content of aldehydes in the wine has reached the set value. If the test result of the sample does not reach the set value, the aldehyde removal device continues to start to remove aldehydes from the wine. If the test result of the sample reaches the set value, the user can take out the wine from the wine container 100 to replace another batch of wine that needs to be de-aldehyde removed.

[0050] Each time the wine is filled into the wine container 100, some air remains on the top of the inner wall of the container. Over time, the oxygen or oxygen ions in this air dissolve into the wine, and the oxygen decomposes into oxygen ions, which oxidize the wine, causing it to turn sour and severely affecting its taste. To prevent the wine inside the wine container 100 from oxidizing, some embodiments of this invention include an inert gas replenishment source for the formaldehyde removal device. The upper part of the wine container 100 is provided with a first air inlet channel 140 and a first air outlet channel 150. The inert gas replenishment source is provided with a gas supply pipe connected to the first air inlet channel 140, and the gas supply pipe is provided with a second switch valve body. The first air outlet channel 150 is provided with a third switch valve body. Specifically, the inert gas replenishment source includes a gas storage tank, which stores inert gas under compression. In this embodiment, the inert gas stored in the gas storage tank is nitrogen. The gas storage tank is connected to the first air inlet channel 140 of the liquor container 100 via a gas supply pipe. When the liquor container 100 is replaced, the user can open the third switch valve, which opens the first air outlet channel 150. The user can then open the second switch valve to open the gas supply pipe. At this time, the gas storage tank is connected to the inside of the liquor container 100 via the gas supply pipe and the first air inlet channel 140. The compressed nitrogen inside the gas storage tank can be transported into the inside of the liquor container 100 along the gas supply pipe and the first air inlet channel 140. As the nitrogen is continuously transported into the inside of the liquor container 100, it can expel the air at the top of the inner wall of the liquor container 100 through the first air outlet channel 150 until all the air inside the full liquor container 100 is expelled. After that, the user closes the third and second switch valves. By adopting the above structure, after each replacement of the wine, the user can open the third switch valve and the second switch valve, so that the inert gas supply source can deliver inert gas to the wine container 100 and expel the residual air inside the wine container 100, thus solving the technical problem that the oxygen or oxygen ions in the residual air inside the wine container 100 will dissolve in the wine and oxidize the wine.

[0051] To facilitate the efficient delivery of the inert gas stored in the gas storage tank to the wine container 100, in some embodiments of this invention, an air pump is installed in the gas delivery pipe connecting the gas storage tank to the first air inlet channel 140. When it is necessary to deliver the inert gas stored in the gas storage tank into the wine container 100, the user can open the third and second switch valves, and then the air pump will start working, continuously delivering the inert gas stored in the gas storage tank into the wine container 100. By adopting the above structure, the inert gas stored in the gas storage tank can be delivered into the wine container 100 more quickly, resulting in higher efficiency.

[0052] It should be noted that in the above embodiments, the inert gas stored inside the gas storage tank is nitrogen. However, in other embodiments of this utility model, the inert gas stored inside the gas storage tank can be other gases, such as helium, neon, argon, or krypton, depending on the actual needs.

[0053] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
