Description

Technical Field

[0001] This utility model relates to the field of irradiation equipment technology, and in particular to a pump-based circulating irradiation ripening device for wine. Background Technology

[0002] Many types of alcoholic beverages require a certain amount of time to develop their full flavor. Take baijiu (Chinese white liquor) as an example. Baijiu is a distilled spirit made primarily from grains. Newly brewed baijiu contains a high amount of volatile sulfur compounds, resulting in a pungent and spicy taste. After a period of aging, low-boiling-point substances in the baijiu gradually evaporate, and complex chemical reactions occur between alcohols, aldehydes, acids, and esters, gradually reducing its harshness and enriching its flavor. Traditionally, the aging process for baijiu takes years, increasing production costs due to space and capital constraints. To shorten the production cycle and accelerate aging, the industry has developed various aging technologies. Among them, ionizing radiation aging utilizes high-energy electron beams, gamma rays, and other ionizing radiation to irradiate the baijiu, generating a large number of ions and free radicals. These ions and free radicals interact with organic compounds, thus accelerating the aging process and improving the quality of the baijiu.

[0003] Existing technologies typically use electron accelerators or radioactive materials at irradiation stations as ionizing radiation sources to irradiate bottled or piped raw liquor. For example, CN218642707U involves transferring bottled liquor into a specially designed irradiation box, which then enters the electron beam irradiation area via a conveyor belt at the irradiation station; CN103305394A involves placing raw liquor in containers or pipes made of materials such as stainless steel, and then sending the containers into a 60Co-γ irradiation device for irradiation.

[0004] However, existing technologies may generate additional logistics and secondary packaging costs during concentrated irradiation, ionizing radiation may cause discoloration of bottled wine, affecting its aesthetics, and the lack of real-time monitoring methods during the irradiation process may lead to unstable wine quality.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0033] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0034] It should be emphasized that the term "including / comprises" as used herein refers to the presence of a feature, element, or component, but does not exclude the presence or addition of one or more other features, elements, or components.

[0035] It should also be noted that, unless otherwise specified, the term "connection" in this article can refer not only to a direct connection, but also to an indirect connection involving an intermediary.

[0036] In the following description, embodiments of the present invention will be illustrated with reference to the accompanying drawings. In the drawings, the same reference numerals denote the same or similar parts.

[0037] To address the issues of existing technologies, such as the additional logistics and secondary packaging costs during concentrated irradiation, the potential discoloration of bottled wine due to ionizing radiation affecting its aesthetics, and the instability of wine quality due to the lack of real-time monitoring during the irradiation process, a pump-based circulating irradiation maturation device for wines was designed, integrating a circulation system, irradiation device, detection device, and control module. This device can be used for the irradiation maturation of baijiu, red wine, and huangjiu.

[0038] Based on its operating principle, the structure of this invention can be divided into: a circulation system, which utilizes a pumping system to circulate the liquor between the storage tank and the aging device. The flow and diffusion of the liquid ensures thorough mixing of the irradiated liquor with the liquor in the storage tank. Multiple cycles achieve the effect of uniform aging of the liquor in the storage tank using a small-volume device. The irradiation device employs a modular design to reduce the difficulty of replacing the X-ray source. The X-ray source generates X-rays by bombarding a metal target with high-speed electrons generated by the cathode. It can use either a reflective X-ray source (i.e., the ray direction is on the same side as the cathode and target) or a transmission X-ray source. The detection device detects that the irradiation process causes some ethanol to convert to acetaldehyde and reduces the furfural concentration. Therefore, by sampling and measuring the absorption spectrum of the liquor, the concentration of the target substance (such as acetaldehyde or furfural) can be calculated using the differences in the absorption spectra of different substances in the liquor, allowing for online evaluation of the irradiation effect.

[0039] Furthermore, in some embodiments, a control module can be added to control the operating status of various valves and the wine pump in the circulation system, and to monitor the operating status of the radiation source (including tube voltage, tube current, cooling water flow rate and temperature, tank heating temperature, etc.). The module can also periodically control the detection device to return the concentration of the target substance in the wine. The irradiation process can also be started and stopped based on preset concentration thresholds or fault information from the radiation source.

[0040] Figure 1 This is a schematic diagram of the pumping circulation structure of a wine recycling irradiation ripening device according to one embodiment of this utility model. Figure 1 As shown, the wine circulation irradiation maturation device based on pumping proposed in this utility model includes a wine storage tank 101, and further includes: a wine pump 104 connected to the wine storage tank 101 via a pipeline, and an irradiation tank 205 connected to the other end of the wine pump 104 via a pipeline. The wine pump 104 is used to pump the wine from the storage tank 101 to the irradiation tank 205 located in the maturation zone 200. The irradiation device is used to generate X-rays, which are then used to irradiate the maturation zone 200.

[0041] The irradiation tank 205 is equipped with a sample inlet 206, a reflux inlet 207, and a discharge outlet 210. The reflux inlet 207 and the discharge outlet 210 are connected to the storage tank 101 via pipes. A reflux valve 105 is installed on the pipe near the storage tank 101, and a discharge valve 203 is installed on the pipe connecting the discharge outlet 210 to the storage tank 101 near the irradiation tank 205. It should be noted that the opening of the discharge outlet 210 must be positioned at the lowest point of the liquid level in the irradiation tank 205.

[0042] Accordingly, during the irradiation ripening process, the inlet 206 is used to allow the wine to enter the irradiation tank 205, and the reflux port 207 is used to allow the wine to flow back to the storage tank 101. The reflux valve 105 is kept open during the irradiation process. After the irradiation is completed, the remaining wine in the irradiation tank 205 is allowed to flow back to the storage tank 101 through the drain port 210 by opening the drain valve 203.

[0043] The wine circulation irradiation maturation device based on pumping proposed in this utility model, designed with X-rays as its foundation, can be built and used near the existing wine storage tanks of wineries. This avoids the logistics costs and secondary packaging costs caused by concentrated irradiation. Furthermore, the wine in the storage tanks is fully mixed during the maturation process. Compared with irradiating bottled wine or irradiating in pipelines before bottling, this helps ensure the consistency between wines of the same batch and avoids the problem of discoloration of bottled wine due to ionizing radiation, which affects the aesthetics.

[0044] In some embodiments of this utility model, such as Figure 1 As shown, the wine circulation irradiation maturation device further includes a pump valve assembly 103 installed on the pipeline connecting the wine storage tank 101 and the wine pump 104. The pump valve assembly 103 is used to regulate the start and stop of the wine pumping and the flow rate of the pumped wine. In some embodiments of this utility model, the wine circulation irradiation maturation device further includes a wine outlet valve 102 installed at the bottom of the wine storage tank 101, which allows the wine in the wine storage tank 101 to flow out.

[0045] By employing this embodiment, various valves can be designed to regulate the wine cyclic irradiation maturation process based on the wine cyclic irradiation maturation device proposed in this utility model, thereby ensuring the quality of the wine after maturation.

[0046] In some embodiments of this utility model, the height of the pipe connecting the wine storage tank 101 and the wine pump 104 is below the liquid level in the wine storage tank 101, and the height of the pipe connecting the reflux valve 105 is above the liquid level in the wine storage tank 101.

[0047] Using this embodiment, the wine can be circulated and irradiated without the need for an additional wine pump.

[0048] In some embodiments of this utility model, the wine circulation irradiation ripening device further includes a second wine pump installed at the outlet of the reflux port 207, the second wine pump being used to realize the return of wine from the irradiation tank 205 to the storage tank 101.

[0049] In this embodiment, by installing a second wine pump, the irradiated wine can be refluxed when the liquid level in the storage tank 101 is higher than the outlet of the reflux port 207 pipe.

[0050] Figure 2This is a schematic diagram of the structure of a wine recycling irradiation ripening device according to an embodiment of the present invention. It shows the structure of the irradiation device, including the shielding box 201, the radiation source 202, the radiation support 204, and the chiller 301, as well as some other structures included in the wine recycling irradiation ripening device.

[0051] In some embodiments of this utility model, such as Figure 2 As shown, the irradiation apparatus includes: a shielding box 201 that encloses the curing area 200 to prevent X-rays from leaking out of the shielding box 201; one or more X-ray sources 202 for generating X-rays; a X-ray support 204 for fixing the X-ray sources 202; and a chiller 301 for cooling the X-ray sources 202.

[0052] Optionally, the X-ray source 202 is a vulnerable X-ray source and adopts a modular installation method to reduce the difficulty of replacement and maintenance.

[0053] Using this embodiment, it is possible to safely generate and use X-rays for the irradiation and ripening of wine.

[0054] In some embodiments of this invention, when using the irradiation device, high voltage can be generated within the radiation source 202, or high voltage can be generated outside the radiation source 202 and then transmitted to the radiation source 202 via a high-voltage plug, thereby generating X-rays for irradiating the curing region 200. The radiation source 202 can be a point-shaped cathode radiation source, a linear cathode radiation source, a planar cathode radiation source, or a 60Co radiation source; wherein, the linear cathode of the linear cathode radiation source can be filamentary or spiral, and the planar cathode of the planar cathode radiation source can be a hot plate cathode, a cold plate cathode, or a cathode array. This solution is not limited to these; the types of radiation sources described above are merely examples and are not intended to limit the solution itself.

[0055] In practical implementation, for high-power radiation sources using linear cathodes (including filamentous and spiral cathodes) or planar cathodes (including hot plate cathodes, cold plate cathodes, and cathode arrays), in addition to the aforementioned vertical installation, a specialized irradiation tank and radiation support can be designed to insert the radiation source into the irradiation tank in a near-horizontal direction. This improves the heat dissipation capacity of the radiation source and makes full use of radiation from all directions. The inner wall of the irradiation tank adjacent to the radiation source is made of thinner materials such as stainless steel or titanium, and materials such as aluminum and beryllium, which have weak radiation absorption but may react with organic acids in the wine, are not used.

[0056] Using this embodiment, X-rays can be generated based on multiple radiation sources, and wine can be irradiated and matured based on different types of X-rays.

[0057] In practice, one or more radiation sources 202 can be pre-deployed above the irradiation tank 205, and the radiation sources 202 are fixed via modular interfaces on the radiation support 204. The shielding box 201 is used to prevent accidental radiation leakage.

[0058] In some embodiments of this utility model, a radiation source window is provided in the radiation support 204, and the radiation source window adopts a hollow or thin-layer structure.

[0059] This embodiment reduces the absorption of generated X-rays and facilitates the sealing of the irradiation vessel.

[0060] In some embodiments of this utility model, the shielding box 201 includes a lead plate and a pre-installed safety interlocking device.

[0061] Using this embodiment helps to improve the protective capability of the shielding box and further prevent accidental radiation leakage.

[0062] In some embodiments of this utility model, the wine cyclic irradiation ripening device further includes a detection device, which includes a spectrometer 302 and a detection valve group 305. The detection valve group 305 includes an upper solenoid valve installed in the pipeline between the wine pump 104 and the irradiation tank 205 and a lower solenoid valve installed in the pipeline between the wine pump 104 and the wine storage tank 101. The spectrometer 302 is installed between the upper solenoid valve and the wine pump 104. The spectrometer 302 detects the state of the wine by adjusting the opening and closing of the detection valve group 305.

[0063] In practical implementation, the upper pipe of the detection valve assembly 305 can be located outside the shielding box, between the wine pump and the irradiation tank, while the lower pipe can be located between the wine pump and the storage tank. During use, the upper solenoid valve of the valve assembly is opened, and some of the liquor pumped out by the wine pump flows into the spectrometer through the split pipe. After the sample chamber in the spectrometer is full, the upper solenoid valve is closed, and the light source is turned on and the spectrum is recorded after the liquor has stabilized. Then, the lower solenoid valve of the detection valve assembly is opened to empty the sample from the spectrometer, and the solenoid valve is closed. The spectrum of the empty sample is measured again to compensate for the long-term brightness drift of the light source. During measurement, the spectrometer mainly uses ultraviolet spectroscopy with wavelengths of 370nm-375nm to detect the furfural content in the liquor.

[0064] This embodiment allows for the introduction of monitoring methods during the irradiation process, enabling operators of the wine irradiation ripening device to monitor the wine's condition in real time and accurately determine the stopping time of the irradiation ripening process.

[0065] In some embodiments of this invention, the spectrometer 302 includes an ultraviolet (UV) spectrometer. In other embodiments, the spectrometer 302 includes both a UV spectrometer and a near-infrared (NIIR) spectrometer. The UV spectrometer is used to detect the furfural content in the wine, and the NIIR spectrometer is used to detect the acetaldehyde content in the wine. Optionally, the acetaldehyde content can be detected using a near-infrared spectrum with a wavelength of 1333 nm-1408 nm to improve the online monitoring capability of the irradiated wine.

[0066] Using this embodiment, acetaldehyde or furfural can be used as indicator substances to monitor the state of irradiated liquor and determine the stop time of the irradiation ripening process.

[0067] In some embodiments of this utility model, a stirring device is also provided inside the irradiation tank 205 for stirring the liquid inside the irradiation tank 205 during the X-ray process.

[0068] Using this embodiment, the liquor in the irradiation tank can be mixed more evenly, which helps to improve the consistency between liquors of the same batch.

[0069] In some embodiments of this invention, the wine cyclic irradiation ripening device further includes a heating belt 208 disposed below the irradiation tank 205. During the cyclic irradiation process, the heating belt 208 can be activated to heat the temperature of the tank body below the irradiation tank to a specified temperature.

[0070] This embodiment is advantageous in achieving high-temperature aging while utilizing thermal convection to reduce the prolonged deposition of some wine within the irradiation tank during the circulation process.

[0071] Optionally, if a certain type of baijiu is to be matured using this circulating irradiation aging device and then applied to other types of baijiu or no longer used in the short term, the heating belt 208 should be activated after removing the radiation source 202 and opening the exhaust port of the radiation source support 204. The tank temperature should be raised to above 60 degrees Celsius for at least 0.5 hours. This process allows residual liquor in the tank to evaporate, reducing the possibility of cross-contamination between different liquor samples and minimizing the corrosion of the tank by organic acids in the baijiu.

[0072] In some embodiments of this utility model, the wine recycling irradiation ripening device also includes a power distribution box 304, which is used to distribute power to the electrically driven parts of the wine recycling irradiation ripening device.

[0073] Figure 3 This is a schematic diagram of the structure of a wine circulation irradiation maturation device according to another embodiment of the present invention. In specific implementation, the wine circulation irradiation maturation device may further include a controller 209 for controlling the opening and closing of various devices and valves. Furthermore, the controller 209 can also be used to control and adjust the process parameters during the wine irradiation process. In addition, a touch screen 303 can be provided, which can display the wine state monitored by the detection device in real time, and also enable real-time human-machine interaction with the wine circulation irradiation maturation device.

[0074] The controller 209 controls the opening and closing of various devices and valves to ensure the normal operation of the alcoholic beverage irradiation and ripening device. Optionally, it can be used to adjust process parameters during the irradiation process of baijiu (Chinese liquor).

[0075] Figure 4This is a schematic diagram of the irradiation tank in one embodiment of the present invention. It is a funnel-shaped irradiation tank that is wider at the top and narrower at the bottom. Figure 5 The diagram below shows the structure of an irradiation tank in another embodiment of the present invention. It is a horizontally placed cylindrical irradiation tank.

[0076] like Figure 4 As shown, to ensure the wine fills the irradiation tank, the inlet 206 can be located at the top, middle, or bottom of the irradiation tank, while the reflux port 207 should be located at the top of the irradiation tank. To heat the wine, the heating belt must at least cover the lower half of the irradiation tank.

[0077] In practical implementation, the wine circulation irradiation maturation device proposed in this utility model can be modified based on the existing wine storage tank 101 in wineries, by adding two pipes to the storage tank 101. During the modification, the pipe connected to the pump valve assembly 103 needs to be below the liquid surface inside the tank, while the pipe connected to the return valve 105 needs to be above the liquid surface inside the tank. One end of the wine pump 104 is connected to the storage tank 101, and the other end is connected to the maturation zone 200. The wine pump 104 is used to pump new wine into the maturation zone 200 for irradiation treatment. The irradiated wine flows back to the storage tank through the return port, thus realizing the circulation treatment of the white wine in the storage tank. After irradiation, the pump valve assembly 103 can be closed, and the discharge valve 203 can be opened to empty the remaining wine sample in the irradiation tank into the storage tank. Figure 3 and Figure 4 The structure shown illustrates the process of liquor reflux: the liquor flows into the irradiation tank 205 from the inlet 206, and then flows back to the storage tank from the reflux inlet 207 through the reflux valve 105, thus achieving the circulation of the liquor in the storage tank. After irradiation, the pump valve assembly 103 is closed, and the discharge valve 203 is opened to empty the remaining liquor sample in the irradiation tank into the storage tank. Optionally, the inlet 206 in the irradiation tank can be located at the upper, middle, or lower part of the irradiation tank 205.

[0078] Optionally, the pipes used in this invention can be stainless steel corrugated pipes. Preferably, the wine pump 104 can be connected to the wine storage tank and the maturation zone 200 via stainless steel corrugated pipes.

[0079] To verify the effectiveness of this invention, an experiment was conducted using 1.0 ton of a certain brand of strong-aroma baijiu (Chinese liquor) for aging. The experimental parameters were as follows: the voltage of the three reflective X-ray source tubes was 160 keV, with a total power of 2.4 kW; online detection of furfural changes in the baijiu was performed using ultraviolet spectroscopy with wavelengths of 270 nm-275 nm; the control system was set to stop irradiation when the furfural content decreased by 40%; the actual continuous irradiation time was approximately 5 days.

[0080] The experimental results showed that the furfural content detected by gas chromatography-flame ionization detector decreased from 34.02 mg / L to 20.88 mg / L, an actual decrease of 38.6%. Furthermore, after manual tasting, the new wine tasted smoother after irradiation.

[0081] The proposed pump-based circulating irradiation maturation device for liquor, incorporating a small X-ray irradiation unit, can be constructed near existing storage tanks in wineries. This allows for in-situ maturation of baijiu (Chinese white liquor) within the winery, effectively avoiding the logistics and secondary packaging costs associated with centralized irradiation compared to existing methods that involve irradiating the liquor before it is stored in additional sealed containers. Furthermore, the liquor in the storage tanks is thoroughly mixed during the maturation process, ensuring consistency between batches compared to irradiating bottled liquor or irradiating it through pipelines before bottling. This also avoids the issue of bottle discoloration caused by ionizing radiation, which can affect the aesthetics of bottled liquor. Additionally, the detection device uses acetaldehyde or furfural in the baijiu as an indicator to determine the degree of maturation, improving wineries' ability to control the quality of irradiated liquor.
