Description

Technical Field

[0001] The present invention relates to the technical field of liquor treatment, and particularly relates to a liquor treatment device and method based on ultraviolet photocatalysis. Background Art

[0002] The flavor of liquor is one of the key factors determining its quality. Traditional methods for regulating liquor flavor mainly rely on raw material selection, fermentation process, and aging process, which have disadvantages such as long cycle and poor controllability. In recent years, photocatalysis technology, as an emerging liquor treatment technology, has shown good application prospects. By irradiating photocatalytic materials with ultraviolet light, active substances with strong oxidizing properties can be generated, thereby regulating flavor substances in liquor and improving liquor quality. However, most existing photocatalytic liquor treatment devices have problems such as poor liquor fluidity and small contact area with photocatalytic materials, resulting in low photocatalytic efficiency and unsatisfactory flavor regulation effect. Summary of the Invention

[0003] In order to overcome the defects existing in the above-mentioned prior art, the purpose of the present invention is to provide a liquor treatment device and method based on ultraviolet photocatalysis, which improves photocatalytic efficiency, effectively regulates flavor substances in liquor, and improves liquor quality.

[0004] To achieve the above object of the present invention, the present invention provides a liquor treatment device based on ultraviolet photocatalysis, comprising:

[0005] A container body for containing liquor, and a photocatalytic coating is provided on its inner wall;

[0006] An ultraviolet light source for irradiating the photocatalytic coating in the container body with ultraviolet light to catalyze the photocatalytic coating to generate active substances with strong oxidizing properties;

[0007] A stirring device disposed in the container body for making the liquor flow;

[0008] A control module, the control ends of the ultraviolet light source and the stirring device are respectively connected to the control module, and the control module controls the operation of the ultraviolet light source and the stirring device.

[0009] The liquor treatment device based on ultraviolet photocatalysis catalyzes the photocatalytic coating by the ultraviolet light source to generate active substances with strong oxidizing properties. These active substances oxidize pungent substances such as acetaldehyde and fusel oil in the liquor and convert them into mild components such as acetic acid and esters, which can effectively regulate flavor substances in the liquor; at the same time, the stirring device is used to promote the flow of the liquor, thereby accelerating the regulation speed of the liquor.

[0010] Optionally, the stirring device includes a stirring shaft and stirring blades disposed on the stirring shaft. The stirring shaft is connected to a rotating motor, and the control end of the rotating motor is connected to the control module.

[0011] Optionally, the stirring device is an ultrasonic generator, and its control end is electrically connected to the control module.

[0012] Optionally, the stirring device includes an electromagnet disposed outside the container body. The electromagnets are uniformly arranged along the height of the container body. A stirrer is arranged inside the container body. One side of the stirrer is a magnetic adsorbent, and the other side is a fan blade.

[0013] Optionally, the stirring device is a micro pump, and its control end is electrically connected to the control module.

[0014] Optionally, a photocatalytic coating is provided on the surface of the stirring paddle or the surface of the fan blade. This optional solution increases the photocatalytic coating area and can further accelerate the regulation speed of the liquor.

[0015] Optionally, the photocatalytic coating is a titanium dioxide coating. Ultraviolet light can excite titanium dioxide to generate electron-hole pairs, generating hydroxyl radicals and superoxide radicals. These radicals oxidize pungent substances such as acetaldehyde and fusel oil in the white liquor and convert them into mild components such as acetic acid and esters, thereby rapidly improving the flavor and taste of the liquor.

[0016] The present application also proposes a liquor treatment method. Based on the above-mentioned liquor treatment device based on ultraviolet photocatalysis, the liquor is treated as follows:

[0017] S1. Use a volatile substance detection device to detect the volatile substances in the liquor, calculate the initial pungency index of the liquor, let the initial pungency index be the pungency index L and transmit it to the controller;

[0018] S2. The control module calculates the required irradiation duration, required irradiation power of the ultraviolet light source, and the required movement speed of the liquor according to the pungency index L. The ultraviolet light source irradiates according to the required irradiation duration and required intensity, and the stirring device operates according to the required liquor movement speed to control the liquor movement speed;

[0019] S3. Calculate the degree of reduction in pungency ΔL. If the threshold is reached, exit. Otherwise, let L = L - ΔL, and re-execute step S2 until the liquor meets the requirements.

[0020] This liquor treatment method determines the required irradiation duration, required irradiation power of the ultraviolet light source, and the required movement speed of the liquor by calculating the pungency index, controls the ultraviolet light source to work at the required irradiation intensity, irradiates according to the required irradiation duration, and controls the stirring device to make the liquor move at the required liquor movement speed. This precise control of the ultraviolet light source and the stirring device improves the accuracy of liquor flavor regulation and can make the liquor flavor regulation effect continuously approach the ideal state.

[0021] Optionally, the initial spiciness index is:

[0022] α1C1 + α2C2 + α3C3 +...... + α n C n

[0023] where α1, ……, α n are the weight coefficients fitted according to experimental data, C1, ……, C n are the concentrations of volatile organic compounds detected by the volatile substance detection device, and n is the type of volatile organic compounds.

[0024] This optional solution calculates the initial spiciness index through multiple volatile organic compounds, improving the accuracy of the initial spiciness index, providing effective data for the flavor regulation of the liquor, and helping to improve the flavor regulation effect of the liquor.

[0025] Optionally, the method by which the control module calculates the required irradiation duration, required irradiation intensity of the ultraviolet light source, and required movement speed of the liquor is as follows:

[0026] t = k1×L + t0

[0027] P = k2×L + P0

[0028] V = k3×L + V0

[0029]

[0030] where t is the required irradiation duration of the ultraviolet light source, P is the required irradiation power, V is the required movement speed of the liquor, k1, k2, k3 are constants, t0 is the basic irradiation duration, P0 is the basic irradiation power, V0 is the minimum speed value, ΔL is the degree of reduction in spiciness, β is the photocatalytic efficiency, and γ is a constant term.

[0031] This optional solution can effectively improve the flavor regulation effect of the liquor through the accurate calculation of the required irradiation duration, required irradiation intensity of the ultraviolet light source, and required movement speed of the liquor.

[0032] The beneficial effects of the present invention are as follows:

[0033] 1. The structure of the present invention is simple, the production and manufacturing cost is low, and using this liquor treatment device can improve the photocatalytic efficiency, effectively regulate the flavor substances in the liquor, and improve the quality of the liquor.

[0034] 2. The present invention realizes the precise regulation of the liquor flavor and improves the quality of the liquor by detecting the liquor parameters in real time and dynamically adjusting the ultraviolet light irradiation parameters and the parameters of the stirring device according to the liquor parameters.

[0035] 3. The present invention adopts a method of multi-parameter combined control, comprehensively considering the influence of various flavor substances in the liquor, making the flavor regulation more comprehensive and balanced.

[0043] Embodiment 1

[0044] As Figure 1 shown, the present invention provides a liquor treatment device based on ultraviolet photocatalysis, including a container body, an ultraviolet light source, a stirring device, and a control module.

[0045] Among them, the container body is used to hold the liquor, and a photocatalytic coating is provided on its inner wall. The ultraviolet light source is arranged inside or on the top of the container body (preferably arranged on the top of the container body, such as inside the container lid), and is used to irradiate the photocatalytic coating, so as to catalyze the photocatalytic coating on the inner wall of the container body to generate active substances with strong oxidizing properties. These active substances oxidize pungent substances such as acetaldehyde and fusel oil in the liquor and convert them into mild components such as acetic acid and esters. The stirring device is arranged inside the container body and is used to make the liquor flow and accelerate the conversion of the liquor. The control ends of the ultraviolet light source and the stirring device are respectively connected to the control module, and the control module controls the operation of the ultraviolet light source and the stirring device.

[0046] In this embodiment, the stirring device can have various forms, and can adopt but is not limited to any one of the following:

[0047] The first type: The stirring device includes a stirring shaft and stirring blades arranged on the stirring shaft. The stirring shaft is connected to a rotating motor, and the control end of the rotating motor is connected to the control module. The control module controls the rotating motor to work, and the output shaft of the rotating motor drives the stirring shaft to rotate synchronously, so that the liquor flows.

[0048] The second type: The stirring device includes an electromagnet arranged outside the container body. The electromagnets are evenly arranged along the height of the container body. A stirrer is arranged inside the container body. One side of the stirrer is a magnetic adsorbent, and the other side is a fan blade. During operation, the controller controls the electromagnets outside the container body to be energized in sequence along the height direction, so as to adsorb and push the stirrer inside the container body to move along the height direction of the container body.

[0049] The third type: The stirring device uses an ultrasonic generator. The ultrasonic generator is preferably but not limited to being arranged at the bottom of the container. Its control end is connected to the control module, and the control module controls the ultrasonic generator to generate ultrasonic waves to promote the flow of the liquor.

[0050] The fourth type: The stirring device uses a micro pump. Its control end is connected to the control module for control, and the control module controls the micro pump to work to promote the flow of the liquor.

[0051] For the first and second types of stirring devices, a photocatalytic coating can be provided on the surface of the stirring blades or the fan blades to further accelerate the conversion of the liquor.

[0052] In this embodiment, a human-machine interaction module electrically connected to the control module is also provided. Through the human-machine interaction module, human-machine interaction can be realized, and personalized customization of the liquor flavor and the like can be achieved.

[0053] This embodiment preferably but not limited to uses titanium dioxide coating as the photocatalytic coating. Ultraviolet light excites titanium dioxide to generate electron-hole pairs, producing hydroxyl radicals and superoxide radicals. These radicals oxidize pungent substances such as acetaldehyde and fusel oil in baijiu, converting them into mild components such as acetic acid and esters, thereby rapidly enhancing the flavor and taste of the liquor.

[0054] Embodiment 2

[0055] Based on the liquor treatment device based on ultraviolet photocatalysis provided in Embodiment 1, this embodiment provides a liquor treatment method. As Figure 2 shown, the liquor is treated as follows:

[0056] S1, Use a volatile substance detection device (such as an electronic nose, which is equipped with a multi-channel polymer sensor array and / or an electrochemical sensor array, etc.) to detect the volatile substances in the liquor. The volatile substance detection device can be set on the container lid of the container body for real-time detection; the volatile substance detection device can also be external. When detection is required, open the container lid and use the volatile substance detection device to detect, and then cover the container lid after the detection is completed.

[0057] Then, calculate the initial pungency index of the liquor according to the volatile substances detected by the volatile substance detection device. In this embodiment, the initial pungency index is:

[0058] α1C1 + α2C2 + α3C3 +...... + α n C n

[0059] Where, α1, ……, α n are the weight coefficients fitted according to experimental data, C1, ……, C n are the concentrations of volatile organic compounds (such as acetaldehyde, acetone, isoamyl alcohol, n-butanol, ethyl acetate, etc.) detected by the volatile substance detection device (such as an electronic nose), and n is the type of volatile organic compounds.

[0060] If the volatile substance detection device is set on the container lid of the container body, then the volatile substance detection device is electrically connected to the control module, and sends the volatile substances it detects to the control module. The control module calculates the initial pungency index of the liquor according to the volatile substances. The control module takes the calculated initial pungency index as the pungency index L.

[0061] If the volatile substance detection device is external, the initial pungency index of the liquor can be calculated based on the volatile substances detected by the volatile substance detection device, and then the initial pungency index is set as the pungency index L and transmitted to the controller. Similarly, the volatile substance detection device can also be electrically connected to the control module, and the control module calculates the initial pungency index of the liquor according to the volatile substances detected by the volatile substance detection device, and uses the calculated initial pungency index as the pungency index L.

[0062] S2. The control module calculates the required irradiation duration, required irradiation power, and required liquor movement speed of the ultraviolet light source according to the pungency index L. The control module controls the ultraviolet light source to work at the required irradiation power, so that the ultraviolet light source irradiates according to the required intensity, and the timer in the control module synchronizes the timing, so that the ultraviolet light source irradiates for the required irradiation duration. When the irradiation duration reaches the required irradiation duration, the control module automatically turns off the ultraviolet light source; the control module controls the stirring device to operate according to the required liquor movement speed to control the liquor movement speed.

[0063] When the first stirring device in Embodiment 1 is adopted, the control module calculates the power P1 required to be output by the rotating motor according to the liquor movement speed, and drives the rotating motor to work at the required output power through the drive circuit. The output shaft of the rotating motor synchronously drives the stirring shaft to rotate, so that the liquor movement speed reaches the required liquor movement speed.

[0064] Wherein, T is the output torque of the motor (unit: N·m), V is the required liquor movement speed (unit: m / s), and r is the length of the stirring blade (unit: m).

[0065] When the second stirring device in Embodiment 1 is adopted, that is, an electromagnet is arranged outside the container body, the control module controls the energization switching frequency of the electromagnet according to the liquor movement speed, and adsorbs and pushes the stirrer in the container body to move along the height direction of the container body so that the liquor movement speed reaches the required liquor movement speed.

[0066] When the third stirring device in Embodiment 1, that is, an ultrasonic generator, is adopted, the control module calculates the power of the ultrasonic generator according to the liquor movement speed, and controls the ultrasonic generator to work at this power, and the emitted ultrasonic waves make the liquor movement speed reach the required liquor movement speed.

[0067] When the fourth stirring device in Embodiment 1, that is, a micro pump, is adopted, the control module calculates the power required to be output by the micro pump according to the liquor movement speed, and controls the micro pump to work at this power, so that the liquor movement speed reaches the required liquor movement speed.

[0068] The power required for the specific rotary motor, the energization switching frequency of the electromagnet, the power of the ultrasonic generator, and the power required for the micropump and the movement speed of the wine liquid (the movement speed of the wine liquid can be specifically measured by ultrasonic sensing, for example, by emitting ultrasonic waves to the surface of the wine liquid and detecting the echo, determining the frequency difference between the transmitted wave and the echo, and obtaining the movement speed of the wine liquid = (frequency difference * propagation speed of ultrasonic waves in the wine liquid) / transmission frequency) can be determined through experiments and the corresponding relationship can be stored in the controller.

[0069] In this embodiment, the required irradiation duration, irradiation intensity, and the required movement speed of the wine liquid of the ultraviolet light source are calculated according to the following formula.

[0070] t = k1×L + t0

[0071] P = k2×L + P0

[0072] V = k3×L + V0

[0073] Wherein, t is the required irradiation duration of the ultraviolet light source, P is the required irradiation power, V is the required movement speed of the wine liquid, k1, k2, and k3 are constants determined by experimental fitting, t0 is the basic irradiation duration, P0 is the basic irradiation power, V0 is the minimum speed value, which can be 0, and L is the pungency index.

[0074] S3. Calculate the degree of reduction in pungency ΔL.

[0075]

[0076] Wherein, β is the photocatalytic efficiency, which can be determined through experiments. Specifically, reference can be made to "Test Method for Aqueous Solution Purification Performance of Photocatalytic Materials" GB / T 23762-2020, and γ is a constant term (which can be determined by experimental fitting according to the specific wine liquid concentration, temperature, titanium dioxide dosage, etc.).

[0077] If the degree of reduction in pungency ΔL reaches the threshold value, then exit. Otherwise, let L = L - ΔL, and re-execute step S2 until the degree of reduction in pungency ΔL reaches the threshold value and the wine liquid meets the requirements.

[0078] After the wine liquid meets the requirements, turn off the ultraviolet light source and the stirring device, and take out the treated wine liquid.

[0079] In this embodiment, the setting of the threshold value is realized by sending a specific value to the control module through the human-machine interaction module, or a target flavor parameter can be sent to the control module through the human-machine interaction module, and the control module calculates the threshold value according to the target flavor parameter.

[0080] In the description of this specification, the descriptions referring to terms such as "one embodiment", "some embodiments", "examples", "specific examples", or "some examples", etc., mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
