Description

Technical Field

[0001] The present invention relates to the technical field of wine aging and decanting, and more specifically, it relates to a decanting method based on a variable-frequency resonant variable electric field. Background Art

[0002] Wine decanting is a common processing method aimed at accelerating the oxidation reaction by promoting the contact between the wine liquid and oxygen, softening tannins, reducing astringency, and releasing aromas, thereby enhancing the flavor and taste of the wine. Traditional decanting methods mainly rely on natural exposure to air or increasing the contact area between the wine liquid and air through a decanter. However, this process usually takes a long time (from dozens of minutes to several hours), and the effect is limited by the type of wine and environmental conditions, making it difficult to meet the modern consumers' demand for rapid and efficient decanting.

[0003] Pulsed Electric Field (PEF) technology, as a non-thermal processing method, has been widely studied and applied in the food industry. In wine processing, PEF can achieve sterilization by applying short-term high-intensity electric field pulses (usually 1 - 50 kV / cm, pulse width in the microsecond to millisecond range), or accelerate the extraction of phenolic compounds in grape skins through electroporation. Existing research has shown that PEF treatment can significantly shorten the maceration time in wine brewing and promote the generation of volatile substances during the aging process, thus improving the aroma and softness of the wine. However, traditional PEF technology mostly uses contact electrodes to directly apply the electric field to the wine liquid, which is not suitable for portable consumption scenarios.

[0004] At the same time, ultrasonic technology also shows unique advantages in wine processing. The cavitation effect generated by ultrasonic high-frequency vibration (above 20 kHz) can accelerate the movement of molecules in the wine liquid, promote oxygen dissolution and chemical reactions. Research has shown that ultrasonic treatment can be used to accelerate the aging process of Chinese liquor or wine. For example, the variable-frequency ultrasonic wine aging device disclosed in the publication number CN105238660B, whose core idea is to use mechanical vibration to transfer energy to the wine body through variable-frequency ultrasonic waves in the sound guiding medium, hoping to accelerate aging. However, the action range of ultrasonic waves is limited, the energy transfer is easily affected by the container material and the volume of the wine liquid, and the wine flavor characteristics are changed due to local overheating, which limits its application in precise decanting.

[0005] In addition, electromagnetic field technology has also been explored for improving wine quality. Low-frequency or high-frequency electromagnetic fields (such as radio frequency or microwave) can change the distribution state of water, ethanol, and other volatile components in the wine liquid through molecular polarization and inductive heating effects. For example, the household wine electromagnetic aging device disclosed in the publication number CN2305406Y attempts to use high-frequency magnetic fields to act on the wine body, hoping to accelerate aging through the energy of the electromagnetic field. However, electromagnetic fields are usually accompanied by thermal effects, making it difficult to achieve fine control under non-thermal conditions.

[0006] Although the above-mentioned technologies have their respective advantages in liquor processing, they all have certain limitations: the contact design of PEF limits its portability and safety; the thermal effects and non-uniformity of ultrasonic waves and electromagnetic fields affect the flavor stability of liquor; existing methods mostly focus on industrial brewing or aging, rather than the rapid decanting demand directly facing the consumer side.

[0007] Based on this, it is necessary to be able to combine the dynamic regulation ability of pulsed electric fields, draw on the action characteristics of ultrasonic waves and electromagnetic fields, and at the same time achieve non-contact operation to meet the efficient decanting needs of different liquors in the consumption scenario. Summary of the Invention

[0008] For this reason, the purpose of the present invention is to provide a decanting method based on a variable-frequency resonant variable electric field, which uses an electric field within a specific frequency range to activate the liquor body in a short time by generating a polarization effect with liquor molecules, and accelerates the movement of liquor molecules and the rearrangement of charges.

BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Figure 1 is a schematic flow chart of the present invention;

[0035] Figure 2 is a schematic flow chart of the present invention based on Chinese liquor. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0036] Referring to Figure 1 - Figure 2 The decanting method of the present invention based on the variable electric field of variable frequency resonance will be further described:

[0037] The equipment used in this method includes an electric field generator, a waveform generator, and a sensor.

[0038] The electric field generator is responsible for generating a modifiable variable frequency resonance electric field, which is used to act on the wine body to be processed. Its structure is non-contact, and a circular magnetic ring is arranged outside the wine body container.

[0039] The electric field generator generates an alternating electric field according to the dynamic frequency signal and amplitude parameter provided by the waveform generator. The electric field frequency range is 1 - 500 kHz, and the amplitude range is 0 - 350 V.

[0040] The electric field generator adjusts the output frequency to make it close to or match the natural oscillation frequency of the wine body molecules (especially water molecules and alcohol molecules), thereby triggering the resonance effect. The resonance enhances the molecular polarization, resulting in an accelerated movement of the wine molecules, promoting the release of volatile substances and oxidation reactions.

[0041] The variable-frequency resonant electric field adopts an intermittent pulse modulation strategy. By precisely controlling the electric field action time (pulse width 1 - 5 ms) and the intermittent period (duty cycle 10% - 30%), the instantaneous heat generated by the wine molecules during the polarization process can be quickly dissipated, ensuring that the treatment process is always dominated by non-thermal effects.

[0042] The electric field generator receives the dynamic frequency (adjusted by a jump function) and amplitude parameters of the waveform generator in real time, and dynamically adjusts the electric field characteristics according to the changes in the vintage and alcohol content of the wine.

[0043] The jump function ensures that the frequency and amplitude change periodically within the set range, optimizing the decanting efficiency.

[0044] The waveform generator is the control unit of the electric field generator, responsible for generating dynamic frequency signals and amplitude parameters, and matching them with the body property parameters.

[0045] The waveform generator calculates the initial frequency and amplitude according to the input body properties (vintage, alcohol content) of the wine.

[0046] The initial frequency is generated by combining the fundamental frequency (5 - 20 kHz) and the frequency growth coefficient (10 - 100) with the vintage normalization parameter; the initial amplitude is generated by combining the amplitude growth coefficient (5 - 30) with the alcohol content normalization parameter.

[0047] The waveform generator realizes the jump adjustment of the frequency and amplitude: the frequency increases by 1 - 10 kHz per minute, reverses after rising from the lower limit (5 - 50 kHz) to the upper limit (200 - 500 kHz); the amplitude increases by 5 - 20 V per minute, reverses after rising from the lower limit (0 - 50 V) to the upper limit (150 - 350 V).

[0048] The adjustment process is controlled by a built-in algorithm to ensure that the electric field parameters change dynamically over time, providing precise dynamic electric field parameters to drive the electric field generator to generate a variable-frequency resonant electric field that meets the decanting requirements, ensuring personalized treatment for different types of wines (red wine, white wine, yellow rice wine).

[0049] The sensor is used to automatically obtain the property parameters of the wine body, including the type, vintage, and alcohol content of the wine. It can be integrated on the device or operate independently. The sensor converts the collected data into digital signals and transmits them to the waveform generator for calculating the normalization parameters.

[0050] By scanning the wine bottle label (QR code or barcode), the vintage and alcohol content information are extracted. If the sensor cannot recognize them, the user can manually input the parameters through the device interface.

[0051] Principle of device collaborative work: The sensor obtains the properties of the wine body (year, alcohol content), transmits them to the waveform generator. The waveform generator calculates the initial frequency and amplitude parameters and sends them to the electric field generator. The electric field generator generates a variable-frequency resonant electric field according to the dynamic signal of the waveform generator. The electric field acts on the wine body in the container, causing molecular polarization. Within 5 - 20 minutes, the electric field promotes the release of volatile substances and oxidation reactions, enhancing the aroma and improving the taste. The waveform generator adjusts the parameters in real time to ensure the best effect.

[0052] Example 1: Rapid decanting of wine (taking red wine as an example)

[0053] Step 1 is to obtain the property parameters of the wine body to be processed:

[0054] The user selects a bottle of Cabernet Sauvignon red wine from 2018.

[0055] By scanning the wine bottle label with the sensor on the device, the following property parameters are automatically obtained:

[0056] Type of wine: Wine (red wine); Year of wine (Y): 2018; Alcohol content (A): 13.8%.

[0057] Step 2 is to match the dynamic frequency signal and amplitude parameters according to the property parameters, and drive the electric field generator to generate a modifiable variable-frequency resonant electric field.

[0058] Determination of the initial frequency of the dynamic frequency signal: Set the base frequency f0 to 12 kHz (within the range of 5 - 20 kHz).

[0059] For wine, select the frequency growth coefficient k to be 80 (within the range of 20 - 100).

[0060] Set the lower limit Y of the year min to 2010, and the upper limit Y of the year max to 2020.

[0061] By calculating the normalized parameter based on the year , substituting the data, we get = 0.8. Based on 初始 = 0 + k × n, substituting the data, we get 初始 = 76 kHz.

[0062] Adjustment of the jump function of the frequency signal:

[0063] The frequency signal jumps between 10 kHz - 310 kHz, and the initial frequency is 初始 = 76 kHz.

[0064] The time step t starts from 0 and increases by 1 per minute. The frequency jump step is 5 kHz, and the frequency adjustment is carried out according to the following expression:

[0065] When the frequency does not reach the upper limit of 310 kHz: = min(310, 初始 + 5 × t); when the frequency reaches the upper limit of 310 kHz, switch the direction and reset t = 0: = max(10, 310 - 5 × t); when the frequency reaches the lower limit of 10 kHz, switch the direction again and reset t = 0: = min(310, 10 + 5 × t), and so on in a cycle.

[0066] Initialization of the amplitude of the modifiable electric field: Set the amplitude growth coefficient m to 15 (within the range of 5 - 30). Set the lower limit of the amplitude to 30 V (within the range of 0 V - 50 V). Set the upper limit of the amplitude to 250 V (within the range of 150 V - 350 V). Set the lower limit A of the alcohol content min to 12.0%, and the upper limit A of the alcohol content max to 15.0%.

[0067] Calculate the normalized parameter based on the alcohol content , and obtain = 0.6.

[0068] Calculate the initial amplitude , and obtain = 30 V.

[0069] Dynamic amplitude jump function adjustment: The amplitude jumps between 30 V and 250 V; the initial amplitude is = 30 V. The initial value of the amplitude jump step is set to 10 V (within the range of 5 V to 20 V).

[0070] The amplitude adjustment is carried out according to the following expression: When the amplitude does not reach the upper limit of 250 V: = min(250, current + 10); when the amplitude reaches the upper limit of 250 V, switch the direction: = max(30, 250 - 10); when the amplitude reaches the lower limit of 30 V, switch the direction again = min(250, 30 + 10), and so on in a cycle.

[0071] Driving electric field generator: The electric field generator generates a modifiable variable-frequency resonant electric field according to the above-mentioned dynamically changing frequency and amplitude parameters.

[0072] The third step is to accelerate the wine molecules through the electric field to complete the decanting process of the wine body:

[0073] The generated variable-frequency resonant electric field acts on the wine body. Through the polarization effect of the electric field and wine molecules (such as water molecules, alcohol molecules, flavor substance molecules, etc.), the movement of wine molecules is accelerated, the contact between oxygen and the wine liquid is promoted, and the redox reaction is accelerated, so as to achieve the purpose of decanting in a short time, making the aroma of the wine more released and the taste more mellow.

[0074] Based on Example 1 and the ultrasonic decanting method and the electromagnetic decanting method, decanting tests were carried out, and the test data are shown in Table 1:

[0084] For Chinese liquor, the frequency growth coefficient k is selected to be 130 (within the range of 80 - 150).

[0090] Adjustment of the dynamic wave amplitude jump function: The wave amplitude jumps between 40 V and 300 V; the initial wave amplitude is 初始 = 40 V. The initial value of the wave amplitude jump step is set to 15 V / minute.

[0091] Drive the electric field generator: The electric field generator generates an adjustable variable-frequency resonant electric field according to the above-mentioned dynamically changing frequency and wave amplitude parameters.

[0092] The third step is to accelerate the alcohol molecules through the electric field to complete the decanting process of the wine body:

[0093] The generated variable-frequency resonant electric field acts on the white wine, accelerating the movement of its molecules, which may promote the release and balance of flavor substances such as esters, reduce the pungency of new wine, and make the white wine taste more mellow and soft.

[0094] Based on the second embodiment and the ultrasonic decanting method and the electromagnetic decanting method, a decanting test is carried out, and the test data is shown in Table 2:

[0112] The third step is to accelerate the wine molecules through an electric field to complete the decanting process of the wine body:

[0113] The generated variable-frequency resonance electric field acts on the yellow rice wine, which may promote its esterification reaction, improve the flavor, remove possible peculiar smells, and make its taste more mellow.

[0114] Based on Example 3, decanting tests were carried out using ultrasonic decanting and electromagnetic decanting methods. The test data are shown in Table 3:
