Description

Technical Field

[0001] This utility model relates to the field of liquor aging technology, specifically a liquor aging device. Background Technology

[0002] A baijiu aging device is a mechanical device used to accelerate the aging of baijiu and improve its quality. Its core function is to simulate the natural aging process through physical or chemical means, shorten the aging period of new baijiu, and improve its taste and flavor.

[0003] For example, an existing Chinese patent (CN212174927U) discloses an aging device for promoting the quality improvement of baijiu (Chinese liquor), comprising: a tank, ceramic columns, a stirring device, an inlet pipe, and an outlet pipe; the ceramic columns are disposed inside the tank, the ceramic columns are hollow, and the hollow parts of the ceramic columns are connected to the inside of the tank; the stirring device extends into the tank; the inlet pipe is connected to the tank; the outlet pipe is also connected to the tank. This device is simple to operate and highly practical. Compared with natural aging, by periodically magnetically stirring the liquor, the dynamic balance between ethanol and water molecules is continuously broken, accelerating Brownian motion, which has a very good promoting effect on the aging of new liquor. The ceramic columns inside the tank have oxidizing and adsorption effects, and the unique "micro-oxygen" environment formed between multiple ceramic columns and the "breathing" effect of the liquor in the tank can accelerate the aging of baijiu during storage and effectively shorten the aging time of baijiu.

[0004] The above-mentioned technical solution uses magnetic stirring to accelerate the aging of the wine, but it cannot filter out substances that cause turbidity and precipitation, such as solids and esters that re-turbid at low temperatures. These impurities can easily cause a bitter taste in the wine and affect its quality. Utility Model Content

[0005] The purpose of this invention is to provide a device for accelerating the aging of baijiu (Chinese liquor) to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for accelerating the aging of baijiu (Chinese liquor), comprising: an aging tank, a top shell located at the center of the top cover of the aging tank, a hollow shaft located at the center of the top shell, a drive motor fixed to the top of the top shell, a centrifugal cylinder fixed to the bottom end of the hollow shaft, a first filter membrane located on the inner wall of the centrifugal cylinder, a support plate fixed to the inner wall of the lower half of the aging tank, a filter cylinder located at the center of the support plate, a second filter membrane located on the inner wall of the filter cylinder, a liquid inlet hole opened on the outer wall of the top end of the hollow shaft, and a feed valve located on one side of the top shell.

[0007] Furthermore, it also includes a wine storage tank, with an output pipe at the bottom of one side of the wine storage tank. One end of the output pipe is connected to the feed valve on one side of the top shell, and an output pump is provided on the output pipe.

[0008] Furthermore, a discharge valve is provided at the bottom of one side of the aging tank, a return pipe is provided at one end of the discharge valve, a return pump is provided on the return pipe, and one end of the return pipe is connected to the inside of the storage tank.

[0009] Furthermore, one end of the output shaft of the drive motor is fixed to the top of the hollow shaft.

[0010] Furthermore, a feeding valve and a temperature sensor are provided on one side of the top of the aging tank, and the temperature sensor's probe can extend to the bottom area of ​​the aging tank. A feeding valve and a temperature sensor are also provided on the top of the storage tank.

[0011] Furthermore, an ultrasonic transducer is provided at the center of the bottom of the aging tank.

[0012] Furthermore, the first filter membrane is a ceramic filter membrane, and the second filter membrane is a polytetrafluoroethylene filter membrane.

[0013] Furthermore, both the centrifugal cylinder and the filter cylinder have mesh openings on their side walls.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, through the design of a storage tank, an aging tank, and a centrifugal cylinder, enables the aging of baijiu (Chinese white liquor). During aging, the liquor from the storage tank is pumped into the top shell via an output pipe using an output pump. The liquor then enters the centrifugal cylinder through an inlet hole at the top of a hollow shaft. A drive motor rotates the hollow shaft, centrifugally filtering the liquor. The filtered liquor then enters the support plate and, under gravity, enters the filter cylinder for secondary gravity filtration through a second filter membrane. This secondary filtration removes impurities, eliminates turbidity and off-flavors, and accelerates aging. The filtered liquor then returns to the storage tank via a return pipe and a return pump. This filtration process can be repeated several times.

[0016] In addition, during the filtration process, high-frequency ultrasonic waves can be generated by an ultrasonic transducer to produce tiny bubbles in the wine and break them rapidly, forming shock waves. This causes large molecules such as proteins and fats to decompose into smaller molecules, accelerating the generation and balance of aroma substances such as esters and alcohols, making the wine more mellow.

[0017] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a device for accelerating the aging of baijiu (Chinese liquor), comprising: an aging tank 8, with a top shell 9 located in the center of the top cover of the aging tank 8. The aging tank 8 serves as the core container, providing a sealed space for the aging of baijiu; the top shell 9 serves as the initial channel for the liquor to enter, and is connected to the output pipe 7 to form a liquor circulation path, ensuring that the liquor can be repeatedly processed.

[0025] A hollow shaft 11 is located in the center of the top shell 9, and a drive motor 10 is fixed to the top of the top shell 9. A centrifugal cylinder 13 is fixed to the bottom of the hollow shaft 11. The hollow shaft 11 serves as a liquid conveying channel, receiving liquid from the storage tank 1 through the top liquid inlet 12, and guiding the liquid into the centrifugal cylinder 13 using the hollow structure, achieving precise flow guidance before centrifugal filtration. The drive motor 10 provides rotational power to the hollow shaft 11, driving the centrifugal cylinder 13 to rotate at high speed, using centrifugal force to accelerate the separation of suspended matter in the liquid and improve the primary filtration efficiency.

[0026] The centrifuge cylinder 13 has a first filter membrane 14 installed on its inner wall. The centrifuge cylinder 13 generates a centrifugal force field through rotation, causing large particles of impurities in the liquor, such as lees and protein aggregates, to quickly settle to the cylinder wall. This, combined with the first filter membrane 14, achieves efficient solid-liquid separation. The first filter membrane 14 intercepts micron-sized impurities in the liquor through its microporous structure. At the same time, its high-temperature resistance and corrosion resistance properties adapt to the acidic and alkaline environment of baijiu, ensuring filtration stability and the preservation of flavor substances in the liquor.

[0027] A support plate 15 is fixed to the inner wall of the lower half of the aging tank 8. A filter cylinder 16 is located in the center of the support plate 15. A second filter membrane 17 is installed on the inner wall of the filter cylinder 16. An inlet hole 12 is opened on the outer wall of the top of the hollow shaft 11. A feed valve is provided on one side of the top shell 9. The support plate 15 serves as a supporting structure for the filter cylinder 16, ensuring the stable installation of the secondary filtration unit. The filter cylinder 16, as a secondary filtration container, works in conjunction with the second filter membrane 17 to further remove residual fine particles and improve the clarity of the wine.

[0028] It also includes a wine storage tank 1, with an output pipe 7 at the bottom of one side. One end of the output pipe 7 is connected to the feed valve on one side of the top shell 9, and an output pump 6 is installed on the output pipe 7. The wine storage tank 1 serves as a wine storage container, and the bottom output pipe 7, in conjunction with the output pump 6, can discharge the wine from the wine storage tank 1.

[0029] The bottom of one side of the aging tank 8 is equipped with a discharge valve, and one end of the discharge valve is equipped with a return pipe 4. A return pump 5 is installed on the return pipe 4, and one end of the return pipe 4 is connected to the inside of the storage tank 1. The discharge valve and the return pipe 4 form a wine return channel. The switching between filtration and return circulation is controlled by a solenoid valve. The single circulation cycle can be controlled within 10-15 minutes to ensure that the wine is fully processed.

[0030] One end of the output shaft of the drive motor 10 is fixed to the top end of the hollow shaft 11. This ensures that the hollow shaft 11 rotates stably.

[0031] The top side of the aging tank 8 is equipped with a feeding valve 2 and a temperature sensor 3. The temperature sensor 3's probe can extend to the bottom area of ​​the aging tank 8. The top of the storage tank 1 is also equipped with a feeding valve 2 and a temperature sensor 3. The feeding valve 2 allows for the addition of flavoring wine or aged wine during the aging process to achieve fine-tuning of the flavor; the temperature sensor 3 monitors the temperature of the wine in real time, providing parameter basis for ultrasonic aging.

[0032] An ultrasonic transducer 18 is installed at the center of the bottom of the aging tank 8. The ultrasonic transducer 18 generates microjets through cavitation effect, which breaks down large molecular aggregates in the wine, thereby increasing the esterification reaction rate and shortening the aging cycle.

[0033] The first filter membrane 14 is a ceramic filter membrane, and the second filter membrane 17 is a polytetrafluoroethylene (PTFE) filter membrane. The second filter membrane 17, a PTFE membrane, uses superhydrophobic properties to reduce the adsorption loss of the wine, and its pore size can intercept microorganisms and colloidal substances while allowing flavor components to pass through, thus achieving filtration without diminishing the aroma.

[0034] Both the centrifuge cylinder 13 and the filter cylinder 16 have mesh openings on their side walls to allow the wine to pass through.

[0035] During the aging process of baijiu, the liquor in the storage tank 1 is sent to the top shell 9 through the output pipe 7 via the output pump 6. After entering the hollow shaft 11 through the liquid inlet 12 at the top of the hollow shaft 11, the liquor enters the centrifugal cylinder 13. The drive motor 10 drives the hollow shaft 11 to rotate, and the liquor in the centrifugal cylinder 13 is centrifuged and filtered. The liquor after the first filtration enters the support plate 15 and enters the filter cylinder 16 by gravity. It undergoes a second gravity filtration through the second filter membrane 17 to filter impurities in the liquor. Through the second filtration, turbidity is removed, off-flavors are removed, and aging is accelerated. The filtered liquor returns to the storage tank 1 through the return pipe 4 and the return pump 5. The filtration process can be repeated several times.

[0036] In addition, during the filtration process, high-frequency ultrasonic waves can be generated by the ultrasonic transducer 18 to produce microbubbles in the wine and break them rapidly to form shock waves. This causes large molecules such as proteins and fats to decompose into smaller molecules, accelerates the generation and balance of aroma substances such as esters and alcohols, and makes the wine more mellow.

[0037] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
