Description

Technical Field

[0001] This utility model relates to the field of winemaking technology, and more specifically, to an oxygen supply device that can precisely adjust the oxygen permeation rate. Background Technology

[0002] During fermentation and aging, wine requires adequate oxygen to promote micro-oxidation reactions of aroma compounds and phenolic substances, thereby enhancing its sensory quality. Generally, gas is injected into the fermentation tank via an oxygen supply device. This method relies on the oxygen permeability rate to control the total oxygen supply. However, in practical applications, it is difficult to precisely adjust the oxygen permeability rate, and flow rate regulation is often affected by factors such as pressure fluctuations and gas flow rate fluctuations, leading to uneven oxygen supply and limiting the application of micro-oxidation in winemaking. Micro-oxidation techniques in winemaking are mainly divided into two types: passive micro-oxidation, such as in oak barrels and tungsten barrels, which passively introduces oxygen based on the oxygen permeability of natural or synthetic materials. This technique relies on the natural permeation of the container itself, making precise control of the oxygen amount difficult and requiring a long aging time. Active micro-oxidation, on the other hand, involves artificially adding oxygen through elements made of oxygen-permeable materials. This allows for precise control of the amount and rate of oxygen addition, achieving the effects of traditional long-term aging in a shorter time. However, this technology requires complex equipment and a precise control system, and its operation demands specialized skills.

[0003] Precise oxygen supply rate and total oxygen volume are crucial for the micro-oxidation effect of wine, which requires the use of active micro-oxidation technology, that is, artificially adding oxygen through oxygen supply devices with different oxygen permeability rates.

[0004] Currently, some wineries in China rely on micro-oxygenators to introduce oxygen in actual micro-oxidation production. These devices are single-unit and can only be connected to one fermentation tank. Moreover, they are very expensive and cannot be used on a large scale in actual wine production.

[0005] In passive micro-oxidation, most wineries currently use oak barrels for wine micro-oxidation. However, oak barrels are expensive, have long aging periods, and limited uses, so they are generally only used for high-quality wines, while some mid- to low-end products have no chance of being processed in oak barrels. More importantly, gas diffusion in traditional oak barrels exhibits strong heterogeneity; almost no oak barrel has a completely uniform oxygen permeability rate. Besides these, other passive micro-oxidation technologies such as ferrule barrels, earthenware jars, and cement tanks are also used for wine micro-oxidation. Ferro barrels have high maintenance costs and their sealing elements are prone to aging, while earthenware and cement jars are limited by firing processes and clay formulations, making the actual oxygen permeability rate and total oxygen flow uncontrollable. Among active micro-oxidation technologies, micro-oxygenators are the best choice. They introduce very small amounts of oxygen into grape juice or wine through a specially designed electronic control system and gas flow regulation device, exhibiting precise sensitivity in oxygen permeability rate and flow regulation. However, such high-precision micro-oxygenation equipment has high purchase and maintenance costs, making it unavailable for many small and medium-sized wineries. Utility Model Content

[0035] The principles and features of this utility model are described below. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0036] like Figure 1 As shown, the oxygen supply device of this utility model with adjustable oxygen permeation rate includes an oxygen cylinder 1 and an oxygen main pipe 3 connected to the outlet of the oxygen cylinder 1, and also includes at least one oxygen branch pipe 31; one end of the oxygen branch pipe 31 is connected to the oxygen main pipe 3, and the other end is equipped with an oxygen aerator head 11, which can input oxygen into the fermenter; the oxygen branch pipe 31 is equipped with a precision pressure reducing valve 6 and a gas flow quality controller 7.

[0037] The oxygen supply device of this invention, which can precisely adjust the oxygen permeation rate, has at least one oxygen branch pipe 31 on the main oxygen pipe 3, so that the oxygen supply of each oxygen branch pipe 31 can be independently controlled; the precision pressure reducing valve 6 and the gas flow quality controller 7 can jointly adjust the gas pressure and gas flow rate in the oxygen branch pipe 31, and through the oxygen aerator 11, realize the micro-oxidation operation of the wine in the fermentation tank, thereby achieving adjustable and controllable oxygen permeation rate.

[0038] This invention relates to an oxygen supply device with a precisely adjustable oxygen permeation rate. In the micro-oxidation process of winemaking, the oxygen permeation rate can be flexibly adjusted according to the actual needs of different stages of the winemaking process, ensuring the precision and stability of the oxygen supply. It eliminates the need for expensive and uncontrollable oak barrels, and the device has a simple structure, low cost, and high flexibility.

[0039] The precision pressure reducing valve 6 is a gas pressure regulating valve that enables precise pressure adjustment and is commonly used for precise control of gas cylinder or branch pressure. The oxygen aerator head 11 is a device used for micro-oxidation during the fermentation or aging of wine. It increases the dissolved oxygen content in the wine by slowly and evenly injecting oxygen, thereby achieving micro-oxidation during fermentation or aging. The gas mass flow controller 7 is an instrument used to control the mass of gas passing through a pipeline per unit time. This mass flow controller measures the mass flow rate of the gas, not its volumetric flow rate. It calculates the mass flow rate based on parameters such as gas density change, pressure, and temperature, and is commonly used in industrial process control requiring high precision.

[0040] Preferably, the precision pressure reducing valve 6 is located near one end of the oxygen branch pipeline 31, and the gas flow quality controller 7 is located near the other end of the oxygen branch pipeline 31. When transporting oxygen, the oxygen is first depressurized by the precision pressure reducing valve 6, and then the gas flow rate is controlled by the gas flow quality controller 7, so that the oxygen flow rate and velocity entering the fermenter can be better controlled, and good micro-oxidation can be achieved.

[0041] Preferably, a pressure reducing valve 2 is provided between the outlet of the oxygen cylinder 1 and the main oxygen pipeline 3; the pressure reducing valve 2 can divide the oxygen pressure output by the oxygen cylinder 1, thereby ensuring good stability of oxygen supply to each fermenter.

[0042] Preferably, the range of the precision pressure reducing valve 6 is 0-0.2MPa. This range of precision pressure reducing valve 6 can control the gas pressure of the oxygen branch pipeline 31 within a small pressure range, effectively buffering the large gas pressure in the main oxygen pipeline 3, and avoiding the instability of the gas flow quality controller due to excessive pressure difference between the front and rear.

[0043] Preferably, the pressure reducing valve 2 has a range of 0-2.5MPa, which provides better pressure distribution.

[0044] Preferably, one end of the oxygen branch pipe 31 is connected to the oxygen main pipe 3 via a tee connector 4; the tee connector 4 can ensure that the gas in the oxygen main pipe 3 flows stably to the oxygen branch pipe 31.

[0045] Preferably, an air pipe valve 5 is installed on the oxygen branch pipeline 31, and the air pipe valve 5 is close to the air pipe tee connector 4; the oxygen branch pipeline 31 can be independently and flexibly controlled through the air pipe valve 5.

[0046] Preferably, the oxygen aerator 11 is connected to the other end of the oxygen branch pipe 31 via a stainless steel pipe 10. The stainless steel pipe 10 and the oxygen aerator 11 are used to insert into the fermentation tank, so that the oxygen branch pipe 31 can supply oxygen to the wine in the fermentation tank.

[0047] In a further preferred embodiment, in order to ensure that the oxygen can fully contact the wine, the oxygen supply pipe should be inserted into the wine so that the output oxygen can directly contact the wine. The present invention installs a stainless steel pipe 10 on the oxygen branch pipe 31, which can prevent other pipe materials from contaminating the wine after entering the wine. At the same time, the stainless steel pipe 10 has a long service life and stable physical and chemical properties, which effectively improves the stability of the device.

[0048] Preferably, this embodiment also includes a dissolved oxygen monitoring system, which includes at least one oxygen sensor patch 9, which can be installed inside the fermentation tank. The oxygen sensor patch 9 can monitor the dissolved oxygen in the tank in real time during the micro-oxidation process, so as to adjust the oxygen dosage and duration required for micro-oxidation at different brewing stages as needed.

[0049] Specifically, in order to ensure the accuracy and comprehensiveness of real-time dissolved oxygen monitoring, multiple oxygen sensor patches 9 can generally be installed in a fermentation tank. Furthermore, the multiple oxygen sensor patches 9 should be located at different heights within the fermentation tank, so that the dissolved oxygen level in the wine can be comprehensively detected, thereby effectively improving the micro-oxidation effect.

[0050] Preferably, the dissolved oxygen monitoring system is also connected to the control unit. The oxygen cylinder 1 is also equipped with a device that can be automatically opened and closed. This device is connected to the control unit. At the same time, the control unit can also be connected to devices such as the precision pressure reducing valve 6 and the gas flow quality controller 7. In this way, the control unit can realize the automatic control of oxygen delivery and effectively realize the automation of micro-oxidation of wine.

[0051] Preferably, there are multiple oxygen branch pipes 31, with each oxygen branch pipe 31 corresponding to a fermenter; in this way, the gas transmission pipes between the tanks are independently controlled, ensuring the independence of the micro-oxidation operation of each fermenter and meeting the process and production requirements of different oxygen permeation rates.

[0052] Preferably, the fermentation tank is a stainless steel tank 8; using a stainless steel tank 8 as the fermentation tank has the advantages of low cost and high stability.

The stainless steel pipe 10 and the oxygen aerator head 11 are located inside the stainless steel tank 8, with the oxygen aerator head 11 near the bottom of the stainless steel tank 8. Two oxygen sensor patches 9 are installed inside the stainless steel tank 8, one near the bottom and the other near the top.

[0056] The working process of the oxygen supply device of this utility model is as follows:

[0057] Oxygen flows out from oxygen cylinder 1, is pressure-reduced by pressure reducing valve 2, and is then allowed to flow through main oxygen pipeline 3 to each branch oxygen pipeline 31 by opening gas pipe valve 5.

[0058] Oxygen passes through a precision pressure reducing valve 6 and a gas flow quality controller 7 in the oxygen branch pipeline 31 to achieve pressure buffering and flow control. Then, it enters the wine in the stainless steel tank 8 through the stainless steel pipe 10 and the oxygen aerator 11, realizing a continuous, stable, and precise supply of micro-flow oxygen to ensure the micro-oxidation effect of the wine.

[0059] The oxygen sensor patch 9 monitors the dissolved oxygen in the stainless steel tank 8 in real time during the micro-oxidation process. Based on the monitoring results, the dissolved oxygen monitoring system can adjust the oxygen dosage and duration required for micro-oxidation at different brewing stages at any time.
