Abstract
Description
Technical Field
[0001] This utility model relates to the field of winemaking technology, and more specifically, to a micro-oxidation tank for wine fermentation and aging. Background Technology
[0002] In wine production, adequate oxygen exposure promotes a series of chemical reactions during fermentation and aging, contributing to the softening of the wine's body, the stabilization of its color, and the enhancement of its aroma. Therefore, oxygen control is crucial in the fermentation and aging process of wine.
[0003] Traditional oxygen exposure methods often utilize oak barrels, typically achieved through the use of oak wood. The micropores of oak barrels allow oxygen to slowly permeate into the wine, enhancing its flavor and complexity. However, the oxygen permeation rate and actual oxygen flow in oak barrels are influenced by the natural characteristics of the wood, such as its origin and grain. Each barrel exhibits a different oxygen permeation rate and total oxygen flow, making it impossible to precisely control the micro-oxidation reactions that may occur during fermentation or aging. Furthermore, oak barrels also present challenges such as high cost and significant space requirements.
[0004] With the increasing popularity of stainless steel containers, stainless steel tanks have gradually begun to replace expensive oak barrels as the main fermentation and aging vessels. However, stainless steel tanks do not possess the micro-oxygenation properties of oak barrels and cannot provide the trace amounts of oxygen required for aging, which is detrimental to the fermentation and aging of high-quality dry red wines. This problem was solved with the advent of micro-oxygenation technology.
[0005] Wine micro-oxidation technology refers to the technique of continuously or intermittently introducing trace amounts of oxygen into wine under controlled conditions to promote its maturation and enhance its sensory quality. In recent years, micro-oxidation technology has been applied to the fermentation and aging processes of wine. By controlling the penetration of trace amounts of oxygen, it can effectively improve the quality of wine, promote its softening, and enhance its aroma.
[0006] However, existing micro-oxidation devices are complex in structure and cannot achieve monitoring and precise control of micro-oxidation, resulting in poor performance of micro-oxidation technology and making it difficult to promote. Utility Model Content

[0030] The attached diagram lists the components represented by each number as follows:
[0031] 1. Safety valve; 2. Oxygen pipeline; 3. Manhole; 4. Mounting rod; 5. Oxygen sensor; 6. Thermometer; 7. Sampling valve; 8. Oxygen aerator head; 9. Butterfly valve; 10. Tank body. Detailed Implementation
[0032] 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.
[0033] like Figure 1 As shown, the micro-oxidation tank of this utility model for wine fermentation and aging includes a tank body 10, an oxygen pipeline 2 inside the tank body 10, and an oxygen aerator head 8 installed at the outlet end of the oxygen pipeline 2; it also includes an oxygen monitoring device, which includes at least two oxygen sensors 5, which are respectively installed at different heights inside the tank body 10.
[0034] This invention relates to a micro-oxidation tank for wine fermentation and aging. An oxygen pipeline 2 is installed inside the tank body 10, and oxygen is supplied to the wine liquid in the tank body 10 through an oxygen aerator 8, enabling micro-oxygen fermentation and micro-oxygen aging of the wine. An oxygen sensor 5 is installed inside the tank body 10 to achieve real-time measurement of dissolved oxygen content at different locations within the tank body 10, allowing adjustments to the oxygen dosage and duration required for different stages of brewing. At least two oxygen sensors 5 are installed at different heights within the tank body 10, enabling real-time monitoring of dissolved oxygen at different locations within the tank body 10, resulting in more accurate and comprehensive monitoring results.
[0035] This invention relates to a micro-oxidation tank for wine fermentation and aging, which enables uniform and precise control of oxygen supply during the wine fermentation and aging process. It overcomes the problems of lack of target and poor controllability in dissolved oxygen control during traditional wine fermentation and aging processes, and achieves fine management of dissolved oxygen during the winemaking process.
[0036] Preferably, the oxygen aerator head 8 is made of stoneware material, which is a type of ceramic product between pottery and porcelain. When oxygen is aerated through the oxygen aerator head 8, it can ensure that the oxygen diffuses at a slow and uniform rate, avoiding the problem of oxygen accumulating in the headspace of the tank 10.
[0037] Preferably, the inlet of the oxygen pipeline 2 is connected to an oxygen supply device, which can be an oxygen cylinder.
[0038] Preferably, it also includes a mounting rod 4, which includes a fixed end and at least two mounting ends. The fixed end is fixedly connected to the top of the tank 10, and each mounting end is equipped with an oxygen sensor 5. By installing the oxygen sensor 5 through the mounting rod 4, the oxygen sensor 5 can be made more stable. In addition, the oxygen sensor 5 is not directly installed on the inner wall of the tank 10, but is located in the wine away from the inner wall. This makes the monitoring results of the oxygen sensor 5 more accurate and objective, thereby improving the control effect of micro-oxygen fermentation and micro-oxygen aging.
[0039] Preferably, the oxygen monitoring device further includes a signal receiving element, which is connected to the oxygen sensor 5 circuit and can receive the oxygen content signal from the oxygen sensor 5; thus, based on the oxygen content signal obtained by the signal receiving element, the oxygen supply process can be specifically adjusted.
[0040] Since the oxygen sensor 5 needs to be connected to the signal receiving element circuit, in a specific embodiment, the mounting rod 4 is a hollow rod body, and the wires of the oxygen sensor 5 are connected to the outside through the mounting rod 4.
[0041] Preferably, the tank 10 is a vertical cylindrical shape, and the oxygen aerator 8 is close to the bottom of the tank 10; the above structure can maximize the contact time between oxygen and grape juice or wine during the upward diffusion, which helps the oxygen to fully dissolve in the wine.
[0042] Preferably, the oxygen aerator head 8 is positioned vertically below the position of any oxygen sensor 5. Oxygen sensors 5 are placed at different heights within the tank (e.g., top, middle, and bottom) to monitor dissolved oxygen levels and observe its distribution. However, when an oxygen sensor 5 is at the same height as the oxygen aerator head 8, its proximity may cause it to detect higher levels of dissolved oxygen than the actual effect. Furthermore, oxygen sensors at the same height may also affect the oxygen output of the oxygen aerator head 8.
[0043] Preferably, the oxygen aerator 8 is positioned at one-third of the height of the tank 10 in the vertical direction; while not contacting the bottom of the tank 10, this position can maximize the contact time between the oxygen and the grape juice or wine during the upward diffusion, thereby improving the dissolved oxygen effect.
[0044] Preferably, the top of the tank 10 is provided with a manhole 3, and the bottom side wall is provided with a discharge port, on which a butterfly valve 9 is installed; the above structure facilitates the operation of the wine brewing process.
[0045] Preferably, the manhole 3 is equipped with a tank cover, and a safety valve 1 is installed on the tank cover. The safety valve 1 is a one-way valve that will actively release gas to the outside of the tank 10 when the gas (mainly CO2) inside the tank 10 reaches a certain pressure, without introducing gas into the tank 10. This is suitable for micro-oxidation during the wine fermentation stage. During the micro-oxidation stage of aging, the safety valve 1 can be removed and the outlet sealed to prevent oxygen from escaping from the tank.
[0046] Preferably, a thermometer 6 is also installed on the side wall inside the tank 10; used for temperature monitoring of wine during fermentation and aging, and also for temperature compensation when detecting dissolved oxygen content.
[0047] Preferably, the tank body 10 is also provided with a sampling port, and a sampling valve 7 is installed on the sampling port; through the sampling port and the sampling valve 7, the wine can be sampled and monitored during the micro-aerobic fermentation and aging process.
[0048] The micro-oxidation tank of this invention for wine fermentation and aging can be connected to a control element. The control element can acquire the monitoring results of the oxygen sensor 5 and control the specific oxygen supply process of the oxygen supply device to achieve automated control.
[0049] The present invention will be illustrated by specific embodiments below.
[0050] Example
[0051] In this embodiment, the oxygen pipeline 2 passes through the manhole 3 and is detachably mounted on the tank cover. The fixed end of the mounting rod 4 is fixed to the side wall of the manhole 3. The mounting rod 4 has two branches, each with an oxygen sensor 5 mounted at its end.
[0052] In this embodiment, both the oxygen pipeline 2 and the mounting rod 4 are far from the side wall of the tank 10 and are located close to the axis of the tank 10.
[0053] In this embodiment, the tank 10 has a capacity of 120L. Compared to traditional micro-oxidation technologies, which mostly rely on small-volume equipment of 10L or 20L such as oak barrels or laboratory equipment, the capacity of this tank 10 can be widely used in actual wine production.
[0054] The specific working process of this embodiment is as follows:
[0055] During the microaerobic fermentation or microaerobic aging process of wine, oxygen enters the wine liquid inside the tank 10 through oxygen pipeline 2. Oxygen sensor 5 monitors the dissolved oxygen content of the wine liquid in real time. Based on the monitoring results, when the dissolved oxygen level is too high, the oxygen input is reduced; when the dissolved oxygen level is too low, the oxygen input is increased.
[0056] Through the above process, the micro-oxidation process during micro-oxygen fermentation or micro-oxygen aging can be regulated and monitored.
