Description

Technical Field

[0001] This utility model relates to the technical field of wine production equipment, specifically to a carbon dioxide aeration device for the wine fermentation process. Background Technology

[0002] Wine, a beverage with a long history and rich cultural heritage, holds a significant place in both social occasions and daily life. In recent years, with increasing health awareness, the concept of healthy drinking has gradually gained popularity, becoming a new trend in wine consumption. In conventional wines, SO2, as the most important additive, plays a dual role in inhibiting bacteria and preventing oxidation during the winemaking process to ensure product quality. Some consumers exhibit high sensitivity and aversion to additives in food, believing that their presence is directly related to the health attributes of the product, thus influencing their purchasing decisions. Excessive addition of sulfur dioxide can also have side effects on the wine itself. More importantly, some people are allergic to sulfur dioxide, a common ingredient in wine, which further limits their consumption choices of conventional wines.

[0003] Therefore, in the production of sulfur-free wines, equipment and processes such as raw material control, high-pressure sterilization, pressurized fermentation, and closed operation replace the sterilization, anti-oxidation, and microbial contamination functions of SO2. Furthermore, high-density carbon dioxide maceration is used throughout the fermentation tank to achieve sulfur-free, closed, pressurized fermentation. Traditional fermentation tanks connect to a carbon dioxide cylinder via a gas pipe, with the carbon dioxide injection controlled by valve opening and closing. Because carbon dioxide is denser than air, the filling port is typically located at the bottom to ensure filling effectiveness and efficiency. Moreover, the gas pipe size cannot be too large due to equipment requirements, resulting in slow filling efficiency and long processing time, thus affecting production efficiency. Increasing the number of gas outlets in the gas pipe can lead to blockages during wine production, which is quite troublesome. Utility Model Content

[0004] In view of the technical problems existing in the prior art, the present invention provides a carbon dioxide aeration device for wine fermentation, which can effectively solve the technical problems existing in the prior art.

[0005] The technical solution of this utility model is:

[0006] A carbon dioxide aeration device for wine fermentation, comprising:

[0007] The fermentation tank has an internal interlayer, and the interlayer wall is evenly distributed with a number of ventilation holes that connect the fermentation tank and the interlayer.

[0008] The opening and closing mechanism includes a closing plug that is movably installed at the vent hole via a corresponding reset elastic element; during inflation, the gas pushes the closing plug outward so that the interlayer communicates with the fermentation tank body, and the reset elastic element is stretched.

[0009] The reversing mechanism includes a straight pipe that connects the jacket to an external air source via a corresponding three-way valve, with the other end of the straight pipe not connected to the three-way valve located inside the fermenter.

[0010] When the three-way valve is closed in the direction of connecting the jacket, the flow guiding mechanism is used to guide the gas in the jacket into the fermenter body, so that the jacket is in a negative pressure state, and the closing plug closes the vent hole under the action of negative pressure adsorption force.

[0011] The flow guiding mechanism includes a Venturi tube connecting the three-way valve and an external gas source. The Venturi tube is connected to the interlayer through a corresponding bypass pipe and bypass valve. When the three-way valve is closed in the direction connecting the interlayer, the bypass valve is opened, and the gas in the interlayer is guided through the Venturi tube into the fermenter body under negative pressure.

[0012] The top of the fermentation tank is connected to a corresponding guide pipe, and a corresponding carbon dioxide detector and a pressure gauge are respectively installed on the guide pipe. The fermentation tank is also connected to an air inlet valve and an air inlet pipe that are connected in parallel with the carbon dioxide detector and in series with the pressure gauge.

[0013] The vent hole is wider at the outside and narrower at the inside. The closing plug is a frustum shape that matches the shape of the vent hole, and a rubber layer is fixedly installed around its inclined periphery by adhesive. The closing plug is installed at the vent hole by interference fit through the rubber layer.

[0014] The inner wall of the fermentation tank is laterally fixed with a corresponding limiting rod at the position opposite to the vent hole. The reset elastic element is sleeved on the outside of the limiting rod and its two ends are respectively fixed to the closing plug and the inner wall of the fermentation tank.

[0015] The external gas source is a carbon dioxide cylinder, and the outlet of the carbon dioxide cylinder is equipped with a corresponding gas valve.

[0016] Advantages of this utility model:

[0017] 1) This utility model provides a corresponding interlayer on the inner side wall of the fermenter and distributes corresponding air vents evenly on the interlayer wall, so that the gas flows from the periphery to the center and pushes the oxygen outward from the bottom, so as to uniformly and quickly fill the fermenter with external gas through the interlayer, better exhaust the internal oxygen, and thus improve the efficiency of carbon dioxide filling.

[0018] 2) However, when grape juice is added later, it is easy to fill the interlayer through the vent hole. Therefore, this utility model further improves the invention by movably installing a corresponding closing plug at the vent hole through a corresponding reset elastic element. When the gas is inflated, the gas pushes the closing plug outward to connect the interlayer with the fermentation tank. When the inflation is completed, the stretched reset elastic element drives the closing plug to reset and seal the vent hole under the action of elastic potential energy, ensuring that the interlayer and the fermentation tank are not connected during subsequent fermentation. Furthermore, the vent hole is set to be wider on the outside and narrower on the inside, and the closing plug is set to be a frustum shape that matches the shape of the vent hole. A rubber layer is fixedly installed around the bevel of the closing plug by an adhesive method. When the closing plug is reset, its shape and the rubber layer will cause the closing plug to press against the vent hole to ensure a sealing effect.

[0019] 3) This utility model has a corresponding guide pipe connected to the top of the fermentation tank, and a corresponding carbon dioxide detector and pressure gauge are respectively installed on the guide pipe. When the carbon dioxide concentration detected by the carbon dioxide detector reaches 100%, the closed valve connected in series with the carbon dioxide detector is closed, and the three-way valve is adjusted so that the jacket is not connected to the external gas source and the bypass valve is opened, and the jacket is connected to the Venturi tube. Carbon dioxide is continued to be charged into the fermentation tank through the straight pipe until the value of the pressure gauge reaches the set value and the charging stops. When the charging continues, the gas in the jacket is extracted by the negative pressure of the Venturi tube and guided by the straight pipe. After the gas in the jacket is extracted, it is in a negative pressure state, which causes the closing plug to be tightly closed under the action of negative pressure adsorption force, further improving the closing effect of the opening and closing mechanism on the vent.

[0020] 4) The present invention provides a corresponding limiting rod on the fermentation tank body in the interlayer, and a reset elastic element is sleeved on the outside of the limiting element, so that the reset elastic element can extend and retract axially along the limiting element, so that the closing plug can move horizontally axially, thereby ensuring the practical effect of the present invention.

[0025] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0026] refer to Figure 1-3 A carbon dioxide aeration device for wine fermentation, comprising:

[0027] Fermentation tank 1, which has a corresponding interlayer 2 inside, and the interlayer wall is evenly distributed with a number of ventilation holes 201 connecting the fermentation tank 1 and the interlayer 2.

[0028] The opening and closing mechanism 3 includes a closing plug 302 that is movably installed at the vent 201 via a corresponding reset elastic element 301; when inflating, the gas pushes the closing plug 302 outward so that the interlayer 2 is connected to the fermentation tank 1, and the reset elastic element 301 is stretched.

[0029] The reversing mechanism 4 includes a straight pipe 402 that connects the jacket 2 and the external air source through a corresponding three-way valve 401. The other end of the straight pipe 402 that is not connected to the three-way valve 401 is located inside the fermentation tank 1.

[0030] When the three-way valve 401 is closed in the direction of connecting the jacket 2, the flow guiding mechanism 5 is used to guide the gas in the jacket 2 into the fermentation tank 1, so that the jacket 2 is in a negative pressure state, and the closing plug 302 closes the vent hole 201 under the action of negative pressure adsorption force.

[0031] This invention provides a corresponding interlayer 2 on the inner wall of the fermentation tank 1, and evenly distributes corresponding vent holes 201 on the wall of the interlayer 2. This allows gas to flow from the periphery to the center and then push oxygen outward from the bottom. This allows external gas sources to be evenly and quickly introduced into the fermentation tank 1 through the interlayer 2, thus better releasing internal oxygen and improving the efficiency of carbon dioxide filling.

[0032] The flow guiding mechanism 5 includes a Venturi tube 501 connecting the three-way valve 401 and the external gas source. The Venturi tube 501 is connected to the interlayer 2 through a corresponding bypass pipe 502 and bypass valve 503. When the three-way valve 401 is closed in the direction connecting the interlayer 2, the bypass valve 503 is opened, and the gas in the interlayer 2 is guided into the fermentation tank 1 under negative pressure through the Venturi tube 501.

[0033] The top of the fermentation tank 1 is connected to a corresponding guide pipe 6, and a corresponding carbon dioxide detector 7 and pressure gauge 8 are respectively installed on the guide pipe 6. The fermentation tank 1 is also connected to an air inlet valve 9 and an air inlet pipe 10 that are connected in parallel with the carbon dioxide detector 7 and in series with the pressure gauge 8.

[0034] This invention features a connecting pipe 6 at the top of the fermentation tank 1, with a carbon dioxide detector 7 and a pressure gauge 8 installed on the pipe 6. When the carbon dioxide concentration detected by the carbon dioxide detector 7 reaches 100%, the closed valve connected in series with the carbon dioxide detector 7 is closed, and the three-way valve 401 is adjusted so that the jacket 2 is not connected to the external gas source and the bypass valve 503 is opened, connecting the jacket 2 to the Venturi tube 501. Carbon dioxide is continuously injected into the fermentation tank 1 through the straight pipe 402 until the pressure gauge 8 reaches the set value of 0.2 MPa, at which point the inflation stops. During continued inflation, the gas in the jacket 2 is drawn out by the negative pressure of the Venturi tube 501 and guided by the straight pipe 402. After the gas in the jacket 2 is drawn out, it is under negative pressure, which causes the closing plug 302 to tightly seal the vent hole 201 under the action of negative pressure adsorption, further improving the closing effect of the opening and closing mechanism 3 on the vent hole 201.

[0035] The vent 201 is wider on the outside and narrower on the inside. The closing plug 302 is a frustum shape that matches the shape of the vent 201. A rubber layer 11 is fixedly installed around its inclined periphery by adhesive. The closing plug 302 is installed at the vent 201 by interference fit through the rubber layer 11.

[0036] However, when grape juice is added later, it can easily fill the interlayer 2 through the vent 201. Therefore, this invention further incorporates a corresponding closing plug 302 that can be movably installed at the vent 201 via a corresponding resetting elastic element 301. During inflation, the gas pushes the closing plug 302 outward, connecting the interlayer 2 with the fermentation tank 1. When inflation is complete, the stretched resetting elastic element 301, under the action of elastic potential energy, drives the closing plug 302 to reset and seal the vent 201, ensuring that the interlayer 2 does not connect with the fermentation tank 1 during subsequent fermentation. The vent 201 is set to be wider on the outside and narrower on the inside, and the closing plug 302 is set to be a frustum shape that matches the shape of the vent 201. A rubber layer 11 is fixedly installed around the bevel of the closing plug 302 by adhesive bonding. When the closing plug 302 is reset, its shape and the rubber layer 11 will make the closing plug 302 pressurize the vent 201 to ensure the sealing effect. Furthermore, without affecting the subsequent production of the fermentation tank, the aeration efficiency can be further improved by increasing the diameter of the pipe between the Venturi tube and the external gas source.

[0037] The inner wall of the fermentation tank 1 is laterally fixed with a corresponding limiting rod 12 at the position opposite to the vent 201. The reset elastic element 301 is sleeved on the outside of the limiting rod 12 and its two ends are respectively fixed to the closing plug 302 and the inner wall of the fermentation tank 1.

[0038] In this invention, a corresponding limiting rod 12 is provided on the fermentation tank 1 inside the interlayer 2, and a reset elastic member 301 is sleeved on the outside of the limiting member, so that the reset elastic member 301 can extend and retract axially along the limiting member, and the closing plug 302 can move horizontally axially, so as to ensure the practical effect of this invention.

[0039] The external gas source is a carbon dioxide cylinder 13, and a corresponding gas outlet valve 14 is provided at the outlet of the carbon dioxide cylinder 13.

[0040] It should be noted that this embodiment is implemented in the same way as the first embodiment in terms of principle and technical effect. For the sake of brevity, any parts not mentioned in this embodiment can be referred to the corresponding content in the first embodiment.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
