Description

Technical Field

[0001] The utility model relates to the field of wine brewing, and in particular to a wine storage tank and a stirring device. Background Art

[0002] In winemaking, certain specialty wine varieties, with their complex production processes and unique flavor profiles, have become treasures that winemakers constantly explore. One particularly challenging aspect of this process is the need to add specialized ingredients for a secondary fermentation after the primary fermentation, placing extremely high demands on storage conditions. Traditional wine storage tanks are often unable to cope with such delicate operations, revealing their limitations. However, it is precisely against this backdrop that a wave of innovation in wine storage tanks has quietly begun, dedicated to addressing the storage challenges faced by specialty wines. Utility Model Content

[0003] In view of this, the present invention provides a wine storage tank and stirring device that can meet the secondary fermentation process requirements of special wine varieties. After the fermentation material is initially placed in the tank body, a first sealing cover is sealed and connected to the tank body to achieve sealing and carry out the primary fermentation. After a period of primary fermentation, the secondary fermentation material is placed into the tank body by puncturing the blind groove on the first sealing cover, and then the second sealing cover is sealed and connected to the tank body to achieve sealing and carry out the secondary fermentation, thereby achieving the secondary fermentation of special wine varieties.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A wine storage tank comprises a tank body, a first sealing cover and a second sealing cover sealedly connected to the top of the tank body, wherein the top of the tank body is open, the edge of the first sealing cover is sealedly connected to the open inner wall of the tank body, the first sealing cover is provided with a blind groove, the edge of the second sealing cover is sealedly connected to the open inner wall of the tank body, and the second sealing cover is located above the first sealing cover.

[0006] The open top of the tank creates a primary seal through the tight fit of the first sealing cover against the inner wall. A second sealing cover then covers the first, creating a double seal. This design effectively isolates the wine from outside air, moisture, and odors, minimizing the risk of oxidation and ensuring the wine retains its original aroma and taste for a long time.

[0007] The blind groove on the primary sealing cap is more than just a decorative element; it performs a crucial function—regulating internal pressure. When temperature fluctuations within the tank cause the gas to expand or contract, the blind groove acts as a microchannel, allowing trace amounts of gas to circulate, automatically adjusting the internal pressure to a safe level. This prevents seal failure caused by pressure imbalance and ensures a dynamic balance between the internal and external environments. Through the coordinated operation of the primary and secondary sealing caps, and the ingenious design of the blind groove, this wine storage tank achieves a perfect balance between extreme sealing and moderate breathability. This ensures that the wine is protected from adverse external influences while allowing it to undergo subtle maturation changes under appropriate conditions, promoting the gradual development of complex flavors.

[0008] Furthermore, due to the unique processing techniques used to make special wine varieties, a secondary fermentation requires the addition of fermentable material after the initial fermentation. Traditional wine storage tanks are unable to meet these process requirements, but this wine storage tank, with its blind groove, can. Specifically, after the fermentable material is initially placed in the tank, the first sealing cap is hermetically connected to the tank body, achieving a seal and allowing for the initial fermentation. After a period of initial fermentation, the secondary fermentable material is placed into the tank body by puncturing the blind groove on the first sealing cap, and the second sealing cap is hermetically connected to the tank body, achieving a seal and allowing for the initial fermentation. This allows for the secondary fermentation of special wine varieties.

[0009] Preferably, the blind groove is in the shape of a circular ring.

[0010] Compared to straight lines or other shapes, the circular blind groove design allows for a more even distribution of pressure around the primary sealing cap. This means that pressure fluctuations from any direction can be quickly responded to and regulated. It also makes it easier to puncture the blind groove on the primary sealing cap and place the secondary fermentation product into the tank.

[0011] Preferably, the blind groove is provided on the lower surface of the first sealing cover.

[0012] The blind groove is close to the inside of the tank, so it can sense changes in the environment inside the tank more directly and respond in time.

[0013] Preferably, the blind groove is provided on the upper surface of the first sealing cover.

[0014] Being arranged on the upper surface, it is easier for workers to find the position of the blind groove, so as to facilitate puncturing the blind groove on the first sealing cover and placing the secondary fermented material into the tank body.

[0015] Preferably, the blind groove is provided in the central area of ​​the first sealing cover.

[0016] Designing the blind groove in the center of the first sealing cap more accurately captures subtle pressure changes within the tank and responds quickly. This central design reduces the blind groove's direct impact on the peripheral sealing ring, thus preventing the blind groove from weakening the peripheral seal and further strengthening the tank's overall sealing performance.

[0017] Preferably, there is a gap between the upper surface of the first sealing cover and the lower surface of the second sealing cover.

[0018] A gap is left between the upper surface of the first sealing cap and the lower surface of the second sealing cap, creating a micro-buffer zone. This design allows for fine-tuned inflow and outflow of gas inside the tank through the central blind groove when necessary, while simultaneously preventing a significant influx of outside air. This creates a "gentle breathing" effect, effectively extending the wine's freshness and development of complexity.

[0019] Preferably, the upper surface of the second sealing cover is flush with the top of the side wall of the tank body.

[0020] The upper surface of the second sealing cover is designed to be completely flush with the top of the tank side wall, which not only gives the tank a smooth and harmonious appearance, but also eliminates any abrupt edges, reduces the possibility of dust accumulation, and improves overall hygiene standards.

[0021] Preferably, the thickness of the second sealing cover is greater than the thickness of the first sealing cover.

[0022] Compared with the first sealing cover, the second sealing cover is made of a material with a greater thickness, which not only enhances its structural strength and ensures its stability in the face of external collisions, but also greatly improves its service life. It can maintain good sealing performance even under frequent use.

[0023] A stirring device for a wine storage tank comprises a base, a turntable arranged on the base, a stirring rack arranged on the turntable, and a plurality of wine storage tanks as described above arranged on the stirring rack.

[0024] The turntable on the base rotates, driving the stirring rack and wine storage tank above it to rotate regularly. This gentle and continuous stirring mode helps to promote the uniform mixing of the wine's internal components, accelerate the aging process, while avoiding the damage that may be caused by violent shaking, ensuring that the delicate texture of each bottle of wine is fully preserved.

[0025] Preferably, the stirring rack is provided with a plurality of fixed positions, the wine storage tank is placed in the fixed positions, and the side walls of the fixed positions are provided with a plurality of soft rubbers.

[0026] The stirring rack is equipped with multiple fixed slots specially designed for wine storage tanks. The side walls of each slot are embedded with multi-point soft rubber supports, which can not only hold the storage tank steadily, but also gently fit the curve of the tank body, effectively reducing vibration and friction during movement, and maximizing the protection of the stability and safety of the wine in the tank.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] This new wine storage tank features an open top design. A first sealing cover securely fits against the inner wall of the tank, creating a preliminary seal. Furthermore, a second sealing cover overlays the first, creating a double-layer seal. This design effectively isolates the wine from outside air, moisture, and odors, minimizing the risk of oxidation and ensuring the wine retains its original aroma and taste over time.

[0029] The blind groove on the primary sealing cap is more than just a decorative element; it performs a crucial function—regulating internal pressure. When temperature fluctuations within the tank cause the gas to expand or contract, the blind groove acts as a microchannel, allowing trace amounts of gas to circulate, automatically adjusting the internal pressure to a safe level. This prevents seal failure caused by pressure imbalance and ensures a dynamic balance between the internal and external environments. Through the coordinated operation of the primary and secondary sealing caps, and the ingenious design of the blind groove, this wine storage tank achieves a perfect balance between extreme sealing and moderate breathability. This ensures that the wine is protected from adverse external influences while allowing it to undergo subtle maturation changes under appropriate conditions, promoting the gradual development of complex flavors.

[0030] Furthermore, due to the unique processing techniques used to make special wine varieties, a secondary fermentation requires the addition of fermentable material after the initial fermentation. Traditional wine storage tanks are unable to meet these process requirements, but this wine storage tank, with its blind groove, can. Specifically, after the fermentable material is initially placed in the tank, the first sealing cap is hermetically connected to the tank body, achieving a seal and allowing for the initial fermentation. After a period of initial fermentation, the secondary fermentable material is placed into the tank body by puncturing the blind groove on the first sealing cap, and the second sealing cap is hermetically connected to the tank body, achieving a seal and allowing for the initial fermentation. This allows for the secondary fermentation of special wine varieties. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The technical solution in this application will be described below with reference to the accompanying drawings. Example 1

[0039] This embodiment provides a stirring device for a wine storage tank, including a base 100 , a turntable 200 disposed on the base 100 , a stirring rack 300 disposed on the turntable 200 , and a plurality of wine storage tanks 400 disposed on the stirring rack 300 .

[0040] The turntable 200 mounted on the base 100 rotates, driving the stirring frame 300 and wine storage tank 400 mounted thereon to rotate regularly. This gentle and continuous stirring mode helps promote uniform mixing of the wine's internal components, accelerates the aging process, and avoids the damage that can be caused by violent shaking, ensuring that the delicate texture of each bottle of wine is fully preserved. The turntable 200 is existing technology and is commercially available. It is pluggable and powered, driving the stirring frame 300.

[0041] In this embodiment, a plurality of fixed positions 310 are provided in the stirring rack 300 , and the wine storage tank 400 is placed in the fixed positions 310 . The side walls of the fixed positions 310 are provided with a plurality of soft rubbers 311 .

[0042] The stirring rack 300 is provided with a plurality of fixed positions 310 specially designed for the wine storage tank 400. The side wall of each position is embedded with multi-point soft rubber 311 supports, which can not only hold the storage tank steadily but also gently fit the curve of the tank body, effectively reducing vibration and friction during movement, and maximizing the stability and safety of the wine in the tank.

[0043] The wine storage tank 400 includes a tank body 410, a first sealing cover 420 and a second sealing cover 430 sealedly connected to the top of the tank body 410. The top of the tank body 410 is open, and the edge of the first sealing cover 420 is sealedly connected to the open inner wall of the tank body 410. The first sealing cover 420 is provided with a blind groove 421. The edge of the second sealing cover 430 is sealedly connected to the open inner wall of the tank body 410, and the second sealing cover 430 is located above the first sealing cover 420.

[0044] The open top of the can 410 forms a preliminary seal through the tight fit of the first sealing cover 420 against the inner wall of the can 410. Furthermore, the second sealing cover 430 further covers the first sealing cover 420, creating a double-layer seal. This design effectively isolates the wine from outside air, moisture, and odors, minimizing the risk of oxidation and ensuring that the wine retains its original aroma and taste for a long time.

[0045] The blind groove 421 on the first sealing cover 420 is more than just a decorative feature; it performs a crucial function: regulating internal pressure. When temperature fluctuations within the tank cause the gas to expand or contract, the blind groove 421 acts as a microchannel, allowing trace amounts of gas to circulate, automatically adjusting the internal pressure to a safe level. This prevents seal failure caused by pressure imbalance and ensures a dynamic balance between the internal and external environments of the tank body 410. Through the coordinated operation of the first and second sealing covers 420 and 430, and the ingenious design of the blind groove 421, this wine storage tank 400 achieves a perfect balance between extreme sealing and moderate breathability. This ensures that the wine is protected from adverse external influences while allowing it to undergo subtle maturation changes under appropriate conditions, promoting the gradual development of complex flavors.

[0046] Furthermore, due to the unique processing techniques used for special wine varieties, secondary fermentation requires the addition of fermentable material after the initial fermentation. Conventional wine storage tanks 400 are unable to meet these process requirements. However, the present wine storage tank 400, due to the presence of blind grooves 421, can meet these process requirements. Specifically, after the fermentable material is initially placed in tank body 410, first sealing cap 420 is hermetically connected to tank body 410 to achieve a seal and proceed with the initial fermentation. After a period of initial fermentation, the secondary fermentable material is placed into tank body 410 by puncturing blind groove 421 on first sealing cap 420. Second sealing cap 430 is then hermetically connected to tank body 410 to achieve a seal and proceed with the initial fermentation, thereby achieving the initial fermentation of the special wine variety.

[0047] Figure 1 This is a structural diagram of the wine storage tank after secondary fermentation.

[0048] In this embodiment, the blind groove 421 is in the shape of a circular ring.

[0049] Compared to straight lines or other shapes, the circular blind groove 421 is more evenly distributed around the first sealing cover 420. This means that pressure fluctuations from any direction can be quickly responded to and adjusted. It also makes it easier to pierce the blind groove 421 on the first sealing cover 420 and place the secondary fermentation product into the tank body 410.

[0050] In this embodiment, the blind groove 421 is disposed on the lower surface of the first sealing cover 420 .

[0051] The blind groove 421 is adjacent to the interior of the tank body 410 and can more directly sense changes in the environment inside the tank and respond in a timely manner.

[0052] In this embodiment, the blind groove 421 is disposed in the central area of ​​the first sealing cover 420 .

[0053] Designing blind groove 421 in the center of first sealing cap 420 more accurately captures subtle pressure changes within the tank and responds quickly. This central design reduces the direct impact of blind groove 421 on the peripheral sealing ring, thus preventing any weakening of the peripheral seal due to blind groove 421 and further strengthening the overall sealing effect of tank body 410.

[0054] In this embodiment, there is a gap between the upper surface of the first sealing cover 420 and the lower surface of the second sealing cover 430 .

[0055] A gap is left between the upper surface of the first sealing cap 420 and the lower surface of the second sealing cap 430, creating a micro-buffer zone. This design allows for fine-tuned inflow and outflow of gas within the can via the central blind groove 421 when necessary, while simultaneously preventing a significant influx of outside air. This creates a "gentle breathing" effect, effectively extending the wine's freshness and the development of its complexity.

[0056] In this embodiment, the upper surface of the second sealing cover 430 is flush with the top of the side wall of the can body 410 .

[0057] The upper surface of the second sealing cover 430 is designed to be completely flush with the top of the side wall of the tank body 410, which not only gives the tank body 410 a smooth and harmonious appearance, but also eliminates any abrupt edges, reduces the possibility of dust accumulation, and improves the overall hygiene standard.

[0058] In this embodiment, the thickness of the second sealing cover 430 is greater than the thickness of the first sealing cover 420 .

[0059] Compared with the first sealing cover 420, the second sealing cover 430 is made of a material with a greater thickness, which not only enhances its structural strength and ensures its stability in the face of external collisions, but also greatly improves its service life and can maintain good sealing performance even under frequent use.

[0064] The wine storage tank 400 includes a tank body 410, a first sealing cover 420 and a second sealing cover 430 sealedly connected to the top of the tank body 410. The top of the tank body 410 is open, and the edge of the first sealing cover 420 is sealedly connected to the open inner wall of the tank body 410. The first sealing cover 420 is provided with a blind groove 421. The edge of the second sealing cover 430 is sealedly connected to the open inner wall of the tank body 410, and the second sealing cover 430 is located above the first sealing cover 420.

It also makes it easier to pierce the blind groove 421 on the first sealing cover 420 and place the secondary fermentation product into the tank body 410.
