Description

Technical Field

[0001] This utility model relates to the field of fermentation tanks, and in particular to a plum wine fermentation tank. Background Technology

[0002] In the fermentation process of fruit wines such as plum wine, the fermentation tank is one of the core pieces of equipment, and its internal environment control directly affects fermentation efficiency and product quality. Traditional fermentation tanks typically use open vents or simple vent valves to release gas, but these methods have significant drawbacks in practical applications:

[0003] The open vents in existing technologies are prone to backflow of external air, which can disrupt the anaerobic environment inside the tank, leading to contamination by miscellaneous bacteria or oxidation reactions, thus affecting the flavor of the wine. Furthermore, the simple vent valves in existing technologies have insufficient pressure relief capacity and rely on manual adjustment, making it difficult to cope with the instantaneous generation of large amounts of gas during the peak fermentation period. This can easily cause a sudden increase in pressure inside the tank, posing a risk of tank explosion. Therefore, there is an urgent need for a device with a simple structure, requiring no external energy source, capable of unidirectional automatic venting and maintaining pressure balance inside the tank, in order to solve the technical bottlenecks in gas management of traditional fermentation tanks.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] This utility model provides, for example Figure 1-4The plum wine fermentation tank shown includes: a fermentation tank body 1, with a motor installed on the top of the fermentation tank body 1, and a stirring rod connected to the output end of the motor; a feed inlet 2, installed on one side of the top of the fermentation tank body 1, and a discharge outlet connected to the bottom of the fermentation tank body 1, through which raw materials are easily fed into the inner cavity of the fermentation tank body 1 for plum wine fermentation, and through which residues are easily discharged; a gas pipe 3, installed on the other side of the top of the fermentation tank body 1, through which a one-way exhaust device 4 is installed to guide the exhaust of gas; the one-way exhaust device 4... The one-way exhaust device 4 is installed inside the gas pipe 3. This device 4 is used to expel gas from the interior of the fermentation tank 1, thereby depressurizing the interior. The one-way exhaust device 4 enables automatic directional discharge of fermentation gas, effectively preventing backflow of external air, maintaining an anaerobic environment within the fermentation tank 1, preventing contamination by other microorganisms and oxidation of the wine, and ensuring the pure flavor of the plum wine. Simultaneously, this device can respond in real-time to changes in gas pressure within the fermentation tank 1, rapidly depressurizing during peak gas production periods, significantly reducing the risk of tank explosion and preventing splashing of fermentation liquid due to sudden pressure drops. Furthermore, the mechanical one-way exhaust design of the one-way exhaust device 4 is compact, low-cost, requires no electricity or sensors, and is not easily clogged by fruit pomace or sediment, making it suitable for long-term continuous fermentation. In addition, the self-depressurizing design reduces manual intervention and improves the stability of the fermentation process.

[0036] The one-way exhaust device 4 includes: an adjustable limiting mechanism 41, which is installed inside the trachea 3; an elastic sealing mechanism 42, which is slidably connected to the adjustable limiting mechanism 41; and a mounting ring 43, which is fixedly installed at the bottom of the inner cavity of the trachea 3. The elastic sealing mechanism 42 is used to seal the mounting ring 43. The adjustable limiting mechanism 41 facilitates the limiting of the elastic sealing mechanism 42, and the elastic sealing mechanism 42 is elastically sealed on the mounting ring 43, thereby facilitating the formation of a one-way seal in the inner cavity of the trachea 3.

[0037] The adjustable limiting mechanism 41 includes: a nut seat 411, which is disposed inside the air tube 3; a sleeve 412, the outer wall of which has an external thread and is threadedly engaged with the nut seat 411; a compression ring 413, which is connected to the bottom of the sleeve 412; and a bracket 414, multiple brackets 414 are arranged in a ring array and connected to the outer wall of the nut seat 411, and the nut seat 411 is fixedly installed inside the air tube 3 through the brackets 414. The adjustable limiting mechanism 41 further includes: a bolt rod 415, which is threadedly inserted into the top of the sleeve 412; and a limiting block 416, which is connected to the end of the bolt rod 415. The limiting block 416 is used to limit the insertion of the elastic sealing mechanism 42. Through the one-way connection between the nut seat 411 and the sleeve 412, it is easy to adjust the position of the compression ring 413 relative to the mounting ring 43 by rotating the thread of the sleeve 412, so as to adjust the elastic force of the spring 423 on the sealing block 422 by compressing and deforming the spring 423. The compression and deformation of the spring 423 facilitates the elastic support of the sealing block 422, so that the sealing block... The sealing effect of the mounting ring 43 is better by the bracket 414. The position of the nut seat 411 is easily fixed by the bracket 414. The threaded insertion between the bolt rod 415 and the sleeve 412 makes it easy to adjust the position of the limiting block 416 relative to the sleeve 412. This allows the limiting block 416 to limit the upper limit of the sliding of the limiting rod 421. When it is not necessary to vent the inner cavity of the fermenter body 1, the limiting block 416 is pressed against the limiting rod 421 by rotating the bolt rod 415, which restricts the upward movement of the limiting rod 421. This allows the sealing block 422 to stably seal the inner cavity of the mounting ring 43 and prevent gas leakage.

[0038] Furthermore, the elastic sealing mechanism 42 includes: a limiting rod 421, which is slidably inserted into the sleeve 412; a sealing block 422, which is connected to the end of the limiting rod 421; and a spring 423, which is movably sleeved on the outside of the limiting rod 421 and is disposed between the compression ring 413 and the sealing block 422. The bottom of the sealing block 422 is shaped like an inverted frustum, and the bottom of the sealing block 422 is wrapped with a rubber pad. The elastic deformation of the rubber pad helps to enhance the sealing performance between the sealing block 422 and the mounting ring 43. The sliding interlocking between the limiting rod 421 and the sleeve 412 makes the interlocking sliding of the limiting rod 421 more stable. The spring 423 provides elastic support for the sealing block 422. When the gas pressure inside the fermenter body 1 is greater than the atmospheric pressure, the gas pressure will push the sealing block 422 upward. After the spring 423 is compressed and deformed, the gas in the inner cavity of the fermenter body 1 can be discharged from the gap between the mounting ring 43 and the sealing block 422.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
