Description

Technical Field

[0001] This utility model relates to the field of barley fermentation technology, and in particular to a barley fermentation device. Background Technology

[0002] Barley wine is a traditional alcoholic beverage favored by the Tibetan people. It has a unique flavor and is usually brewed from barley as the main ingredient. Barley wine has a relatively low alcohol content, a mellow taste, and the distinctive aroma of barley. In Tibetan culture, barley wine holds an important place and often appears in various celebrations, gatherings, and traditional ceremonies. People use barley wine to entertain guests to express their enthusiasm and friendliness.

[0003] Patent publication number CN222574607U discloses a barley wine fermentation device, including a fermentation tank with a motor fixedly connected to the top. By rotating a handle clockwise, the handle drives a rotating column to rotate clockwise, which in turn drives a rotating plate to rotate clockwise. The rotating plate drives a moving column to move inward, which in turn drives a slider to move inward. The slider then drives a push block to move inward, releasing the pressure on the first sealing ring. The elastic first sealing ring then contracts and rebounds inward, releasing the seal on the feed pipe. Lifting the sealing cap upward releases the seal on the feed pipe. To reseal the feed pipe, the above steps are reversed. This device offers highly efficient sealing, preventing the entry of bacteria and air into the fermentation tank, thus maintaining the quality of the barley wine. The sealing mechanism effectively seals the feed pipe, improving the stability of the fermentation device.

[0004] When producing highland barley wine, the highland barley needs to be crushed and put into a fermentation tank for fermentation. The fermented wine contains a large amount of highland barley residue. However, the fermentation device in this patent lacks a filtration mechanism. When the fermented highland barley wine is discharged, the highland barley impurities will be discharged along with the wine from the outlet. These impurities can easily clog the outlet.

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a barley fermentation device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a barley fermentation device, comprising a fermentation tank, a filter cylinder fixedly connected inside the fermentation tank, a stirring element provided inside the filter cylinder, the stirring element being rotatably connected to the top surface of the fermentation tank, a feed pipe vertically fixed to the top surface of the fermentation tank, a sealing cap being threadedly connected to the outer circumference of the feed pipe, a sealing element being provided on the outer circumference of the filter cylinder, and a discharge valve being provided on the bottom surface of the fermentation tank.

[0007] As a further description of the above technical solution: the stirring component includes a drive motor vertically fixed at the center of the top surface of the fermentation tank, the output end of the drive motor is connected to a rotating shaft, the end of the rotating shaft rotates through the fermentation tank and extends into the filter cylinder, the end of the rotating shaft is rotatably connected to the bottom wall of the fermentation tank, and a plurality of equally spaced stirring rods are fixedly connected to the outer periphery of the rotating shaft.

[0008] As a further description of the above technical solution: the sealing element includes a support sleeve that rotates and fits against the top surface of the filter cylinder, and a plurality of equally spaced arc-shaped plates are fixedly connected to the bottom surface of the support sleeve. The arc-shaped plates are used to cover the filter holes on the filter cylinder. Two arc-shaped waist holes are opened on the top surface of the fermenter. A support shaft slides through the arc-shaped waist holes. A driving component is fixedly connected to the top surface of the support shaft. The driving component is slidably connected to the top surface of the fermenter.

[0009] As a further description of the above technical solution: the driving component includes a sealing ring fixedly connected to the top surface of the support shaft, an external toothed ring fixedly connected to the top surface of the sealing ring, a toothed rack meshing with the outer circumference of the external toothed ring, the toothed rack being slidably connected to the top surface of the fermenter, an electric push rod being horizontally fixed to the top surface of the fermenter, and the piston rod end of the electric push rod being fixedly connected to the end of the toothed rack.

[0010] As a further description of the above technical solution: a limiting ring is fixedly sleeved on the outer periphery of the feed pipe, the limiting ring is located on the bottom surface of the sealing cover, a plurality of first air holes are horizontally opened on the outer periphery of the sealing cover and distributed circumferentially at equal intervals, and a plurality of second air holes are horizontally opened on the outer periphery of the feed pipe and distributed circumferentially at equal intervals, the second air holes being located above the first air holes.

[0011] As a further description of the above technical solution: the feed pipe is located directly above the filter cylinder, and the discharge valve is located between the filter cylinder and the side wall of the fermenter.

[0012] As a further description of the above technical solution: a pressure sensor is fixedly connected to one side of the top wall of the fermenter, an indicator light is fixedly connected to the top surface of the sealing cover, a temperature sensor is fixedly connected to the other side of the top wall of the fermenter, a spiral heating wire is embedded in the inner wall of the fermenter, and the filter cartridge is made of thermally conductive metal material.

[0013] This utility model has the following beneficial effects:

[0014] 1. Compared with existing technologies, this highland barley fermentation device effectively solves the problem of mixed discharge of alcohol and impurities in traditional highland barley fermentation devices by fixing a filter cylinder inside the fermentation tank. Specifically, during fermentation, impurities such as highland barley residue are confined inside the filter cylinder, while the alcohol permeates through the filter holes into the cavity between the filter cylinder and the inner wall of the fermentation tank. After fermentation, the clarified alcohol can be directly discharged by opening the discharge valve, avoiding impurities from clogging the discharge port or mixing into the finished product. The setting of the stirring component further optimizes the filtration effect: the stirring rod rotates continuously under the drive motor, which not only fully mixes the highland barley raw materials and fermentation agent and improves the uniformity of fermentation, but also prevents the filter holes from clogging and accelerates the separation of alcohol through mechanical disturbance during the filtration stage. This integrated filtration design eliminates the need for subsequent additional filtration processes, maintaining the traditional flavor of highland barley wine while significantly improving production efficiency and the purity of the alcohol, making it particularly suitable for small-batch or continuous production scenarios.

[0015] 2. Compared with existing technologies, this barley fermentation device ensures the hygiene and stability of the barley fermentation process through multiple sealing mechanisms and intelligent environmental monitoring. The feed pipe adopts a threaded sealing cap structure, combined with a limiting ring for fixation, achieving physical sealing of the feed inlet. The first and second air holes corresponding to the sealing cap and feed pipe can be aligned by rotating the sealing cap to allow limited ventilation when needed, balancing the air pressure inside and outside the tank, preventing excessive internal pressure caused by fermentation gas production, and reducing the risk of contamination by bacteria. The sealing element on the outer periphery of the filter cartridge further enhances hygiene protection: The electric push rod drives the rack to move, which in turn moves the outer toothed ring and the support sleeve, allowing the arc-shaped plate to precisely cover or expose the filter holes of the filter cylinder. In the early stage of fermentation, the arc-shaped plate closes the filter holes to prevent impurities from overflowing. In the later stage of fermentation or during drainage, the arc-shaped plate opens the filter holes to ensure smooth separation of the liquor. In addition, the combination of temperature sensor and spiral heating wire enables precise control of fermentation temperature, and the linkage between pressure sensor and indicator light can monitor the pressure status inside the tank in real time. These designs work together to maintain a constant temperature, sealed, and clean fermentation environment, inhibit the growth of miscellaneous bacteria, and improve the consistency and safety of highland barley wine.

Detailed Implementation

[0025] 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.

[0026] Reference Figures 1 to 7This utility model provides a barley fermentation device comprising: a fermentation tank 1, a filter cylinder 7 fixedly connected inside the fermentation tank 1, a stirring element inside the filter cylinder 7 rotatably connected to the top surface of the fermentation tank 1, a feed pipe 12 vertically fixed to the top surface of the fermentation tank 1, a sealing cap 15 threadedly connected to the outer circumference of the feed pipe 12, a sealing element on the outer circumference of the filter cylinder 7, a discharge valve 10 on the bottom surface of the fermentation tank 1, the feed pipe 12 located directly above the filter cylinder 7, the discharge valve 10 located between the filter cylinder 7 and the side wall of the fermentation tank 1, and a limiting ring fixedly fitted around the outer circumference of the feed pipe 12. 13. The limiting ring 13 is located on the bottom surface of the sealing cover 15. Multiple first air holes 14 are horizontally and equidistantly distributed along the circumferential direction on the outer periphery of the sealing cover 15. Multiple second air holes 17 are horizontally and equidistantly distributed along the circumferential direction on the outer periphery of the feed pipe 12. The second air holes 17 are located above the first air holes 14. A pressure sensor 21 is fixedly connected to one side of the top wall of the fermenter 1. An indicator light 16 is fixedly connected to the top surface of the sealing cover 15. A temperature sensor is fixedly connected to the other side of the top wall of the fermenter 1. A spiral heating wire is embedded in the inner wall of the fermenter 1. The filter cylinder 7 is made of thermally conductive metal material.

[0027] The stirring component includes a drive motor 5 vertically fixed at the center of the top surface of the fermentation tank 1. The output end of the drive motor 5 is connected to a rotating shaft 9. The end of the rotating shaft 9 rotates through the fermentation tank 1 and extends into the filter cylinder 7. The end of the rotating shaft 9 is rotatably connected to the bottom wall of the fermentation tank 1. Multiple equidistant stirring rods 8 are fixedly connected to the outer periphery of the rotating shaft 9.

[0028] The sealing element includes a support sleeve 6 that rotates and fits against the top surface of the filter cylinder 7. The bottom surface of the support sleeve 6 is fixedly connected to multiple equally spaced arc-shaped plates 18. The arc-shaped plates 18 are used to cover the filter holes on the filter cylinder 7. Two arc-shaped waist holes 19 are opened on the top surface of the fermenter 1. A support shaft 20 slides through the arc-shaped waist holes 19. A drive component is fixedly connected to the top surface of the support shaft 20. The drive component is slidably connected to the top surface of the fermenter 1.

[0029] The driving component includes a sealing ring 11 fixedly connected to the top surface of the support shaft 20, an external toothed ring 4 fixedly connected to the top surface of the sealing ring 11, a toothed rack 3 meshing with the outer periphery of the external toothed ring 4, the rack 3 being slidably connected to the top surface of the fermenter 1, an electric push rod 2 being horizontally fixed to the top surface of the fermenter 1, and the piston rod end of the electric push rod 2 being fixedly connected to the end of the rack 3.

[0030] Working principle: The crushed barley raw material and fermentation agent are fed into the device through the feed pipe 12. After feeding, the sealing cap 15 is tightened to ensure a tight connection with the feed pipe 12 via threads. At this time, the first air hole 14 on the sealing cap 15 and the second air hole 17 on the feed pipe 12 are misaligned, and the feed inlet is completely sealed, effectively isolating external air and bacteria. Then, the electric push rod 2 is activated, pushing the rack 3 to move horizontally. The rack 3 drives the meshing outer toothed ring 4 to rotate, and the outer toothed ring 4 drives the lower support sleeve 6 to rotate synchronously through the support shaft 20. The multiple arc-shaped plates 18 fixed on the bottom surface of the support sleeve 6 rotate accordingly, so that their arc surfaces completely cover the filter holes on the wall of the filter cylinder 7. At this time, the filter... The interior of cylinder 7 becomes a relatively independent fermentation chamber, completely blocking solid impurities. The fermented liquor temporarily accumulates inside the cylinder and mixes with the materials. The drive motor 5 is activated, causing the rotating shaft 9 and multiple stirring rods 8 fixed on the shaft 9 to rotate at a uniform speed. The stirring rods 8 continuously and gently agitate the barley material inside the filter cylinder 7. This action achieves three key objectives: ensuring uniform contact between the barley fragments, fermenting agent (such as yeast), and water; initiating and accelerating the fermentation reaction; promoting uniform heat distribution within the fermentation tank 1; and, in conjunction with temperature sensor monitoring and spiral heating wires, precisely maintaining the optimal constant temperature environment required for barley fermentation. Dynamic agitation prevents the barley material from settling and caking, preserving the material's properties. The loose material facilitates the escape of carbon dioxide produced during fermentation and the subsequent seepage of the wine. When the fermentation process is basically complete and wine separation is required, the control seal is opened, the electric push rod 2 moves in the opposite direction, and through the rack 3 and the outer toothed ring 4, it drives the support sleeve 6 and the arc plate 18 to rotate in the opposite direction, causing the arc plate 18 to move away, completely exposing the filter holes on the filter cylinder 7. Under the continuous gentle stirring of the stirring rod 8, the wine in the filter cylinder 7 seeps through the filter holes under the action of gravity and slight centrifugation, and enters the annular cavity between the filter cylinder 7 and the inner wall of the fermentation tank 1. The stirring action also plays a "self-cleaning" role to prevent the filter holes from being instantly blocked by fine residue. After the clarified wine collects at the bottom of the fermentation tank 1, the discharge valve 10 is opened, that is... The pure barley wine can be discharged, while most of the barley residue is retained in the filter cartridge 7, achieving efficient online solid-liquid separation and completely solving the problem of impurities clogging the outlet and affecting the quality of the wine. During the peak of fermentation and gas production, the pressure inside the tank may rise. At this time, the sealing cap 15 can be manually rotated so that the first vent 14 on it is aligned with the second vent 17 on the feed pipe 12, forming a limited ventilation channel. This can slowly release excess gas, balance the air pressure inside and outside the tank, and prevent excessive pressure from impacting the equipment's sealing performance. At the same time, because the channel is narrow and tortuous, it can minimize the risk of contamination caused by a large amount of external air entering. The pressure sensor 21 monitors the pressure changes at the top of the fermentation tank 1 in real time.When the pressure exceeds a preset safety threshold (for example, excessive gas production in a sealed state without timely manual venting), the sensor sends a signal to illuminate the indicator light 16 on the top of the sealing cap 15, reminding the operator to adjust the gas pressure promptly (manually aligning the vents or checking the process) to ensure operational safety. The temperature sensor and the spiral heating wire form a closed-loop temperature control system, ensuring that the fermentation process is always within the optimal temperature range. This is crucial for ensuring the consistency of the highland barley wine's flavor and fermentation efficiency.
