Abstract
Description
Technical Field
[0001] This utility model relates to the field of beer processing technology, and in particular to a beer beverage fermentation and stirring device. Background Technology
[0002] In the beer and beverage manufacturing industry, fermentation is a crucial step that determines the final quality and flavor of the product. Fermentation involves not only the conversion of sugars in the raw materials by microorganisms, but also the combined effects of various factors such as temperature, pressure, oxygen content, and agitation. Among these, agitation, as an important operation in the fermentation process, plays a vital role in promoting the uniform mixing of various components in the fermentation broth, improving the contact efficiency between microorganisms and the substrate, controlling the fermentation temperature, and preventing problems such as localized overheating or excessive concentration gradients.
[0003] Existing beer fermentation equipment cannot be stirred during use, resulting in poor mixing of raw materials and uneven fermentation, which affects the quality of beer. In addition, it is not easy to control the pressure inside the tank, resulting in poor fermentation effect.
[0004] An existing patent (publication number: CN220703609U) discloses a beer fermentation device, including a support rod. A pressure control component is fixedly installed on the upper surface of the support rod. A fermentation component is fixedly connected to one end of the outer surface of the pressure control component. A sealing cap is fixedly connected to the upper surface of the fermentation component. A groove is formed on the upper surface of the sealing cap, and a motor housing is fixedly connected inside the groove. In this beer fermentation device, through the setting of the pressure control component, when in use, an external power source starts a servo motor, which drives a threaded rod to rotate through a first transmission rod, causing a moving plate to move inside the gas cylinder. This facilitates the adjustment of the pressure inside the fermentation component, improving the fermentation effect. Through the setting of the stirring component, when in use, an external power source starts a drive motor, which drives a rotating rod to rotate through a second transmission rod, causing the stirring rod to rotate. This facilitates the stirring of materials at any time, improving the mixing degree of raw materials.
[0005] To address the aforementioned issues, existing patents have provided solutions, but these solutions suffer from the problem that beer fermentation with stirring easily produces a large amount of foam, leading to the overflow of raw materials and affecting quality. Furthermore, existing fermentation devices cannot eliminate the foam generated during the stirring process.
[0006] Therefore, a beer and beverage fermentation stirring device is proposed. Utility Model Content

[0028] 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.
[0029] Please see Figures 1 to 5 This utility model provides a technical solution:
[0030] A beer beverage fermentation and stirring device includes a support frame 1, a lifting plate 2 in the middle of the support frame 1, an installation frame 3 on the side wall of the lifting plate 2, a fermentation tank 4 on one side of the support frame 1, a stirring mechanism 5 in the middle of the installation frame 3, and a positioning mechanism 6 at the bottom of the installation frame 3.
[0031] The stirring mechanism 5 includes a first motor 51 mounted on the top of the mounting frame 3. The output end of the first motor 51 is fixedly connected to a stirring shaft 52. A stirring disc 53 is mounted on the bottom of the stirring shaft 52. Multiple stirring teeth 54 are provided on the side wall of the stirring disc 53. A rotating cylinder 55 is connected to the bottom bearing of the mounting frame 3. The stirring shaft 52 is located inside the rotating cylinder 55. Four impact plates 56 are mounted on the bottom of the rotating cylinder 55. Multiple breaking holes 57 are opened on the side wall of the impact plates 56. A drive assembly 58 is mounted on the top of the rotating cylinder 55.
[0032] Specifically, such as Figure 4 As shown, the drive assembly 58 includes a drive wheel 581 disposed on the top of the rotating cylinder 55, a second motor 582 disposed on the top of the mounting bracket 3, a drive wheel 583 fixedly connected to the output end of the second motor 582, and a transmission belt 584 disposed between the drive wheel 583 and the drive wheel 581.
[0033] Specifically, such as Figure 3 As shown, an electric push rod 8 is provided on the top of the support frame 1, and the output end of the electric push rod 8 is fixedly connected to the lifting plate 2.
[0034] Specifically, such as Figure 3 As shown, two guide rods 9 are fixedly connected to the inner wall of the support frame 1, and the lifting plate 2 is movably connected to the guide rods 9.
[0035] The electric push rod 8 drives the lifting plate 2 to move vertically along the guide rod 9, causing the mounting frame 3 and the bottom positioning mechanism 6 to descend, so that the lid 62 accurately covers the opening of the fermentation tank 4. The first motor 51 drives the stirring shaft 52 to rotate, causing the stirring plate 53 and the side wall stirring teeth 54 to rotate and stir and mix the fermentation liquid, promoting uniform contact between yeast and wort and accelerating sugar conversion. The second motor 582 drives the rotating drum 55 to rotate at high speed through the drive wheel 583, the transmission belt 584 and the drive wheel 581, making it rotate in the opposite direction to the stirring shaft 52. During the rotation of the four impact plates 56 at the bottom, the foam layer on the liquid surface is cut, and the foam impacts the foam. The plate 56 ruptures under the shear force and the local negative pressure generated by the burst hole 57. Gas is discharged through the burst hole 57, and the liquid flows back to the fermentation liquid, achieving physical defoaming without chemical residue. The electric push rod 8 adjusts the height of the stirring mechanism 5 in real time, so that the impact plate 56 is always below the liquid surface, adapting to the liquid surface fluctuations during the fermentation process and ensuring stable defoaming efficiency. Thus, through the setting of the stirring mechanism 5, the asynchronous rotation of the stirring shaft 52 and the rotating cylinder 55 achieves thorough stirring and mixing of yeast and wort, and can shear and burst the foam generated by stirring, avoiding excessive foam that would cause wort overflow and affect the fermentation quality of beer.
[0036] Specifically, such as Figure 4 As shown, the positioning mechanism 6 includes two connecting rods 61 located at the bottom of the mounting frame 3. A bucket lid 62 is fixedly connected to the bottom of the connecting rods 61. The bucket lid 62 is adapted to the fermentation bucket 4. A limit component 63 is provided on the side wall of the support frame 1.
[0037] Specifically, such as Figure 4 As shown, the limiting component 63 includes a mounting plate 631 disposed on the side wall of the support frame 1. Two limiting blocks 632 are hinged to the side wall of the mounting plate 631. The side wall of the limiting block 632 is arc-shaped and contacts the fermentation tank 4.
[0038] Specifically, such as Figure 4 As shown, a protective pad 7 is provided on the side wall of the limiting block 632. The protective pad 7 is made of rubber and is arc-shaped.
[0039] Specifically, such as Figure 4 As shown, the bottom of the bucket lid 62 is provided with two limiting rings 10, which are located on both sides of the fermentation bucket 4.
[0040] First, the fermentation tank 4 is moved to one side of the support frame 1 so that the fermentation tank 4 comes into contact with the limiting block 632, thereby limiting the distance between the fermentation tank 4 and the support frame 1. The protective pad 7 is used to prevent rigid collision between the fermentation tank 4 and the limiting block 632. The electric push rod 8 drives the lifting plate 2 to descend, which in turn moves the mounting frame 3 and the bottom positioning mechanism 6 down as a whole, so that the lid 62 covers the opening of the fermentation tank 4. At the same time, the two limiting rings 10 at the bottom of the lid 62 are engaged with the two sides of the outer wall of the fermentation tank 4 to position the fermentation tank 4 and prevent the fermentation tank 4 from shifting or the seal from failing during the stirring process.
[0041] By adopting the above technical solution, the problem that existing beer fermentation equipment easily produces a lot of foam when stirring the beer during fermentation, which leads to the overflow of raw materials and affects the quality, and the problem that existing fermentation equipment cannot eliminate the foam generated during stirring.
[0042] Working principle: In use, the fermentation tank 4 is first moved to one side of the support frame 1, so that the fermentation tank 4 contacts the limiting block 632, thereby limiting the distance between the fermentation tank 4 and the support frame 1. The electric push rod 8 drives the lifting plate 2 to descend, which in turn moves the mounting frame 3 and the bottom positioning mechanism 6 downward as a whole, so that the lid 62 covers the opening of the fermentation tank 4. At the same time, the two limiting rings 10 at the bottom of the lid 62 are engaged with the two sides of the outer wall of the fermentation tank 4, forming a positioning of the fermentation tank 4. The first motor 51 drives the stirring shaft 52 to rotate, which drives the stirring plate 53 and the side wall to stir. The rotating gear 54 agitates and mixes the fermentation liquid, promoting uniform contact between yeast and wort and accelerating sugar conversion. The second motor 582 drives the rotating drum 55 to rotate at high speed through the drive wheel 583, transmission belt 584 and drive wheel 581, making it rotate in the opposite direction to the stirring shaft 52. During the rotation of the four impact plates 56 at the bottom, the foam layer on the liquid surface is cut. The foam breaks under the shear force of the impact plate 56 and the local negative pressure generated by the bursting hole 57. The gas is discharged through the bursting hole 57 and the liquid flows back to the fermentation liquid, achieving physical defoaming without chemical residue.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
