Abstract
Description
Technical Field
[0001] This utility model relates to the field of fruit wine brewing, and more specifically, to a fermentation device suitable for Jaboticaba fruit wine brewing. Background Technology
[0002] Compared to conventional grapes, jaboticaba grapes have lighter skins. In the early stages of fermentation, because the skins are relatively light and may have a higher concentration of wild yeasts and other microorganisms on their surface, these microorganisms produce bubbles during fermentation, causing the skins to float to the surface of the fermentation liquid, forming a layer known as a "cap." However, during the winemaking process, the pigments, flavor compounds, and nutrients from the skins need to dissolve into the wine. The skins floating on the surface prevent them from fully contacting the fermentation liquid, thus affecting the fermentation efficiency of jaboticaba. Furthermore, because jaboticaba wine fermentation produces a large amount of alcohol and carbon dioxide, leading to excessively high pressure inside the container, it is necessary to manually release the gas periodically. Utility Model Content
[0003] In view of this, the present invention provides a fermentation device suitable for jaboticaba wine brewing that allows the peel of jaboticaba fruit to be fully immersed in the fermentation liquid and keeps the air pressure inside the container at a reasonable value.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A fermentation apparatus suitable for jaboticaba wine making includes a hollow tank, a jacket fitted around the outer periphery of the tank, a drive assembly located on the top outer side of the tank, and an agitator located inside the tank. A hollow partition is formed between the inner wall of the jacket and the outer wall of the tank, and the partition communicates with the interior of the tank. The outer wall of the jacket is also provided with a pressure relief assembly communicating with the partition. The agitator includes a rotating shaft connected to the output end of the drive assembly, a blade assembly located at the bottom of the rotating shaft, and a pressure plate located in the middle of the rotating shaft, the pressure plate being inclined.
[0006] In the above technical solution, the hollow partition formed between the jacket and the tank body allows for the convenient introduction of heating or cooling media, enabling precise control of the fermentation broth temperature. This helps maintain the optimal temperature environment during fermentation. Furthermore, the pressure relief components installed on the outer wall of the jacket can effectively regulate the pressure within the partition, preventing abnormal pressure caused by factors such as temperature changes and ensuring the safe operation of the fermentation process.
[0007] Furthermore, the rotating shaft, blade assembly, and inclined pressure plate within the tank's agitator work together to create a multi-layered stirring effect. The blade assembly directly acts on the fermentation broth, promoting oxygen dissolution and uniform distribution of nutrients. The pressure plate's wave-like undulating motion during rotation continuously immerses the jaboticaba peel floating on the surface of the fermentation broth into it, thus rapidly releasing substances from the peel into the broth, significantly shortening fermentation time and improving fermentation efficiency.
[0008] Optionally, in one possible implementation, the pressure relief assembly includes a pressure relief tank with a top opening, a cover movably fitted onto the opening, and a reset unit for connecting the pressure relief tank and the cover, the reset unit being able to reset the cover after displacement, and the pressure relief tank and the jacket being connected by a connecting pipe.
[0009] In the above technical solution, the reset unit in the pressure relief assembly is ingeniously designed. When the pressure inside the tank and partition rises abnormally, it automatically pushes the cover open to achieve rapid pressure relief and prevent safety accidents caused by overpressure. Once the pressure returns to normal, the reset unit can automatically reset the cover, tightly sealing the pressure relief tank, preventing gas leakage during fermentation and maintaining the stability of the fermentation environment.
[0010] Optionally, in one possible implementation, the reset unit includes a bracket fixedly disposed inside the pressure relief tank, a connecting rod detachably disposed on the cover and movably inserted into the bracket, and an elastic element sleeved on the connecting rod. The end of the connecting rod is provided with a limiting block, and the elastic element is located between the limiting block and the bracket.
[0011] In the above technical solution, the reset unit forms a stable and reliable reset mechanism through the combination of a bracket, a connecting rod, and an elastic element. When the pressure inside the partition increases and pushes the cover to move, the connecting rod moves accordingly, compressing the elastic element. Once the pressure decreases, the restoring force of the elastic element will push the connecting rod and the cover to reset, ensuring the sealing after pressure relief and avoiding pressure leakage or sealing failure caused by improper reset.
[0012] Alternatively, in one possible implementation, the elastic element is a metal spring or elastic rubber.
[0013] In the above technical solutions, both metal springs and elastic rubber have excellent elasticity and restoring force, and can quickly return to their original shape after being compressed, providing stable and reliable reset power for the cover.
[0014] Optionally, in one possible implementation, the reset unit includes a bracket fixedly disposed inside the pressure relief tank, a connecting rod movably inserted into the bracket, and a counterweight, wherein the two ends of the connecting rod are detachably connected to the cover and the counterweight, respectively.
[0015] In the above technical solution, the cover and counterweight are connected by a connecting rod, and the weight of the counterweight is used as the reset force, realizing a simple and effective reset mechanism. This eliminates the need for complex mechanical structures or electronic components, reducing manufacturing costs and improving system reliability. Furthermore, by replacing counterweights of different weights, the opening pressure threshold of the reset unit can be easily adjusted to adapt to different fermentation process requirements.
[0016] Optionally, in one possible implementation, a sealing gasket is provided at the part of the cover that contacts the pressure relief tank.
[0017] In the above technical solution, the sealing gasket, as a buffer medium between the cover and the pressure relief tank, can effectively isolate external air, moisture and impurities, ensuring the purity and stability of the fermentation environment.
[0018] Optionally, in one possible implementation, the tank body is provided with an air trough communicating with the partition.
[0019] In the above technical solution, the gas trough serves as a channel connecting the tank and the clamping trough, allowing the gas inside the tank to smoothly enter the partition or pressure relief component. By controlling the position of the gas trough, the fermentation liquid can be prevented from entering the partition. The structure is simple and effective.
[0020] Optionally, in one possible implementation, the drive assembly includes a mounting bracket disposed on the tank body and a rotary drive fixed to the mounting bracket, one end of the rotating shaft extending to the outside of the tank body and connected to the output end of the rotary drive via a coupling.
[0021] In the above technical solution, the mounting bracket design allows the rotary drive component to be securely fixed to the tank body, while facilitating installation and disassembly. When maintenance or replacement of the drive assembly is required, the rotary drive component can be easily removed from the tank body simply by disassembling the coupling, reducing maintenance costs and time.
[0022] Alternatively, in one possible implementation, the top of the tank is provided with a feed inlet.
[0023] In the above technical solution, the design of the feed inlet allows materials to be easily added into the tank without complicated operations or additional equipment, which greatly improves production efficiency, reduces the difficulty of operation, and makes the fermentation process smoother.
[0024] Optionally, in one possible implementation, the bottom of the tank is provided with a liquid outlet pipe and a slag outlet.
[0025] In the above technical solution, the setting of the liquid outlet pipe and the slag outlet allows the liquid and solid residues after fermentation to be discharged separately, achieving efficient separation. This not only improves the purity of the product but also reduces the complexity and cost of subsequent processing. Attached Figure Description

Detailed Implementation
[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0032] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0033] Please refer to Figure 1This embodiment provides a fermentation device suitable for jaboticaba wine brewing, including a hollow tank 1, a jacket 2 fitted around the outer periphery of the tank 1, a drive assembly 3 located on the top outer side of the tank 1, and an agitator 4 located inside the tank 1; a hollow partition 5 is formed between the inner side wall of the jacket 2 and the outer side wall of the tank 1, and the partition 5 communicates with the interior of the tank 1; the outer side wall of the jacket 2 is also provided with a pressure relief assembly 6 communicating with the partition 5; the agitator 4 includes a rotating shaft 41 connected to the output end of the drive assembly 3, a blade assembly 42 located at the bottom of the rotating shaft 41, and a pressure plate 43 located in the middle of the rotating shaft 41, the pressure plate 43 being inclined.
[0034] In this embodiment, the hollow partition 5 formed between the jacket 2 and the tank 1 allows for the convenient introduction of heating or cooling media, such as water or ethylene glycol solution, to precisely control the temperature of the fermentation broth. This helps maintain the optimal temperature environment during fermentation. Furthermore, the pressure relief component 6 installed on the outer wall of the jacket 2 effectively regulates the pressure within the partition 5, preventing pressure anomalies caused by temperature changes and ensuring the safe operation of the fermentation process. Of course, even without adding media to the jacket 2, the partition 5 still provides some insulation. Additionally, the media should not completely fill the partition 5; it should contain both liquid and gaseous components so that gas can effectively enter the pressure relief component 6.
[0035] Furthermore, the rotating shaft 41, blade assembly 42, and inclined pressure plate 43 within the stirring assembly 4 inside tank 1 work together to create a multi-layered stirring effect. The blade assembly 42 directly acts on the fermentation liquid, promoting oxygen dissolution and uniform distribution of nutrients. The pressure plate 43, during rotation, exhibits a wave-like undulating motion, continuously immersing the jaboticaba peel floating on the surface of the fermentation liquid into it. This allows substances on the peel to be rapidly released into the fermentation liquid, significantly shortening the fermentation time and improving fermentation efficiency.
[0036] It should be noted that the pressure plate 43 is a circular plate structure, with its center fixed to the rotating shaft 41, and the pressure plate 43 is inclined relative to the horizontal plane. There are two or more blade groups 42, spaced apart along the length of the rotating shaft 41. Each blade group 42 includes multiple stirring blades, which are spaced apart circumferentially along the rotating shaft 41. Furthermore, in this embodiment, the middle portion of the rotating shaft 41 is between one-third and two-thirds of its overall length, and the bottom portion is less than one-third of its overall length.
[0037] In this embodiment, the pressure relief assembly 6 includes a pressure relief tank 61 with a top opening, a cover 62 that can be movably closed to the opening, and a reset unit 63 for connecting the pressure relief tank 61 and the cover 62. The reset unit 63 can reset the cover 62 after it has been moved. The pressure relief tank 61 and the jacket 2 are connected by a connecting pipe 64.
[0038] The reset unit 63 in the pressure relief assembly 6 is ingeniously designed. When the pressure in the tank 1 and the partition 5 rises abnormally, it automatically pushes the cover 62 to open, achieving rapid pressure relief and preventing safety accidents caused by overpressure. Once the pressure returns to normal, the reset unit 63 can automatically reset the cover 62, tightly sealing the pressure relief tank 61, preventing gas leakage during fermentation and maintaining the stability of the fermentation environment.
[0039] The reset function of the reset unit 63 in this embodiment can be implemented through various structures, as detailed below.
[0040] Please refer to Figure 2 The first structure is as follows: The reset unit 63 includes a bracket 631 fixedly installed inside the pressure relief tank 61, a connecting rod 632 detachably installed on the cover 62 and movably inserted into the bracket 631, and an elastic element 633 sleeved on the connecting rod 632. A limiting block 6321 is provided at the end of the connecting rod 632, and the elastic element 633 is located between the limiting block 6321 and the bracket 631. The bracket 631 includes a horizontal mounting plate and multiple support columns arranged at intervals below the mounting plate. The limiting block 6321 is located below the mounting plate, the connecting rod 632 movably passes through the mounting plate, and the elastic element 633 is located between the mounting plate and the limiting block 6321.
[0041] The aforementioned reset unit 63, through the combination of bracket 631, connecting rod 632, and elastic element 633, forms a stable and reliable reset mechanism. When the pressure inside the partition 5 increases, pushing the cover 62 to move, the connecting rod 632 moves accordingly, compressing the elastic element 633. Once the pressure decreases, the restoring force of the elastic element 633 will push the connecting rod 632 and the cover 62 to reset, ensuring the sealing after pressure relief and avoiding pressure leakage or sealing failure caused by improper reset.
[0042] It should be noted that the elastic element 633 is either a metal spring or elastic rubber. Both metal springs and elastic rubber possess excellent elasticity and restoring force, enabling them to quickly return to their original shape after being compressed, providing a stable and reliable reset force for the cover 62. In this embodiment, a metal spring is preferred.
[0043] Please refer to Figure 3 The second structure is as follows: The reset unit 63 includes a bracket 631 fixedly installed inside the pressure relief tank 61, a connecting rod 632 movably inserted into the bracket 631, and a counterweight 65. The two ends of the connecting rod 632 are detachably connected to the cover 62 and the counterweight 65, respectively. Similarly, the bracket 631 includes a horizontal mounting plate and multiple support columns arranged below the mounting plate. The multiple support columns are spaced apart. The connecting rod 632 movably passes through the mounting plate, and the two ends of the connecting rod 632 are threadedly connected to the cover 62 and the counterweight 65, respectively.
[0044] The aforementioned reset unit 63 connects the cover 62 to the counterweight 65 via a connecting rod 632. Utilizing the gravity of the counterweight 65 as the reset force, a simple and effective reset mechanism is achieved, eliminating the need for complex mechanical structures or electronic components, thus reducing manufacturing costs and improving system reliability. Specifically, the gravity of the counterweight 65 keeps the cover 62 closed when no external force is applied, naturally regulating the pressure within the partition 5. When the pressure within the partition 5 rises to a certain level, the cover 62 is pushed open to release the pressure; once the pressure decreases, the gravity of the counterweight 65 drives the cover 62 to reset, requiring no additional energy input. Furthermore, by replacing the counterweight 65 with different weights, the opening pressure threshold of the reset unit 63 can be easily adjusted to adapt to different fermentation process requirements.
[0045] In this embodiment, a sealing gasket 66 is provided at the contact point between the cover 62 and the pressure relief tank 61. The sealing gasket 66 serves as a buffer medium between the cover 62 and the pressure relief tank 61, effectively isolating external air, moisture, and impurities to ensure a pure and stable fermentation environment.
[0046] In this embodiment, the tank body 1 is provided with an air groove 11 that communicates with the partition 5. The air groove 11 should be located near the upper part of the tank body 1 and should be higher than the liquid level of the fermentation liquid to prevent the fermentation liquid from entering the jacket 2.
[0047] In this embodiment, the air trough 11 serves as a channel connecting the tank 1 and the clamping groove, allowing gas from the tank 1 to smoothly enter the partition 5 or the pressure relief assembly 6. By controlling the position of the air trough 11, fermentation liquid can be prevented from entering the partition 5. The structure is simple and effective. Of course, as another implementation, multiple air holes can also be used to connect the interior of the tank 1 and the partition 5.
[0048] In this embodiment, the drive assembly 3 includes a mounting bracket 31 mounted on the tank body 1 and a rotary drive component 32 fixed on the mounting bracket 31. One end of the rotating shaft 41 extends to the outside of the tank body 1 and is connected to the output end of the rotary drive component 32 via a coupling 321. The rotary drive component 32 can be a motor, rotary cylinder, hydraulic motor, or pneumatic motor, etc., and a suitable drive method is selected according to specific requirements.
[0049] The design of the mounting bracket 31 allows the rotary drive component 32 to be securely fixed to the tank 1, while also facilitating installation and removal. When maintenance or replacement of the drive assembly 3 is required, the rotary drive component 32 can be easily removed from the tank 1 simply by disassembling the coupling 321, reducing maintenance costs and time.
[0050] In this embodiment, the top of the tank body 1 is provided with a feed inlet 12, and the bottom of the tank body 1 is provided with a liquid outlet 13 and a slag outlet 14.
[0051] It should be noted that the design of the feed inlet 12 allows materials to be easily added into the tank 1 without complicated operations or additional equipment, greatly improving production efficiency, reducing operational difficulty, and making the fermentation process smoother. The liquid outlet 13 and slag outlet 14 allow the liquid and solid residues after fermentation to be discharged separately, achieving efficient separation. This not only improves the purity of the product but also reduces the complexity and cost of subsequent processing.
