Description

Technical Field

[0001] The present invention relates to the technical field of microbial fermentation tanks, and in particular to a high-efficiency fermentation device for producing plant beverages. Background Art

[0002] For some fermentation substrates (plant materials) that are relatively thick and unevenly distributed among the microorganisms, stirring is essential. For example, when preparing certain fruit pulp fermented beverages containing a large amount of pulp, stirring allows the microorganisms to fully contact the substrate, ensuring that heat and nutrients (such as carbon and nitrogen sources) are evenly distributed throughout the fermentation system, and ensuring the synchronization and stability of the fermentation. For most plant-based beverage fermentations, the microorganisms enter the logarithmic growth phase 6-12 hours after inoculation. During this period, stirring can fully utilize the microbial activity and promote fermentation. However, excessive stirring should be avoided during the delay period when the microorganisms are adapting to the new environment and during the late fermentation period (stable or decay period).

[0003] To this end, the Chinese patent with authorization announcement number CN118460341B discloses a special fermentation tank for producing plant-based organic acid fermentation puree with high bioavailability. By setting a reversing component and a pressure stabilization component, the fermentation tank can automatically change the rotation direction of the stirring shaft during the air pressure balance of the fermentation tank, thereby breaking the regularity of stirring in the fermentation tank and effectively improving the uniformity and bioavailability of the microbial fermentation environment.

[0004] However, for some plant-based beverage fermentations that require oxygen, such as using acetic acid bacteria to ferment plant juice to make fruit vinegar, sufficient oxygen is needed to oxidize ethanol to acetic acid during the fermentation process. Therefore, the fermentation tank cannot be completely sealed. Therefore, it is also impossible to control the stirring device by changing the air pressure. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention realizes the function of controlling the opening and closing of the stirring device according to temperature changes through a fermentation tank, a stirring device and a driving device. When the temperature sensor senses that the temperature is higher than the threshold, the connecting component connects the driving end of the rotary driver and the main shaft, and the rotary driver drives the main shaft and the stirring frame to rotate; when the temperature sensor senses that the temperature is lower than the threshold, the connecting component disconnects the driving end of the rotary driver and the main shaft.

[0017] 2. The present invention utilizes a connecting block, a first rotating shaft, a stirring blade, a temperature sensing assembly, and an adjustment assembly to adjust the stirring blade's inclination angle according to the temperature within the fermenter. During the fermentation process, when the temperature within the fermenter rises, the temperature sensing assembly drives the first rotating shaft via the adjustment assembly, which in turn drives the stirring blade, increasing its lateral pushing area and thereby improving stirring efficiency. Conversely, when the temperature drops, the adjustment mechanism gradually resets the stirring blade, reducing stirring efficiency.

If they come into direct contact with the driving parts, they may erode the surface of the parts, causing the main shaft and the regulating mechanism to rust, damage or jam, thereby affecting their normal operation. The isolation effect of the protective shell greatly reduces the risk of equipment failure caused by raw material erosion, thereby improving the stability of the equipment operation.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figure 1-Figure 3 : A high-efficiency fermentation equipment for producing plant beverages, comprising a fermentation tank 1, a stirring device 2 and a driving device 3; a temperature sensor 11 is provided in the fermentation tank 1; the stirring device 2 comprises a main shaft 21 and a stirring frame 22, the main shaft 21 is rotatably arranged on the fermentation tank 1, the stirring frame 22 is sleeved on the main shaft 21, and the stirring frame 22 is located inside the fermentation tank 1; the driving device 3 comprises a bracket 31 and a connecting component 32, the bracket 31 is arranged on the fermentation tank 1, and a rotating driver 311 is provided on the bracket 31, and the driving end of the rotating driver 311 is transmission-connected to the main shaft 21 through the connecting component 32; in working state, when the temperature sensor 11 senses that the temperature is higher than the threshold value, the connecting component 32 connects the driving end of the rotating driver 311 and the main shaft 21, and the rotating driver 311 drives the main shaft 21 and the stirring frame 22 to rotate; when the temperature sensor 11 senses that the temperature is lower than the threshold value, the connecting component 32 disconnects the driving end of the rotating driver 311 from the main shaft 21.

[0033] The present invention utilizes a fermenter 1, a stirring device 2, and a drive device 3 to control the on / off switching of the stirring device 2 based on temperature changes. Temperature changes during the fermentation process are used to control the on / off switching of the stirring device 2. Stirring device 2 is deactivated during the early and late stages of fermentation and automatically activated during the active fermentation phase. This prevents the adverse consequences of excessive stirring during the delayed period of microbial adaptation and the stabilization or decay phase of fermentation. This solves the problem of controlling the on / off switching of the stirring device 2 during aerobic fermentation. The fermenter 1 is equipped with a controller for human-machine interaction. The rotary drive 311 is preferably a servo motor. The temperature sensor 11 and the rotary drive 311 are both electrically connected to the controller. During the fermentation of an apple cider vinegar beverage, immediately after inoculation with acetic acid bacteria, the fermentation liquid temperature is generally close to ambient temperature, typically between 20-25°C. During the active fermentation phase, the temperature rises rapidly, reaching 30-35°C. During this phase, the growth and metabolic activity of acetic acid bacteria are at their most vigorous, with them multiplying in large numbers and continuously producing acetic acid. The increase in temperature accelerates the metabolic rate of acetic acid bacteria. Simultaneously, after sensing the temperature change, the temperature sensor 11 sends a feedback signal to the controller, which in turn sends a signal to the connecting assembly 32 and the rotary driver 311. The driving end of the rotary driver 311 is connected to the main shaft 21 via the connecting assembly 32. After the rotary driver 311 is started, it drives the main shaft 21 and the stirring frame 22 to rotate and perform stirring. As the ethanol is gradually consumed and the growth environment of the acetic acid bacteria changes, such as increased acidity and decreased nutrients, the metabolic activity of the acetic acid bacteria gradually weakens and the temperature begins to drop. The temperature gradually decreases from between 30 and 35°C to near the ambient temperature. The connecting assembly 32 disconnects the driving end of the rotary driver 311 from the main shaft 21, and the controller simultaneously shuts down the rotary driver 311. This avoids problems such as damage to microbial activity and accelerated microbial autolysis caused by excessive stirring.

[0034] Reference Figure 3-Figure 6 : A connecting block 211 is provided on the main shaft 21; the stirring frame 22 includes a first rotating shaft 221 and a stirring blade 222, the first rotating shaft 221 is rotatably set on the connecting block 211, and the stirring blade 222 is sleeved on the first rotating shaft 221; an adjusting mechanism 4 for adjusting the inclination angle of the stirring blade 222 is provided in the fermentation tank 1, and the adjusting mechanism 4 includes a temperature sensing component 41 and an adjusting component 42; the temperature sensing component 41 is provided in the fermentation tank 1, and the temperature sensing component 41 is used to sense the temperature changes in the fermentation tank 1; the adjusting component 42 is used to control the rotation of the first rotating shaft 221.

[0035] The present invention realizes the function of adjusting the inclination angle of the stirring blade 222 according to the temperature in the fermentation tank 1 through the connecting block 211, the first rotating shaft 221, the stirring blade 222, the temperature sensing component 41 and the adjusting component 42. During the fermentation process, when the temperature in the fermentation tank 1 increases, the temperature sensing component 41 drives the first rotating shaft 221 to rotate through the adjusting component 42, and the first rotating shaft 221 drives the stirring blade 222 to rotate, increasing the lateral pushing area of ​​the stirring blade 222, thereby improving the stirring efficiency. Conversely, when the temperature decreases, the adjusting mechanism 4 controls the stirring blade 222 to gradually reset, reducing the stirring efficiency. In the working state, when the temperature in the fermentation tank 1 is higher than the threshold value, the connecting component 32 connects the driving end of the rotary driver 311 and the main shaft 21, and the rotary driver 311 drives the main shaft 21 and the stirring frame 22 to rotate through the connecting component 32. During the stirring process, the metabolic rate of acetic acid bacteria will be accelerated, thereby accelerating the rate of temperature increase. As the temperature rises, the temperature sensing assembly 41 controls the rotation of the first rotating shaft 221 through the regulating assembly 42, which in turn drives the stirring blade 222 to rotate, thereby improving the stirring efficiency of the stirring blade 222. Furthermore, during the stirring process, the regulating mechanism 4 controls the angle of the stirring blade 222 in real time according to the temperature change, thereby adjusting the stirring efficiency of the stirring device 2.

[0036] Reference Figure 3 : A protective shell 23 for protecting the main shaft 21 and the adjusting mechanism 4 is sleeved on the main shaft 21, and the protective shell 23 is rotatably matched with the cover of the fermentation tank 1.

[0037] The present invention isolates the main shaft 21 and the regulating mechanism 4 by providing a protective shell 23, thereby preventing the fermented raw materials from directly contacting the main shaft 21 and the regulating mechanism 4, thereby improving the stability of the equipment operation. Fermentation raw materials often have certain corrosive, sticky or other special properties. If they come into direct contact with the driving parts, they may erode the surface of the parts, causing the main shaft 21 and the regulating mechanism 4 to rust, be damaged or become stuck, thereby affecting their normal operation. The isolation effect of the protective shell 23 greatly reduces the risk of equipment failure caused by raw material erosion, thereby improving the stability of the equipment operation. This design ensures that the entire apple cider vinegar fermentation process can be carried out continuously and efficiently, effectively reducing the time and cost waste caused by equipment maintenance or replacement of parts.

[0038] Reference Figure 2 、 Figure 7 and Figure 8: The connecting assembly 32 includes a connecting ring 321, a sleeve 322, a second rotating shaft 323 and a docking ring 324; the connecting ring 321 is transmission-connected to the driving end of the rotary driver 311; the sleeve 322 is sleeved on the main shaft 21, the second rotating shaft 323 is coaxially slidably connected with the sleeve 322, and the sleeve 322 has a built-in linear driver for driving the second rotating shaft 323 to slide; the docking ring 324 is sleeved on the second rotating shaft 323, and the axis of the connecting ring 321 is colinear with the axis of the docking ring 324. When the connecting ring 321 abuts against the docking ring 324, the connecting ring 321 will drive the docking ring 324 to rotate synchronously.

[0039] The present invention achieves the function of controlling the transmission connection between the rotary driver 311 and the main shaft 21 through the connecting ring 321, sleeve 322, second rotating shaft 323 and docking ring 324, thereby achieving the effect of controlling the opening and closing of the stirring device 2. The linear driver built into the sleeve 322 is preferably an electric push rod, and the sleeve 322 is provided with brushes to transmit power and control signals to the controller. The connecting ring 321 and the docking ring 324 can transmit power through friction, and anti-slip grooves can be provided on the contact surface of the connecting ring 321 and the docking ring 324 to increase friction. In this embodiment, the connecting ring 321 is provided with a docking post 3211 and a first elastic member 3212. The docking post 3211 is slidably mounted on the connecting ring 321. The two ends of the first elastic member 3212 are respectively connected to the connecting ring 321 and the docking post 3211. The docking ring 324 is provided with a docking groove 3241 that cooperates with the docking post 3211. In operation, when the temperature sensor 11 senses a temperature above a threshold, the controller sends a signal to the linear actuator. Upon receiving the signal, the linear actuator drives the second rotating shaft 323 toward the connecting ring 321, which in turn drives the docking ring 324. When the docking ring 324 abuts the connecting ring 321, if the docking post 3211 is misaligned with the docking slot 3241, the docking post 3211 is squeezed by the docking ring 324, causing the first elastic member 3212 to contract. As the rotary actuator 311 drives the connecting ring 321 to rotate, the connecting ring 321 drives the docking post 3211 to rotate. During the rotation of the docking post 3211, when the docking post 3211 aligns with the docking slot 3241, the elastic force of the first elastic member 3212 causes the docking post 3211 to engage with the docking slot 3241. Then, the connecting ring 321 drives the docking ring 324 to rotate synchronously, the docking ring 324 drives the second rotating shaft 323 and the sleeve 322 to rotate, and the sleeve 322 drives the main shaft 21 and the stirring frame 22 to rotate to perform stirring.

[0040] Reference Figure 4 and Figure 9: The temperature sensing component 41 includes a temperature sensing chamber 411, a piston plate 412 and a first connecting rod 413; the temperature sensing chamber 411 is connected to the main shaft 21, and the temperature sensing chamber 411 is filled with inert gas; the piston plate 412 is slidably installed in the temperature sensing chamber 411; the first connecting rod 413 is connected to the piston plate 412, and the first connecting rod 413 is transmission-connected to the adjustment component 42.

[0041] The present invention utilizes the temperature-sensing chamber 411, piston plate 412, and first connecting rod 413 to sense temperature changes within the fermentation tank 1 and, through these temperature changes, provide driving force to the adjustment assembly 42. During the stirring process, as the temperature rises, the gas within the temperature-sensing chamber 411 expands, causing the piston plate 412 to move under the action of the gas pressure. The piston plate 412 transmits the thrust to the adjustment assembly 42 via the first connecting rod 413. The adjustment assembly 42 controls the rotation of the first rotating shaft 221, which in turn drives the stirring blade 222 to rotate, thereby improving the stirring efficiency of the stirring blade 222.

[0042] Reference Figure 4 and Figure 9 : A buffer chamber 43 is provided at the top of the temperature sensing chamber 411; a top cover 431 is provided at the top of the buffer chamber 43, and a movable piece 432 is provided in the buffer chamber 43 which can be raised and lowered, and the movable piece 432 is connected to the first connecting rod 413; a second elastic member 433 is provided on the movable piece 432, and the two ends of the second elastic member 433 are respectively connected to the top cover 431 and the movable piece 432.

[0043] The present invention realizes the function of controlling the driving efficiency of the piston plate 412 and the first connecting rod 413 by the top cover 431, the movable plate 432 and the second elastic member 433. In order to enable the temperature sensing component 41 to provide sufficient air pressure driving force, the volume of the temperature sensing chamber 411 is large, and the moving stroke of the first connecting rod 413 is short, and it is only necessary to control the stirring blade 222 to rotate within 0-90 °. For this reason, a buffer chamber 43 is provided, and the second elastic member 433 is preferably a compression spring. When the temperature rises, the piston plate 412 drives the first connecting rod 413 to move up, and the first connecting rod 413 drives the movable plate 432 to move up, and the second elastic member 433 contracts under the pressure, and as the second elastic member 433 contracts, the elastic force generated by it also increases thereupon, and the resistance to the upward movement of the piston plate 412 also increases thereupon, thereby controlling the upward movement speed of the piston plate 412, avoiding a sudden increase in stirring efficiency in a short time, and stabilizing the adjustment speed of stirring efficiency.

[0044] Reference Figure 4 、 Figure 5 and Figure 10: The adjustment component 42 includes a transmission ring 421, a rack 422 and a rotating gear 423; the transmission ring 421 is connected to the first connecting rod 413; the rack 422 is connected to the transmission ring 421; the rotating gear 423 is transmission-connected to the first rotating shaft 221, and the rotating gear 423 is meshed with the rack 422.

[0045] The present invention realizes the function of controlling the rotation of the stirring blade 222 when the piston plate 412 moves by a transmission ring 421, a rack 422 and a rotating gear 423. The stirring blade 222 and the first rotating shaft 221 are provided with a plurality of them, and each first rotating shaft 221 is sleeved with a pulley 424, and a transmission belt 425 is sleeved on the pulley 424. Adjacent pulleys 424 are connected by the transmission belt 425, and the adjacent first rotating shafts 221 located on the same side are connected by the pulley 424 and the transmission belt 425. When the temperature rises, the piston plate 412 drives the first connecting rod 413 to move up, and the first connecting rod 413 drives the transmission ring 421 and the rack 422 to move, and the rack 422 is meshed with the rotating gear 423. The rack 422 drives the rotating gear 423 to rotate when it moves, and the rotating gear 423 drives the first rotating shaft 221 and the stirring blade 222 connected thereto to rotate when it rotates, thereby adjusting the angle of the stirring blade 222.

[0046] Reference Figure 4-Figure 6 : The adjusting mechanism 4 includes a transmission assembly 44, which includes a mounting plate 441, a third rotating shaft 442, a worm 443 and a worm wheel 444; the mounting plate 441 is connected to the main shaft 21, and a vertical rod 4411 is provided on the mounting plate 441; the third rotating shaft 442 is rotatably set on the vertical rod 4411, the rotating gear 423 is sleeved on the third rotating shaft 442, and the worm 443 is coaxially connected to the third rotating shaft 442; the worm wheel 444 is sleeved on the third rotating shaft 442, and the worm wheel 444 is meshed with the worm 443.

[0047] The present invention realizes the function of rotating the stirring blade 222 by rotating the rotating gear 423 through the mounting plate 441, the third rotating shaft 442, the worm 443 and the worm gear 444. In the working state, when the first connecting rod 413 moves, the first connecting rod 413 drives the transmission ring 421 and the rack 422 to move, and the rack 422 drives the rotating gear 423 to rotate when moving. The rotating gear 423 drives the third rotating shaft 442 and the worm 443 to rotate. When the worm 443 rotates, it drives the worm gear 444 engaged with it to rotate, and then drives the first rotating shaft 221 to rotate through the worm gear 444. The rotating gear 423 is sleeved on the third rotating shaft 442 located at the top end. When the third rotating shaft 442 rotates, the remaining third rotating shafts 442 are driven to rotate synchronously through the pulley 424 and the transmission belt 425. And by the arrangement of the worm gear 444 and the worm 443, it is possible to avoid the situation where the stirring blade 222 rotates by itself due to resistance during the rotation process.

[0048] Reference Figure 10 and Figure 11 : A first limiting ring 24 for limiting the moving range of the transmission ring 421 is provided on the top cover 431 of the buffer chamber 43, and a support 241 for connecting to the top cover 431 is provided at the bottom of the first limiting ring 24.

[0049] The present invention limits the moving range of the transmission ring 421 by the first limiting ring 24, thereby controlling the rotation range of the first rotating shaft 221 and the stirring blade 222. In order to ensure the effectiveness of the adjustment, it is necessary to control the stirring blade 222 to rotate within 0-90°. For this purpose, the first limiting ring 24 is set to control the lifting range of the transmission ring 421, so that the transmission ring 421 can drive the stirring blade 222 to rotate within the specified range when moving.

[0050] Reference Figure 11 : A support ring 3231 is provided on the second rotating shaft 323, and a connecting frame 26 is rotatably provided on the support ring 3231. A second limiting ring 25 that can be lifted and lowered is provided on the top cover 431. The second limiting ring 25 is provided with a second connecting rod 251, and the second connecting rod 251 is connected to the connecting frame 26.

[0051] The present invention realizes the function of controlling the movement of the transmission ring 421 through the support ring 3231, the second limiting ring 25, the second connecting rod 251 and the connecting frame 26. When the connecting assembly 32 is in the disconnected state, the second rotating shaft 323 is in the downward movement state, and the second rotating shaft 323 drives the connecting frame 26 to move through the support ring 3231. The connecting frame 26 pushes the second limiting ring 25 through the second connecting rod 251, and limits the upward movement of the transmission ring 421 through the second limiting ring 25, thereby stopping the angle adjustment of the stirring blade 222. When the connecting assembly 32 is in the connected state, the second rotating shaft 323 pulls the connecting frame 26 upward through the support ring 3231, and the connecting frame 26 drives the second limiting ring 25 upward through the second connecting rod 251, thereby releasing the upward movement restriction of the transmission ring 421, and then adjusting the angle of the stirring blade 222 through temperature changes.
