Description

Technical Field

[0001] This utility model relates to the field of fermentation tank equipment technology, and in particular to a layered controllable atmosphere modified fermentation tank equipment. Background Technology

[0002] In fermentation production in the food and biological fields, different microbial strains often require specific gaseous environments (such as different ratios of oxygen, nitrogen, and carbon dioxide) and fermentation conditions to achieve good growth and metabolism, in order to produce products with complex flavors and excellent quality. The use of layered controllable atmosphere fermentation tanks can create suitable controlled atmosphere environments for different microbial strains in a single tank, meeting the needs of simultaneous fermentation of multiple microbial strains. This not only saves on equipment investment costs, but also enhances the flavor complexity and nutritional richness of fermentation products through the synergistic effect of multiple microbial strains, which is of great significance for improving production efficiency and product quality.

[0003] In existing technologies, fermenters typically utilize the structural space of the tank itself to stir the materials inside the tank using a simple stirring device, ensuring uniform mixing. At the same time, an external gas supply system is used to introduce the required gas into the tank to regulate the overall gas environment inside the tank, so as to meet the fermentation needs of a single strain or strains with similar gas environment requirements.

[0004] However, in actual multi-strain fermentation processes, due to the significant differences in the gas composition requirements of different strains, the single internal space of existing fermentation tanks cannot simultaneously provide suitable modified atmosphere conditions for multiple strains. This results in some strains experiencing growth and metabolism inhibition due to unsuitable gas environments during fermentation in the same tank, making it difficult for them to fully exert their aroma and metabolite production capabilities. Ultimately, this leads to insufficient flavor complexity in the fermentation products, failing to achieve the ideal synergistic fermentation effect of multiple strains. To address this issue, a layered controllable modified atmosphere fermentation tank device is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a layered controllable modified atmosphere fermenter device, which aims to improve the problem that different strains of bacteria have significantly different requirements for gas composition, and that the single internal space of existing fermenters cannot simultaneously provide suitable modified atmosphere conditions for multiple strains.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A layered controllable atmosphere fermentation tank device includes a tank body, a motor fixedly connected to the top of the tank body, a rotating rod fixedly connected to the output end of the motor, a plurality of connecting sleeves fixedly connected to the outer wall of the rotating rod, a limit ring fixedly connected to the outer wall of each of the plurality of connecting sleeves, a layering component provided on the outer wall of each of the plurality of connecting sleeves, and a stirring component provided on the outer wall of each of the plurality of connecting sleeves. The layered assembly includes multiple sealing partitions, which are rotatably connected to the outer walls of multiple connecting sleeves. The multiple sealing partitions are respectively disposed between multiple limiting rings. A breathable partition is fixedly connected to the top of each of the multiple sealing partitions. A pin is slidably connected inside each of the multiple connecting sleeves. A spring is sleeved on the outer wall of the pin. The two ends of the spring are respectively connected to the connecting sleeve and the pin. Multiple insertion holes are opened inside the rotating rod, and the pin is slidably connected inside the corresponding insertion hole.

[0007] As a further description of the above technical solution: The stirring assembly includes a crushing blade and a stirring blade. One side of the crushing blade is fixedly connected to the outer wall of the connecting sleeve, and one side of the stirring blade is fixedly connected to the outer wall of the connecting sleeve.

[0008] As a further description of the above technical solution: A vent pipe is fixedly connected inside the tank, and a connecting plate is fixedly connected to the outer wall of the vent pipe.

[0009] As a further description of the above technical solution: The connecting plate is rotatably connected to a support shaft inside, and a support plate is fixedly connected to the outer wall of the support shaft.

[0010] As a further description of the above technical solution: A sealing cover is fixedly connected to one side of the support plate, and a sealing joint is provided at one end of the sealing cover, and a gas regulator is provided at one end of the sealing joint.

[0011] As a further description of the above technical solution: A fixed frame is fixedly connected to the outer wall of the vent pipe, and a rotating shaft is rotatably connected inside the fixed frame.

[0012] As a further description of the above technical solution: A threaded post is fixedly connected to the outer wall of the rotating shaft, a locking block is threadedly connected to the outer wall of the threaded post, and a knob is fixedly connected to one end of the threaded post.

[0013] As a further description of the above technical solution: The sealing cover has a slot inside, and one side of the locking block engages with the slot.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by pulling the pin to stretch the spring, after the sliding sealing partition is adjusted in position, the spring rebounds and drives the pin to insert into the insertion hole to fix the sealing partition. Multiple sealing partitions, together with the venting partition, divide the inside of the tank into multiple independent air chambers. At the same time, the motor drives the rotating rod to rotate, so that the crushing blade and the stirring blade crush and stir the material. This achieves the effect of forming multiple independent air chambers in a single tank and uniformly mixing the material in each air chamber. It solves the problem that different strains have significantly different requirements for gas composition, and the existing fermenters with a single tank space cannot provide suitable controlled atmosphere conditions for multiple strains at the same time.

[0015] 2. In this utility model, rotating the knob drives the rotating shaft and threaded column to rotate, causing the locking block to separate or engage with the sealing cover groove, thereby opening and fixing the sealing cover. The gas regulator is connected to the sealing cover through a sealing joint, allowing each independent gas chamber to be independently connected to the gas regulation system. This achieves the effect of conveniently taking out and putting in the fermentation material in the tank and adjusting the gas environment of each independent gas chamber. It solves the problems of inconvenient taking out and putting in the fermentation material and inaccurate gas regulation in each fermentation area, which makes it difficult to meet the gas regulation requirements of different strains.

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.

[0019] Reference Figures 1-4 This utility model provides an embodiment of a layered controllable atmosphere fermentation tank device, including a tank body 1. The tank body 1 is made of stainless steel with a thickness of 5-8mm, which has good corrosion resistance and sealing performance, and can provide a stable environment for fermentation. A motor 2 is fixedly connected to the top of the tank body 1. The motor 2 is a servo motor with a power of 1.5-2.5kW and adjustable speed, which is existing technology and will not be described in detail here. A rotating rod 3 is fixedly connected to the output end of the motor 2. Multiple connecting sleeves 6 are fixedly connected to the outer wall of the rotating rod 3. Limiting rings 7 are fixedly connected to the outer wall of each of the multiple connecting sleeves 6. Layering components are provided on the outer wall of each of the multiple connecting sleeves 6. The layering components can divide the interior of the tank body 1 into multiple independent air chambers to meet the atmosphere control requirements of different strains. A stirring component is provided on the outer wall of each of the multiple connecting sleeves 6. The stirring component can stir and crush the materials in each air chamber to ensure uniform mixing of materials and promote the fermentation process. The layered assembly includes multiple sealing partitions 4, which are rotatably connected to the outer walls of multiple connecting sleeves 6. The multiple sealing partitions 4 are respectively positioned between multiple limiting rings 7, which axially limit the sealing partitions 4. Each of the multiple sealing partitions 4 has a fixedly connected breathable partition 5 at its top. The breathable partition 5 is made of microporous ceramic material with a pore diameter of 10-20 μm, ensuring proper gas exchange and regulation between independent gas chambers while preventing material movement, thus achieving gas permeability under gas chamber isolation. Each of the multiple connecting sleeves 6 has a slidingly connected pin 11, with a spring 12 fitted on the outer wall of the pin 11. The two ends of the spring 12 are connected to the connecting sleeve 6 and the pin 11, respectively. The rotating rod 3 has multiple insertion holes 10 inside, with the pin 11 slidably connected to the corresponding insertion holes 10. Inside the 0, the pin 11 slides and connects to the corresponding insertion hole 10 under the elastic force of the spring 12, thereby fixing the position of the sealing partition 4 and ensuring the stability of each air chamber after stratification. The stirring assembly includes a crushing blade 8 and a stirring blade 9. One side of the crushing blade 8 is fixedly connected to the outer wall of the connecting sleeve 6. The crushing blade 8 is made of stainless steel and the other side is welded to the outer wall of the connecting sleeve 6. Under the action of the connecting sleeve 6, it can crush the fermentation material, making the material particles smaller, increasing the contact area between the material and the bacteria and gas, and promoting the fermentation reaction. One side of the stirring blade 9 is fixedly connected to the outer wall of the connecting sleeve 6. The stirring blade 9 is made of stainless steel and the other side is welded to the outer wall of the connecting sleeve 6. It can fully stir the material, so that the material is evenly mixed in its own independent air chamber, ensuring the uniformity of fermentation.

[0020] Reference Figure 1 , Figure 5 and Figure 6A vent pipe 13 is fixedly connected inside the tank body 1. The vent pipe 13 is made of seamless stainless steel pipe with a diameter of 20-30mm and is used to supply regulating gas to each independent gas chamber. A connecting plate 14 is fixedly connected to the outer wall of the vent pipe 13. A support shaft 15 is rotatably connected inside the connecting plate 14. A support plate 16 is fixedly connected to the outer wall of the support shaft 15. A sealing cover 17 is fixedly connected to one side of the support plate 16. The support shaft 15 provides rotational support for the support plate 16 and the sealing cover 17. The sealing cover 17 is made of stainless steel and fits with the opening of the tank body 1 to seal and prevent gas leakage and the entry of bacteria during fermentation. A sealing joint 18 is provided at one end of the sealing cover 17. The sealing joint 18 adopts the existing pneumatic diaphragm sealing interface. This pneumatic diaphragm sealing interface relies on the elastic deformation of the diaphragm to achieve a seal. It can fit tightly under air pressure and effectively prevent gas leakage. This is existing technology and will not be described in detail here. A gas supply is provided at one end of the sealing joint 18. The regulator 19 uses an existing multi-channel gas ratio regulator, which can precisely control the input ratio of various gases (such as O2, N2, CO2, etc.) and flexibly adjust the gas composition of each independent gas chamber according to the gas composition requirements of different strains. This is existing technology and will not be described in detail here. A fixed frame 20 is fixedly connected to the outer wall of the vent pipe 13. A rotating shaft 21 is rotatably connected inside the fixed frame 20. A threaded column 22 is fixedly connected to the outer wall of the rotating shaft 21. A locking block 23 is threadedly connected to the outer wall of the threaded column 22. A knob 25 is fixedly connected to one end of the threaded column 22. The surface of the knob 25 is provided with anti-slip texture to facilitate the operator's rotation. A locking groove 24 is opened inside the sealing cover 17. One side of the locking block 23 engages with the locking groove 24. By rotating the knob 25, the rotating shaft 21 and the threaded column 22 are rotated, so that the locking block 23 engages or disengages from the locking groove 24, realizing the opening and closing of the sealing cover 17, which facilitates the operation of taking out and putting in the fermentation material in the tank 1.

[0021] Working principle: When using this layered controlled atmosphere fermenter device, firstly, layers are set according to fermentation requirements. By pulling the pin 11, the spring 12 sleeved on the outer wall of the pin 11 is stretched, causing the pin 11 to slide out of the insertion hole 10 inside the rotating rod 3. Then, the sealing partition 4 is slid, allowing it to slide on the outer wall of the rotating rod 3. After adjusting the position and spacing of the sealing partition 4, the pin 11 is released. The spring 12 rebounds, causing the pin 11 to slide into the corresponding insertion hole 10, thereby fixing the sealing partition 4. Multiple sealing partitions 4 are arranged in a series of layers. The top permeable baffle 5 divides the interior of the tank 1 into multiple independent air chambers. During fermentation, the motor 2 on the top of the tank 1 can be started. The output of the motor 2 drives the rotating rod 3 to rotate. The rotating rod 3 drives the crushing blade 8 and stirring blade 9 on the outer wall to rotate. The crushing blade 8 crushes the fermentation material, and the stirring blade 9 stirs the material, so that the material is evenly mixed in its own independent air chamber. At the same time, the permeable baffle 5 ensures the permeability of the gas, which helps the fermentation process to proceed smoothly, realizes the simultaneous fermentation of multiple strains in a single tank, and improves the complexity of the flavor. When fermentation materials need to be removed or placed, the knob 25 at one end of the rotating shaft 21 inside the fixed frame 20 is turned. The rotating shaft 21 drives the threaded column 22 on the outer wall to rotate, causing the locking block 23 connected to the threaded column 22 to move. This causes one side of the locking block 23 to separate from the locking groove 24 inside the sealing cover 17. Then, the sealing cover 17 can be opened to remove or place the fermentation materials in the tank 1. After the removal or placement is completed, the knob 25 is turned in the opposite direction to allow the locking block 23 to re-engage into the locking groove 24, fixing the sealing cover 17. Then, the gas regulator 19 is connected to the sealing cover 17 through the sealing connector 18, so that each independent gas chamber is independently connected to the gas regulation system through the vent pipe 13 to meet different gas regulation needs.
