Description

Technical Field

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

[0002] Bio-fermentation engineering is an important component of bioengineering, in which microorganisms utilize carbohydrates to ferment and produce various industrial solvents and chemical raw materials.

[0003] In the prior art, CN213596294U discloses a biotechnology sealed fermentation device, including a fermentation tank, a latch, and a top cover. The latch is fixedly installed on the top of the outer wall of the fermentation tank, and the other end of the latch is fixedly installed on the top cover. A processor is fixedly installed inside the top cover. The beneficial effects achieved by this utility model are: the utility model has a simple structure, practical function, and is easy to use. The latch and sealing strip keep the fermentation tank in a sealed environment, and it can dynamically monitor the changes in parameters inside the fermentation tank, including changes in pH value, temperature, pressure, dissolved oxygen, nutrients, and alcohol concentration. It can ensure that adverse factors occurring during the fermentation process are detected and intervened in a timely manner, making the fermentation process more perfect, reducing fermentation time, and recording fermentation parameters to provide a reference for future fermentations.

[0004] The technical solution proposed in the aforementioned patented technology, when actually carrying out biotechnology fermentation, only uses a stirring shaft and blades to stir at the bottom of the fermentation tank. This stirring fermentation method results in the materials located at the bottom and top of the fermentation tank not being able to mix quickly and evenly, which easily leads to stratification and thus seriously affects the fermentation efficiency.

[0005] In view of this, this application proposes a biotechnology sealed fermentation device. Utility Model Content

[0061] In this embodiment, by setting up a stirring and heating component 300, the materials at the bottom and top of the fermentation tank 100 can be fully and quickly mixed during the actual biological fermentation process of the biotechnology sealed fermentation device. Moreover, during the stirring process, the materials being stirred can be fully and evenly heated by several electric heating plates 306, thereby effectively improving the fermentation efficiency.

[0062] Example 2

[0063] Based on Example 1, and differing from Example 1 in that,

[0064] A temperature sensor 700 is fixedly installed on the inner wall of the fermenter 100, and the temperature sensor 700 and several electric heating plates 306 are electrically connected to the PLC controller 200 through wires.

[0065] By setting a temperature sensor 700, it is easy to monitor the temperature inside the fermenter 100 in real time.

[0066] In this embodiment, by setting a temperature sensor 700 and a PLC controller 200, the fermentation temperature can be automatically and precisely controlled during the biological fermentation process of the material, thereby further improving the fermentation efficiency.

[0067] Working Principle: In the actual biotechnology sealed fermentation process, the material is first added to the fermentation tank 100 through the feeding pipe 400, and the drive motor 307 is started. The rotation of the drive motor 307 drives the rotating shaft 309 to rotate, which in turn drives the active gear disc 3010 to rotate. The rotation of the active gear disc 3010 drives the driven gear disc 3011 and the rotating tube 301 to rotate. The rotation of the rotating tube 301 drives the two scrapers 304 to rotate simultaneously, and the material inside the fermentation tank 100 is stirred by the two sets of stirring blades 305. At the same time, the rotation of the rotating shaft 309 also drives the first transmission wheel 3012 to rotate. The rotation of the first transmission wheel 3012 drives the second transmission wheel 3013 and the rotating rod 302 to rotate through the transmission belt 3014. The rotation of the rotating rod 302 drives the spiral conveyor blade 303 to rotate upward, thereby conveying the material from the bottom of the fermentation tank 100 to the top of the fermentation tank 100. Under the action of the stirring blades 305, the material is stirred and fermented. The materials at the bottom and top of the fermentation tank 100 can be thoroughly and quickly mixed. During the mixing process, several electric heating plates 306 provide thorough and uniform heating, effectively improving fermentation efficiency. Furthermore, during the biological fermentation process, the temperature inside the fermentation tank 100 is monitored by a temperature sensor 700. When the temperature inside the fermentation tank 100 reaches the value preset by the temperature sensor 700 via the PLC controller 200, the temperature sensor 700 transmits a signal to the PLC controller 200, which automatically shuts off the electric heating plates 306. When the temperature inside the fermentation tank 100 falls below this value, the temperature sensor 700 transmits a signal to the PLC controller 200, which automatically activates the electric heating plates 306. This allows the fermentation device to achieve precise automatic temperature control, further improving fermentation efficiency.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
