Technical Field
[0001] This utility model relates to the field of Bacillus subtilis production technology, specifically to a Bacillus subtilis fermentation culture device with an antifoaming structure. Background Technology
[0002] During its growth, Bacillus subtilis produces active substances such as subtilisin, polymyxin, nystatin, and bacitracin. These active substances have a significant inhibitory effect on pathogenic bacteria or opportunistic pathogens causing endogenous infections. At the same time, Bacillus subtilis also releases some active substances that are beneficial to plant growth, stimulating plant growth. Therefore, it is widely used not only in feed.
[0003] The Bacillus subtilis fermentation culture device with defoaming structure disclosed in CN218202798U improves the culture quality of Bacillus subtilis by using a temperature control device with a semiconductor refrigeration chip to cool or heat as needed, and the defoaming device can break up the foam generated on the surface of the culture medium, thereby enabling Bacillus subtilis to ferment and culture better.
[0004] This Bacillus subtilis fermentation culture device with defoaming structure can stir the Bacillus subtilis material through the set stirring blades. However, the stirring height of the stirring blades on this device cannot be adjusted, which results in the upper and lower layers of materials in the fermentation tank not being fully mixed. Therefore, it needs to be improved. Utility Model Content

[0009] Preferably, there are two slide bars, which are fixedly connected to the left and right sides of the top of the threaded plate, and are slidably connected to the inner side of the arc-shaped plate. The slide bars can limit the movement of the threaded plate, making the threaded plate more stable during the lifting and lowering process.
[0010] Preferably, the inner side of the load-bearing plate is provided with a groove corresponding to the movement trajectory of the support member, and the support member is slidably connected inside the groove. Through the groove, the support member can slide inside the load-bearing plate. The support member can support the rotating gear, making the rotating gear more stable during rotation.
[0011] Preferably, the cleaning assembly includes a water tank, which is fixedly connected to the top back of the mounting base. A telescopic pipe extends through the inner side of the water tank, and a water pump is fixedly connected to the outer side of the telescopic pipe.

[0015] Compared with the prior art, this utility model provides a Bacillus subtilis fermentation culture device with an antifoaming structure, which has the following beneficial effects:
[0016] 1. The Bacillus subtilis fermentation culture device with defoaming structure has a stirring component driven by a drive motor to rotate a threaded rod, which causes the threaded plate to slide up and down along a limit rod, thereby driving the stirring structure on the load-bearing plate to rise and fall. The rotating motor drives the rotating shaft and the drive gear to drive the rotating gear, which makes the rotating rod and stirring plate rotate at high speed, forming a strong stirring effect. This can effectively improve the uniformity of mixing nutrients and bacteria, accelerate the fermentation process, and improve fermentation efficiency.
[0017] The cleaning assembly combines a water tank, water pump, telescopic pipe, and stirring structure. The water pump draws cleaning solution from the water tank and sprays it out from the water inlet of the stirring plate and stirring rod through the telescopic pipe, rotary joint, and connecting pipe. This achieves comprehensive and thorough cleaning of the inside of the fermentation tank, preventing residual fermentation solution from breeding bacteria, reducing the workload and difficulty of manual cleaning, improving the cleaning efficiency and hygiene of the device, and providing a good environment for the next fermentation.

The cylinder extension and retraction are controlled via a PLC control panel, allowing for precise adjustment of the defoaming plate's height within the fermentation tank. When foam is generated during fermentation, the cylinders push the defoaming plate downwards, utilizing its structural characteristics to quickly break down the foam and prevent it from overflowing and affecting the fermentation process or causing material waste.

[0039] Example 3
[0040] Please see Figure 1-6 Furthermore, based on Embodiment 1, the defoaming mechanism 3 includes a cylinder 32, which is fixedly connected to the top of the fermentation tank 5. A defoaming plate 31 is fixedly connected to the bottom of the cylinder 32. The defoaming plate 31 is slidably connected to the periphery of the rotating rod 2195 and slidably connected to the inside of the fermentation tank 5.
[0041] Furthermore, there are two cylinders 32, which are fixedly connected to the left and right sides of the top of the fermentation tank 5 respectively. The cylinders 32 can drive the defoaming plate 31 to move downward, so that the defoaming plate 31 can eliminate the bubbles generated during the fermentation of Bacillus subtilis.
[0042] In actual operation, when this device is in use, the material is poured into the fermentation tank 5 through the water inlet pipe. When it is necessary to stir and ferment the material inside the fermentation tank 5, the rotating motor 2191 is turned on through the PLC control panel 4. The rotating motor 2191 drives the drive gear 218 to rotate through the rotating shaft 2192. The drive gear 218 drives the rotating rod 2195 and the stirring plate 2196 to rotate through the rotating gear 2193. This allows the stirring plate 2196 to stir the spores inside the fermentation tank 5. The bacterial material is stirred, and the drive motor 217 is turned on, so that the drive motor 217 is driven to rotate through the threaded rod 215. The threaded rod 215 drives the slide bar 214 and the load-bearing plate 216 to move upward through the threaded plate 212. The load-bearing plate 216 drives the rotating gear 2193 to rotate through the support member 2194. The rotating gear 2193 drives the stirring plate 2196 to move upward through the rotating rod 2195, so that the stirring plate 2196 can stir and ferment the Bacillus subtilis material at different heights inside the fermentation tank 5.
[0043] When Bacillus subtilis is stirred and fermented, bubbles are generated and float on the top of the material. The cylinder 32 is opened through the PLC control panel 4, which causes the cylinder 32 to move the defoaming plate 31 downward, so that the defoaming plate 31 can eliminate the bubbles.
[0044] When the Bacillus subtilis fermentation is complete and the contents are discharged, and cleaning is required, the water pump 222 is turned on via the PLC control panel 4. The water pump 222 transmits clean water from the water tank 221 to the rotary joint 224 via the telescopic pipe 223. The clean water is then transmitted to the connecting pipe 225 via the rotary joint 224, and sprayed out through the rotating rod 2195 and the stirring plate 2196, allowing the clean water to clean the inside of the fermentation tank 5. The drive motor 217 is turned on via the PLC control panel 4, causing the drive motor 217 to drive the threaded plate 212 upward via the threaded rod 215. The threaded plate 212 then drives the load-bearing plate 216 and the rotating rod 2195 upward via the slide bar 214, allowing the clean water to be sprayed to different locations inside the fermentation tank 5 for cleaning. The PLC control panel 4 model is Siemens S7-1200.
