Description

Technical Field

[0001] The utility model relates to the field of biotechnology, in particular to a composite microbial fermentation device. Background Art

[0002] Microbial fermentation is a sophisticated biotechnology that transforms raw materials into products of great value to human society through unique metabolic processes by selecting specific microorganisms in the best environment. The core of this production process lies in the intrinsic genetic properties of the strains and the carefully controlled culture environment. In particular, the application of composite microorganisms has shown great potential in the field of agricultural feed. Microbial fermentation is generally carried out in a tank. After the fermentation is completed, the material in the tank needs to be taken out. However, due to the stickiness of the material, some of the residual material will adhere to the inside of the tank, resulting in the next fermentation. The residual material of the previous fermentation will remain, resulting in poor fermentation quality. For this reason, we proposed a composite microbial fermentation device. Utility Model Content

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the utility model provides a composite microbial fermentation device, which has the following beneficial effects:

[0017] 1. The composite microbial fermentation device drives the piston rod on the cylinder to drive the cleaning ring through the connecting rod to slide on the inner wall of the fermentation tank body, and cleans the inner wall of the fermentation tank body of the residual material. The residual material may contain microorganisms in the previous fermentation process. If it is not removed in time, these microorganisms will cross-contaminate with the strains of the next fermentation, affecting the quality of the fermented product. Removing the residual material can effectively avoid this situation. In addition, the residual material attached to the inner wall of the fermentation tank occupies the space that should be used for new raw materials. Regular cleaning can ensure that there is enough space for each fermentation, so that more raw materials can participate in the fermentation, thereby increasing the yield.

[0018] 2. The composite microbial fermentation device can separate the sealing cover from the fermentation tank body by pushing the arc plate on the top of the vertical pole upward through the disc, eliminating the step of manual removal and improving the efficiency of cleaning. When the cleaning ring is cleaned, the fermentation tank body can be well sealed to prevent other substances from entering the fermentation tank body and causing contamination of the materials in the fermentation tank body.

The end of the connecting rod 7 is fixedly connected to the cleaning ring 6. The top of the cleaning ring 6 is provided with an annular annular groove 9. When it is necessary to clean the residual material remaining on the inner wall of the fermentation tank body 3, the driving cylinder 5 is first started, and the piston rod on the driving cylinder 5 is used to push upward to drive the disc 8 to move upward. The cleaning ring 6 slides upward on the inner wall of the fermentation tank body 3 through the connection between the four groups of connecting rods 7 and the disc 8.

[0029] Four groups of connecting rods 7 are arranged in a circular shape and are equidistantly distributed. One end of the connecting rod 7 is fixedly connected to the outer wall of the disc 8, and the other end of the connecting rod 7 is fixedly connected to the inner wall of the cleaning ring 6.

The cleaning ring 6 cleans the residual material remaining on the inner wall of the fermentation tank body 3 during the sliding process, and the residual material falls into the ring groove 9 through the sliding of the cleaning ring 6 for collection.

[0030] Two groups of circular holes 14 are formed in the annular groove 9. When the cleaning ring 6 slides to the top of the inner wall of the fermentation tank body 3, the two groups of straight shafts 13 are pushed upward in the cleaning ring 6, so that the two groups of straight shafts 13 slide upward in the circular holes 14 respectively.
