[0002] Microorganisms are a general term for a class of organisms, including bacteria, viruses, fungi, actinomycetes, rickettsia, mycoplasma, chlamydia and spirochetes. These microorganisms are widely distributed in nature. Most individuals can only be seen with a microscope, and a few can be seen with the naked eye, such as mushrooms and other fungi. ‌Dust-free culture‌ refers to a series of measures taken during the culture process to ensure that the concentration of airborne particles in the culture environment is controlled within a certain range, thereby reducing the impact of microorganisms and other harmful substances on the culture. This culture method is widely used in the fields of cell culture and microbial culture to ensure the purity and survival rate of the culture.

[0020] Specifically, a guide ring is provided on the rotating wheel 7, and the outer wall edge of the guide ring itself is actually provided with a rotating groove extending inwardly toward the rotating wheel 7, so that the guide ring not only gives the rotating wheel 7 corresponding supporting force, but also can ensure the free rotation of the rotating wheel 7. At the same time, the rotating wheel 7 serves as a connecting medium between the first conveyor belt 8 and the second conveyor belt 9, and can transmit power to the first rotating tooth 10, and drive the support plate 14 to rotate in the opposite direction, so as to fully mix the nutrients and microorganisms.

[0021] A mixing adjustment mechanism 2 is provided. After the motor 3 is started, it can drive the stirring rod 6 to rotate through the rotating shaft 5. At the same time, under the action of mechanical transmission, the first rotating tooth 10 is rotated. Under the action of gear meshing transmission, the second rotating tooth 13 can be driven to rotate in the opposite direction, and then the second movable shaft 12 drives the supporting disk 14 to rotate in the same direction.
