Each culture area is separated to prevent material accumulation, ensure that the bacteria can fully dissipate heat and contact with oxygen, and improve the reproduction speed of the bacteria.

[0028] Embodiment 2:

[0029] Based on the above embodiments, this embodiment Figure 2 and Figure 3 As shown, the material holding assembly 4 includes a fan-shaped plate 8, a telescopic connecting rod 9 and a ring sleeve 10, the ring sleeve 10 is installed on the central axis 3, one end of the telescopic connecting rod 9 is rotatably installed on the inner wall of the culture tank 1, and multiple fan-shaped plates 8 are evenly arranged along the central axis 3 and form a circle, and one end of the fan-shaped plate 8 is connected to the other end of the telescopic connecting rod 9, and the other end of the fan-shaped plate 8 is rotatably connected to the ring sleeve 10.
