[0026] When using the device, first inject the culture solution to be mixed into the culture solution mixing tank 1 through the first delivery pipe 4, then turn on the drive motor 8, and use the drive motor 8 to drive the rotating shaft 6 to rotate, so that the rotating shaft 6 drives the stirring rod 7 to rotate synchronously, and use the stirring rod 7 to fully stir and mix the culture solution. If necessary, use the electric heater 9 to heat the culture solution to achieve a better mixing effect.

[0027] Example 2: Please refer to Figure 3-Figure 5 In order to solve the problem that traditional devices cannot eliminate bubbles on the liquid surface after stirring, this embodiment provides the following technical solutions, wherein a defoaming mechanism is provided, and bubbles above the liquid surface are punctured by the rotation of the defoaming mechanism. Specifically disclosed is: a defoaming mechanism for eliminating bubbles on the surface of the culture solution after stirring is provided inside the culture solution mixing tank 1, the defoaming mechanism comprises four groups of defoaming nails 14 distributed at equal intervals, and a foam buoyancy plate 15 is fixedly installed above the defoaming nails 14, the defoaming nails 14 are fixedly installed on the side of the connecting sleeve 11, and a through-type up and down sliding structure is formed between the connecting sleeve 11 and the rotating shaft 6, a limiting groove 12 in a groove-shaped structure is provided inside the connecting sleeve 11, and a clamping structure is formed between the limiting groove 12 and a clamping block 13 fixedly installed on the outer surface of the rotating shaft 6.
