AI Technical Summary
Traditional culture medium filling machines struggle to achieve thorough and uniform mixing during the mixing and stirring process, and lack efficient heat dissipation structures, leading to unstable culture medium quality and changes in composition.
The device employs a stirring assembly and a water-cooled structure design. A drive motor drives the stirring rod to mix the culture medium raw materials, and a water pump and a ring-shaped water spray pipe form a cooling water circulation to absorb the heat generated by stirring, ensuring uniform mixing and effective heat dissipation.
This method achieves thorough and uniform mixing and effective cooling of the culture medium, thereby improving the quality stability and filling accuracy of the culture medium.
