In the mechanical stirring fermenter, the main function of the agitator is to mix and stir the materials in the fermentation tank to promote the growth and metabolism of microorganisms during the fermentation process, so as to achieve an efficient fermentation process. Specifically, the stirring effect of the agitator includes the following aspects:
Facilitates oxygen transfer: During fermentation, microorganisms need oxygen for respiration and growth. The agitator facilitates the transfer and dissolution of oxygen by mixing air well into the material inside the fermenter, thus providing the oxygen needed for microbial growth.
Maintain a uniform temperature: During fermentation, the uniformity of temperature has an important impact on the growth of microorganisms and the efficiency of fermentation. The agitator can mix and stir the materials in the fermenter to make the temperature distribution more homogeneous and avoid the adverse effects of high or low local temperature on microbial growth.
Maintain pH uniformity: During fermentation, pH uniformity is also critical for microbial growth and metabolism. The agitator can mix the fermentation liquid in the fermenter thoroughly, maintaining the uniformity of the pH value, thus promoting the growth of microorganisms and the efficiency of fermentation.
Promote homogeneous mixing of materials: In fermenters, there are often multiple ingredients and media that need to be mixed. The agitator ensures the homogeneity of the material in the fermenter by mixing and blending these raw materials, thereby improving the fermentation efficiency and product quality.
In summary, the agitator in the mechanical stirring fermenter plays a vital role in the fermentation process by promoting oxygen transfer, maintaining the uniformity of temperature and pH value, and promoting the uniform mixing of materials, ensuring the efficient progress of the fermentation process and the stability of product quality.
