Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a reactor for microbial culture, which is convenient for adding nutrient solution. Background Art

[0002] The nutrient solution reactor is a special equipment used for microbial culture and fermentation process. Microbial culture usually involves the process of microorganisms (such as bacteria, yeast, fungi, etc.) growing and reproducing in a liquid culture medium containing specific nutrients. This process is often used in the production of biological products, fermented foods, biological drugs and other fields. The core of the nutrient solution reactor is the culture medium, which is a special liquid that contains the nutrients required for the growth and reproduction of microorganisms.

[0003] At present, most of the nutrient solution reactors on the market add chemicals manually, which is not only time-consuming and labor-intensive, but also difficult to control the dosage of manually added chemicals, and long-term opening of the lid when adding chemicals can easily lead to the deterioration of microorganisms.

[0004] In the patent document with publication number CN214233957U, a feed port is set, which is not convenient for adding medicines of different properties. The solid feed port on the cover plate is convenient for adding block medicines, effectively preventing large-volume solid medicines from blocking the feed port; the liquid feed port on the cover plate is set as a funnel-shaped structure, which is convenient for adding liquid medicines and effectively preventing dripping when liquid medicines are filled; the cover plate and the annular connecting plate on the kettle body are detachably fixedly connected through mounting holes and locking bolt assemblies, which is convenient for cleaning the kettle body after the reaction.

[0005] In view of the above patent documents and background, the nutrient solution needs to be added manually for processing, which wastes manpower and material resources, and the inner wall of the reactor is not cleaned for a long time, which will cause the nutrient solution inside the reactor to change qualitatively. Therefore, a reactor that is easy to add nutrient solution and stir and clean is proposed. Utility Model Content
