Fermentation tanks are widely used in fields such as food, beverages, pharmaceuticals, and cosmetics, among which stainless steel fermentation tanks are widely used due to their corrosion resistance, easy cleaning, and convenient operation. Fermentation is a key process in the entire production process, and the stirring stainless steel fermentation tank, as the main equipment in the fermentation process, has a significant impact on product quality and production efficiency based on the process principles involved.
The stirred stainless steel fermentation tank is mainly composed of a tank body, stirring equipment, cooling or heating equipment, feed inlet, discharge outlet, and detection instruments. The interior is usually polished to ensure a smooth surface and prevent microbial growth. Externally, mirror polishing or sanding treatment is carried out to prevent rust and enhance aesthetics, and insulation or cooling can be carried out according to specific production requirements.
During the fermentation production process, fermentation substances and culture medium are first added to the tank. Then, by controlling parameters such as heating, cooling, and ventilation, the temperature, pH value, and nutrients inside the tank are kept in an appropriate state, which is conducive to the growth and metabolism of the microbial community. The stirring equipment evenly disperses the bacterial cells through the stirring blades inside the tank, increasing the contact area between the bacterial cells and the culture medium in the limited space inside the tank, which is conducive to the growth and metabolism.
In addition to mixing equipment, the tank can also be equipped with further processing equipment such as centrifugal pulping machines or homogenizers to enhance the fermentation efficiency. During the stirring and fermentation process, it is necessary to regularly extract samples for various tests to ensure production quality and accurately grasp process parameters.
