What principles are used in the design of stainless steel fermenters?

The fermentation cooling jacket, which completely wraps around the fermenter, provides the most direct cooling contact. The mechanical stirring of the materials in the fermenter creates axial and radial movement, resulting in excellent mixing of the materials within the tank and keeping solid substances suspended in the liquid. This facilitates full contact between solids and nutrients, aiding nutrient absorption. On the other hand, it breaks up bubbles, increasing the gas-liquid contact area and improving the transfer rate between gas and liquid.

Because the rotor's space in the stainless steel fermenter is open to the atmosphere, the air outside the fermenter is continuously drawn in through a filter, quickly flung towards the outer edge of the impeller, and then evenly distributed by the anisotropic impeller to create a thorough mixing of gas and liquid. This creates an intense mixing flow around the impeller, breaking up air bubbles and ensuring thorough gas-liquid mixing.

The fermentation cooling jacket completely surrounding the fermenter provides the most direct cooling contact. The mechanical agitation of the material within the fermenter creates axial and radial movement, resulting in excellent mixing of the material inside the tank. This keeps solid substances suspended in the liquid, facilitating thorough contact between solids and nutrients for better nutrient absorption. Simultaneously, it breaks up bubbles, increasing the gas-liquid contact area and improving the transfer rate between gas and liquid.

The insulated magnetic flux jacket from our company's chiller unit has multiple coolant channels evenly distributed around the fermentation chamber. This temperature control range eliminates hot and cold spots, maintaining optimal yeast conditions and fermentation. The air-cooled chiller is easy to install, requiring no opening of the fermentation vessel. It can adapt flexibly to various vessel shapes and sizes, improving oxygen transfer, eliminating bubbles, and ensuring the supply of sterile air to maintain oxygen levels for the microorganisms. This satisfies the growth and fermentation needs of aerobic bacteria. The fermenter's structure utilizes the rapid rotation of the rotor immersed in the fermentation broth. Due to centrifugal force, the liquid and air move towards the outer edge, and the pressure near the rotor gradually increases, thus increasing the rotational speed of the fermenter rotor.
