The working principle of the defoaming electrode and its role and selection in the design of biological fermentation tanks
In actual fermentation processes, due to the presence of proteins, polysaccharides, surfactants in the culture medium, and the influence of microbial metabolites, foaming is almost inevitable. Once foam is out of control, it will not only affect the effective working volume but also lead to contamination, sensor failure, material loss, and even potential safety hazards. Therefore, in the design of fermentation systems, defoaming is a key engineering issue that must be prioritized, and defoaming electrodes are one of the core detection components for achieving automated foam control.
Unveiling the "Power Heart" of Bioreactors: How Motors and Drive Systems Enable the Stirring Magic
For non-specialist readers, these components may seem complex and difficult to understand, yet they function like the "heart and blood vessels" of the equipment. They precisely transmit power and regulate the rhythm of operation, directly determining the efficiency and outcome of the biological reaction. From a popular science perspective, this article dissects the working logic, core components, and critical roles of this power system.
The working principle of pressure sensors and their role and selection in the design of bioreactors
Pressure not only affects gas solubility, oxygen transfer rate (OTR), and cell metabolic status but also directly relates to equipment safety and sterility assurance.
The working principle of DO electrodes and their role and selection in the design of biological fermentation tanks
Whether it is microbial fermentation or animal cell culture, dissolved oxygen (DO) is one of the key parameters affecting cell metabolism, product synthesis, and growth rate.
