In the field of industrial fermentation, the generation of foam is a common but thorny problem. From food processing to pharmaceuticals, from chemical production to biotechnology industry, the appearance of foam in the fermentation process is inseparable, which brings many negative impacts to production. The birth of industrial fermentation defoamer has become a key factor in ensuring the smooth progress of industrial fermentation.

The existence of foam has many hazards to industrial fermentation. First, too much foam will occupy a lot of space in the fermentation tank, limit the amount of fermentation liquid, and reduce the utilization rate of fermentation equipment. Secondly, foam may cause liquid escape during the fermentation process, causing loss of fermentation liquid, increasing production costs, and may also pollute the production environment.

Industrial fermentation defoamer can effectively eliminate foam, and its working principle is mainly based on two aspects: foam breaking and foam suppression. Foam breaking means that the defoamer can quickly destroy the foam that has been formed, causing it to break and disappear. Defoamers usually have low surface tension. When they come into contact with the foam surface, they can quickly spread and replace the liquid film on the foam surface, thereby destroying the stability of the foam.

In the pharmaceutical industry, the fermentation production of antibiotics has high requirements for the environment and product quality. The foam generated during the fermentation process may introduce impurities, affecting the purity and efficacy of the antibiotics. Polyether defoamers are widely used in antibiotic fermentation processes due to their good water solubility and antifoaming properties.

With the continuous development and innovation of industrial fermentation technology, higher requirements are also placed on the performance of industrial fermentation defoamers. In the future, industrial fermentation defoamers will develop in a more efficient, environmentally friendly and safe direction. R&D personnel will focus on developing new defoamer formulas to improve the defoaming efficiency and antifoaming durability of defoamers, while reducing their impact on the environment.
