In bio-fermentation production, excessive foam generation is a common and stubborn problem. Large amounts of foam not only reduce the effective volume of the reactor and lower production efficiency, but can also cause liquid overflow, increase the risk of contamination, and even affect the separation and purification of the final product, directly causing economic losses and quality fluctuations.
Common defoamers on the market often face challenges: some defoam quickly at first but lack durability and need to be added frequently; some have poor chemical compatibility and may inhibit strain activity or affect the product; and others perform unstably in high-temperature, high-shear, or complex fermentation systems. These pain points make stable control of the production process difficult.
Chemi Tech focuses on meeting these challenges and provides a series of high-performance fermentation defoamer solutions. Our products are carefully designed with the dual capability of rapid defoaming and long-lasting foam suppression. Their core advantage lies in good compatibility with the fermentation system: they do not negatively affect cell growth or metabolic products, and they can adapt to different pH, temperature, and agitation conditions while maintaining stable performance.
Our solution includes clear steps. First, our technical team will gain an in-depth understanding of your specific process, strain characteristics, and the causes of foam. Second, based on that analysis, we recommend the most suitable defoamer model and initial dosing plan. The third step is to assist with lab-scale and pilot-scale verification, optimizing the dosing point and dosage to ensure foam control while balancing cost-effectiveness. Finally, we provide ongoing production tracking and technical support, making fine adjustments based on actual conditions to achieve long-term stable operation.
A biotechnology company had long been troubled by foam problems in its amino acid fermentation project, resulting in a low tank-filling coefficient and occasional contamination. After adopting Chemi Tech's customized defoaming solution, and through precise fed-batch control, the effective volume utilization of the fermenter increased by about 15%, the foam level remained stable throughout the fermentation cycle, the contamination rate dropped significantly, the final product yield was genuinely improved, and production continuity was greatly enhanced.
Choosing Chemi Tech means choosing a reliable production partner. We provide not only products but also results-oriented technical services to help you overcome the foam challenge and achieve an efficient, stable, and controllable fermentation process.
