In the process of biopharmaceutical, the growth of some microorganisms requires a lot of oxygen, and the main purpose of filling the compressed air into the fermenter is to supply enough oxygen. At this time, the required compressed air pressure is usually between 1.0-3.0 kg, and too high compressed air pressure will affect the air exchange rate, resulting in the accumulation of carbon dioxide and insufficient oxygen, and ultimately resulting in feedback inhibition, bacterial vitality is reduced, making the fermentation incomplete or even stagnant.
The traditional way of the workshop is often to choose an air compressor with a pressure of 7.0-8.0 kg, and install a pressure reducing valve separately in the compressed air pipeline of biological fermentation. In this case, once the pressure reducing valve fails, the entire fermentation process will fail. Through many exchanges with customers, we recommend three ships for customers: first class compression screw air compressor.
