In the development process of defoamers, there are more and more types of defoamers, which are more and more perfect, and the industry is more targeted. There are many types of defoamers, which can be divided into silicone defoamers, polyether defoamers, mineral oil defoamers, etc. Polyether defoamers can be used in many industries, such as water treatment industry (such as sewage treatment, wastewater treatment, circulating water, biological water treatment, etc.), daily chemical products industry (such as detergent, laundry detergent, glass water, etc.), food fermentation and metalworking fluid industry. On December 5th, the owner of a fermentation plant contacted Ms. Chen to inquire about the application of fermented foamPolyether defoamer

In fermentation plants, too much foam can have a number of adverse effects. First of all, too much foam can lead to a reduction in the filling factor of the fermenter, which affects the fermentation efficiency. Secondly, a large amount of liquid escape can lead to product loss, which can adversely affect production. In addition, foam rises to the top of the tank and oozes out of the shaft seal, which can pose a risk of contamination. The presence of foam may also affect the respiration of the bacteria, causing metabolic abnormalities or autolysis of the bacteria.
Ms. Chen connected with the owner of the fermentation plant to understand the causes of fermentation foam. The foam in the fermentation plant is mainly caused by aeration and stirring, and during the stirring process, a large amount of air enters and foam is formed. There are many nutrients in the fermentation broth and culture medium, and it is difficult to stir and mix in the early stage, so it is easy to cause foaming problems during the fermentation process. In addition, the fermentation process uses the metabolism of microorganisms to produce the necessary substances, so the growth process of microorganisms also causes the formation of foam.
Due toPolyether defoamerIt is used in a wide range of industries, and it has remarkable results and can solve the foam problem in many industries, and the same is true for the fermentation industry. Miss Chen introduced him to the polyether defoamer, which is mainly a defoamer prepared by polymerization of propylene glycol or glycerin, propylene oxide, ethylene oxide, etc., catalyzed by potassium hydroxide. It is characterized by fast defoaming, strong stability, no color spots and other advantages, which is suitable for most defoaming industries as the needs of defoaming and foam suppression.
