Which industries are ultrasonic defoaming used in?

Ultrasonic defoaming has been widely used in many industrial production fields due to its high efficiency and environmental protection. The details are as follows:

1. **Food processing industry**: During the production process of juice, beer, beverages, etc., a large amount of foam is easily generated. For example, in the juice concentration process, ultrasonic defoaming can effectively eliminate foam caused by material characteristics and process operations, ensuring the smooth progress of the concentration process and avoiding material loss and equipment contamination caused by foam overflow. In beer brewing, a large amount of foam will be produced during the fermentation stage. Ultrasonic defoaming can control the amount of foam and ensure the normal fermentation process without affecting the quality and taste of the beer.

2. **Chemical Industry**: In the production of chemical products such as coatings, adhesives, and inks, foam often occurs due to stirring, adding surfactants, etc. The use of ultrasonic defoaming can improve the quality and stability of products and avoid problems such as product surface defects and performance degradation caused by the presence of foam. For example, in paint production, foam will affect the leveling and glossiness of the paint. Ultrasonic defoaming can make paint production smoother and product quality more guaranteed.

3. **Biopharmaceutical industry**: During the biological fermentation process, the metabolic activity of microorganisms will produce a large amount of foam. Excessive foam will not only occupy space in the fermentation tank and affect fermentation efficiency, but may also increase the risk of bacterial contamination. Ultrasonic defoaming can effectively eliminate foam and maintain the stability of the fermentation process without affecting the growth and metabolism of microorganisms. In addition, in the production of pharmaceutical preparations, such as injections, oral liquids, etc., ultrasonic defoaming can also be used to remove foam generated during the production process to ensure product quality and safety.

4. **Sewage treatment industry**: In the sewage treatment process, the activated sludge method is a commonly used treatment method. However, a large amount of foam will be generated during the aeration process. These foams not only affect the treatment effect, but may also cause pollution to the surrounding environment. Ultrasonic defoaming can eliminate foam promptly and effectively, improve the operating efficiency of the sewage treatment system, and reduce the impact of foam on the environment.

5. **Papermaking Industry**: During the papermaking process, pulping, papermaking and other processes will produce foam. For example, in the pulping process, due to the addition of various chemicals, a large amount of foam is easily generated, which affects the quality of the slurry and the subsequent papermaking process. Ultrasonic defoaming can quickly eliminate foam, ensure the continuity of the papermaking process and the quality of the paper, and reduce paper holes, paper breaks and other defects caused by foam problems.

6. **Petroleum Extraction and Processing Industry**: During the oil extraction process, especially during the dehydration and degassing of crude oil, a large amount of foam will be generated. Ultrasonic defoaming can help improve the separation efficiency of crude oil, reduce the water and gas content in crude oil, and improve the quality of crude oil. In the petroleum refining process, foam generated in processes such as distillation and cracking can also be eliminated through ultrasonic defoaming technology to ensure the safety and stability of the production process.
