Products Introduction：

 RA-8100 defoamer is a polyether type defoamer specially developed for foaming characteristics of fermentation industry. It has the characteristics of rapid defoaming and lasting defoaming effect, which can effectively eliminate and inhibit the foam produced in the fermentation process. The product is non-toxic and harmless, and the raw materials used are food grade. It can be widely used for foam control in microbial fermentation, food processing and other production processes.

Application：

^★Suitable for the elimination and control of foam in the biological fermentation process of citric acid, folic acid, B12, vitamin C, avermectin, lysine, penicillin,

erythromycin, flavomycin, aureomycin, xanthan gum and ethanol.

^★It is suitable for foam elimination and control of other systems in pesticide production, veterinary drug processing and late extraction process.

^★ Suitable for the elimination and control of foam produced by water treatment and other water-based systems in fermentation industry.

Characteristic：

^★Fast defoaming speed and long - lasting foam- inhibit effect

^★Good dispersion, good compatibility with water - based system.

^★High temperature resistance, 130℃ no oil bleaching, good stability

^★No biological toxicity, no effect on the growth and reproduction of microorganisms

Usage Method：

<!--[if !supportLists]-->1. <!--[endif]-->Before the disinfect, it is added to the disinfection tank together with other raw materials for disinfection

treatment to control the foam generation of the base material.

2.After fermentation to a certain stage, if antifoaming agent needs to be added, RA-8100 can be directly added to the fermenter after high temperature disinfection.

3, other non-fermentation process, according to the production process to determine the addition method of defoaming agent.
