Is high carbon alcohol defoamer resistant to high temperature

Introduction: high carbon alcohol defoamer is a kind of defoamer commonly used in our life and production Then, is high carbon alcohol defoamer resistant to high temperature? What's the difference between defoamer and defoamer? A brief introduction of Baibai safety net High carbon alcohol is a strong hydrophobic and weak hydrophilic linear molecule, which is an effective defoamer in water system In the early 1970s, Soviet Union scholars experimented in the aqueous solution of anionic, cationic and non-ionic surfactants, and proposed that the defoaming effect of alcohol was related to its solubility and diffusion degree in the foaming solution C7 ~ C9 alcohol is the most effective defoamer The high alcohols of C12~C22 are made up of suitable emulsifiers, which are made up of water emulsions with a particle size of 4~9 m and 20~50% content, that is, the defoamer of water system Some esters, such as phenylethanol oleate and lauryl phenylacetate, have antifoaming effects in penicillin fermentation, and the latter can also be used as a precursor The defoamers used in food are easy to be used, some of which have defoaming effect and some of which have long-term antifoaming effect Therefore, the defoamers are divided into defoamers and antifoaming agents according to their use The defoamers commonly used in food are mainly divided into four categories: 1 Natural oil, mainly including peanut oil, corn oil, soybean oil, rice sugar oil, tea seed oil and cottonseed oil, of which peanut oil is better 2 polyether and polyether defoamers are non-ionic surfactants, so they can be spread well in foaming medium All kinds of polyether defoamers are colorless or yellow viscous liquids, which are not volatile and have good thermal stability 3 High carbon alcohols, eighteen yeasts are more commonly used, which are often used with carriers 4 Silicone defoamer and silicone defoamer are suitable for the fermentation of micro alkaline bacteria In the processing of food with poor effect on micro acid environment, it is necessary to sterilize the materials at high temperature, which requires that the silicone emulsion can withstand high temperature and break the emulsion rapidly in the foaming medium Is the high-carbon alcohol defoamer resistant to high temperature? The appearance of the high-carbon alcohol defoamer is light yellow viscous liquid with viscosity of 400-800 and water content of ≤ 1.5%; it has stable chemical properties and poor fluidity at low temperature High carbon alcohol defoamer, high temperature resistance, strong alkali resistance, but its defoaming speed and time are not ideal, need to work with the carrier What is the difference between defoamers and defoamers? Xiaobian, Bai Bai safety net, thinks that we can distinguish the difference between the two The defoamer obviously eliminates the excessive toxic foam in the production, and the defoaming agent separates the bubbles Therefore, we should distinguish the difference between powder and powder, and do not mix them up when using We all need to know more about food safety and learn to use food safety detector, so as to help us identify food safety more quickly Editor in charge: he xianrob
