Do you know what are the common sterilization and cleaning methods for beer equipment?
In summer, most people will like to drink beer, beer is the entrance of the drink, so you need to pay special attention to the sterilization of beer equipment is safe, in the cleaning process to be careful. As we all know, what kind of sterilization and cleaning method is adopted in the brewing of this equipment, which has an important influence on beer fermentation. Do you know how to sterilize and clean it? Is there any way? Shandong trano to introduce common sterilization and cleaning methods are divided into the following types. 1, ultraviolet sterilization ultraviolet sterilization effect on water is very useful, its activity depends on pH, temperature, is widely used in the preparation of sterile water system. Benefits: no residual taste and gas, low toxicity. Defects: poor permeability, sterilization effect depends on the turbidity of water, and no residual activity, easy to cause bacteria to grow again. 2, beer equipment formaldehyde sterilization the sterilization effect of formaldehyde is that it has a reduction effect, can inhibit bacteria or sterilization, and can combine with the amino group of protein to denature protein, thus destroying the cytoplasm of thallus. After washing clean breeding tanks and fermentation tanks with NaOH solution, formaldehyde solution with mass fraction of 2% should be selected to seal for 2 h, and then washed with clear water for later use. Benefits: soluble in water and ethanol, formaldehyde is easy to combine with the amino group in the protein, so that the protein is condensed, the gelatin is condensed, and the arrangement is fixed. Formaldehyde can preserve fat and lipid-like. The penetration of formaldehyde is very strong, the shortening rate is not large, and the price is low. Defects: effect on the skin, high concentration inhalation of respiratory severe effects and edema, eye effects, headache. 3, thermal sterilization microorganisms have their suitable growth temperature, more than the maximum growth temperature scale, it will cause death. Therefore, heating has become one of the most widely used and effective methods in sterilization and disinfection. All the hose and fixed tube connecting the material need to undergo steam sterilization for 30min before use. Strengths: the steam has a broad spectrum, easy access, non-toxic, non-corrosive, and outstanding penetration. Defects: steam simply forms a thin film, heats up slowly and consumes power. Beer can be pasteurized and continued for 20 minutes at 60℃. However, due to the long heating time, it has certain influence on the flavor, nutritional components and colloid stability of the product. I believe that after reading the above-mentioned common sterilization and cleaning methods for beer equipment introduced by Shandong trano, it should be clear that the above-mentioned sterilization and cleaning methods also have some defects, it is necessary to choose according to your actual situation. I hope that the above contents can help everyone. It is recommended that the merchants regularly carry out regular maintenance and maintenance of the equipment to extend its service life as much as possible.
