In summer, most people will like to drink beer, which is an imported beverage. Therefore, special attention should be paid to whether the sterilization and cleaning of beer equipment are safe and careful in the cleaning process. As we all know, what kind of sterilization and cleaning method is adopted in the brewing of this equipment has an important influence on beer fermentation. Then everyone knows how to sterilize and clean it. Is there any way? Shandong trano to introduce the common sterilization cleaning methods are divided into the following types. 1. Ultraviolet sterilization ultraviolet sterilization effect on water is very useful. Its activity depends on pH and temperature and is widely used in the preparation system of sterile water. Benefits: no residue and gas, low toxicity. Defects: poor permeability, sterilization effect depends on the turbidity of water, and there is no residual activity, which is easy to cause bacteria to grow again. 2. The sterilization effect of formaldehyde sterilization in beer equipment is that it has a reduction effect, can inhibit bacteria or sterilize, and can combine with amino groups of proteins to denature proteins, thus destroying the cytoplasm of thallus. After washing clean reproduction tanks and fermentation tanks with NaOH solution and rinsing them with clear water, formaldehyde solution with a mass fraction of 2% shall be selected for sealing for 2 hours, and then rinsing them with clear water for later use. Benefits: soluble in water and ethanol, formaldehyde is easy to combine with amino groups in protein, making protein agglomerate, gelatin agglomerate and arrange fixation. Formaldehyde can preserve fat and lipid. Formaldehyde has strong permeability, small shortening rate and low price. Defects: effect on skin, severe effects of respiratory tract and edema, eye effects and headache when inhaled at high concentration. 3. Thermal sterilization microorganisms all have their suitable growth temperatures, which will cause death when they exceed their maximum growth temperature scale. Therefore, heating has become one of the most widely used and effective methods in sterilization and disinfection. All the connecting materials of the hose and the fixed tube in the use of 30min before the steam sterilization. Advantages: Steam has a broad spectrum, easy to obtain, non-toxic, non-corrosive, and has outstanding penetration. Defects: steam simply forms a thin film, which heats up slowly and consumes power. Beer can be pasteurized 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, we should choose according to our own actual situation. We hope the above contents can help everyone. We suggest that businesses should regularly maintain the equipment and extend its service life as far as possible. : Beer equipment
