While moving along the milk-conducting systems in a milking machine, milk is in contact with the inner surface whose area exceeds 20 m2. That leads to the formation of protein-fat biofilms of contamination, which are a nutrient medium for the development of microorganisms. With insufficiently effective cleaning of these contaminants, in the periods between milking, the number of microflorae located in milk-conducting systems increases by tens of thousands of times. When cleaned with ineffective cleaning agents, mineral elements from milk are adsorbed on the surface of a protein-fat bio-film, which are subsequently compacted, changed, and converted into milk stone. In this case, the technical implementation of milk conducting systems is of critical importance. It has been established that a milk line made from any material is better cleaned with a hot washing solution than a cold one. Thus, with an increase in the temperature of a washing solution from 60 °C to 85 °C, the cleaning time of the milk line is reduced from 9.5 minutes to 1.5 minutes, or by 6 times. It was established that during the washing phase of a milk line there is a significant decrease in the temperature of the washing solution (≈30 %), which reduces the effectiveness of cleaning the parts of the system. Therefore, there is a need to maintain the solution temperature throughout the entire cleaning process. It is proved that the specific energy of adhesion of pollution in water is 2 times higher than that in a washing solution. With an increase in the temperature of the solution for every 10 °C, the decrease in the specific energy of pollution adhesion is on average 13 %. With an increase in the period after the end of milking before washing the milk line, the specific energy of its purification increases. The study reported here could lead improve the productivity of milking machines and the quality of the resulting product. That involves designing milking and dairy equipment from innovative materials.
Ozone enters into chemical reaction with many organic compounds. Ozone is a very strong oxidant. It oxidizes most of the elements to higher oxides. In the oxidation reaction by ozone activity second only to fluorine, its oxide and free radicals. It is formed from oxygen by absorbing heat in this case, and, conversely, when the expansion goes into oxygen, giving off heat. The main method of obtaining ozone for practical purposes is electrosynthesis. In industrial conditions for using ozone and corona discharge barrier. Ozonizers corona discharge can significantly increase the efficiency of ozone by reducing capital and operating costs for the process equipment and ozonation. Research shows that ozone air ozonator pulsed mode increases the resistance of animals to the action of microorganisms factor. In animals and poultry in industrial production often develop diseases caused by pathogens factor. These diseases mainly occurring symptom of lesions of the respiratory and digestive systems. In many countries today conducted research using ozone, and the results of these studies are published in the course of scientific-metric database. For normal growing animals, especially young animals, premises should be thoroughly disinfected. Disinfection is required for all technological facilities as livestock and poultry. Experimentally found that ozone has a bactericidal effect (for example, test cultures E. coli) on different surfaces (wood, Petri dish) considering its concentration and exposure. The results of influence of different concentrations of ozone in ozonair mixture is fed into the container of the Petri dish, and time impact on survival of microorganisms provides a fairly accurate prediction of the results of impact parameters ozonation. Key words: ozon, ozone therapy, Escherichia coli, disinfection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
