This study is in the nature of a search for a method to preserve the quality of milk. In this regard, it is possible to conduct studies on reducing acidity. In the Azerbaijan, the delivery time of milk from dairy farms to a dairy plant often exceeds the bactericidal period of milk. In this case, 30% of the milk entering the plant has an increased acidity (19–20%). In this regard, it must be treated heat before leaving treated heat before leaving the farm. One of the operations in milk production is its heat treatment. However, the use of steam pasteurizers on farms and in other types of agriculture requires additional costs for steam generation equipment, ventilation systems, and sophisticated automation. In this regard, the issue arose of increasing efficiency and reducing operating costs during the heat treatment of milk. The aim of this study is to theoretically and experimentally substantiate improved design and technological parameters for milk heat treatment under farm conditions. Experimental samples were studied using induction heating, standard methods and verified the operation of our developed experimental milk pasteurizer under industrial conditions. Therefore the bactericidal phase before and after pasteurization of milk in an experimental heater is as follows: for fresh milk (t = 30°C), the duration of the bactericidal phase is 2 hours, with self-cooling of fresh milk from 37°C to 20°C, the duration of the bactericidal phase is 3 hours, and when cooling milk to 8…10°C – 8 hours. For pasteurized milk (t = 30°C), the duration of the bactericidal phase is 17 hours, and when the milk is cooled to 8–10°C, the duration of the bactericidal phase is 30 hours. The novelty of this study lies in the analysis of the direction of improvement of an electrically efficient flow and parallel pasteurizer. The design and technological innovations of the induction pasteurizer heater were approved by the Intellectual Property Agency of the Republic of Azerbaijan on the basis of patent No. U 2020 0028.
