THE IMPROVING METHODS FOR INCREASING THE EFFICIENCY OF AN EXPERIMENTAL ELECTRIC PASTEURIZER AT HOME Gabil Mammadov, Rasim Saidov, Rovshan Hajiyev, Mehriban Huseynova, Urfan Taghiyev, Gahira Allahverdiyeva, Aynur Iskenderova, Zohrab Seyidov Eureka Physics and Engineering, 2025 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 Republic of 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.
DEVELOPMENT OF AN ELECTRIC MILK PASTEURIZER FOR FARMING Gabil Mammadov, Zohrab Seyidov, Rasim Saidov, Rovshan Hajiyev, Mehriban Huseynova, Urfan Taghiyev Eastern European Journal of Enterprise Technologies, 2025 The object of study is the milk pasteurization by way of improving construction parameters. Main target experimental substantiation of the design and technological parameters of an improved heater based on the use of an induction heater and conducting production tests of an experimental pasteurizer, evaluating its performance and quality indicators. This study is in the nature of a search for a method to preserve the milk quality. The study consists of the direction of improving the flow-through and parallel-cumulative induction pasteurizer, the design of the continuous-acting induction milk pasteurizer, the substantiated mathematical dependences of the interrelationships of its effective design and operating parameters, as well as the method of technical parameter reporting and evaluation of the effect of the improved experimental pasteurizer on the basic milk properties. The bactericidal phase before and after milk pasteurization in an experimental heater is as follows: for fresh milk (t=300 °C), the duration of the bactericidal phase is 2 hours, with self-cooling of fresh milk from 370 °C to 200 °C, the duration of the bactericidal phase is 3 hours, and when cooling milk to 8...100 °C – 8 hours. For pasteurized milk (t=300 °C), the duration of the bactericidal phase is 17 hours, and when the milk is cooled to 8–100 °C, the duration of the bactericidal phase is 30 hours. The proposed induction pasteurizer ensures efficient milk pasteurization produced on dairy farms, ensuring the possibility of direct delivery of the product to a retail chain or delivery to a processing plant without damage, which provides economic benefits to the farm. The proposed induction pasteurization unit is recommended for use not only in small and medium-sized farms, but also in centralized district milk collection points
THE STUDY OF THE EFFICIENCY EVALUATION OF THE VENTILATION SYSTEM OF THE POULTRY HOUSE IN THE SUMMER Rovshan Hajiyev, Mehriban Huseynova, Urfan Taghiyev, Gabil Mammadov, Gahira Allahverdiyeva Eureka Physics and Engineering, 2024 With the onset of cold weather, heat transfer through the walls and especially the roofs of bird rooms, unlike in the summer period, increases significantly, which leads to a sharp decrease in warm indoor air. Therefore, in order to maintain the regulatory conditions of the ventilation system, it is reduced to a transitional mode, and then to a minimum ventilation mode. Low ventilation repeatability limits inside the building determine the minimum volume of air supplied by the ventilation system. The economic and production efficiency of poultry farming is related to the premises and climatic conditions, which can seriously affect the well-being of broilers. Heat stress contributes to behavioral, physiological and biochemical changes in broilers, which leads to economic losses.
 The purpose of this study is to influence the annual efficiency of the poultry house ventilation system, mainly in summer, in order to evaluate the efficiency during the reconstruction of the cooling system, that is, to improve the ventilation system of the room, as well as to give an economic assessment of waste disposal technology.
 Energy– and resource-saving, environmentally friendly technologies and technological tools, plastic-type recuperators, a bird droppings removal system, as well as lighting and irrigation processes were taken as the object of the study. In conducting our research, let’s use classical and special methods, including a decomposition method for analyzing the functional use of recycling technology, a logical and linguistic method for assessing the safety of nitrogen during disposal, microclimate technology, nutrition and storage.
 Based on the mathematical model, a computer research methodology was developed to improve the energy efficiency of the poultry house. Using a computer program, the number of LEDs (α=200, I0=20 cd) for an enclosure measuring 66×12 m is N=273 pieces, and the number of LEDs (α=200, I0=20 cd) for a building measuring 78×18 m is N=259 pieces. The design parameters of the illuminators are justified
APPLICATION OF INTENSIVE TECHNOLOGIES FOR IMPROVED PRODUCTION PROCESSES IN POULTRY FARMS Rovshan Mustafa Hajiyev, Kamala Salmanova, Gabil Mammadov, Urfan Taghiyev Eastern European Journal of Enterprise Technologies, 2022 One of the important problems in the modern world is to provide the population with high-quality food. So, today the agricultural sector faces the main task of increasing the production of agricultural products, as well as the use of agricultural waste. Poultry farming is one of the main branches of the agricultural sector. The main task facing farmers is to improve the conditions and technology for feeding and keeping farm birds, and one of the important tasks is the state of indoor air in this regard, the problem remains open. Therefore, the main way to solve this problem is the preferred transition to intensive technologies in order to realize the efficiency potential in poultry farming. However, the intensification of the area increases the anthropogenic load on the environment. The main source of environmental risk is the systems of disposal of bird droppings. Our research has shown that 85 % of the negative impact on the environment is caused by poultry and animal husbandry waste. Lighting also plays an important role in poultry farming. Thus, lighting is the basis for electricity consumption. Both natural and industrial lighting is important for the physiology of birds and their development, but, unfortunately, it is quite energy-intensive. In this regard, the idea of solving this problem is being created, it is the development and application of new, efficient, inexpensive and environmentally friendly technologies that are important for large-scale research. Therefore, it is necessary to take into account that most poultry farms are equipped with simple mechanical ventilation systems without cooling. So, an increase in productivity is possible through the introduction of intensive technologies, while the economic assessment of the use of evaporation plants, the disposal of bird droppings and LED lighting can be of practical importance.
UTILIZATION OF POULTRY DROPPINGS IN TERMS OF NON-WASTE TECHNOLOGY Rovshan Mustafa Hajiyev, Rasim Saidov, Gabil Mammadov, Gahira Allahverdiyeva, Urfan Taghiyev Eastern European Journal of Enterprise Technologies, 2022 The processing of poultry droppings under anaerobic conditions, in special hermetic reactors – methane tanks is considered to be the most promising technology in terms of efficiency in agrochemical, environmental, and energy fields. Organic fertilizer in the methane tank is in the form of concentrated liquid, purified from disease causatives and weed seeds. It is easily absorbed by fermented plant mass and contains macro and micronutrients, amino acids and phytohormones that stimulate the development of the plant. The rare utilization of such facilities is explained by the lack of funds for their purchase. On the other hand, it is assumed that biogas is not a dominant factor in terms of economic efficiency, and organic fertilizer is also important. In this respect, the utilization of poultry droppings has also gained practical relevance. The paper covers the discussion of the feasibility of utilizing poultry droppings as a non-waste technology. The methodological approach is based on the evaluation of more rational technological projects. In logical modeling, the rules drawn up by highly qualified specialists are used. The rules determine how to act in a certain situation. Such rules are considered favorable for non-skilled performers. The results of the studies have allowed analyzing the dynamics of nitrogen preservation depending on the utilization technology of poultry droppings and impact factors. Based on a mathematical model, a computer methodology for research on improving the energy efficiency of a poultry farm has been developed. The number of LEDs (α=200, I0=20 kd) for a 66×12 m poultry house using a computer program N=273 pcs., the number of LEDs (α=200, I0=20 kd) for a building with dimensions of 78×18 m N=259 pcs. The design parameters of the lamps are substantiated
ANALYSIS OF THE MAIN DESIGN AND OPERATING PARAMETERS OF THE DEVICE FOR THE FERMENTATION OF BIRD DROPPINGS Rovshan Hajiyev, Rasim Saidov, Gabil Mammadov, Urfan Taghiyev, Gahira Allahverdiyeva Eureka Physics and Engineering, 2022 The study on the utilization of poultry droppings put forward the need for the constructive and technological improvement of the biofermentation device. A drum-type bioreactor better meets the requirements for the technological process of eco-friendly biologically active fertilizer production from livestock and poultry wastes. However, the great size of the heat transfer surface of the bioreactor drum and its significant ejection momentum during spinning require quite a lot of energy. To decrease this consumption, the main constructive parameters should be optimized. The main reason is the sharp increase in prices for mineral fertilizers, the weak economic condition of most farms, the lack of advanced processing technologies and the use of organic fertilizers.
 Our aim in these studies was to analyze the types of design and operating parameters of the device for the fermentation of bird droppings. To this end, we conducted a study on the disposal of bird droppings, and also put forward the need for constructive and technological improvement of the biofermentation device. One of such ways to solve the problem was a drum-type bioreactor, which, according to our research indicators, better meets the requirements for the technological process of producing environmentally friendly biologically active fertilizers from animal husbandry and poultry waste, however, the size of this equipment of the heat transfer surface of the bioreactor drum and its significant emission pulse during rotation require a rather large waste of energy. To reduce this consumption, it is necessary to optimize the basic design parameters.
 Devices that work continuously were recognized as the most promising. They fully meet the technological and operational requirements
