Abstract: The study aimed to optimise the operation of heat exchangers and mixing machines to improve the efficiency of production processes. An experimental approach with models that describe the processes of heat transfer, hydraulic resistance and mixture homogeneity was used to determine the optimal equipment parameters. The study showed that optimisation of the operation of heat exchangers can lead to a significant increase in energy efficiency and a reduction in operating costs. The best results were achieved at a coolant temperature of 90°C and a pressure of 5 bar, which resulted in a maximum heat transfer of 350,000 W. The study determined that reducing the hydraulic resistance to the optimum level can reduce energy costs for pumping coolant by 15%. The study also showed that to achieve maximum homogeneity of the mixture in mixing machines, the optimal rotation speed is 400 rpm. This resulted in a mixture homogeneity index of 16. The study determined that the temperature of the components fed into the mixing machines has a significant impact on the final product quality. For example, the optimum temperature for certain components had reduced mixing time by 10%, which had contributed to an increase in overall productivity. The integration of automatic control systems, such as the automatic control system, allowed for real-time monitoring and adjustment of equipment parameters, which further increased the efficiency of production processes. In addition, the study determined that comprehensive optimisation of the parameters of the devices’ operation allows for an increase in the duration of their life cycle, reducing the frequency of maintenance by 20%. Optimisation of the operation of heat exchangers and mixing machines significantly increases production efficiency and the quality of final products, contributing to cost reduction and increasing equipment reliability
