Optimization of the process of mixing liquid-phase heterogeneous products by mathematical modeling

Abstract

The main objective of the experimental study of all processes is the analysis, study and generalization of all available results. In accordance with the idea of a step search, the experiment was carried out in several stages. The number of stages and actions at each of them depended on the results of the previous stage and the ultimate goal of research. The ultimate goal of the study is to determine the optimal conditions for the process of mixing the liquid aggregates to obtain a homogeneous structure. Studies of the mixing process were carried out on an experimental setup created at the department. To process experimental studies, the STATISTICA 12 software package was used. To obtain the regression equation, the matrix data were processed using the Microsoft Excel 2010 software package. To optimize the process, the output parameters were converted to a dimensionless scale of desirability d. It was established that the desirability function D, which characterizes the adequacy of the obtained values, has an extremum in experiment 12 and is 0.733666. Based on the obtained data, the following parameters should be considered optimal when mixing liquid aggregates: the peripheral speed of the mixer shaft is within 4 m/s, while the mixing time is 8 s and the refrigerant concentration is 20%.

Prospects For The Innovative Development Of The Feed Industry

“…Voronezh region is traditionally included in the TOP-5 largest compound feed producing regions (Figure 2). In general, the capacity of Russian compound feed mills is estimated at 36 million tons, and by 2025 they will amount to 45 million tons (Emelyanov et al, 2020). At the same time, the country's need for compound feed is 42 million tons, and it will grow to 60 million tons by 2025.…”

“…Currently, the main criteria for evaluating compound feeds that can withstand competition in a market economy is not only quality but also the optimal cost (Emelyanov et al, 2020).…”
