Evaluation of the process of pelleting for pre-sowing treatment of flax seeds

Abstract

The paper presents a computational method that allows to predict the process of drainage of flax seeds with expanded perlite and biohumus for complex pre-sowing treatment with preliminary irradiation of seeds in the infrared range. From a methodological point of view, in the process of seed granulation, the efficiency depends on the adhesive bond arising in the process of rolling and dispersing. To solve this problem, the calculations of mathematical models of the process of granulation of seeds and the process of dispersion of perlite with biohumus on the surface of seeds were carried out in order to obtain a finished dragee with components of natural origin and improve the sowing qualities of treated seeds and the finished product. As a result of the developed models, analytical solutions of kinetic problems for the process of precipitation of particles of a draining mixture of perlite and biohumus on the surface of flax seeds are obtained. The described mathematical model allows to determine the technological parameters of the granulation process-particle size of the granulating mixture and granulation time, for the calculation of granulating components in the development of technological equipment for granulation. The approximation of the obtained data was made, which showed the prospects and effectiveness of the ongoing developments.

Mathematical modeling of the temperature regime in industrial premises

“…At the same time, from an economic point of view, it is important to systematically reduce energy costs to ensure the required temperature regime throughout the year when the values of outdoor air temperature and natural solar radiation vary in a wide range. In scientific works devoted to the influence of air temperature in the production room on the human body, it is indicated that a decrease in temperature by 4 °C is considered sharp for the human body [19][20][21][22][23][24][25][26][27][28][29][30], but at the same time it can significantly reduce heating costs. In addition, a decrease in temperature from the normalized values during vaccination and the fight against viral seasonal diseases can lead to a decrease in workers' immunity.…”
