Investigation of the main design and operating optimal parameters of the micronizer when processing grain feed with infrared radiation

The article substantiates the main characteristics of the studied device of micronization in the processing of grain feed. Here, an experimental micronizer that micronizes feed grain was taken as the object of research. A multi-factor experiment was also conducted to determine the optimal distance of the infrared lamp from the quartz glass and the optimal power of the light flux. The experiments were carried out on an experimental installation equipped with a “Legrand” dimmer, which allowed changing the radiation power of the lamps. For the experiments, a symmetrical Box-Behnken design was selected from a rotatable, composite second tier. The studies were conducted on wheat, barley and velamir. The results of the experiments carried out to optimize the main design and operating parameters of the micronization plant are shown in the graph. Along with this, a mathematical formula reflecting the dependence was obtained during the statistical processing of the experimental estimates. The resulting mathematical expression and graphical analysis reflect the heat process under study and can be used in practice. The graph shows that the optimal values for wheat micronization are the lamp distance to the object b = 70 mm and the lamp power Nlam = 1.0 kW.
