Results of pilot studies of the car for grain processing
The random balance method was used to select the most significant factors in degree of their influence on the optimization parameter - final moisture content of the material: initial moisture content of the material, power of IR-radiators, machine productivity, and shaft rotation speed. Planning matrix was realized, statistical analysis of the results was carried out by the software Statistica 10.0. On the basis of experimental studies, a mathematical model of the technological process of wheat processing in a peeling and drying machine was obtained. Determined optimal design and operating parameters of the developed peeling and drying machine: at initial moisture content of the material of 19% (strongly remoistened grain), optimization parameter (the final moisture content of the material) reaches the minimum values - 15.0-15.5% (an optimum zone), with the minimum machine productivity 500 kg/h, shaft rotation speed 1350-1400 rpm and power of IR -radiators 4 kW.
