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.
