The results of survey of the process of cooking and distillation Ltd. “Standard Alcohol” (Kabardino-Balkar Republic, Nartkala). The simulation of a two-step cooking of corn grits. In the considered model of temperature change in time, and detachment of swollen starch granules with a surface layer material tenderize. Solution of the system of differential equations satisfied by the grid method for the implicit scheme. Dependence of the diffusion coefficient on temperature is given by the Arrhenius equation. Defined parameter identification model – the diffusion activation energy of bound moisture, which amounted to 22,412 kJ/mol. Given the results of chromatographic analysis of the mash, distillate fusel oil and sivushnoy water. Described flowsheet preparation of corn grits, and saccharification of cooking. A comparison of exploded corn brew developed at Distilleries Ltd. “Standard Alcohol” (Kabardino-Balkar Republic, Nartkala) and “CH Sunrise” (Republic of Adygea, Maikop) at high temperature and low temperature cooking, respectively. Modeled in HYSYS environment integirovat six column distillation setup consisting of columns: mash, ethereal, distillation, aldehyde- ethereal, fusel and final purification column operating mode distillation. For the finished product – fusel oil – set decanter. Discussed features of this scheme from the famous. The block diagram of the process in an environment distillation HYSYS. Estimates of the quality of rectified alcohol consistent with production. Developed brand alcohol “Lux” with the content of 2-propanol was less than 1 mg/dm3. Shows photographs of corn grits, mash and fusel oil.
