Using the model assumptions can significantly increase the quality of the description of the material moisture due to the potential of moisture in the material. This work is devoted to a comparative evaluation of models of equilibrium moisture content in wheat. The purpose to choose the most informative model of moisture in building materials.

This paper presents a method of spline approximation for a generalization of the numerical modeling and obtaining of multi-dimensional criterion model of drop formation hydrodynamics.

The article is devoted to the evaluation of the effectiveness of local suctions. The article describes approaches to its definition and mathematical description. The method of large particles has been used in the simulation of impurities diffusion in the working area problem.

This work is devoted to assessing the accuracy of the parameters of equilibrium models of food materials in the hygroscopic region, which are nonlinear coupled with multifactor of these models. Two-dimensional expanse of moisture content of temperature and the activity of water in wheat has been used as experimental data.

The article is devoted to the development of the diagram of thermodynamic state of gas-vapor mixture of acetone and nitrogen. The application of the developed diagrams for modeling of the process of condensation of acetone from a mixture with nitrogen has been considered. By the means of the phase diagram the number of condensed acetone at an optimum temperature for the simulation results of the condensation process has been determined.

The article studies the process of the final distillation of acetone-oil miscellas in the cleaning technology of phosphatidic concentrates using an inert component nitrogen. A model of nitrogen purging through the layer of treated miscella in deodorizing camera at the final stage of distillation has been considered. The specific number of moles of nitrogen supply to the number of moles of oil has been determined.

The complex vegetable oil processing line, including membrane processes for core operations that allows to increase the output of refined oil and to get high-quality unfatty phospholipids, fatty acids and biofuels have been justified.
