Annotation

Analyzed the accuracy of the numerical simulation of unsteady diffusion during cooking of grain grits, made by the grid method by comparing the results with analytical solutions. Use the known analytic solutions of nonstationary diffusion at saturation grain grits. Analytical solutions are obtained by the method of divide of variables and solutions, which are based on the Laplace transform, Fourier transform and complex sine-Fourier transform on semi-infinite interval. Numerical solution fulfilled by the grid method for the implicit scheme. The diffusion coefficient of bound moisture in the material is calculated from the known Arrhenius equation, which takes into account the activation energy and pre-exponential factor, account of its temperature dependence. In the boundary conditions, the initial concentration of diffusing assumed to be zero. Tenderize particulate material thickness is 1 mm, which corresponds to a degree of grain refinement at a 90% confidence pass through a sieve of 1 mm diameter. Shows the resulting simulation graphics depending on the concentration distribution of diffusing coordinates for various periods of time, showing good qualitative and quantitative agreement between the numerical results with analytical methods for solving the equation of unsteady diffusion. It is shown that the known solutions do not take into account analytical example of cooking with the temperature change, swelling of starch granules and detachment of the outer layers, which take place in the actual process. To describe the process of cooking grain grits recommended grid method for the implicit scheme, taking into account the change in the temperature of the process, the swelling of the starch granules and starch separation of layers, the results of calculations which are consistent with experimental data on the cooking of grain grits.
