Basic regularities of the filtration drying of wheat grain
Keywords:wheat grains, moisture content, hydrodynamics, heat exchange, diffusion, drying kinetics
This paper discusses the results of experimental investigations into the hydrodynamics and heat exchange specific to the filtration drying of wheat grain. The result of experimental investigations into the hydrodynamics has been generalized based on the inner problem, exterior problem and a mixed problem of hydrodynamics. The experimental data representations in the form of dimensionless numbers are easy-to-use in practice and enable determine the energy cost and the economic feasibility of the process. Determining the optimal parameters of filtration drying process was ensure by the investigation into heat exchange specificities and their generalization in the form of dimensionless numbers that would enable to compute the heat rejection factors, with the filtration modes and physical parameters of the heating medium being known. Obtained are the design dependences to determine the internal diffusion coefficients against the temperature of a heating medium and the initial moisture content of grains. The resulting design dependency may be used to predict the duration of the wheat grain filtration drying. Determined are the rational modes of drying for seed grain and food grain.
