Theoretical and experimental backgrounds of oscillating infrared drying dispersed materials

The research on the influence of the initial moisture content of seeds, of the duration of IR drying, of temperature regime on the effect of stimulation and keeping the effect with time, was carried out. A mathematical model for the dynamics of heating a seed layer, taking into account the moisture evaporation, is developed. Paper presents experimental data on mass conductivity properties for a dried layer of seeds, the recommendations for process equipment design are given

Drying the corn in a farm heat pump dryer with fluidized bed

[EN] The possibility of using a heat pump as a part of on-farm drying plant is considered taking drying of corn grain as an example. The methodology for kinetic calculations of a drying plant with a batch fluidized bed for granular materials is developed. These calculations are based on the use of an analytical solution for the problem of mass conductivity and taking into account the time-related changes in drying agent parameters over the layer height. To determine the concentration dependence of the mass-conductivity coefficient, a zonal method has been used.Rudobashta, S.; Zueva, G.; Dmitriev, V.; Muravleva, E. (2018).
