Korobka S. Substantiation of parameters and working conditions of fruits heliodrier

The thesis presents results of solving scientific and applied problems consisting in substantiation of parameters and working conditions of the fruits heliodrier aimed at raising energetic efficiency of the technological process of drying small volumes of fresh fruits collected from private farmsteads and farms. The research is focused on the application of solar energy for fruits drying which is acceptable for the latitude of Rivne region dislocation characterized by 3,41 kW h/m2 average annual solar radiation power for a light day. This allows to achieve 1,5...2,3 kW h power from 1 m2 per 1 day. The thesis managed to get analytical equations for calculating construction and technological parameters of fruits driers and suggested parametric group of mini - heliodriers. It developed mathematical model of the technological process of fruits drying in heliodriers; studied the influence of heliodriers constructive and technological parameters and environmental physical parameters on the modifications in thermo-mass exchange characteristics of the process of fruits drying; evaluated energetic and economic efficiency of the given scientific and technical project and developed the ways of its introducing into industrial production.
