Yakushenko E. The improving of energy efficiency of the drying process of husks of grapes in mass transfer module with conductive supply of heat

Purpose - improving of power efficiency of the drying process in the mass transfer module with use of conductive heat supply and ground of rational modes of husks of grapes drying. Object of research - the drying process in the mass transfer module with conductive heat supply. Subject of research - mass transfer module with different types of fuel elements and drying kinetics of husks of grapes. Research methods - experimental methods of studying the kinetics of heat-and-mass transfer processes in mass transfer module with conductive heat supply; standard methods of the determination of quality indices of husks of grapes during the drying process; modern methods of mathematical processing of experimental researches; methods of mathematical physics for the modelling of heat and mass transfer in the drying process. Scientific novelty of the results: the rational sphere of use energy efficiency of convective and conductive heat supply to the mass transfer module is determined; the improvement of energy efficiency of drying process under the division of functions of heat and mass transfer in the drying module, in which the energy input is carried out by the interior fuel elements, and the moisture is absorbed by the external air stream at ambient temperature is proved; new energy efficiency index of dryers - productivity by evaporation moisture, which is referred to heat rate for the process is proposed; the optimal duration of the drying process with pre-heating of the material on the base of the maximum efficiency of the process is established. Results of the research are introduced at enterprises and in the educational process. Field of implementation - enterprises of processing and food industries.
