Tarlev V. Scientifical basis of stone fruit drying by means of UHF and SHF

The core of thesis consists in scientifical and practical analysis as well as improving the stone fruit drying process using UHF and SHF. To develop the drying process of stone fruits there have been determined such electro-physical parameters of stone fruits as tg ? and ?', as well as the dependence of these parameters on the field frequency, the humidity and the temperature of the product. There has been defined the kinetics of drying process using UHF and SHF for such stone fruits as apricot and cherry. There have been elaborated some mathematical models for optimization of apricot and cherry drying using UHF and SHF. There has been defined that using combined power supply-convection + UHF and SHF intensifies the process of drying in some times. There have been revealed the essential technological regimes of apricot and cherry drying. There have been created the lines technological schemes for apricot and cherry drying by means of UHF and SHF drying. There has been shown the technique of dried fruit quality indexes optimization. Key words: drying, combined power supply, convection, UHF and SHF currents, apricot, cherry, line, quality.
