Basing on the analysis of differential equations system using partial derivatives proposed by A. V. Lykov, one proposes the calculation of soft regime dryers, using temperatures lower than boiling one. For a rational take place of drying or heating process one should constantly heat the air to exclude water vapors condensation on the waveguide’s surface and provide proper moisture elimination from evaporation zone. The calculation is based on specific thermo-physical properties of the processed product. The obtained correlations show the repartition of temperature and moisture content along the dryer length. Basing on the analysis of the common solution for the temperature repartition and specifying the values of the admissible temperature (using technological conditions or others), one can calculate the level of used UHF power. |
