Termogrammes and drying curved lines of KCK-2 silicagel in strong non-uniform electric fields, inclucling crown and spark discharge fields are shown. Equations of mass-transfer for convection molecular stream in gas phase and pull of liquid dielectric in non-uniform fields are presented. Equations of mass transfer in capillary – porous bodies are confirmed by the experiment. In accordance with theory is shown that for silicagel sample KCK-2 that have fixed size and through pores non-uniform field without discharge has an influence on inner mass and heat transfer. The field of crown and the more so spark discharge largely influences not only to inner, but to external heat and mass and mass transfer, that essentially reduces the time of drying.
