Optimal<br>regimes of vacuum-atmospheric drying of the given materials are developed. Results of vacuum and atmospheric<br>drying of large-dispersed materials are studied. Depending on height of layer of drying material, pressure of medium<br>into vacuum camera, temperature level of drying the numerical values of coefficients of heat and mass transfer and<br>equations of heat and diffusion Nusselt criterions are received. Comparison on adequacy to real conditions is<br>conducted in order to check the criterion equations. Meanings of experimental and calculated data of heat and mass<br>transfer coefficients have satisfied convergence.</p> ER -
