Abstract:

Belt dryers are widely used in different industries. Rubber drying, the same as the functioning of most chemical reactors, is a set of interrelated thermal and hydrodynamic processes. A mathematical model of the drying process of porous rubber belt is presented. It is obtained on the base of the laws of conservation of mass and energy in the differential and integral forms taking into account the kinetics of water evaporation. It is considered a steady state operation of the drying chamber. It is possible to determine the thermal and hydrodynamic atmosphere in the drying chamber (temperature distribution, moisture content) in case we know the parameters of the sectional dryer, its geometrical dimensions, power heaters, if the boundary conditions at its inlet and outlet (temperature and mass flow rates of the phases; tape rubber dimensions and its porosity, moisture content) are set and if the boundary value problem is solved.
