CONVECTION DRYING OF POROUS MATERIAL

The kinetics of convection drying of flat tiles has been investigated experimentally in an industrial tunnel dryer. It was found that an exp onential model of the type: B(t) = a exp (-bt2) (-dB(t)/dt) = 2btB(t) has physical significance and correlates the kinetics of the whole til e-drying process. Applying the maximum allowed drying rate curve obtai ned for a flat tile in the first period of drying, a grapho-analytic m odel for the optimal management of the process has been developed.
