Drying rate

The condition that is most highly related to the amount of cracking is the drying rate. In general, the higher the air temperature the greater the drying rate. As shown in Fig. 5,in order to hold the amount of cracking below a certain level, the higher the initial moisture content the lower the ventilation air temperature must be held. In addition ,the lower the absolute humidity of air, the lower the ventilation air temperature must beheld. Figure 6 shows the relation between the initial moisture content and the limiting average drying rate.
