For the accurate design of a system in which a transfer process such as drying is taking place, the effects of the dominant variables in the system must either be determined experimentally or predicted from reliable empirical or theoretical correlations. Reliable predictions may be made when the transfer process is occurring under steady state conditions, as in the constant rate period of drying. When the transfer rate varies and depends on the system being investigated as in the falling rate period of drying, the effect of the controlling factors should be determined experimentally. In the present work, drying tests have been conducted using two systems which are distinguished by the type of design procedure necessary for each system. The two series of drying tests were designed: (1) to permit the prediction of heat and mass transfer rates during the constant rate period of drying of spheroidal Celite pellets arranged in a packed bed (2) to apply the "factorial" method of experimentation to the drying of barley in a rotary dryer.
