The GBR had an initial moisture content of 52% dry basis (d.b.).
The GBR was divided into two portions. The first portion was prepared
for the reference sample which was dried in shade. The
remaining portion was dried in a fluidized bed dryer with superheated
steam (SHS) or hot air (HA).The fluidized bed drying system
used in this study is shown schematically in Fig. 1.
