To obtain the product, the GBR was dried at the temperatures of
130 and 150 C for both drying media. The static bed height was
fixed at 10 cm and the superficial fluid velocity was in the range
of 3.5–5.7 m/s. The samples were taken out from the dryer at predetermined
times to measure grain temperature and moisture content.
Grain temperature was measured by putting the sample into
a well insulated container and inserting a thermometer into that
container.
