The obtained data shows in Figure 10.5. The growth of Gibberella
fujikuroi on extruded wheat bran granules for the production of
gibberellic acid. A bed height of 40 cm was used. The temperature
in bed was control within the range of 25 to 30°C.
The hotspots represent regions that were receiving poor aeration due
to channeling. The bed temperature exceeded the temperature of the
outlet air (compare Fig. 10.5(b) with Fig. 10.5(c)).
