The final moisture content which was 8.90 wt.% (wb) in the new
fluidized bed dryerwas almost the same as that in the conventional fluidized
bed dryer (8.88 wt.%, wb). However, without inert particle addition,
the new fluidized bed dryer had a higher biomass particle density
and required no separation of dried sawdust from the sand. This makes
the system more compact and economical.
