ULTRASONIC-ASSISTED DRYING AND INTERMITTENT DRYING: A MODELING STUDY USING THE REACTION ENGINEERING APPROACH (REA)
ABSTRACT: Drying is
a simultaneous heat
and mass transfer
process which involves
significant energy
consumption. For sustainable
processing practice, ultrasonic-assisted drying
is often implemented. In
order to assist
in process design
and optimization, a
physically-meaningful drying model
is useful. The REA (reaction
engineering approach), which has
been shown to be accurate
to model several
challenging drying cases,
is implemented here
to model the ultrasonic-assisted drying
with various intensities.
The relative activation
energy (ΔEv,b) generated from
one accurate drying
experiment is used
to model the
ultrasound-assisted drying
with various intensities.
The results of
modeling match very
well with the experimental data.
The REA is
accurate to model
the ultrasonic-assisted drying.
The mechanisms of ultrasonic-assisted drying can be explained well by
the REA. A landmark for process
intensification of drying
process has been
set up by
the REA. The
model can be readily adopted in industrial settings for
process design and optimization.
