TRANSCRIPT
TRAY DRIER
MODEL: BP 772
T
SOLTEQ®Equipment for Engineering Education & Research
HIS Tray Drier (Model: BP 772) has been designed for student laboratory training programmes in unit
operations. The unit resembles the most commonly used industrial method of drying solids in bulk where
hot air stream is passed over fixed trays of wet material. Students will able to vary the operating conditions
Air is drawn into the chamber by means of axial flow
fan located at one end of the tunnel. The fan speed
may be regulated to vary the air velocity through the
drier. The unit comes with a bank of electrically heated
elements upstream of the drying compartment to
increase the air temperature. The heaters come with a
variable power input.
The 0.04 m3 drying compartment is fitted with a
transparent access door. A rack of trays capable of
holding approximately 3 kg of solids, is suspended from
the arm of a digital balance which is mounted on top of
the drying compartment. The ducting upstream and
downstream of the drying compartment has been
designed to produce a uniform airflow over the trays.
The unit comes with instruments for the measurement
of temperature and humidity before and after the
heating/drying section.
The complete unit is mounted at bench height to allow
convenient operation and measurement.
and collect data to demonstrate both the theoretical and practical aspects of industrial drying practice.

SAFETY FEATURES
The unit comes with these safety features:
♦ Earth Leakage (Residual Current) circuit breaker
for protection from electric shock.
♦ The heating elements may only be switched on
when the axial flow fan is operating.
♦ The fan comes with a preset minimum speed in
order to prevent damage to the heater elements
through overheating.
♦ The heater elements are further protected by a
temperature controller in the event of interruption
of the air flow.
EXPERIMENTAL CAPABILITIES
♦ use of psychrometric charts
♦ energy balances
♦ mass balances
♦ demonstration of drying rate regimes
♦ heat and mass transfer analogies
♦ drying tests on solid for industrial use
♦ effect of temperature, air velocity on drying rate
