The material is
conveyed through a
circular tube
arrangement. This
design is for low
volume throughputs.
The Product stream
is sucked together
with the hot air
into the blower.
Passing the blower,
the product is
turbulent contact
with the hot air,
and blown through a
circle shaped drying
section of about 30
meters in length to
create the necessary
dwell time to allow
the hot air to
absorb the humidity.
In this section a
thermal sensor has
been installed
constantly measuring
the temperature. The
temperature is being
displayed in the
electric panel. (If
heating registers
are being used, the
actual temperature
is compared with the
pre-adjusted
temperature and
corrected if
necessary. This is
achieved by
switching heating
elements in the
heating register on
or off). Depending
on the desired
residual moisture
and the kind of
material, the
temperature measured
should range between
400C and 800C. A
pressure control
device constantly
checks if there is
any airflow. In case
of a material jam
this pressure
control device would
react and switch off
the warm air supply.
After the drying
section the material
goes into the
separation cyclone
which again
separates material
from the warm moist
air.
To create the
necessary
temperature we do
offer several
alternatives: •
electrical heating
with heating
registers • gas
burner (recommended
for minimizing the
operational costs) •
steam
